Poor data migration (38% of failures) is precisely the problem that automated data validation catches. When you’re moving hundreds of thousands of material master records, customer masters, vendor records, and BOMs from ECC to S/4HANA, manual spot-checking misses the long tail of data corruption, truncation, and transformation errors. Automated comparison scripts that verify source-to-target integrity field by field, table by table, catch what human eyes cannot. The Complexity Escalation Is Real </div>

<p>One of the most useful frameworks in Godlan’s research is the business model risk analysis. Implementation risk doesn’t stay flat — it escalates dramatically based on operational complexity:</p> </div>

<div class="elementor-widget-container">
<p>This matters enormously for SAP S/4HANA migrations. The more complex your manufacturing model, the more business logic is encoded in custom code, BOM structures, routing configurations, and pricing rules and the more surface area there is for migration defects.</p> </div>

Manual testing simply cannot cover this surface area. A configure-to-order

<p>Let’s put the Godlan numbers in financial context. If the average ERP implementation runs 189–215% over budget, and a mid-market SAP S/4HANA migration typically budgets $5–15 million, the overrun exposure is $9.5–32 million.</p> </div>

<p>Material Master isn’t glamorous. It doesn’t get keynote stage time. But it touches everything — procurement, inventory, sales, production planning, quality management, finance. A single data inconsistency in your MARA or MARC tables can cascade through your entire supply chain on day one of go-live. And when you’re migrating hundreds of thousands (or millions) of material records from ECC to S/4HANA, manual testing simply doesn’t scale.</p> </div>

<p>Material Master is often called a “<strong>migration minefield</strong>” because it is one of the <strong>most complex, interdependent, and business-critical data objects in SAP</strong>. Even small inconsistencies can cascade into major operational issues across procurement, production, sales, and finance.</p> </div>

Each view aligns with specific organizational levels and is supported by different underlying tables, creating a highly distributed data structure. This multi-dimensional complexity makes material master data one of the most sensitive and error-prone areas during migration.</p> </div>

<div class="elementor-widget-container">
<p>The data model <strong>has fundamentally shifted in S/4HANA.</strong> While the core Material Master tables (MARA, MARC, MARD, MBEW) still exist, <strong>they are no longer always the primary source of truth for transactional data.</strong> Inventory quantities in tables like <strong>MARD are now derived rather than persistently stored for reporting purposes</strong> when a material document is posted.</p> </div>

<div class="elementor-widget-container">
<p>Instead, stock values are <strong>calculated in real time using the MATDOC table and accessed via CDS views.</strong> The old aggregate and index tables <strong>have been removed as part of the S/4HANA data simplification initiative </strong>and replaced by CDS view proxies.</p> </div>

<div class="elementor-widget-container">

The Business Partner migration complicates vendor relationships. </span>
</h4>
<p class="elementor-icon-box-description">
In ECC, vendor masters lived separately. In S/4HANA, they're merged into the Business Partner framework. Material Master records with vendor-specific info (source lists, purchasing info records, quota arrangements) need their vendor references reconciled against the new BP structure. This is a cross-domain dependency that's easy to miss in isolated Material Master testing. </p>

<p class="elementor-icon-box-description">
Most ECC systems are heavily customized. Custom fields appended to MARA, MARC, or MBEW need to be carried forward through the S/4HANA Migration Cockpit (LTMC/LTMOM) using BAPI extension structures like BAPI_TE_E1MARA and BAPI_TE_E1MARC. If the field selection group assignments (T-code OMSR) aren't configured correctly, data simply won't make it to the target database. This is the kind of silent failure that only shows up if you're testing at scale. </p>

This is the layer most teams skip — and pay for dearly after go-live. The shift from statically maintained stock fields to dynamically calculated CDS views means that transactions and reports reading MARD or MARC stock data will behave differently under load. A report that ran in 3 seconds in ECC against pre-aggregated stock tables might take 30 seconds in S/4HANA if the MATDOC table has millions of entries and the CDS view stack isn't optimized. </p>

<description><![CDATA[<p>ETL Testing refers to the testing, validation, and analysis of the Extraction, Transformation, and Loading Processes that are part of ETL and ELT Pipelines. As ETL testing refers to “Data-in-Motion” Testing, the unit test architecture and principles slightly differ from “Data-at-Rest” Testing (Warehouse/DB Validation).</p>

It runs only within the Informatica platform, making it irrelevant for teams outside that ecosystem.</p><p><strong>Tosca DI:</strong> While Tosca is a popular choice for application and UI testing, Tosca DI is found to be limited in scope for ETL testing and end-to-end pipeline validation, making it a less suitable option for teams with comprehensive data pipeline testing requirements.</p> </div>

<description><![CDATA[<p>ETL Testing refers to the testing, validation, and analysis of the Extraction, Transformation, and Loading Processes that are part of ETL and ELT Pipelines. As ETL testing refers to “Data-in-Motion” Testing, the unit test architecture and principles slightly differ from “Data-at-Rest” Testing (Warehouse/DB Validation).</p>

<p><strong>iceDQ:</strong> The on-premise version of iceDQ lacks several core ETL testing capabilities that enterprise teams typically require. The SaaS version is more feature-complete but not suited for teams that need on-premise deployment.</p><p><strong>Informatica DVO:</strong> Informatica DVO is not a standalone ETL testing tool. It runs only within the Informatica platform, making it irrelevant for teams outside that ecosystem.</p><p><strong>Tosca DI:</strong> While Tosca is a popular choice for application and UI testing, Tosca DI is found to be limited in scope for ETL testing and end-to-end pipeline validation, making it a less suitable option for teams with comprehensive data pipeline testing requirements.</p> </div>

Data profiling is a crucial step in the data management process, especially in the pharmaceutical industry where accurate and reliable data is essential for making informed decisions. Data profiling involves examining and summarizing the characteristics of a dataset in order to identify patterns, trends, and anomalies in the data. By tracking aggregations and patterns in the data, it is possible to identify potential issues or anomalies that may need to be addressed in order to improve the quality of the data. </p>

<p>In the pharmaceutical industry, it is common for different vendors to provide datasets that contain information on the same subjects or entities. For example, a vendor may provide a dataset containing information on clinical trial participants, while another vendor may provide a dataset containing information on patient outcomes.</p><p>In order to accurately merge or join these datasets, it is important that the primary keys used to identify the subjects or entities are consistent. For example, if one dataset uses a 9-digit numerical key to identify participants, it is important that any other datasets that contain information on the same participants also use a 9-digit numerical key.</p><p>If the pattern of the primary keys is not consistent, it can make it difficult or impossible to accurately link records from different datasets. This can lead to errors or incorrect analyses and can compromise the overall integrity of the data.</p> </div>

To ensure the consistency of primary keys in pharma datasets, it is important to regularly monitor the patterns of primary keys and identify any potential issues. The DataOps Suite’s profile tracking node?? can be used to monitor the patterns of primary keys and alert you to any inconsistencies. This can help you ensure the quality and integrity of your pharma datasets and avoid any potential issues that could arise from inconsistent primary keys. </div>

<div class="elementor-widget-container">
Outliers are values in a dataset that are significantly different from the majority of the other values. In inpatient claims and drug sales datasets, outliers can occur in various aggregates, such as averages, standard deviations, minimum values, and maximum values. </div>
</div>
<div class="elementor-element elementor-element-4e68b86 elementor-widget elementor-widget-text-editor" data-id="4e68b86" data-element_type="widget" data-e-type="widget" data-widget_type="text-editor.default">
<div class="elementor-widget-container">
<p>Outliers can have a significant impact on the results of any analyses or modeling efforts, as they can distort the overall patterns or trends in the data. For example, if a dataset contains an outlier value that is significantly higher or lower than the majority of the other values, it could skew the average or standard deviation, leading to incorrect or misleading results.</p><p><span style="color: #1967d2;"><a style="color: #1967d2;" href="https://www.datagaps.com/etl-testing-tools/etl-validator-download/" target="_blank" rel="noopener"><span style="text-decoration: underline;">Try DataOps Suite – Free Trial</span></a></span></p> </div>

<ul><li>A few examples of how variations in min-max values and standard deviations can help identify anomalies in patient claims and drug sales datasets:<br />If the minimum value for a dataset decreases significantly over time, it could indicate an anomaly or error in the data. For example, if the minimum value for a column containing drug prices decreases significantly from one month to the next, it could indicate that the price was entered incorrectly or that the drug is being sold at a significantly discounted rate.</li><li>If the maximum value for a dataset increases significantly over time, it could also indicate an anomaly or error in the data. For example, if the maximum value for a column containing drug prices increases significantly from one month to the next, it could indicate that the price was entered incorrectly or that the drug is being sold at a significantly inflated rate.</li><li>If the standard deviation for a dataset increases significantly over time, it could also indicate an anomaly or error in the data. For example, if the standard deviation for a column containing drug prices increases significantly from one month to the next, it could indicate that the prices are becoming more variable than expected, which could be a sign of an anomaly or error.</li></ul> </div>

For inpatient claims and drug sales datasets, it is important to monitor the distribution of values across different columns and variables. The DataOps Suite’s profile node can provide various plots and statistics that can help you understand the distribution of values in your data. </div>

<div class="elementor-widget-container">
For example, if you are analyzing a dataset containing information on patient claims, you might be interested in the distribution of diagnoses across different diagnosis codes. The profile node can provide a histogram or other plot showing the distribution of diagnosis codes, which can help you identify any patterns or trends in the data. </div>

<div class="elementor-widget-container">
In addition to monitoring the distribution of values, it can also be useful to monitor a list of values (LOV) deltas. LOV deltas refer to the difference between the list of values used in one dataset and the list of values used in another dataset. For example, if you are comparing a dataset of patient claims from one year to a dataset of patient claims from the previous year, you might be interested in the LOV deltas between the two datasets. </div>

<p>One of the key benefits of using Query Builder is that it allows users to build queries visually, by dragging and dropping different components such as tables, columns, and conditions into a graphical interface. This makes it easy to see how the various components of the query fit together and to make changes or adjustments as needed.</p><p>In addition to its visual interface, Query Builder also offers a number of advanced features that can help users generate more complex queries. For example, it allows users to define and save their own custom functions, which can be used in queries to perform complex calculations or operations. It also supports features such as subqueries and union queries, which can be used to combine data from multiple tables or queries in a single result set.</p> </div>

<p><strong>For Beginners as well as Experts: </strong>While a SQL Query Builder might seem like a tool built to help professionals outside of the Data warehousing and ETL space to work with records, a huge number of QA Testers and Data Engineers use Query Builders on a daily basis to increase their efficiency and speed of creating the required queries.</p> </div>

<div class="elementor-widget-container">
<p><strong>For a Professional who has to produce and maintain a large number of queries on a daily basis</strong></p><ul><li><strong>First</strong>, a query builder can make it easier and faster to create complex queries. With a query builder, you can visually construct a query by selecting different clauses and options, rather than having to write out the entire query in text form. This can save time and reduce the risk of syntax errors.</li><li><strong>Second</strong>, a query builder can also help with query organization and management. Many query builders have features that allow you to save and reuse queries, as well as to share queries with others. This can make it easier to keep track of the queries that you have created and to collaborate with others on complex data analysis tasks. In the tool, past queries can be pulled up for reference, reuse, and specific checks.</li><li><strong>Third</strong>, a query builder can also provide useful tools and features that can help you to optimize your queries and improve their performance. The DataOps Suite also holds tools made specifically to stress test ETL pipelines and using the “Enable / Disable” functionality along with the Test Data Manager System, a user can easily optimize the query in question.</li><li style="list-style-type: none;"> </li></ul> </div>

<p>The traditional method of writing SQL queries is as follows –</p><ul><li>Identify the data you want to retrieve from the database.</li><li>Determine the tables in the database that contain the data you want to retrieve.</li><li>Determine the relationships between the tables, such as which tables are related through foreign keys.</li><li>Write the SELECT statement that specifies the columns you want to retrieve from the tables.</li><li>Use the JOIN clause to specify how the tables are related and to retrieve the data from multiple tables in a single query.</li><li>Use the WHERE clause to specify any conditions that must be met for a record to be included in the result set.</li><li>Use the GROUP BY and HAVING clauses to group records and specify conditions for the groups.</li><li>Use the ORDER BY clause to specify the order in which the records should be returned in the result set.</li><li>Functions and Aggregations can be added with specific clauses given that their grouping elements are defined as well.</li><li style="list-style-type: none;"> </li></ul> </div>

<p>It’s important to note that these are just general steps and the exact process for writing a complex SQL query can vary depending on the specific requirements of the query. Additionally, the complexity of a SQL query can vary greatly, so the steps outlined above may not be applicable to all complex queries. It’s always a good idea to consult the documentation for the specific SQL dialect you’re using to make sure you’re using the correct syntax and features.</p> </div>

<p>The video at the end shows the tool working in real time to create the query. The representation here is to showcase the speed and efficiency of using this tool as this removes a lot of fluff that engineers have to write up before even getting to the important parts of the query. In these parts, getting the naming convention correct, making sure syntax is not just valid but also what is expected, and the correct set of parameters have been set up is an error-prone if not a time-consuming task. Here, Query Builder shines to ensure that these aspects are taken care of so that users only think of the exact logic in question.</p><p>The problem statement here is that a User has to pull a set of records. The tables in question are Promotion, Product, Channel, and Cost-related Datasets. The User has to apply multiple sets of filters across all the tables, join them on the correct parent-child keys, choose the expected columns, and validate the query before testing/running it.</p> </div>

<p>While a SQL expert can build up the most complex of queries on a regular basis without any hiccups and a manager could ask the DE at hand to retrieve the required records from the database, having the tools to ensure that writing these queries is simple, fast, consistent, easy to implement and easy to maintain. This ensures that if an individual has the set of rules to be applied and access to the correct datasets, they can bring out the intended results without questioning syntax, joining keys, or aggregation columns.</p> </div>

<p>ETL allows businesses to consolidate data from multiple databases and other sources into a single repository with the data that has been modified and used during the analysis of data. This unified data repository allows for simplified access to analysis and additional processing of the data. There are many advantages of using ETL tools for the migration of data. It reduces delivery time, reduces unnecessary expenses, makes the process easy to use, and also will be simple for data migrations. Data Integration, Data Warehousing, and Data Migration are the three common uses of ETL.</p> </div>

<p class="elementor-blockquote__content">
COBOL (Common Business-Oriented Language) is a programming language that was developed in the 1950s and remains in widespread use today, particularly in the finance and banking sectors. Many financial institutions still rely on COBOL systems to manage their data and processes, even though newer technologies such as Java and Python have largely replaced COBOL in other industries. </p>

<div class="elementor-widget-container">
<p>One of the reasons that COBOL systems are still in use is that they are extremely stable and reliable. These systems have been in operation for decades and have proven to be effective at handling large volumes of data and transactions. In addition, COBOL systems often include technologies such as VSAM (Virtual Storage Access Method) and copybooks, which help to manage and organize the data in these systems.</p> </div>

<div class="elementor-widget-container">
<p>However, the hierarchical nature of COBOL and finance datasets can make it difficult to migrate this data to a modern system like Snowflake. In these systems, data is often organized in a tree-like structure with multiple levels of nested records. For example, a financial transaction record might contain multiple account details, each of which might contain multiple transaction details. This hierarchical structure can make it challenging to map the data to a more flat and normalized structure like that used by <a href="https://www.snowflake.com/en/">Snowflake</a>.</p> </div>

<p>One of the key differences between partial flattening and complete flattening is the volume of data that is produced. Complete flattening involves flattening out all levels of hierarchy in the data, resulting in a more normalized and flat structure. This can result in a significantly larger volume of data, as all of the hierarchical relationships are preserved in the data. On the other hand, partial flattening involves keeping some of the hierarchy in the data while still flattening out other parts. This can result in a smaller volume of data, as some of the hierarchical relationships are removed from the data.</p> </div>

<p>Overall, the migration of COBOL and finance datasets to a modern system like Snowflake can be a complex and time-consuming process. By using partial flattening and the DataOps Suite’s python functions, organizations can ensure that their data is accurately and effectively migrated, while still maintaining the hierarchical structure that is so important in these systems. This helps to validate the mainframe datasets and ensure that the data is correctly migrated to the new system, which is critical for maintaining the integrity of the data and ensuring that it is properly understood by users.</p> </div>
