Data Validation in SAP S/4HANA Group Reporting

Data Validation in SAP S/4HANA Group Reporting

The sources explain that data validation in SAP S/4HANA Group Reporting is an essential process for ensuring data accuracy and consistency. The sources focus on data validation within the "Validation" section, which addresses common challenges and issues users might encounter when working with validation apps or tasks in the system.

Validation Rules and Methods

Validation rules are the criteria used to check the data, while validation methods are collections of rules that are applied together. The sources highlight the importance of activating predefined or imported validation rules and methods for them to function correctly. This can be done through the Import/Export Validation Settings app (or Import and Export Validation Rules and Methods app or transaction code VECIE for releases prior to S/4HANA 1909 FPS00).

Common Issues

• Incomplete amount calculation: For releases prior to S/4HANA OP 1909 FPS00, ensure that the ALPHA conversion routine is considered for relevant fields when defining validation rules, especially when dealing with numeric and alphanumeric values. The ALPHA conversion routine handles leading zeroes and wildcard characters to ensure that all relevant values are included in the calculation.
• System dump error after upgrade: After upgrading to S/4HANA 2020 FPS01, users might encounter system dump errors when running validation tasks. This is due to the introduction of multiple group-by fields in validation rules, which causes incompatibility. To resolve this, activate all existing validation rules using the Schedule Mass Activation Jobs - Rules, Methods, and Selections app.
• System dump error during execution: System dump errors during validation task execution can also occur due to changes in the configuration content. To address this, activate the relevant validation method using the Schedule Mass Activation Jobs - Rules, Methods, and Selections app, creating an immediate job run for activation.

Optimizing Validation Performance

The sources provide some tips on how to optimize system performance, especially when dealing with a large number of validation rules:

• Minimize rules and operands: Keep the number of rules in each method and operands in each rule to a minimum.
• Simplify filter conditions: Use direct input values in filter conditions instead of field attributes and hierarchies, as the latter consumes more memory.
• Use "group-by" fields: When similar rules apply to the same dimension, consider using "group-by" fields in the rule definition to reduce redundancy.
• Implement note 3082123: Apply SAP Note 3082123 to support up to 3000 validation rules in one method, thus improving system performance. However, note that even with this note, processing a large volume of data with many validation rules can still lead to memory issues.

The sources emphasize the need to carefully design and implement validation rules and methods to ensure data quality and maintain optimal system performance in SAP S/4HANA Group Reporting.
