• What is the cause and solution for SAP error message RSDU_REPART025 - Partitioning key is not part of technical key ?

  The SAP error message RSDU_REPART025 indicates that there is an issue with the partitioning key in a DataStore Object (DSO) or InfoCube. Specifically, it means that the partitioning key you are trying to use is not part of the technical key of the DSO or InfoCube. This can occur during data loading or when trying to activate a DSO.
  Cause:
  
  Mismatch in Keys: The partitioning key you are trying to use does not match the technical key defined in the DSO or InfoCube. The technical key is a combination of fields that uniquely identifies a record in the DSO or InfoCube.
  Incorrect Configuration: The configuration of the DSO or InfoCube may not have been set up correctly, leading to a situation where the partitioning key is not aligned with the technical key.
  Changes in Data Model: If there have been recent changes to the data model (like adding or removing fields), it may have affected the relationship between the partitioning key and the technical key.
  
  Solution:
  
  
  Check Technical Key: Verify the technical key of the DSO or InfoCube. Ensure that the fields you are using as the partitioning key are included in the technical key.
  
  Go to the Data Warehousing Workbench (transaction RSA1) and check the structure of the DSO or InfoCube.
  
  
  
  Adjust Partitioning Key: If the partitioning key is incorrect, you may need to adjust it to ensure it includes only those fields that are part of the technical key.
  
  Modify the partitioning key settings in the DSO or InfoCube configuration.
  
  
  
  Recreate the DSO/InfoCube: If the issue persists and cannot be resolved through configuration changes, consider recreating the DSO or InfoCube with the correct settings.
  
  
  Data Load Process: Review the data load process to ensure that the data being loaded adheres to the structure defined in the DSO or InfoCube.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using for any additional guidance or known issues.
  
  
  Related Information:
  
  Technical Key: The technical key is a set of fields that uniquely identifies a record in a DSO or InfoCube. It is crucial for data integrity and proper data loading.
  Partitioning Key: This is used to divide data into manageable segments for performance optimization. It should always align with the technical key.
  SAP Notes: Check SAP Notes for any updates or patches that may address this issue. You can search for relevant notes in the SAP Support Portal.
  
  By following these steps, you should be able to resolve the RSDU_REPART025 error and ensure that your DSO or InfoCube is correctly configured for data loading and processing.
