• What is the cause and solution for SAP error message RSDU_REPART012 - New partitioning schema is identical to old schema ?

  The SAP error message RSDU_REPART012 indicates that there is an attempt to create a new partitioning schema for a DataStore Object (DSO) or InfoCube that is identical to the existing partitioning schema. This typically occurs during the process of re-partitioning a data model in SAP BW (Business Warehouse).
  Cause:
  The error arises when the system detects that the new partitioning schema you are trying to define does not differ from the existing one. This can happen if:
  
  You mistakenly attempt to apply the same partitioning settings that are already in place.
  There is a misunderstanding of the partitioning requirements, leading to an unnecessary redefinition of the schema.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Verify Existing Partitioning Schema:
  
  Check the current partitioning schema of the DSO or InfoCube to confirm its settings. You can do this in the Data Warehousing Workbench (transaction RSA1) or by using the relevant data model transaction.
  
  
  
  Modify the New Schema:
  
  If you intended to change the partitioning schema, ensure that the new schema has at least one difference compared to the existing one. This could involve changing the partitioning criteria, adding or removing partitions, or modifying the partitioning strategy.
  
  
  
  Delete Unnecessary Changes:
  
  If you are trying to apply changes that are not needed, simply cancel the operation or revert to the original settings.
  
  
  
  Check for System Notes:
  
  Sometimes, SAP releases notes or updates that may address specific issues related to partitioning. Check the SAP Support Portal for any relevant notes that might provide additional guidance or fixes.
  
  
  
  Consult Documentation:
  
  Review the SAP BW documentation for best practices on partitioning and re-partitioning to ensure you are following the correct procedures.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the changes in a development or test environment before applying them to production.
