• What is the cause and solution for SAP error message RSRV186 - PSA Table &1 is not partitioned (according to RSTSODS) ?

  The SAP error message RSRV186 indicates that a Persistent Staging Area (PSA) table is not partitioned according to the RSTSODS (DataSource) settings. This can occur in the context of SAP BW (Business Warehouse) when data is being loaded into the PSA, and the system expects the PSA table to be partitioned for performance and management reasons.
  Cause:
  
  Missing Partitioning: The PSA table is not set up to be partitioned, which can lead to performance issues when handling large volumes of data.
  Configuration Issues: The DataSource configuration may require partitioning, but the PSA table was created without this setting.
  Inconsistent Settings: There may be inconsistencies between the DataSource settings and the actual PSA table configuration.
  
  Solution:
  To resolve the RSRV186 error, you can follow these steps:
  
  
  Check DataSource Settings:
  
  Go to the DataSource in the SAP BW system and check the settings related to partitioning. Ensure that the DataSource is configured to use partitioning.
  
  
  
  Modify PSA Table:
  
  If the PSA table is not partitioned, you may need to modify it. You can do this by:
  
  Using transaction code RSA1 to access the Data Warehousing Workbench.
  Navigate to the PSA and check the properties.
  If necessary, create a new PSA table with the correct partitioning settings.
  
  
  
  
  
  Use Transaction RSRV:
  
  Execute transaction RSRV to run the consistency check for the PSA. This will help identify any other issues related to the PSA table.
  You can also use RSRV to check the specific error and see if there are any additional recommendations.
  
  
  
  Recreate the PSA:
  
  If the above steps do not resolve the issue, consider deleting the existing PSA table and recreating it with the correct partitioning settings.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to PSA and partitioning for any specific guidelines or updates that may apply to your version of SAP BW.
