• What is the cause and solution for SAP error message RS_SMA790 - The changelog table &1 has not as many partitions as the active table &2. ?

  The SAP error message RS_SMA790 indicates a mismatch in the number of partitions between the changelog table and the active table in the context of SAP BW (Business Warehouse) or SAP HANA. This typically occurs when there are discrepancies in the partitioning of these tables, which can lead to issues in data processing and reporting.
  Cause:
  
  
  Partitioning Mismatch: The changelog table (which stores changes to the data) does not have the same number of partitions as the active table (which holds the current data). This can happen due to various reasons, such as:
  
  Manual changes to the partitioning settings.
  Data load processes that did not complete successfully.
  Changes in the data model that were not properly reflected in the changelog table.
  
  
  
  Data Load Issues: If there were issues during data loading (e.g., failures, interruptions), it might lead to inconsistencies between the changelog and active tables.
  
  
  System Upgrades or Changes: Upgrading the system or making changes to the data model can sometimes lead to partitioning issues if not handled correctly.
  
  
  Solution:
  To resolve the RS_SMA790 error, you can follow these steps:
  
  
  Check Partitioning Settings:
  
  Verify the partitioning settings for both the changelog and active tables. Ensure that they are configured to have the same number of partitions.
  
  
  
  Recreate Changelog Table:
  
  If the changelog table is significantly out of sync, you may need to recreate it. This can often be done through the Data Warehousing Workbench or by using specific transaction codes (like RSA1).
  
  
  
  Repair the Data Model:
  
  If the issue is due to a change in the data model, you may need to repair or adjust the data model to ensure that both tables are aligned.
  
  
  
  Data Load Process:
  
  Rerun the data load process to ensure that all data is correctly loaded and that the changelog table is updated accordingly.
  
  
  
  Check for Errors in Data Load:
  
  Review the logs for any errors during the data load process that might have caused the inconsistency.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional guidance.
