• What is the cause and solution for SAP error message RSM2177 - Standard DSO &1 contains only &2 requests with deleted changelog request ?

  The SAP error message RSM2177 indicates that a Standard DataStore Object (DSO) contains only a limited number of requests, specifically &2 requests, and that these requests have a deleted changelog request. This situation typically arises in the context of data warehousing and ETL processes within SAP BW (Business Warehouse).
  Cause:
  
  Deleted Changelog Request: The changelog for the DSO is essential for tracking changes to the data. If the changelog request has been deleted, it means that the system cannot find the necessary information to reconstruct the data state.
  Data Consistency Issues: The DSO may not have enough valid requests to provide a complete view of the data, leading to inconsistencies or incomplete data retrieval.
  Data Load Issues: If data loads were not successful or were interrupted, it could lead to situations where the DSO does not have the expected requests.
  
  Solution:
  
  Check the Changelog: Verify if the changelog request has indeed been deleted. If possible, restore the changelog or reprocess the data load to ensure that the changelog is populated correctly.
  Reprocess Data Loads: If the DSO is missing valid requests, consider reloading the data into the DSO. This may involve re-extracting data from the source system and ensuring that the data load process completes successfully.
  Data Consistency Check: Use transaction codes like RSA1 (Data Warehousing Workbench) to check the status of the DSO and ensure that it is consistent. You may need to perform a consistency check or repair the DSO.
  Delete and Reload: If the DSO is in a corrupted state and cannot be repaired, you may need to delete the existing requests and reload the data from the source system.
  Consult Documentation: Review SAP documentation or notes related to this error message for any specific recommendations or patches that may address the issue.
  
  Related Information:
