  The SAP error message RSMPC077, which states "No log exists for this update of PSA requests," typically occurs in the context of data extraction and loading processes in SAP BW (Business Warehouse). This error indicates that the system cannot find a log entry for the update of the Persistent Staging Area (PSA) requests, which can happen for several reasons.
  Causes:
  
  Missing Log Entries: The log for the specific update might not have been created or could have been deleted.
