EWA073 - Details

• The SAP error message EWA073 indicates that there is a mismatch between the key date for an installation and the key date of the service frequency. This typically occurs in the context of service management or maintenance planning within SAP, where the system expects the key date for an installation to be on or after the key date of the service frequency.
  
  Cause:
  
  
  Key Date Mismatch: The key date for the installation (e.g., the date when the installation was created or last updated) is set to a date that is earlier than the key date defined for the service frequency. This can happen if the installation was created or modified incorrectly or if the service frequency was updated after the installation date.
  
  
  
  Configuration Issues: There may be configuration issues in the service frequency settings or the installation data that lead to this inconsistency.
  
  
  
  Solution:
  
  
  Check Installation Key Date: Review the key date for the installation
