• SAP Error Message:
  WS304 No update time found for document &
  
  
  Cause:
  This error typically occurs during workflow processing or when trying to update or process a document in SAP. The system expects an "update time" (a timestamp indicating when the document was last updated) but cannot find it for the specified document.
  Common causes include:
  
  The document header or related tables do not have a valid timestamp or update time entry.
  The document might be incomplete or corrupted.
  The workflow or process is trying to access a document that has not been properly saved or committed.
  In some cases, this can happen if the document was deleted or archived but the workflow or process still references it.
  Custom code or enhancements that manipulate document data incorrectly.
  
  
  
  Solution:
  
  
  Check Document Existence and Status:
  
  Verify that the document number referenced in the error exists in the system.
  Check if the document is complete and properly saved.
  Use transaction codes like FB03 (for financial documents), ME23N
