3400672 - How to prevent approved Single Record Approval record from being edited or deleted

There is business requirement to prevent any change or deletion on an already approved single record approval recording. 
This KBA explains how it can be done and what the current limitation is.

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

• Scenario 1: The Time Sheet is in To Be Submitted status
  • Prevent change on approved SRA recording
    This can be achieved via a save rule like below in Employee Time Sheet Entry object definition
    
    This rule prevents any change on any approved single record approval. You can further adjust the rule based on your business requirement.
  • Prevent deletion on approved SRA recording
    This can be achieved by a delete rule like below in Employee Time Sheet Entry object definition
    
    
    This rule prevents deletion on any approved single record approval. You can further adjust the rule based on your business requirement.
• Scenario 2: The Time Sheet is in To be Approved status
  • When the time sheet is submitted and pending approval, the time sheet itself is not in editable mode. You will have to withdraw the time sheet to make any change. And once the To be Approved is withdrawn, it becomes To be Submitted status.
    So by default, there is no option to delete or change an approved single record approval record in a To be Approved time sheet. 
• Scenario 3: The Time Sheet is in Approved status
  • There is known limitation that currently it is not possible to prevent change or deletion of SRA record on an approved time sheet. 
    As possible workaround, you can consider using Time Recording Admissibility to prevent amendment on approved time sheet.
