SIG502 - Details

• The SAP error message SIG502 ("Signature order cannot be defined; identical individual signatures") typically occurs in the context of electronic signatures in SAP systems, particularly when dealing with workflows or document approvals that require multiple signatures.
  
  Cause:
  The error arises when the system detects that there are multiple signatures defined for a particular process or document, and these signatures are identical in terms of their configuration. This creates ambiguity in the signature order, as the system cannot determine which signature should be processed first.
  
  Solution:
  To resolve the SIG502 error, you can take the following steps:

  Check for any duplicate signature definitions that may have the same attributes (e.g., same user, same role, same conditions).
  
  
  
  Modify Signature Definitions:
  
  If you find identical signatures, modify them to ensure that each signature is unique. This could involve changing the user, role,
