• What is the cause and solution for SAP error message SIG513 - No signature sequence found: identical individual signatures ?

  The SAP error message SIG513 ("No signature sequence found: identical individual signatures") typically occurs in the context of electronic signatures in SAP systems, particularly when dealing with document approvals or workflows that require digital signatures. This error indicates that the system has detected that the individual signatures being processed are identical, which means that it cannot determine a valid sequence for the signatures.
  Cause:
  
  Identical Signatures: The most common cause of this error is that the same user or signature is being applied multiple times in a sequence where unique signatures are expected.
  Configuration Issues: There may be issues with the configuration of the signature process in the SAP system, leading to the system not recognizing the sequence of signatures correctly.
  Workflow Design: The workflow may be designed in such a way that it does not allow for the proper sequencing of signatures, especially if the same individual is required to sign multiple times.
  
  Solution:
  
  Check Signature Configuration: Review the configuration settings for electronic signatures in the SAP system. Ensure that the settings allow for unique signatures in the required sequence.
  Modify Workflow: If the workflow is designed to require multiple signatures from the same individual, consider modifying it to allow for different individuals to sign or to change the sequence of signatures.
  Use Unique Signatures: Ensure that different users are assigned to sign the document or that the same user does not sign multiple times in a row without a different signature in between.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring electronic signatures and workflows.
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance, as they may provide insights specific to your system configuration or version.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide updates and patches that could resolve the issue.
  Transaction Codes: Familiarize yourself with transaction codes related to electronic signatures and workflow management, such as SWDD (Workflow Builder) or SICF (HTTP Service Hierarchy Maintenance).
  User Roles and Authorizations: Ensure that the users involved in the signature process have the appropriate roles and authorizations to perform their tasks.
  
  By addressing the causes and implementing the suggested solutions, you should be able to resolve the SIG513 error in your SAP system.
