• What is the cause and solution for SAP error message WZ387 - Substitution for user & could not be entered ?

  SAP Error Message:
  
  WZ387 - Substitution for user & could not be entered
  
  Cause:
  This error occurs when the system is unable to create or enter a substitution rule for the specified user. Substitutions in SAP allow one user to act on behalf of another user, typically for workflow or approval processes. The error usually indicates one of the following issues:
  
  The substitution user ID entered does not exist or is invalid.
  The substitution period (start and end dates) is incorrect or overlaps with existing substitutions.
  The substitution rule is not properly maintained or activated.
  Missing or incorrect authorization for creating or maintaining substitutions.
  The substitution is being created in a client or environment where substitutions are not allowed or configured.
  
  
  Solution:
  To resolve the error WZ387, follow these steps:
  
  
  Verify User IDs:
  
  Check that the user ID for whom the substitution is being created exists and is active.
  Verify the substitute user ID is valid and active.
  
  
  
  Check Substitution Period:
  
  Ensure the start and end dates for the substitution are correct.
  Make sure the period does not overlap with any existing substitution entries for the same user.
  
  
  
  Maintain Substitution Properly:
  
  Use transaction SWDD (Workflow Builder) or SWI1 (Substitution Maintenance) to check and maintain substitution rules.
  Alternatively, use transaction SU01 to check user details and substitution settings.
  
  
  
  Check Authorizations:
  
  Ensure the user creating the substitution has the necessary authorizations (e.g., authorization object S_WF_SUBST).
  If authorization is missing, request the appropriate role or permission from your security team.
  
  
  
  Client and Environment Settings:
  
  Confirm that substitutions are allowed in the current client.
  Check system settings related to substitutions in workflow configuration.
  
  
  
  Recreate or Adjust Substitution:
  
  Delete any conflicting or incorrect substitution entries.
  Recreate the substitution with correct data.
