  Review Rule Definitions: Go through the rules associated with the event in question. Ensure that there are no conflicting rules and that each rule has a clear precedence. Look for circular dependencies and resolve them.
  Reorganize Rules: If necessary, reorganize the rules to ensure that they can be processed in a topological order. This may involve breaking down complex rules into simpler ones or redefining the logic.
  Testing: After making changes, thoroughly test the rules to ensure that the ambiguity has been resolved and that the system behaves as expected.
  Consult Documentation: Refer to SAP documentation or guidelines for defining rules in the specific module you are working with. This can provide insights into best practices and common pitfalls.
