  Modify Selection Criteria: If you are using a selection screen or a report that allows for wildcard entries, ensure that you are using specific product identifiers instead of wildcards.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the correct usage of product allocations and any restrictions regarding wildcards.
  Error Handling: If the error persists, consider implementing error handling in your process to catch and manage such issues more gracefully.
