  The SAP error message /IWNGW/CM_BEP_RT008 Not all inputs are valid typically occurs in the context of SAP Gateway or SAP Fiori applications when there are issues with the input parameters being sent to a backend service. This error indicates that one or more of the inputs provided to the service are not valid, which can prevent the service from processing the request successfully.
  Causes:

  Data Type Mismatch: The input parameters may not match the expected data types defined in the OData service.

  Review Business Logic: Check if there are any specific business rules or validations implemented in the backend that might be causing the input to be rejected.
  Check Authorizations: Ensure that the user has the necessary authorizations to execute the operation. If not, appropriate roles and permissions should be assigned.
