The SAP error message
/IWFND/CM_MGW087
typically indicates an issue with the metadata routing in the SAP Gateway framework, specifically related to the configuration of the IWF (Integrated Web Framework) customizing settings. This error often arises when the system is unable to determine the correct service or metadata based on the provided request, particularly when using Group-based Service Definition Objects (GSDO).Cause:
- Incorrect Configuration: The error may occur if the service is not properly configured in the SAP Gateway. This includes issues with the service registration or the service definition.
- Missing or Incorrect GSDO: If the Group-based Service Definition Object (GSDO) is missing or incorrectly defined, the system may not be able to route the request correctly.
- Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the service, leading to routing failures.
- Service Activation: The service might not be activated in the SAP Gateway, which can prevent proper routing.
- Metadata Issues: Problems with the metadata itself, such as missing or incorrect entity sets, can also lead to this error.

- Ensure that the user has the necessary authorizations to access the service. This can be done by checking the roles assigned to the user.
Activate Services:
- If the service is not activated, activate it using the Service Maintenance transaction.
Review Metadata:

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
