  The SAP error message /MERP/CORE_OMDO007 Unsupported oData method &1 for entity &2 typically indicates that an OData service is being called with an HTTP method that is not supported for the specified entity. This can occur in various scenarios when working with SAP Gateway and OData services.
  Cause:
  
  Unsupported HTTP Method: The error is triggered when an OData request is made using an HTTP method (like POST, PUT, DELETE, etc.) that is not implemented for the specified entity.

  Solution:
  
  
  Check the OData Service Implementation:
  
  Review the OData service implementation in the SAP Gateway Service Builder (transaction code SEGW).
