• What is the cause and solution for SAP error message IWB_MPS145 - Restrict the selection of objects to one ID ?

  The SAP error message IWB_MPS145 ("Restrict the selection of objects to one ID") typically occurs in the context of the SAP Gateway or OData services when a user attempts to perform an operation that requires a single object ID, but multiple IDs are provided instead. This can happen in various scenarios, such as when trying to update or delete a resource in an OData service.
  Cause:
  The error is caused by the following reasons:
  
  Multiple IDs Provided: The request sent to the OData service includes multiple object IDs when the operation only supports a single ID.
  Incorrect URL Format: The URL used in the request may not be correctly formatted to specify a single resource.
  Client-Side Logic: The client application (e.g., a UI5 application) may be incorrectly configured to send multiple IDs instead of a single one.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Request: Review the request being sent to the OData service. Ensure that it specifies only one object ID. For example, if you are trying to delete or update a record, the URL should look like this:
  /entitySet('singleID')
  Instead of:
  /entitySet('id1','id2')
  
  
  Modify Client Logic: If you are using a custom application (like SAPUI5), ensure that the logic that constructs the request is correctly set up to handle only one ID at a time.
  
  
  Debugging: Use debugging tools or logs to trace the request being sent. This can help identify where multiple IDs are being introduced.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using to understand the expected request format and constraints.
  
  
  Error Handling: Implement error handling in your application to catch this error and provide user-friendly feedback or corrective actions.
