  The SAP error message CL_SADL_GW_MDE_MSG040 typically indicates an issue related to the SAP Gateway and the Model Driven Entity (MDE) framework. This error can occur when there is a problem with the data being processed or when the expected data structure is not met.
  Cause:
  
  Empty Data Set: The error message suggests that the data set being processed is empty. This can happen if the query does not return any results or if there is a filtering condition that results in no data being fetched.
  Model Configuration Issues: There may be issues with the configuration of the OData service or the underlying data model.
  Authorization Issues: The user may not have the necessary authorizations to access the data, leading to an empty result set.
  Data Source Issues: The underlying data source (like a database table or view) may not contain any data or may be incorrectly configured.
  
  Solution:
  
  Check Data Availability: Verify that the data you are trying to access actually exists in the database. You can do this by running a direct query on the database table or view.

  Authorization Check: Ensure that the user has the necessary authorizations to access the data. You can check this in the user roles and authorizations assigned to the user.
  Debugging: If you have access to the backend, you can debug the OData service to see where the data retrieval is failing. This can provide insights into whether the issue is with the data model, the query, or the data source.
