• What is the cause and solution for SAP error message SADL_GW036 - Message target paths are not supported for higher expand levels ?

  The SAP error message SADL_GW036 indicates that there is an issue with the way you are trying to expand data in a service that uses the SAP ABAP Programming Model for SAP Fiori. Specifically, this error occurs when you attempt to use higher expand levels in your OData service that are not supported for the target paths you are trying to access.
  Cause:
  The error is typically caused by one of the following reasons:
  
  Unsupported Expand Levels: The OData service you are using does not support the level of expansion you are trying to perform. This can happen if you are trying to expand too many related entities at once or if the relationships between entities are not defined correctly.
  Complexity of Relationships: The relationships between the entities may be too complex for the service to handle, especially if there are circular references or deep hierarchies.
  Service Configuration: The OData service may not be configured to allow for the specific expand paths you are trying to use.
  
  Solution:
  To resolve the SADL_GW036 error, you can try the following solutions:
  
  
  Reduce Expand Levels: Simplify your OData query by reducing the number of expand levels. Instead of trying to expand multiple related entities at once, consider fetching them in separate requests.
  
  
  Check Entity Relationships: Review the relationships defined in your data model. Ensure that the associations between entities are correctly defined and that there are no circular references.
  
  
  Service Configuration: Check the configuration of your OData service. Make sure that the service is set up to handle the expand paths you are trying to use. You may need to adjust the service definition or the underlying data model.
  
  
  Use Navigation Properties: Instead of using expand, consider using navigation properties to access related entities. This can sometimes help avoid the limitations of expand levels.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using. There may be specific guidelines or limitations regarding expand levels and paths.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see how it processes the request and identify where it fails.
  
  
  Related Information:

  By following these steps, you should be able to identify the cause of the SADL_GW036 error and implement a solution to resolve it.
