• What is the cause and solution for SAP error message SADL_GW_DT_CDS048 - Foreign key association &1 is not found. Check the association alias. ?

  The SAP error message SADL_GW_DT_CDS048 indicates that there is an issue with a foreign key association in a Core Data Services (CDS) view or a related data model. Specifically, it means that the system cannot find the specified foreign key association, which is identified by the alias &1. This can occur in various scenarios, such as when you are trying to access data through an OData service or when working with CDS views in ABAP.
  Causes
  
  Incorrect Association Alias: The alias used in the CDS view or OData service does not match any defined association in the data model.
  Missing Association: The association that is being referenced may not be defined in the CDS view or may have been deleted or renamed.
  Modeling Errors: There may be errors in the way the CDS view is modeled, such as incorrect syntax or missing elements.
  Transport Issues: If the CDS view was transported from one system to another, there may be inconsistencies in the data model.
  Activation Issues: The CDS view or its dependencies may not be activated properly.
  
  Solutions
  
  
  Check the Association Definition: Verify that the association is correctly defined in the CDS view. Ensure that the alias used in the query matches the defined association.
  
  Example: If your CDS view has an association defined as association to AnotherEntity as AnotherEntityAlias, ensure you are using AnotherEntityAlias in your query.
  
  
  
  Review the CDS View: Open the CDS view in the ABAP Development Tools (ADT) or SE11 transaction and check for any syntax errors or issues in the definition.
  
  
  Activate the CDS View: If the CDS view or its dependencies are not activated, activate them. You can do this in the ADT or using transaction SE11.
  
  
  Check for Transport Issues: If the CDS view was recently transported, ensure that all related objects (like tables, other views, etc.) are also transported and activated in the target system.
  
  
  Debugging: If you are using the OData service, you can use transaction /IWFND/ERROR_LOG to check for any additional error messages that might provide more context.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for any known issues related to the specific version of SAP you are using.
