• What is the cause and solution for SAP error message SADL_GW_DT_CDS005 - Do not use the element &1 in the association definition. ?

  The SAP error message SADL_GW_DT_CDS005 indicates that there is an issue with the definition of an association in a Core Data Services (CDS) view. Specifically, the error states: "Do not use the element &1 in the association definition." This typically occurs when an element (field) that is being referenced in the association definition is not allowed or is not suitable for that context.
  Cause
  The error can be caused by several factors:
  
  Invalid Field Reference: The field being referenced in the association may not be a valid key or may not exist in the context of the CDS view.
  Association Context: The field may not be appropriate for use in an association, such as being a non-key field or a field that does not have a direct relationship with the target entity.
  Data Model Issues: There may be issues with the underlying data model, such as missing relationships or incorrect cardinality definitions.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Field Validity: Ensure that the field referenced in the association is valid and exists in the data model. Verify that it is a key field or a field that can be used in the association.
  
  
  Review Association Definition: Look at the association definition in your CDS view. Make sure that you are using the correct syntax and that the fields being referenced are appropriate for the association.
  
  
  Use Key Fields: If you are trying to create an association, ensure that you are using key fields from both the source and target entities. Associations typically require key fields to establish a relationship.
  
  
  Consult Documentation: Refer to the SAP documentation for Core Data Services and associations to understand the requirements and limitations for defining associations.
  
  
  Test with Simplified Model: If the issue persists, try simplifying the model by removing complex associations or fields to isolate the problem.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as there may be patches or updates that address known issues with CDS views.
