• What is the cause and solution for SAP error message SADL_GW_DT_CDS057 - Where-condition in consumption view can only have operator: &1. ?

  The SAP error message SADL_GW_DT_CDS057 typically occurs when there is an issue with the WHERE condition in a Core Data Services (CDS) view, particularly when using the SAP Gateway. This error indicates that the WHERE condition in the consumption view is using an operator that is not supported.
  Cause:
  The error message states that the WHERE condition can only have a specific operator (indicated by &1). This usually happens when:
  
  The CDS view is defined with a certain set of allowed operators, and the query being executed is trying to use an operator that is not permitted.
  The query might be using operators like IN, LIKE, or others that are not supported in the context of the CDS view.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Review the definition of the CDS view to understand which operators are allowed in the WHERE clause. You can do this by checking the annotations and the underlying data model.
  
  
  
  Modify the Query:
  
  If you are using an unsupported operator in your query, modify it to use one of the allowed operators. For example, if the error indicates that only = is allowed, ensure that your query uses equality checks instead of other operators.
  
  
  
  Use the Correct Syntax:
  
  Ensure that the syntax of your query is correct and adheres to the expected format for the CDS view.
  
  
  
  Check for Annotations:
  
  Sometimes, annotations in the CDS view can restrict the operators. Check for any annotations that might be limiting the operators available for use.
  
  
  
  Test with Different Conditions:
  
  If you are unsure which operators are supported, try testing the query with different conditions to identify which ones work without triggering the error.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific version you are using to get detailed information about the supported operators for CDS views.
