• What is the cause and solution for SAP error message CL_SADL_GW_MDE_MSGX064 - Filter is wrongly defined ?

  The SAP error message CL_SADL_GW_MDE_MSGX064 indicates that there is an issue with the filter definition in a service that uses the SAP ABAP programming model for SAP Fiori applications. This error typically arises when the filter criteria specified in a query or service are not correctly defined or are incompatible with the underlying data model.
  Causes:
  
  Incorrect Filter Syntax: The filter may contain syntax errors or invalid expressions that cannot be processed.
  Unsupported Data Types: The filter might be using data types that are not supported by the service or the underlying data model.
  Missing Fields: The filter may reference fields that do not exist in the data model or are not included in the service definition.
  Logical Errors: The logical conditions used in the filter may not make sense or may conflict with the data model.
  Service Configuration Issues: There may be issues with the configuration of the OData service or the underlying CDS views.
  
  Solutions:
  
  Review Filter Definition: Check the filter criteria for any syntax errors or unsupported expressions. Ensure that the filter is correctly defined according to the OData standards.
  Validate Data Types: Ensure that the data types used in the filter match those defined in the data model. For example, if a field is defined as an integer, ensure that the filter does not use a string.
  Check Field Existence: Verify that all fields referenced in the filter are part of the data model and are included in the OData service.
  Test with Simplified Filters: Start with a simplified version of the filter to isolate the issue. Gradually add complexity to identify the specific part causing the error.
  Review Service Configuration: Check the configuration of the OData service and the underlying CDS views to ensure they are set up correctly.
