• What is the cause and solution for SAP error message SADL_GW_DT_CDS086 - &1: Element &2 is typed incorrectly for this annotation ?

  The SAP error message SADL_GW_DT_CDS086 typically indicates that there is a type mismatch in the annotations of a Core Data Services (CDS) view or entity. This error often arises when the data type of an element does not match the expected type defined in the annotation.
  Cause:
  
  
  Type Mismatch: The element specified in the error message (&2) is defined with a data type that does not align with what is expected by the annotation. This could be due to:
  
  Incorrectly defined data types in the CDS view.
  Annotations that expect a specific type (e.g., string, integer, date) but are receiving a different type.
  Changes in the underlying data model that have not been reflected in the CDS definition.
  
  
  
  Annotation Misconfiguration: The annotation itself may be incorrectly configured, leading to the system expecting a different type than what is provided.
  
  
  Solution:
  
  
  Check the CDS View Definition:
  
  Review the definition of the CDS view where the error occurs. Ensure that the data types of the elements match the expected types defined in the annotations.
  Pay special attention to the annotations that are applied to the elements, as they dictate the expected data types.
  
  
  
  Correct the Data Types:
  
  If you find a mismatch, adjust the data type of the element in the CDS view to match the expected type in the annotation.
  If the annotation is incorrect, modify it to reflect the correct expected type.
  
  
  
  Re-activate the CDS View:
  
  After making changes, re-activate the CDS view to ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  If the CDS view is used in other objects (like OData services), ensure that those objects are also updated if necessary.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation for the specific annotations you are using to understand the expected data types and configurations.
