DT186 - Details

• The SAP error message DT186 indicates that a generated proxy type cannot be used as an include. This typically occurs in the context of ABAP programming when you are trying to include a generated proxy type in a structure or another type definition, which is not allowed.
  
  Cause:
  
  Generated Proxy Types: The error arises because the proxy types generated by the SAP system (often from web services or other external interfaces) are not designed to be included in other types. They are standalone types that cannot be used as components of other structures or types.
  Type Compatibility: The generated proxy types may have specific characteristics or restrictions that prevent them from being included in other types, such as being defined as a reference type or having certain attributes that are incompatible with inclusion.
  
  
  Solution:
  
  Avoid Inclusion: Instead of trying to include the generated proxy type, you can use it directly in your code where needed.
