structure that does not depict a generated proxy type or in a database
table.
The usage of such structures as an inlucde should only be possible,
however, if the user is a generated proxy type.
Generated proxy types can be data elements, structures, and table
types.

• What is the cause and solution for SAP error message DT186 - & is a generated proxy type, cannot be used as include ?

  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. For example, if you need to use the proxy type in a method or function, declare a variable of that proxy type instead of trying to include it in a structure.
  Create Wrapper Types: If you need to group multiple types together, consider creating a new structure or type that contains fields of the proxy type as references or separate variables, rather than trying to include the proxy type itself.
  Check Proxy Definition: Review the definition of the proxy type to ensure that it is being used correctly. Sometimes, the way the proxy is generated or defined can lead to misunderstandings about its usage.
  
  Related Information:
  
  Proxy Generation: Proxy types are typically generated when you create a web service or when you consume an external service. They are defined in the context of the service interface and may have specific attributes that dictate how they can be used.
  ABAP Documentation: Refer to the SAP ABAP documentation for more details on type definitions, structures, and the limitations of generated proxy types.
  SAP Community: If you continue to face issues, consider reaching out to the SAP Community or forums where other developers may have encountered similar issues and can provide insights or workarounds.
  
  By following these guidelines, you should be able to resolve the DT186 error and effectively work with generated proxy types in your ABAP programs.
