• What is the cause and solution for SAP error message DDLS440 - No table function can be selected as proxy object ?

  The SAP error message DDLS440 ("No table function can be selected as proxy object") typically occurs when you are trying to create a proxy object for a table function in SAP, but the system does not allow it because table functions are not supported as proxy objects.
  Cause:
  
  Table Function Limitation: In SAP, table functions are designed to return a table-like structure but are not intended to be used as proxy objects. Proxy objects are typically used for remote function calls (RFC) or web services, and table functions do not fit this model.
  Incorrect Object Type: You may be trying to use a table function where a different type of object (like a standard function module or a method from a class) is expected.
  
  Solution:
  
  Use a Standard Function Module: If you need to expose functionality as a proxy, consider creating a standard function module that wraps the logic of the table function. This function module can then be used as a proxy object.
  Create a Wrapper: If the table function is essential for your logic, create a wrapper function module that calls the table function internally and returns the results in a suitable format.
  Check Object Type: Ensure that you are selecting the correct type of object when creating a proxy. Only function modules or methods that are designed for remote calls can be used as proxies.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal for detailed information on creating proxy objects and the limitations of different object types.
  ABAP Development: Familiarize yourself with ABAP development practices, especially regarding function modules and their usage in remote calls.
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or updates regarding this error message.
  
  By following these steps, you should be able to resolve the DDLS440 error and successfully create the necessary proxy object for your application.
