Hi @rendywinata_,

You can define the return-value from the function as a OUT-parameter in the source column section.

Please refer the following.

Calling Functions from Method List

We may now also invoke functions from the Method List. They will be handled in Method List Attributes in the same manner as procedures.

1. The return-value from the function is defined as OUT-parameter FUNCTION_RESULT.
2.  The IN-parameter is defined in same manner as parameters for procedures.
   
   
3.  The result of the function may be used in following methods.
