The ref. node has either not been defined or does not have the required type?.

Hi experts. I am newbie using Abap. I want to convert data from internal table to XML format using structure, but I am facing this issue and I dont know to solve this:

Simple Transformation:

I am using functions to do the process..

I have moved the data from internal tables to the structure what I declared in the Export Tab of the function,

and I am trying to pass the same structure to the simple transformation. (this structure has already all moved data)

DATA : xml_result TYPE xstring.  

CALL TRANSFORMATION ZPRUEBA2
    SOURCE root = cartaporte
  RESULT XML  xml_result  .

What is the ABAP code and the types of variables you pass to the root? (structure/internal table)

(no need to post a screenshot; paste the code and format it by pressing the button CODE)

Thank you.

Your unique root is named 'cartaporte' (<tt:root name='cartaporte') so you should indicate its name in CALL TRANSFORMATION:

CALL TRANSFORMATION ZPRUEBA2
    SOURCE cartaporte = cartaporte
  RESULT XML  xml_result  .

Based on your transformation, it requires that the variable 'cartaporte' (right-hand side) is a structure of type ZCPXML_CARTAPORTE.

Thank yo so much. It works. I corrected the name 'root' to 'cartaporte' and now its working.:))
