Dynamic element specification in call transformation

[former_member311422]

Hello, I'm using call transformation to convert xml to abap structure.

call transformation demo_id_upper_lower "id 
parameters mode = 'UP' 
source xml asxml_str 
result paymentrequest = abap_out. 

This works as expected and the data is mapped to abap structure successfully. 'paymentrequest' being the root tag here. Is there a way to specify a variable containing the tag name instead of the tag directly in the result.

Eg. data(my_var) = 'paymentrequest'. 

call transformation demo_id_upper_lower "id 
parameters mode = 'UP' 
source xml asxml_str 
result my_var = abap_out. 

In this case there's no exception as such but then there's no conversion(I think it tries to find 'my_var'). I'm trying to encapsulate the conversion in a method/fm, hence the requirement.

Note: I have also tried assigning the element name to a field symbol. But that too didn't work.

Lets try this:

DATA MAPP TYPE ABAP_TRANS_RESBIND_TAB.

MAPP = VALUE #( ( NAME = 'PAYMENTREQUEST' VALUE = REF #( abap_out ) ) ).

CALL TRANSFORMATION ID SOURCE XML l_xml
 RESULT (MAPP) .

Excellent. Thanks a lot. Exactly what I was looking for.

data(result_tab) = value abap_trans_resbind_tab( ( name = root value = ref #( abap_out ) ) ).

        call transformation demo_id_upper_lower "id
        parameters mode = 'UP'
        source xml asxml_str
        result (result_tab).

        if result_tab is not initial.
          read table result_tab into data(result_wa) index 1.
          if sy-subrc = 0.
            assign result_wa-value->* to field-symbol(<abap_out>).
            if <abap_out> is assigned.
              abap_out = <abap_out>.
            endif.
          endif.
        endif.
