I experience a confusing issue with built-in SAP transformation ID
.
I try to serialize ABAP structure, but result XML is always empty. Do you have any suggestions, what is wrong with my code?
DATA lv_xml TYPE xstring.
CALL TRANSFORMATION ID
SOURCE test = syst
RESULT XML = lv_xml.
IF lv_xml IS INITIAL.
MESSAGE `Oops, it's empty!` TYPE 'S' DISPLAY LIKE 'W'.
ELSE.
CALL FUNCTION 'DISPLAY_XML_STRING'
EXPORTING
xml_string = lv_xml.
ENDIF.
Almost correct:
CALL TRANSFORMATION ID
SOURCE test = syst
RESULT XML lv_xml. " no = here!
The other syntax is correct as well, it just does something completely different: it searches for an element named XML
and assigns the value of that element to lv_xml
. Since there's no XML
element, the string stays empty.
