CONCATENATE LINES OF itbl
If you want to serialize a set of strings stored in an internal table there are two ways to do it. One is dull, the other one is full of style.
Let’s start by defining our data:
TYPES: BEGIN OF ty_output, field1 TYPE char10, field2 TYPE char10, field3 TYPE char10, END OF ty_output. DATA: t_output TYPE TABLE OF ty_output. APPEND INITIAL LINE TO t_output ASSIGNING <output> . <output>- field1 = 'a1' . <output>- field2 = 'a2' . <output>- field3 = 'a3' . APPEND INITIAL LINE TO t_output ASSIGNING <output> . <output>- field1 = 'b1' . <output>- field2 = 'b2' . <output>- field3 = 'b3' .
We now have an internal table with a 3 field structure filled with 2 records.
Our goal: to serialize everything into a single line: a1 a2 a3 b1 b2 b3.
If you’re an old-fashioned dude who listens to crappy music, has no taste in dressing and likes to have dinner at Macdonalds you’ll do this:
LOOP AT t_output ASSIGNING <output>. CONCATENATE opcao1 <output>-field1 <output>-field2 <output>-field3 INTO opcao1 SEPARATED BY space . ENDLOOP. CONDENSE opcao1.
If, instead, you’re a sophisticated person who only listens to really good music, likes fashionable clothes and refuses to eat any food without molecular in its name, then this is what you’ll do:
CONCATENATE LINES OF t_output INTO opcao2 SEPARATED BY space. CONDENSE opcao2.
