Field symbol with component "MARA-MTART"

[AJeB]

Hi experts,

I have a field symbol like this 

MARA-MATNR	MARA-MTART	MARA-MAKTL
1	test_mtart1	test_matkl1
2	test_mtart2	test_matkl2
3	test_mtart3	test_matkl3

and I want to change the MARA-MTART values but the problem is I can't pass the value from variable to the internal table, after <fs_mtart>- , I can't put the mara-mtart .

how can I pass the value if the component of itab is something like this -> MARA-MTART ?

My sample code

FIELD-SYMBOLS: <ft_mtart> TYPE table, "this is a standard declaration
               <fs_mtart> TYPE any. "this is a standard declaration

DATA: lv_mtart TYPE mara-mtart.

"lets say the mtart is always 5
lv_mtart = '5'.

ASSIGN (lv_mtart) TO <fs_mtart>-mara-mtart. "not working
<fs_mtart>-mara-mtart = lv_mtart "not working

"I tried to create an internal table but not working
TYPES: begin of ts_mtart,
      mtart TYPE mara-mtart,
       end of ts_mtart.
DATA: ls_mtart TYPE ts_mtart
ASSIGN COMPONENT sy-index OF STRUCTURE ls_mtart TO <fs_mtart>-mara-mtart.

FIELD-SYMBOLS: <fs_mara> TYPE mara.
DATA: l_mtart TYPE mara-mtart.

l_mtart = '5'.

<fs_mara>-mtart = l_mtart.

" ¯\_(ツ)_/¯

[AJeB]

<fs_mara>-mtart = l_mtart. will not work because the component is "MARA-MTART", If the component is "MTART" only your solution will work

[vulturas4]

data lt_mara type table of mara.

lt_mara = value #( ( mtart = '5' ) ).

assign lt_mara[ mtart = '5' ] to field-symbol(<fs_mara>).
cl_demo_output=>display( <fs_mara>-mtart ).

Improved 🙂 Will that help?
