Hi,

try something like this:


DATA:
  ls_mara   TYPE mara,
  lv_str1   TYPE string VALUE 'LS_MARA',
  lv_str2   TYPE string VALUE 'MATNR',
  lv_field  TYPE string.

FIELD-SYMBOLS:
  <fs>  TYPE ANY.

CONCATENATE lv_str1 '-' lv_str2 INTO lv_field.
ASSIGN (lv_field) TO <fs>.

Best regards,

Oliver

Hi afromeen,

if I understand you correct, you want to substitute specific values in a table.

I would create a second table with same structure 3 columns: Structure, Field, Value. This table could be maintained using maintenance screen. Then put in here the Structure and Field names relevant for substitution and the substitution value.

Then loop at the original table. For each line, check if you have a substitution value. The substitution table can be loaded into a sorted or hashed key table and accessed quickly using READ TABLE WITH TABLE KEY. Use field-symbols to save time.
