Answer 1

There is a workaround for substittuting the WTAX code, that could also work for tax amount.
if in your substitution form (Uxxx) you import the WITH_ITEM table you can modify the records.
  table = '(SAPLFWTG)X_WITH_ITEM[]'.
  ASSIGN (table) TO <fs_with_item>.
  IF sy-subrc = 0.
             LOOP AT <fs_with_item> ASSIGNING <fs_line>.
            IF sy-subrc = 0.
              ASSIGN COMPONENT 'WT_WITHCD'
                OF STRUCTURE <fs_line>
                TO <fs_field>.
              IF sy-subrc = 0.
                <fs_field> = l_wtaxcode. "your tax code
              ENDIF.
              UNASSIGN <fs_field>.
            ENDIF.
            UNASSIGN <fs_line>.
          ENDLOOP.
        ENDIF.
      ENDIF.
    ENDLOOP.
  ENDIF.
  UNASSIGN <fs_with_item>.
