어떻게 늘려 줄 수가 있나요?

 With ABAP/4 Open SQL SELECT, the output area is too small.

 In this particular case, the database table is 52 bytes wide,
 but the output area is only 40 bytes wide.

DATA: BEGIN OF itab,
a type /1FB/MD_________2S300H1,
b type /1FB/MD_________2S300GE,
END OF itab.

* 거래구분
      SELECT SINGLE * into itab
         FROM (l_tabname1) "/1FB/MD___2S00B5
       WHERE /1FB/CS_CHART = PS_PARAMETER-CS_CHART
         AND /1FB/CS_ITEM = GT_DATA-CS_ITEM.
