SAP ABAP Problems & Solution

 In our daily task like ALV report or in smartforms we need to change the sign position. In that case we need to use FM. I am sharing with you that FM with example.   FM: CLOI_PUT_SIGN_IN_FRONT   Before: WA_FINAL2 - DEVIATION = 4.08-              CALL  FUNCTION  'CLOI_PUT_SIGN_IN_FRONT'          CHANGING            VALUE          =  WA_FINAL2 - DEVIATION                  .   After: WA_FINAL2 - DEVIATION = -4.08
