I have enhanced the Iw32 screen with input value.
I have appended the AUFK & CAUFVD Strucuture with ZZVALUE.
user exits am using : EXIT_SAPLCOIH_018, EXIT_SAPLCOIH_019.
screen no. SAPLCOIH - 0900.
When i try to save it from IW32 Transaction and value (caufvd-zzvalue or aufk-zzvalue )is not being update on table AUFK neither On the screen.
