Coding block new field additon

Hi Folks,

I already have 4 fields added to my coding block screen in SAPLKACB 9999, Iam unable to add one more field to the screen. I followed the below steps.

1. Added the new field to CI_COBL part of COBL structure.

2. Added code to the user exits ACCOBL01.

Not sure what Iam doing wrong here. Please let me know If you came across this scenario before.

Thanks,

Ramki
