IT 0024 enhancement

Hello gurus,

ive searched various threads and postings in Google, marketplace, SCN, hoe to add custom columns into IT 0024.

But with no luck.

I managed to add columns in TC: PM01 in List screen. Im also able to see the fields in the screen layout when i select change.

But i didnt manage to show those added columns in TC PA30 when selecting IT 0024.

PS. ive read these posts:

2.Custom fields in IT0024

What could be the problem?

Best regards
