Re: Hiding sensitive EBS column data from certain users

Syed,

Your best bet is to use the security functionality of EBS to differentiate between groups of users, either by setting up custom responsibilities or even multi-org functionality.  EBS is extremely integrated with Oracle database, and as you know many features within Oracle database were instigated by EBS (i.e. VPD, editions, etc) over the years.

I'm sure something clever might be devised that might work in R12.2.6, but you'd have to add retesting of such functionality to already enormous project of patching and upgrading, forever.  And if any future patch or upgrade did break what was concocted, then it would be a lengthy task for future folks to determine if it can be fixed or to start from square one again.

In summary, this is actually a functional problem, not a technical problem.

Hope this helps...
