Iprocurement - urgent question - on content zones and extensions on it

 hello

at the customer site they are using R11i and doing an upgrade from 11.5.10 to R12
in that release they use Iprocurement but have customized the realm functionality to point at a different category for realms
- so basically the item has a purchasing category and has a realm category assigned on the item master (so a new category linked to the item) (as the customer did not want to use the purchasing categories and the iproc categories)

Eg item helmet  (R11i)

Assigned in item master to:

Realm category – logistics.xx.xx

Purchasing category – helmets.bycicles.purchase

then the realms are defined  in the realm screen
