Required patches for R12 Collections

Hello,

We completed an upgrade from Oracle 11i to Oracle R12 last year and are now looking at setting up the Basic Collections module which since the upgrade has been integrated into AR.

The plan is to perform a basic setup of Collections so that an AR clerk can view the Collections screen to track aged debt and add any notes were required.

I have reviewed the installation documents in addition to some white papers and after completing setups all appears to be OK.

Some concerns have been expressed however with respect to patch levels. All of the above setups have been done without deploying any additional patches and for all intents and purposes the Collections screen is functioning normally. I would like to know what prequisite patches are requried to enable the Collections module in R12.
