Weekend Learning: R12 upgrade issues and solutions for Oracle Payments

If you are still on EBS 11i, this weekend you should read the My Oracle Support article "EBS 11i to R12 : Upgrade Issues and Solutions for Oracle Payments" in note 1466998.1 to find out what patches you need to be applying with your upgrade so you avoid problems before they actually become problems for you.  Of course, if you are on R12 this would be worth a review just in case you have not encountered these problems yet and can patch your system to make sure you never do see them!
