Cumulative Patch Certification with Applications

Numbers of questions coming for information about the certification of Cumulative Patches with Applications installation. First of all, it is important to clarify the types of Discoverer solutions to 'Apps certification' :

1. Custom Solution
   - Custom solution is built by customer and is not dependent on any 'Apps certification' ;
   - Custom solution is simply using the Discoverer native functionality to connect to EBS DB.
   
2. (2) BIS Solution
   - BIS is an Oracle pre-built and shipped with EBS solution.
   - This solution comprises of BAs, folders, workbooks, etc.
   - The 'Apps certification' means that BIS Dev team tests all BAs and workbooks with a new Discoverer version against EBS.
   

In any case customers using Discoverer 10.1.2.2 against EBS 11i are still fully supported and all new problems will be handled normally even reported to Development as bugs if needed. Concerning the Cumulative Patches, you can go for any Cum. Patch version higher than Cum.Patch 3 (6155500) (You may want to skip Cum.Patch 5 6472361, which I see is not fully stable).
