Approving the plan data

Hi There,

Scenario:

I have a scenario where a person "A" keys in the plan data, and person "B" is a manager who has to review the plan data keyed in by the Person "A". "A" can REJECT or APPROVE the entries.

I cant use the DATA SLICE since by nature the lock will be on the INFOPROVIDER LEVEL. Other input queries been built on the same infoprovider will get impact.

Please throw some insights how to achieve using the IP tools (planning functions / FOX ) for my business scenario.

Thanks in advance
