Availability Control - Error in triggering Warning Message

Hi Experts,

I am activating availability control for budget using Activation Type 1- Automatic activation. Set tolerance limit as 90 and using Action 1- Warning.

When i budget in CJ30 by copying 100 % planned cost, it gives a warning saying availability check and i save it as i felt it is a standard. SAP behaviour.

In project, when i confirm the activity till 100% actual cost posting i dont get any warning message at all. But i tried adding new activity and planned cost in the same project later. So when it exceeds even little more than 100 % budget value and i try to save it, that time the Warning message is triggering.

Please suggest a solution.

Regards,

Kabir
