Release of Balance Project Budget

Dear Team,

I have configured the budget profile in PS with setting that  only overall budget is possible and availability control will be activated at time of release for released amount from Overall budget.

I have Created created below structure and updated orginal budget in CJ30.

A.1000      : 2000 INR 

A.1000-01  : 2000 INR 

In CJ32 I have release amount

A.1000      : 1800 INR 

A.1000-01  : 1800 INR 

Tolerance limit set 100% for hard stop error.

Now, during execution once my 100% budget exhausted (i.e. 1800 INR), I want know how should I release balance 200 INR budget (Balance 200 INR to release from Original budget)

Do we need to go in CJ32 again and overwrite 1800 INR to 2000 INR or we need to do supplement?

Appreciated your inputs.

Regards

Rajat
