How can we reduce Commitment Balance

 Hi,

I have a requirement regarding Commitment usage.

I will explain the scenario as follow.

I created one Deposit Transaction on behalf of Customer X with an amount $ 50000 .

I used the Commitment by using a sales Order of $35000 and also invoiced.

Now the Commitment balance has been reduced to $15000.

Now again the Same Customer came and he want the goods for $50000 again and also he paid the remaining balance of $35000.

Now i want to use this balance in the Sales Order  in a Single Line.

How can i make the Commitment to be fulfilled with the $ 50000.

Here the problem is for a Single invoice transaction, we can apply only one Commitment.
