Credit Card Authorization (EBS Order Management 12.2.4)

Hi All,

We are using 12.2.4

We are in process to Implement Credit Card Authorization in Sales Order.

To Book sales Order we are using Credit Cards.

Example : Sales Order  having 3 Lines.

Line 1 - 100.00

Line 2 - 120.00

Line 3 - 130.00

During Sales Order Book the there will be a Card Authorization of :350.00

During Shipping process :  :Line 1 Shipped.So the Total Authorization was 350 and line processed is 100. So after the Payment Capture the there will be a amount of 200 authorization pending.

When I will do shipping for the Line 2, there will be a new authorization hit the Payment system, of amount (`120+130)= 250.

So my question is why there is a authorization of remaining Order Value,instead of only what i am trying to ship which should be 120.
