The system holds the sales order although the credit limit allows booking

Hi,

Please help us on the below issue, it is as follows.

1 - We have customer number 1111 and he has ZERO balance.

2 - The customer credit limit is 1200.00 and he has paid a check with amount 1000.00 as a confirmed check receipt.

3 - According to the above he has a credit limit as 1000.00 + 1200.00 = 2200.00

4 - We have issued a sales order with amount 1500.00 and when we book it we face a credit limit hold as screen shot below.

Now we would like to know why the system applied a hold although the credit limit allows to book the sales order.

Thanks

George
