Hi Babu,
As Abinav indicated, a blocked order should not account for credit value update at customer level before it is released. lets assume that the customer as credit limit of Rs.100, where his credit value had reached 80.
suppose if the customer is placing an order for Rs.30 you will block the order, which is meaningful based on credit limit. but does it mean that since his order for Rs.30 is already blocked, you are not going to take any new order from customer for say Rs. 15?
