Thanks Prabhar, For multiple downpayment we will total the amount recived from the customer against all open orders. We will keep 10% amount as the amount mandatory for open sales orders. Thus advance payment is for total sales orders. However at time of delivery we will only allocate the amount in such way from advance payment that 10% deposit requirement for remaining sales order is always met.
E.G. 1000$ SO, customer advance payment is 100$. Credit check pass.
Now delivery 1 for 600$, release 60 $ from advance payment and keep block on remaining 40$ for remaining open order of 400$. At time customer has to make prepayment of 540$ for delivery of 600 $. I am planning these based on adding custom fields in BP for credit check, as these segregation is not planned in AR.
Do you have any suggestion on creating these kind of check rule. Thanks
