Every time system create new production order after releasing sales order c

Question

Hi Guru,
FG material strategy: 82 (sales order creates production order).
After creating the sales order it goes in to credit block. Whenever we release sales order from credit block through VKM1, system has created production order. We confirmed this production order and delivered.
But after this sales person change the sales order value, because of which again sales order goes into the credit block and after releasing sales order from credit block system create new production order even if one production order already confirmed and delivered against the same sales order.
*Every time system create new production order after releasing sales order credit block.
Thanx & regards

PNU,
So, to restate:
In MD04, you have Unrestricted Sales order Stock ('E' Stock) on hand.
In the same MRP segment, and against the same Storage Location as the stock, you have a Sales Order requirement that was recently blocked and unblocked.
During the unblocking event, the system produced a new production order.
This is not normal.  If the above accurately depicts your situation, I would look for an altered Strategy 82, or a userexit.  SAP ATP (the beginning event of the Strat 82 process) will normally first check for the availability of stock.  Only if the stock is not available, then it will create the new production order.
