No production order

austin

Hi experts,

My environment is NAV 4.0 sp3. Cronus databse , No customizations.
When it comes to set up Components at location is Blue.
Combined MPS/MRP caluc = yes
I created a Item A ( Finished item). Reordering policy = Fixed reordering , Replenish = productin. Inventory = 0
For Above item two BOMs B, C.. (Inventory = 0), Reordering policy = Fixed , Replenish = Purchase.

I created a sales order for item A = 10 Location is Blue . And I released sales order.
When I run the Planning worksheet it is not showing about my production order that means sales order.
But it is showing only components B, C with quantity to make Item A.
Y my planning worksheet is not showing production order.
Then how can i know how many production orders has to create per month ?
Then what is the use of Planning worksheet. :-k

Thanks and regards
