Hi all,
Usually , in case of sub-contract, the production order and the related sub-contract purchase order are marked with each other.
Also, the purchase order cost (quantity*unit price) is the cost that gets added to the production order.
But in this specific client's case, the sub-contract purchase order cost is different from the sub-contract cost that has got added to the production order.
Screen shot : 1 Sub-contract production order BOM lines - service items and related sub-contract purchase orders

Screen shot: 2 Realised cost amount added to the sub-contract production order for each of the sub-contract service item

Actual purchase order value for the sub-contract purchase orders:

As it could be seen in screen shot 2 and 3, there is absolutely, no correlation between the realised cost amount in the production order for the sub-contract service items & the actual cost of the production orders.
(1) Though the purchase orders are created from the production order, how the purchase cost and the cost loaded to production order varies
(2) From where does the system picks the cost to be added to the production orders?
Thank you very much for your support in advance.
Regards
Sriram
