Hi Sharu
Even if you have Price Control S, MAP is still updated, but only for name sake. It does not impact your Inventory Valuation at all
The important point that you should check is: Once your Std Price is 8, and you created a PO for, say. 10 - At what Price is GR posted - 8 or 10?? I am sure it will be 8
As long as it is 8, you must not bother if the MAP is still updated with 10... That is only name sake
If you want to revise your std cost, change it from MR21.. Hope it helps
Rgds
