Restrict all goods movements for materials untill the latest costing run ex

Hi dudes,

1 here i have a requirement that i need to restrict all goods movements in the month for all materials(SFG,FG) untill the latest costing run(standard cost estimate) on 1st of each month.

2. Can we restrict the status of process order in such a way that Conformation can be done only after the goods issues against production order. The goods receipt can be done only after the conformation of the process order.

Thanks in advance.

Robert.
