Does final adjusted production allocation key figure impacted on other key figures?

Dear all,

Currently I did not understand the meaningful of Final Product Allocation key figure except for using to order confirmation step.

However, I think after adjusting production allocation quantity, it should lead to change of production planned qty or stock transfer requisition qty because if case of increasing product allocation qty, we have to increase capacity and increate production. However, currently , after changing it, it does not impact on anything.

Please kindly share your experience.

Many thanks,

Jenny
