When Engineering Change Management is used with Product Lifecycle state, there is a business process for purchase orders, but when it is set to blocked, it still allows requisitions. Understand that requisition can be used for both purchase and transfer orders, but it would be good to be able to disable the requisition process consciously.

There is also the issue of blocking receiving products and blocking invoice processing. Often when a product is being phased out, we have outstanding backorders and invoices that we need to process. Enable with warning serves the objective but it can't be warning forever. We need to be able to disable raising POs but enable downstream processes. Suggest a separate process for product receipt and another for pending invoice.
