Project Supplier Material Management

Hello Experts,

Background:

Purchase Component Method ‘Customer Order’ is not available for Project Deliverables in IFS Cloud. This has lead us to switch to ‘Supplier Material’ as the purchase component method. 

Current Situation:

We need to deal with many supplier component parts. If we take once scenario,

1. Supplier material is connected to a project deliverables demand part. (project supply option is 'Purchase')
2. We don't have neither the parent or the supplier material part in stock
3. We receive the supplier material part
4. We ship it to the supplier
5. Supplier receives the part and we receive the parent part from supplier

Challenges:

Given the amount of supplier materials we have to deal with, the challenges we are having,

1. How can we monitor whether the supplier material has arrived ?
2. What standard functionalities of IFS we can use to ship the supplier material (we have been testing with shipment orders but can we set up the shipment orders/shipments to be created automatically by standard? ie: create a shipment order upon parent PO release and shipment lines will be created upon receival of the component parts?  Automatic creation of shipment was a possibility in customer orders process but it is not available for project deliverables in cloud)
3. Are we able to invoice supplier material from the parent part supplier (This was also possible with the customer order process) and can we consider the inventory costing when invoicing, like it is with the customer order process. 

Greatly appreciate your comments/suggestions.

Thank you all.
