Answer 1

Dear,
So in that case, I prefer to go for Consignment scenario.
Consignment u2013 the vendor provides you with materials which you manage on your premises as port of consignment stock. A liability does not arise until the material is withdrawn from consignment stores.
The stock supplied by the vendor is in the companies premises with the company having no liability for the same.  The liability for the company will only be affected when the goods are issued from the consignment stock for use.
Create consignment info record with proper tax code, create Po with item category K, maintain output condition record for KONS, process GR, no invoice verification done, but settlement is done through MRKO transaction.
I prefer this to be done once you receive the final report from SHOP floor. I think you got the point.
The material is available in your company premises. Let the work perform by all departments. Untill you get the report with heat details for final payment to vendor. Start the process as mentioned above, create PO with conditions, goods receipt and settle the payments.
I am getting this idea, any further ideas or suggestions, share.
