How can I set up purchase-to-order much the same as make-to-order

Hi all,

I apologise if this is posted in the wrong place but this is my first question that I couldn't answer by searching other posts/articles so I'm reaching out for some help and advice.

In PP, you can use a planning strategy to execute a make-to-order process which creates a production order specific to a sales order. Is the same possible within MM for creating a purchase order specific to a material required for a production order?

My example is this:

The BOM for FINI_ABC contains:

1 piece of PACK_1 (label)

1 piece of PACK_2 (container)

If I create a production order for FINI_ABC, MRP will obviosuly create requirements and purchase requisitions for both PACK_1 and PACK_2 materials. What I would like to achieve is for the production order number to be held within the purchase requisition and subsequently the purchase order.

This is required so that when the Purchase Order is created and sent to the vendor, they also receive the corresponding production order number. The vendor is then able to deliver the PACK materials packaged together for production which obviously eliminates some manual handling in the production warehouse.

As you see, it's very similar to Make-to-Order but I don't know where to start..........

Any help or advice to point me in the right direction would be very gratefully received.

Many thanks,

Rob
