Multiple Material Numbers to use one Info Record

Question

I have several material numbers that I have recently set up as Subcontracting special procurement. All of these numbers use one quote from our vendor. How do I assign multiple numbers to a single info record?
Thanks for your assistance!!

Answer 1

SAP knows 2 kind of subcontracting scenarios, a purchasing route and a production route.
in the purchasing subcontract scenario you order the finished material with item category L, you can see the components in the purchase order and you consume the components when you post the goods receipt to  this purchase order.
in the production route, you create production orders to "manufacture" the finished and to consume the components, the purchase order is only to procure the service. you do goods receipt and cosumption in reference to the production order, and you do a goods receipt for the service in reference to the purchase order.
if the info record is without material number,then you cannot have a permanent  link to a material if you use the purchasing route.
Usually SAP will propose the info record as source when you assign and process requisitions in ME57. I doupt that SAP will propose info records without material number for requisition with material number. so the only chance to assign such info record to a PO to get the price defaulted would be manual entry of info record number in ME21N (F4 search help is available)
in the production subcontracting process you can enter the info record number in the recipe, so you can establish a permanent link in master data. So SAP exactly knows which info record price to pull for the service orders. and in this process you can enter one info record number in several recipes.
