Serial numbers for subcontracting process

Hello Experts,

We are using SAP ECC 6.0 and trying to implement the subcontracting process with serial numbers. This scenario is focused on those materials that we need to keep track on how many times it has gone to repair (for example, a motor) by specific item. Suppose there's a material called "Material A". However, there are MANY "Motor A"'s, and thus, the need for serial number to keep track on the number of repairs each one has had.

So, having said that, the scenario is working so far. However, the user CAN'T type in the serial number of the material at the REQUISITION LEVEL. This can be done at the PO level and at the goods receipt level.

This brings a problem since the Purchasing dept. doesn't know the serial number. This information is known by the user, but there's "serial number" functionality in the requisition. Is there a configuration for this? Could it be possible for the serial number to be in the requisition and then inherit it to the PO?

We want this in order to automate the process.

The configuration we made was in the "Plant Maintenance and Customer Service" section, using procedures MMSL "Maintain goods receipt and issue doc." and POSL "Serial numbers in purchase orders". There's no procedure for purchase requisitions. If this can be also done from a Work Order, that will be just fine.

Let me know if it is possible or if you have any idea on how to do this.


Gilberto Gallardo.

    Serial no can be used for the following business transactions.

    1. Goods Receipt/Goods isssue and other inventory postings.

    2.sales orders and delivery notes

    3.maintenance orders

    4.production orders.


    1. create a serial number profile in customising.

    2. Assign the serial number profile in the material master record in work

    scheduling view for fert and raw material in plant data / stor2 view..

    Business procedures may be assigned in configuration to a serial number profile.

    The assignment to the serial number profile determines if serial numbers are required , can be assigned, must be assigned,are assigned automatically

    MMSL : Goods issue , receipts,stockj transfers,stock transport orders

      Hello nandha,

      Thanks for your quick response.

      Regarding point # 3 in your answer... what exactly does it mean by maintenance orders...? Can you create a Purchase Requisition from a PM order that already has a serial number in it?

      If this is the case how can it be done?

      Will the serial number travel to the PO so we can automate the process?
