Change classic PO by SC change

Hello Community,

we have the following requirement in SRM 5.0:

1. User creates SC

2. Classic PO is sent to Supplier

3. Supplier sends invoice with different price

=> PO needs to be adjusted to fit to invoice

5. User changes SC

6. PO is updated

I know that in SRM standard this is not possible.

Mabye someone has come across a similar requirement and found a solution about how to "enhance" SRM.

Thanks in advance and greetings

    Hi Juilan,

    I know what you mean, but I cannot understand the business logic behind.

    From the other hand it also would be quite hard to realize technically the SC change once it"s ordered. Please consider the following points:

    - The changeability of the SC is controlled by the SC status. Once the SC is approved, it can't be changed any more. This would be the first point you would need to modificate.

    - How do you handle SC approval?

    - You need to take also care, that the event 'Setreleased' starts a new transfer for the SC. In this case double PO is created for the same SC.

    - When you modificate the SC to allow the change, how do you handle the SC versions? Is it OK for you that the last change version will differ from the actual version?

    - How do you make sure, that the processor updates the SC indeed with the correct price.

    Instead of this whole change, I would rather change the follow-on document type to 'always purchase requisition'. You can generate from the purchase requisition a PO automatically in the backend, and when you need, you can update the price later on.

    • Hi Julian,

      I would estimate several weeks for this modification effort.

      But what do you think about the PO creation?

      The requestor can also create directly the PO in the SRM system (even the extended classic PO can be created with backend reference), and there you can also use the workflow with the 1000 u20AC limit. If you want you can also use the completion workflow. This has the advantage, that you can change the price later on.

      In this case you can use the standard.

      Other idea, that you use a mandatory catalog ordering. In the catalog you maintain the correct prices, and the requestor can't choose a wrong price.

      For special cases the requestor can use the free text items which will be checked by the purchaser.
