I've this issue. I'm using SRM 5.0.
I've configured a product category mentioning it needs to go to sourcing only when the vendor is not mentioned. Otherwise it should bypass sourcing and after the last approval the PO has to be created in backend automatically. We are using Classic Scenario. Now i've this issue. When I create a shopping cart without vendor it goes to sourcing cockpit and from there when I fill the vendor information and create purchase order, purchase order gets created in backend. BUT when I provide vendor information in the shopping cart and Order it after all approvals, it doesn't create PO in backend. Instead I see an error in the error logs of Shopping cart mentioning.
<b>"Shopping cart 0040000365: Error creating the follow-on document"
I see this under <b> Application Monitors > Shopping cart > Local Errors </b>
Could someone please help me if there knows the solution for this or any note available for this.
