When processing order for the Enterprise user i can't login using the Test Enterprise Supplier Account.
1. When i click the email notification to Process Order, the Test Enterprise supplier is already created.
2. When Log in using username/password -
Trading Relationship is already active for the Supplier in AN buyer
The quickest way to overcome this issue is to create a new supplier in SAP and post a PO to that very new supplier. Once supplier registers, click on upgrade button and move the account to enterprise one.
If you cannot create new suppliers in SAP due to permissions. Go to supplier enablement tab on your buyer account and remove all trace related to your currently not working supplier. Once you do that - try to send another PO and go through steps above.
