idoc-error.jpgDear Team,

• 1.We selected “Doc Type/Purc Org/Vendor

• 2.And defined the vendor

• 3.WE20 Setting

Purchase order idoc setting is done under Partner type LS-> Ariba as outbound parameter

• 4.Order confirmation idoc setting is done under Logical System DEVCLNT200 as inbound parameter

WE are successfully able to send the PO from ECC to Ariba system but when we are sending the order confirmation from Ariba to ECC, we are getting below IDOC error:

I checked in WE20 Partner Type LI, and vendor is maintained in LI
