We are in the process of migrating from the 61 to 71 environment and we are getting the below error while trying to send the Rosettanet 3A4 Purchase Order to external customer using the delivery methods as HTTPS and providing the necessary Host,port and Location.
The Process model is getting triggered and its failing at the step Send PO Request of the standard PIP action initiator model template
Any help is greatly appreciated
