How to get the supplier external category for punchout map set
We are trying to setup a punchout catalog for the first time. If I understand clearly the process, if no mapping set is defined when the requester will bounce back to his/her requisition (after adding item to cart) the system will fill the designation field with the item description but the category name won't be populated.
How can we make sure this doesn't happen? Do we need to set a mapping for the supplier entire punchout catalog? How can we obtain the supplier external categories to map them with the purchasing categories?
