Companies flagged as Vendors in Manage are mapped to Vendors in Dynamics SL. The “Vendor XRef” field on the Manage Finance > Company Finance screen needs to match the “Vendor ID” field on the Financial > Accounts Payable > Maintenance > Vendor Maintenance screen in Dynamics SL. Note: If a Vendor in Manage has a PO to be imported into Dynamics SL and the Vendor does not exist in Dynamics SL, a new Vendor will be created in Dynamics SL automatically.
