We are trying to determine how to trigger an ION workflow when a particular document is uploaded to IDM. We are using a custom doctype (OE Delivery POD) when uploading certain files to IDM. Currently we have 5 attributes that need to be filled in. We would like to enter just the key attribute (Order Number in this case) and then use a workflow to query the ERP and fill in the other attributes - all found on the Order Header.
