How can I import more than one Financial Document in a single import file?
Utilizing the group_id column allows you to group multiple Financial Documents into a single import file.
The group_id is a user-populated field and can be any alphanumeric you wish to enter. All records with the same group_id will be grouped into a single Financial Document within Unanet. For example, you may choose to use a numbering sequence or the Vendor Invoice number.
