Originating Document #
This field works in conjunction with the recurring document feature.
If a financial document has been configured to recur (and therefore spawn new financial documents upon posting), this field will be populated with the document # of the original financial document (where the recurring indicator was originally established, that is, the first in the series). Should this be the original document (i.e. the first in the series), then this field will be populated with the current financial document # upon save.
