Delivery Id is 0 in invoices
I am working on a issue where there are two invoices . The invoice grouping is done based on optional attribute ie. delivery id (interface_line_attribute3) . The delivery id for one invoice is 0 and the lines in interface tables are purged.
I m trying to find out why the delivery id is shown as 0.
In the other invoice their is proper delivery id .
Thanks in advance.
