I am using Gentran: Director to map from a flat file to an 856 4010 EDI file format.
I am new to EDI and mapping and am unsure on how to map the HL records, especially the parent ID number.
Usually, a HL segment starts, I mean, its first element, is a unique, normally sequencial number, starting with 1, then when you are mapping a subordinated HL segment you normally map the Id number the HL segment above (parent) has, like a tree.
here we have a Shipment level, then an Order level, and multiple Item levels, below O (order), the parent ID stills the same, and the Id will remain incremented by one, it must keep unique. But if you have a second O level your Parent Id will be the same.
