Gentran: Heirarchical Level: How to map?

[kclark747]

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.

Any help or suggestions would be appreciated.

Hi kclark747,

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.

...
HL*1*0*S
...
HL*2*1*O
...
HL*3*2*I
...
HL*4*2*I
...
HL*5*2*I
...
HL*6*2*I
...
HL*7*2*I
...

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.

In a tree structure you'll see

HL*1*0*S
+HL*2*1*O
+HL*3*2*I
+HL*4*2*I
+HL*5*2*I
+HL*6*2*I
+HL*7*2*I
+HL*8*1*0
....

Hope this helps
