- Subject: RE: 811 EDI transactions
- Lines: 31
-
- While I was writing the note that explains what a hierarchical EDI transaction
- is, it struck me that it might be possible split apart an 811 to make it small
- enough for us to process.
-
- Part 1 of the 811 would be the summary information, which is the higher levels
- of the hierarchy. Splitting off summary info is pretty straight forward.
-
- Part 2 of the 811 would be the detail information. To reach this level you
- must traverse the summary levels, but you design the data map used by your
- translator to only recognise those segment/elements absolutely required to
- allow you to positively identify the 'owner' of the details and ignore the
- rest.
-
- This technique would require the receiver to process the input 811 transaction
- twice - once for summary, once for detail. There would also be a requirement
- for an application to 'glue' the invoice back together. Sounds ugly, but it
- might work.
-
- Re some of my complaints about 811's - I wouldn't want the designers to have
- used the limitations of the available EDI translators as a design criteria,
- but I (to echo Randall) wouldn't mind if they'd used a data model. There seems
- to be a trend in X12 transactions to bigger, more multi-purpose designs. The
- 857 Shipment and Billing Notice (which I'm much more familiar with) is
- designed to be both a shipping notice and an invoice - and oh by the way if
- you need a bill of lading for your carrier - you can create it from the 857
- with almost no effort. As Randall might say - its a great idea until it hits
- all of those legacy applications (millstones) that we all have.
