- Subject: Samuel Pepys & EDI transactions
- Lines: 57
-
- It has been VERY quiet on this list, so I thought I'd make some noise (besides
- it's also quiet at work for the moment - so I have time...).
-
- My topic of choice will be hierarchical EDI transactions (an explanation of
- the subject line - long ago Samuel Pepys re-designed the way the British Navy
- was organized by implementing the hierarchical, line of reporting structure
- which has become the model for armed forces world wide; eventually most
- organizations used it for lack of a better model...).
-
- Some background...
-
- We (the organization I work for) are in the process of starting an EDI pilot
- with our local telephone company. They will send us invoices for voice and
- data lines/services. The current practice is for the telco to send us the
- invoices on tape, in print image form (total size of the 2 files is over than
- 80,000,000 bytes...). Once we receive them they are processed by some custom
- programs which attempt to extract as much information as possible and then
- manually. The processing window is 4 working days before the invoice is passed
- to Accounting to pay. Looks like a good opportunity for EDI, as receiving the
- data in a more usable form would allow us to automate more of the processing,
- as well as make it possible to more thoroughly edit the data for accuracy
- (which I suspect is rather cursory today).
-
- The difficulty...
-
- There is a problem though - the 811 consolidated service invoice is SO big
- that it exceeds the capacity of the EDI translator that we have installed (and
- at least one other translator that I know of - both mainframe based). The
- problem is not the volume of data, instead the problem is in the design of the
- translators. Most EDI translators have the same basic design - they are table
- based. In our case the limitation is the size of the tables used to define the
- data segments and elements used in the transaction. (the limit on total
- segments is 100, the limit on combined segments and elements is 400). The
- transaction specification for the 811 that has been developed by Telecom
- Canada has over 500 segments and elements. Oops.
-
- So what is the problem, after all we could split the transaction up and have
- it sent in two (or more) pieces. Well, the problem is in the nature of a
- hierarchical EDI transaction - to reach the lowest level of detail (which is
- what you need to validate your invoice) you must traverse the entire
- hierarchy. So there isn't an obvious way (to me anyway) to split up the
- transaction.
-
- The request...
-
- Is there anyone out there with some experience in dealing with hierarchical
- EDI transactions? Any suggestions (other than new software...)?
-
- A footnote...
-
- The other area that keeps me busy is working with my clients. We're working on
- the next transaction in the business flow, which will be the 857 shipment and
- billing notice. Guess what - it's hierarchical too.
