Following is a list of the approved EDI version 4 ANSI X12 documents.
You will likely only need a small subset of the documents listed - even in the series relevant to your business. If your unsure which EDI documents you need, you should ask your Trading Partner to provide their EDI integration manual.
Also, although their are written "standards" for each EDI document, the standards are written very loosely so that the Trading Partners, themselves, can decide on the specific structure and format, although, more often than not, one Trading Partner is dictating the format to the other. In an "ordering" process, the buyer in the scenario will typically be able to dictate the format to the vendors.
