well first of all TLE means Trust Link Enterprise, is Harbingers translator, as you know Harbinger bought Premenos, Premenos' translator is EDI/Open, I went for training with Premenos about two years ago, I did not really learn very well on that training, but now I can get around, I have been working with it for about two years.<br>
If the data file extract is the same for all your trading partners, you can create one generic layout for each invoice, purchase order, etc and link it to many maps, each trading partner has its own map(needs). <br>
This way you know what each trading partner wants and grab it from the layout to link it to the map. If you want you can send me some test data output from your application and give you an idea if I can help. what does ASN stands for?
