Question -------- For now, I can use translation table entries or map a segment using a formula to do the same thing. Which is more efficient? Answer ------ The formula method. For example, should your inbound values map to an item with the prefix of "ITM" in order to map to your order's items, then should you use the translation table method, every time you have a new item, you would have to make a new translation table entry. That, you'd want to avoid and have the system do automatically, even if you have one or two exceptions (which you'd handle in your formula).
