This is probably very specific to my company's set up, but it's worth a shot. We have about 6 custom segments called A, B, C, D. We then have 6 custom transaction line fields called 01. A, 02. B, 03. C, 04. D. So the only difference is the numbering to put them in order. They are populated by the same lists. Our expense reports use the custom transaction line fields (01, 02, 03) and our vendor bills use the custom segments (A, B, C, etc). When the company implemented NetSuite, they implemented a third party expense report system at the same time, so I believe it was probably related to that. Does this make any sense to any one with more experience? Or should two transaction types probably be using the same custom fields?
