We are attempting to migrate all of our 6.7 processing to 8.1 and I've been having a lot of headaches. One new thing just surfaced this morning. We have a map that translates an Ansi X12 transaction to a flat file. One particular field is set in the type tree to pad with <SP> to a fixed length of 8 in the translation. When we run the map under 6.7, it pads with <SP> to a fixed length of 8, no surprise. However, when we run it under 8.1, it pads with 0 to a fixed length of 8. I double and triple checked the type tree, and it is in fact set to pad with <SP>, and has been analyzed multiple times. Anyone have any ideas why it would pad with <SP> under 6.7 but pad with 0 under 8.1?
