Importing into Price Code file in 4.40 - took a client's file and exported, then imported back in, skipping any ""O"" (Override) records. Ran into this previously - keeps erroring out unless I manually entered the Price Code records (all I needed was the Price Code, ACCEPT). The import will bring in the description, etc, but did not like actually CREATING the Price Code records, apparently. Doesn't give you a helpful error.
FYI
