I am using Enterprise Contractor 24.0 edition.

I have multiple fields set up for Vehicle Unit # and another for PUC status.  I originally set these up going thru Lists / Items / double click any Item, then go to Custom Fields, Define Fields . . . etc., 

After wards I added to our column display when entering Bills. 

I have a huge Fuel Bill that I only enter the summary for, but would like to import with vehicle numbers, etc.

However, I do not see that option in the IFF import file either and do not have enough experience with IFF files to worry about Errors.
