Selecting 'All' means the type is determined by the record header.
If you select a specific record type, the header will need to be removed from the record input.
v0.4 records are the newer record type - they require dictionary fields for benchmark data.
Select 'Validate' if you want to check only the formatting of the record(s).
Select 'Load' if you want to also check whether the record(s) will successfully load into the database.
