ODBC for AR_InvoiceHistoryTracking (StarshipShipVia field)

Table: AR_InvoiceHistoryTracking

Field: StarshipShipVia

I check the FileLayouts and it says that this field is 15 characters. When I pull this table via ODBC, I can only pull 15 characters. However, when I view the data in DFDM, there's more than 15 characters in there.  Is there no way to pull the full field data?
