Try submitting the FMTSEARCH= system option as shown below in your SAS session before opening the data set in SAS Explorer. LIBNAME TCCTM 'C:\Data'; options fmtsearch=(TCCTM); SAS will now look in the TCCTM library for the format in the file: formats.sas7bcat and the formatted values should appear instead of the error when you attempt to open the data set from the Explorer window.
