The LIBNAME statement should reference a folder, not a file. Your LIBNAME statement provides too much information:
libname detData "\\csbs-cfs1.csbs.utah.edu\home_i\u1052325\Downloads\detroit.sas7bdat";
Instead, cut it down to the path to the folder that holds the data:
libname detData "\\csbs-cfs1.csbs.utah.edu\home_i\u1052325\Downloads";
After that, you would refer to the SAS data set as:
detData.detroit
So it's a two-part name, that references both the LIBNAME and the name of the .sas7bdat file. In context, perhaps:
data inventory;
set detData.detroit;
run;
