Sample 55054: PROC SQL can be used to identify data representation and encoding for all data sets in a library
SAS® data files that match your session encoding are considered to be native, whereas data files that are encoded differently are considered to be foreign. Cross-Environment Data Access (CEDA) is an underlying SAS technology that surfaces foreign data sets to your current SAS session. CEDA has some limitations that are explained here.
Should the processing capabilities of CEDA be insufficient for your use, consider copying the foreign data sources into a native data representation or encoding.
The sample code on the Full Code tab illustrates how the SQL procedure can be used to identify data representation and encoding for all data sets in a library.

If you want to identify which data sets in your SAS session will trigger the Cross-Environment Data Access (CEDA) notes or warnings, try the sample code below. This was extracted from the blog "Finding the FOREIGNers in your SAS environment".
/* To run this code, use a valid path to a library of mixed data representations and/or encodings */
libname test 'c:\'; /*<---add a valid path */
%let Library = TEST ;
proc sql;
title "Encoding of Data Sets in &Library";
select memname, datarep, datarepname, encoding
from sashelp.vtable where
libname="&Library"
and memtype = 'DATA';
quit;
title;
