Data file is in a format that is native to another host

Hi! I am reading in a SAS data file but it still shows in the log that :

NOTE: Data file EGFR.REPATED_MEASUREMENTS.DATA is in a format that is native to another host,
or the file encoding does not match the session encoding. Cross Environment Data Access
will be used, which might require additional CPU resources and might reduce performance.

I am working with large datasets and the total processing time is way too long. Is it possible to pre-process the data into a dataset that is "native to SAS environment" so that I can use it later in other steps? Thank you so much!

Yes, just copy it over. The new WANT dataset will be in your native format. In general, moving data to your work library will allow for faster processing, but if it's a large file may take it's own time.

data want;
set egr.repated_measurements;
run;

Look into proc migrate. I had a similar issue as yours a while ago and this fixed it.

libname Source <engine> 'source-library-pathname';
libname Target base 'target-library-pathname';

proc migrate in=Source out=Target;
run;
