@pchegoor1 , The physical path for Path-based CASLIB is located to the CAS Controller Server or a NFS drive mounted to CAS Controller server. There are two types of mechanism to load CAS (In-memory) from source data location, one is client side load and other is server side load.
The user interface which can access CAS like SAS 9.4x, SAS studio , Python etc. are clients and data can be loaded from there too called client side load. In the client side load the data files are available and accessible from client machine only. The file transfer data connector is used in the CAS load action to load these data files.
The second one is server side load, where the data files/table available and accessible to CAS controller server and can be loaded to CAS using data connectors like PATH based CASLIB, and Database CASLIB.
To load CAS from client side data using SAS studio, user does not have to physically place the data file onto CAS Controller server. It's just different syntax and mechanism used to load data from client side. Here is an PROC CASUTIL example where a SAS datasets table being loaded into CAS. Notice the "load data= ..." statement rather than "load casdata=..." statement .
proc casutil ;
load data=sashelp.prdsale casout="prdsale" ;
run ;
