Dear Community, I am a new SAS Studio user (9.4) and am struggling with the following task. I need to merge two files. One is located in SAS WRDS Cloud (let's name it File 1), and another one is located on my local drive (let's name it File 2). File 1 is approximately 300 GB, so all manipulations must be performed in the Cloud, and then the final version of the merged file would be stored locally.  I need to merge File 1 and File 2 based on CompanyID and Year. When I try to sort File 1 by CompanyId and Year prior to merging, the system rightfully says that I do not have permission to manipulate that file (as it is a WRDS raw data file, the message is "ERROR: User does not have appropriate authorization level for library RBDX). However, I cannot download the file locally as it is too large.  What is the best way to merge the two files, and what would be the appropriate code? Many thanks for any help!   Best, Ana. ...
