@89sankar

If a library is defined as pre-assigned in SAS Metadata then the library definition gets executed during SAS invocation. 

For pre-assigned libraries via SAS Medatada SAS DIS won't generate a Libname statement in the deployed code.

 

If using pre-assigned libraries pointing to databases then I'm normally also using libname option defer=yes so that the actual connection to the database only gets established once you actually use a table from that database in your DIS job.

 

In case your server is locked-down then using pre-assigned libraries allows you to use paths to folders which are otherwise not accessible. That opens up quite a few opportunities when it comes to securing an environment and controlling which users can access what using SAS.

Pre-assigned is when the DI Studio job early on that the library is assigned by central configuration. Either by an autoexec or via the metadataibrary registration.
