12. When ready, you can run the import operation. Do one of the following:
You can right-click the table or file to be copied and select Import item. If the import succeeds, a copy of the table or file is loaded to memory on the CAS server that is specified in the caslib. The copy of the table or file can be selected from the In-memory data (available) list or the Sources tab. If the import fails, see General Usage Notes.
The Import item option is used to run a job that imports the selected data. You can review the status of import jobs on the Monitoring tab of the Jobs page in SAS Environment Manager. For more information about using this tab, see Monitor Jobs in SAS Environment Manager: User’s Guide.
For more information about local file import, see https://developer.sas.com/apis/rest/Compute/#upload-a-data-file-to-the-collection-of-tables.
If you right-click the table or file in the import queue, and the Create a job option is available, you can use this option to create a job request on the Scheduling tab of the Jobs window in SAS Environment Manager. You can then use the Scheduling tab to run or schedule the job at an appropriate time. For more information, see Create Import Job Requests. After the import job request is run, a copy of the table or file is loaded to memory on the CAS server that is specified in the caslib. The copy can be selected from the In-memory data (available) list or the Sources tab.
