Create Offline Packages

Click the Add New button and type an appropriate Display Name, which is required.
If you want to include replicas in this offline package, click Edit Replicas, select one or more from the list, and click Apply.
Additionally, if you want to include tile packages in this offline package, click Edit Tile Packages, select one or more from the list, and click Apply.
Click Save.

IMPORTANT: Users can access this offline package only if they are members of the Portal for ArcGIS group that has access to replicas it contains.

NOTE:

There is no limit to the number of replicas or tile packages you can include, but keep in mind that the client has to download all those that you include. For efficiency, you should exclude unnecessary replicas and tile packages.
If an administrator removes a replica or tile package that was a part of a previously downloaded offline package, the next time a user launches the client application, the item is removed from the local client. If a replica or tile package is added to an existing offline package that has already been downloaded, the local application automatically downloads the new item upon the next launch.
