Synchronizing Data

When you load network data or create a network graph, SAS/GRAPH Network Visualization Workshop synchronizes your node and link data. Synchronization ensures that the node data set contains all the nodes that are represented by the FROM and TO values in the link data set. If any nodes are missing from the node data set, then SAS/GRAPH Network Visualization Workshop displays the following prompt:

Regardless of your choice, the underlying data set is unchanged. The next time you update your data, it is recommended that you add the missing nodes to your node data set in order to avoid receiving this message.

The data must be validated before it can be synchronized. If you attempt to synchronize data that has not been validated, SAS/GRAPH Network Visualization Workshop validates the data first. For more information, see Validating Data.

SAS/GRAPH Network Visualization Workshop synchronizes data automatically when you load network data or create a network graph. You can also synchronize your data manually.

There are two ways to synchronize data manually:

If your data has already been synchronized, then these options are dimmed, indicating that they are not available.
