AF source element replication

  • Last UpdatedJan 30, 2023
  • 2 minute read

When a source element is selected in the data source, the following are replicated:

  • Unit of Measure Classes and Units of Measure

  • The selected source element and its descendants are replicated. Also replicated are referenced library objects like:

    • Element Templates

    • Enumeration Sets

    • Tables (see exception below)

    • Categories

    • Reference Types

What is not replicated

The following items are not replicated:

  • Analyses and Notification objects and templates

  • AF Tables that are linked

  • AF Table Connections

  • Event Frames and Event Frame Templates

Descendants Not Parented by Members of the Source Element Hierarchy

Some of the descendants of the source element may not be parented by members of the hierarchy. To export the source element and its descendants, these non-parented descendants are re-parented to one of the descendants on the destination. An example of this is:

Source Element A.

A has a child element B.

B reference C, which is owned directly by the database.

Figure 1: Source element hierarchy

Figure 2: Parents of element C

From the figures above (figure 1 and figure 2), C is referenced by element B but owned by the source database. Note the check box on the Source Database icon indicating the true parent.

When the A is chosen as the source element and replicated to the destination, C is re-parented to B.

Figure 3: Replicated destination element hierarchy

Figure 4: Parents of element C

From the figures above (Figure 3 and Figure 4), C is now owned by B on the destination.

Note: Even though B owns C on the destination, changes to C on the source are redirected to the C on the destination.
