Notifications on Missing Parent Connections

Scroll Home Prev Top Next More

When you create connections between source and target items manually, MapForce automatically analyzes the possible mapping outcomes. If you are mapping two child items, a notification message can appear suggesting that you also connect the parent of the source item with the parent in the target item.


This notification message helps you prevent situations where a single child item appears in the Output window when you preview the mapping. This will generally be the case if the source node supplies a sequence instead of a single value.


To understand how this works, open the sample mapping Tut-OrgChart.mfd available in the <Documents>\Altova\MapForce2021\MapForceExamples\Tutorial\ folder. If you connect the source text() item to the target text() item, a notification message appears, stating that the parent item "para" is not connected and will only be generated once in the output.

To generate multiple para items in the target, connect the source and target para items to each other.


To disable such notifications, do the following:


1.On the Tools menu, click Options.

2.Click the Messages group.

3.Click to clear the When creating a connection, suggest connecting ancestor items check box.
