Important Notes

Use

The exceptions of the SAP Tree Model do not set messages.

You must never ignore exceptions of the SAP Tree Model methods or flush calls. If an error occurs, the automation queue processing is terminated. This affects all of the controls in the same internal session. Once an error has occurred, the internal session affected may no longer work with controls.

The SAP Tree Model is not suitable for displaying non-hierarchical lists, since all root nodes must always be transferred to the frontend. Consequently, long lists can cause performance problems.
