Tips & Tricks: Checking Whether an Object Is There
In any application, there are always central functions which control a generic process. These functions request reporting-specific functions from the central area. If, for example, a report only requests data when needed, but is supposed to be directly updated when a favorite is activated, the update must be triggered by the central document.
Here, the problem arises that there may also be reports which are always up to date. In this case, the central function must not activate the button for manual update because this would not exist in this report. Thus, there would be an error report.
