The BubbleEvent parameter was created in order to give the SDK developer the possibility to replace SAP Business One application handling of the event.
The default value of this parameter is TRUE.
If you want SAP Business One application to continue its original code, don't do anything.
If you don't want SAP Business One application to do its original code, than (and only than!)
You should change this parameter value to FALSE.
With the following code:
BubbleEvent = FALSE
BubbleEvent = TRUE
Since this can cause collisions between several add-ons.
