Event on close Browser to unlock Data

Hi experts,

I have an OVP Floorplan and the problem is, that by closing the Browser, all Data Locks remain in SM12.

Is there an Event or Method called before closing the browser or how can I Unlock the Data?

I've red, that the Method WDDOINIT of the Application Component Controller is called, but how can I access this Method.

I have Feeder-Klasses for the UIBBs and an Assistance Class for the Application Component Contoller, but there is no Method WDDOINIT in this Assistance Class!

Thanks and regards,

Sebastian
