popup message from background job

Hi, abap experts,

I have written a programm, which will end the user sessions for those, who are using one special transaction code. Before that the programm will send a popup message to these users (with function TH_POPUP). It works fine.

Now this programm should be executed as a background job. And it is aborted every time, because of the TH_POPUP function.

Does anyone know how to send a popup message from a background job?

best regards

Yong
