Select via Application Log Context

Hi Gurus,

when I want to display data from the Application Log I have to select the appropriate handles and load them into the memory. Someone knows how I can select the handles via context fields?

E.g. I have the fields MATNR, PLANT, WEMNG in the context. How can I select all handles that store data from plant 1000?

Thanks in Advance,

BR,

Steffen
