Querying table for content in ST22.

Dear all,

I have a requirement to gather certain abap short dump e.g. like only Error Id is TIME_OUT into an xls sheet. System throws out nearly 100+ TIME_OUT error each day and we want to put that into an xls sheet. So I?m thinking to write an abap but I need help with getting started with it. Can someone out there show me the way? thanks
