Analysing Large ST01 Files

Morning All,

Have been performing blocks of traces for some new process activities for Portal in our R/3 Dev system using the trace transaction code ST01.

Some of these trace files are very large, over 10,000 lines when downloaded into excel etc. Please SAP Security gurus can anyone tell me if their is an easy way or a tool to make it easy to analyse large ST01 files so that I dont have to check hundreds of duplicate authorisation lines.

Thanks

Steve
