This page summarizes information about ABAP Business Transaction Analysis (Transaction STAD)
To document any performance observations in a system STAD is an important tool. Statistical records are the entry point for the performance analysis. It provides a very good overview where the time in the dialog step was spent (database time, CPU time which is mainly ABAP processing, GUI communication, etc.). If deeper performance analysis (tracing) is necessary, it is clear in which direction it has to go.
