Hi Mohan,
If you are looking to track tcodes that are used when a particular user
logs inn and start working you can use ST01 to do that.
STAT and STAD statistics records
SAP transactions STAT and STAD enable the analysis of individual dialog step statistic records (STAT records) to gain furhter understanding of the nature of the performance of the SAP system. At the completion of every step (which can include dialog, batch, spool, update, and so on) SAP writes a corresponding record in a file on the application server, detailing the response time characteristics of the step. Subsequently, these statistics are analysed by SAP jobs to become the statistical data behind transaction ST03, which is commonly used for SAP performance analysis.
Transaction STAT operates on the stat file of the application server where it is executed, whereas transaction STAD searches the stat files of multiple application servers via RFC calls to those servers. As such, STAD is a superset of transaction STAT, and it commonly is used for gaining an overall picture of the SAP system in question, as well as searching for records where the application server of execution is unknown. Transaction STAT is used when the search of stat records is to be limited to the application server in question. When displaying results, both transactions give the same data from the same source, namely the stat file.
These individual stat records can be used to determine various performance problems that can be remedied by a variety of means. It should also be noted that because individual stat records are the lowest granularity of statistics, they are subject to one-off effects in the system that result in spikes affecting single transactions. Generally, before starting to conduct more thorough efforts to improve performance, it should be determined it the problem in question is more than a one-time occurrence. Additionally, the information about whether the problem is seen on all application servers in an SAP system or is limited to one or a few of the application servers is valuable in planning a course of action to determine the solution required.
Cheers
Mohinder
