Abnormal big number of user session generated when running script under vuser

Hi, all

 

I have been using the HTML protocol to record my script on the SAP portal webdynpro application. After I do all the correlation, I was able to replay it in vugen. However, when I simulate a run of let's say 5 vusers, I noticed that almost 200 SAP sessions were connected when all the steps are done. No failure though.

 

It almost looks like each step in the script is creating an SAP user session(from SM04/AL08) which is not right. Of course, if I only run the SAP application without LR, one user session is created. I am pretty sure I am not the only one seeing this issue. Please advise the fix for this issue.

 

Thanks,

Jonathan.
