I'm having the following problem using JMeter to test an SAP ISA application. Here is the behavior I'm seeing
I have a data file with 2 lines of data. Each line represents a login and insert/update of data. When I run with more than 1 thread it seems as though the threads are not keeping separate sessions/connection to the SAP ISA webapp. What I see is 1 line of data runs successfully however all the other threads get an error from SAP ISA indicating that "Transaction xxxxxxxx is being processed by user xxxxx" Where user "xxxxx" is the 1 line of data which runs successfully. So in general, no matter how many lines of data I have or threads I use I'll get 1 which is successful and all the rest fail with the above transaction error message.
Has anyone seen this kind of behavior and can advise?
