ECATT - error in session start

Question

Hello!
I have a problem with an eCATT procedure which is a part of a Best Practice for All-in-one installation. When I try to run the eCATT, I get the message
"Error in session start. Possible causes: 1. Scripting deactivated. Contact administrator. 2. User not logged on within 00:00:40 seconds. 3. Too many sessions open."
The message appears when the eCATT tries to run the script "/SMB99/SE09_J002_J02 - Create Customizing Request". I don't know is this general scripting error, or specific for this script.
I have SAP_BASIS release 620, support package level SAPKB62039. The user has SAP_ALL authorisations. I have the parameter "sapgui/user_scripting = TRUE", "Enable scripting" in "Customizing of local layout", and "eCATT and CATT allowed" set. I have only one session open.
I don't know what else could cause this problem. Could you, please, give me some suggestions on how to resolve this?

while to tranfer the data from the through if any errors occurs until the errors are the complete the data is not tranfer to the sap system.
the system compalsory shows the errors .that errors are stored into the error logs (Trasaction is SM35).
so the sesion method should not return any value.
in call trasaction method data is directly pass to the sap system.
so its compalsory return the value.
because of the call trasaction is the funtion.
a funtion should return the value madatory.
