Mukesh,
I believe you have posted the screen shot from the log. and it is missing the execution of SU01.
which means your data is being read fine (as indicated by Import details) but script is not executing SU01. You may want to check if recording of SU01 is done correctly.
I am not sure if creating mass user creation SeCatt scripts are worth it when only input is User ID for two reasons, first you will still have to go and edit each user for other attributes and second, these scripts don't get used as frequently because it is not everyday there is a need to mass create users. However if someone reads the wrong input data then you have another problem at hand for cleaning the mess. Plus with catt scripts you have to have system settings updated to allow scripting.
