How to create a jobsteps for a new user to run a report on portal

Hello Experts,

Is there any program that automatically creates a jobsteps for the new users for

a role??

My company BW roles are mapped with R/3. so whenever a new user is created in a R/3 role

it comes and maps with BW Role and creates that users automatically in BW.

Now the problem is if any new users are created in r/3 and mapped with BW. the report

fails to run for the new users unless and until they really login in to the system.

For ex: I have 5 new users which are created in R/3 and properly mapped with BW. But

report fails to runs for the new users.

ERROR: Jobs step fails for the User X

Is there any programe that automatically creates a jobsteps for the new users??

Please advice.

Thanks in advance,

Harish
