Process chain scheduling with event

Dear All,

I am fresher in BI.

I am trying to schedule a process chain with an event. once the first chain is finished i want to schedule one more process chain. i created the Event in TCODE SM62. But i dont know how to define a parameter for that event and also please let me know how to use that event to run the CHAIN B after finish of CHAIN A.

Thanks in advance.

thanks

chaitanya.
