Starting a process chain after completion of another

Hai,

We have a process chain where an ODS named ZODSREP gets loaded with data along with other FIAR data targets. I created another process chain that has flow that starts with loading ODSREP and then loading others targets in the flow and so on. Now our policy is to EXTRACT ONCE AND USE MANY TIMES. I have to make an arrangement in such a way that my chain starts only after the ODS is completely loaded. Both the process chains are daily chains.I thought of few options like making the first one as a local process chain in my process chain and then go on. But I shouldnot command the other chain. I think we have options like starting a chain after completion of a job or an event. Does that help? or are there any other better ways? Can somebody please tell me how I can do this?

Thank you.
