workflow

Hi All,

I need some help regarding workflow.

Is it possible to trigger a workflow from an existing workflow?

Basically I want to test a scenario where after an existing work flow is approved, based on some condition it should trigger another workflow. The second workflow is for a different business object and will have a different approver.

eg . I have a PO (created against a contract) work flow. When i approve this PO, this should trigger work flow for the contract .

Can any one provide some information or links and how it can be done?

Thanks,

Ramesh.
