Multiple Events & Triggering of Workflow

Dear All,

I have a requirement in which -

1) A workflow should trigger on two events i.e. 2 different tcodes, it is possible for a single workflow triggering from 2 events ?? if yes, kindly explain.

2) The workflow should trigger on a particular date given in the tcode, like order completion date i.e. i should program the workflow for advance. How ??

3) There is a requirement of sending mails to the respective persons in the organisation, these email-ids are stored in a z-table, how to achieve this ?

Any assistance provided to clarify the above issues will be really grateful.

Thanks,

Saurabh Chauhan.
