Subject: Re: Overriding Timing Parameters Specified in a Business Process


Do you mean I have to first create a new business process by substituting
parameter values for an existing business process, and then have the
CPP/CPA refer to the new business process?

I was hoping to be able to do the overriding without having to create a
new business process. Up to now, RosettaNet's policy has been to control
the specification of partner interface processes tightly.

The CPP/CPA allows certain BPSS parameters to be overridden, so
why not the timing parameters?
