What is the mechanism behind

[wfrst2008]

In this file, some schedules are created.
But where are the locations storing the schedule content ,
that is the text ? and how the "filter" in the schedule properties
can be replaced by a project parameter ?

Any helps is much appreciated

These were set up as 'Schedule Keys'.
This is a nice little workaround that allows us to create text formatted like a table. There is no real object containing data, it is just text. That also explains why the schedule can't be filtered.

The secret is schedule key, I never use it before.
Will go study this topic to learn more related technique.

Thanks
