I went through the link and found a similar case of mine where they would like to tie up two fact tables to a single calendar.
They are suggesting to use linked dimension for calendar master.
But due to the lack of clear example, i have difficulty further probing this.
Would you be able to help further with my example?
Take a look at this tutorial.
