Filter Context in a calculation group

I have been working on this for a while and would like to share some of the findings and a solution in case anyone else would need to do the same.

I have two calculated group solutions: 1) one where I have  drill-through page, 2) one where I only have one page with the filters on this page.

My calculation group in located on a detail pagek which shows details for a certain store we have drilled us to. THe calculation group  shows growth for: store, city, chain, region and country.

In order to make the figures work, I needed to have drill-through pages for a sales person, city, chain and store. Note: if you skip any of these, e.g. Chain, the Chain figues on the detail page would not be correct.

The formulas I used in the calculated group were:

-Store: 

CALCULATE(SELECTEDMEASURE(), ALL(Customer[Sales Person]), ALL(Customer[Sales Region]), ALLSELECTED(Customer[Store City]), ALL(Customer[Chain Store]), ALL(Customer[Store Name]))

-Chain: 

CALCULATE(SELECTEDMEASURE(), ALL(Customer[Sales Person]), ALL(Customer[Sales Region]), ALL(Customer[Store City]), allselected(Customer[Chain Store]), all(Customer[Store Name]))

-Region: 

CALCULATE(SELECTEDMEASURE(), ALL(Customer[Sales Person]), ALLSELECTED(Customer[Sales Region]), ALL(Customer[Store City]), ALL(Customer[Chain Store]), ALL(Customer[Store Name]))

- Country: 

CALCULATE(SELECTEDMEASURE(), all(customer))

The order of elements in the formula makes difference.
