Cumulative measure of members

[Anonymous]

Hi All

I am trying to create a measure of the membership of an organisation as a time-series. For each record of member, we have a field for 'Joined Date' and 'Valid to Date' (either the date their membership ended or the time in future their membership is valid to) Ideally I would like to create a column which has the cumulative number of members at the point that the particular member joined.

I have seen solutions using DAX for versions creating a cumulative tally of sales, however this wouldn't work exactly, as the members who have left previous to that point in time need to be removed from the tally. 

Any help would be gratefully received.

Kind regards

Robin

Take a look at these two Quick Measures as I think you want something like them.
