Need help on calculated column which relates to multiple rows

[Anonymous]

Hi all,

I am relatively new to Power BI and DAX and I am having some issue with the following data. I would like to find out which relation numbers have ended in the previous year. However, some relation number have received a new license number so they should not be included. 

To illustrate, relation number 1829 had a license number that ended in 31-dec-2017, but they received a new license number. 

The relation number 1444 had a license number that ended in 31-dec-2017 and did not receive a new license number. I would like to filter on those relation number that had their license number ended and did not receive a new one. 

License number	Relation number	Starting date	Ending date
9809	1829	01-jan-10	31-dec-17
11907	1829	01-jan-18	31-dec-30
10023	2509	01-jan-12	31-dec-30
8338	1444	01-jan-08	31-dec-17
15222	3898	01-jan-15	31-dec-32
5944	983	01-jan-06	31-dec-15
14888	983	01-jan-16	31-dec-28

This is the preferred output:

License number	Relation number	Starting date	Ending date	Broken relation
9809	1829	01-jan-10	31-dec-17	0
11907	1829	01-jan-18	31-dec-30	0
10023	2509	01-jan-12	31-dec-30	0
8338	1444	01-jan-08	31-dec-17	1
15222	3898	01-jan-15	31-dec-32	0
5944	983	01-jan-06	31-dec-15	0
14888	983	01-jan-16	31-dec-28	0

Thanks in advance.

@Anonymous Please try this as a "New Column"

BrokenFlag = IF(CALCULATE(COUNTROWS(Test157),FILTER(ALL(Test157),Test157[RelationNumber]=EARLIER(Test157[RelationNumber]) && Test157[EndDate] > TODAY()))>0,0,1)
