Filter text value differences between date periods

Hi v-juanli-msft,

Thank you for replying with this suggestion and providing a pbix file.  It's very close to doing what I need, but there's something that's not quite as I'd like.

In the example we used - the outcome for item 2 is the issue: 

(Assuming the data filter is set from 1/6/2018 to 1/8/2018...) 

1/6/2018 - Item 2 correctly has measure 1 set to "1" - i.e. it hasn't changed since this is the first occurence in the time sequence.

1/7/2018 - Item 2 correctly has measure 1 set to "2" - i.e it has now changed to "yes" from original value "no".

1/8/2018 - Item 2 incorrectly has measure 1 set to "2" - i.e. even though the value changed back to "no", which is the same as the first occurence in 1/6/2018.  So ideally I'd like it to NOT consider this as a difference during this period, as the filtered start and end period value has remained the same - i.e. "no" (even though it may have changed at some point between).

I hope that makes sense?  Would you happen to know how your solution could be changed to factor that in?

Many thanks again for your help with this.
