Dynamic subtraction for a measure with multiple filters

[Wichi]

Hi all & Happy weekend 

I am looking for the correct way in DAX to have a measure written, which substracts the displayed values based on multiple filters. I posted the picture below and essentially I can have various filters (e.g. material, date, bucket, country,..) which are influencing the displayed value of my measure.

Now I would like to create a measure which substracts the displayed values in the buckets. 

For Example; Salesweek 202328, MSU Germany, I would like to know the result of  substracting Bucket "1" - Bucket "2"; in numbers 

151,858,04 - 208,192,09

Many Thanks!

Hi ! 

I do understand the point around the sample data, yet currently it is not possible for me to provide a sample dataset at this point. I was thinking to get a more generic idea on how to approach this (e.g. with summarize?)

So I put the tables below, does that help ?

Ingoing position

BPCL5MSUDesc	Bucket	ComponentLevel1	Sum of ComponentForecast	SalesWeek
Germany	1	Promo	151.858	202328
Germany	1	Promo	159.275	202329
Germany	1	Promo	250.468	202330
Germany	1	Promo	307.138	202331
Germany	1	Promo	242.284	202332
Germany	2	Promo	208.192	202328
Germany	2	Promo	122.548	202329
Germany	2	Promo	175.637	202330
Germany	2	Promo	279.969	202331
Germany	2	Promo	214.924	202332

The desired outcome as below as addition 

BPCL5MSUDesc	Bucket	ComponentLevel1	Sum of ComponentForecast	SalesWeek
Germany	1	Promo	151.858	202328
Germany	1	Promo	159.275	202329

Germany	2	Promo	122.548	202329
Germany	2	Promo	175.637	202330
Germany	2	Promo	279.969	202331
Germany	2	Promo	214.924	202332
Germany	Diff 1-2	Promo	-56.334	202328
Germany	Diff 1-2	Promo	36.727	202329
Germany	Diff 1-2	Promo	74.831	202330
