Variation instead total in Matrix

[gomezc73]

Hello Experts,

 Could you please help me with this issue?

I have a table with monthly sales by Year/Month, like this

product code	description	year	Jan	feb	Mar	Apr	May	jun	Jul	Aug	Sep	Oct	Nov	Dec
M01	Product A	2019	10	12	22	32	12	10	56	23	60	65	90	98
M01	Product A	2020	8	15	16	18	25	54	24	65	89	120	100	125
M02	Product B	2019	3	13	25	21	17	87	98	34	54	26	43	55
M02	Product B	2020	15	32	54	56	76	54	56	43	22	90	18	130

Then, I need generate a new row below each product with the Variation 2020 minus 2019 for each month.

Something like this:

I tried using a matrix, but it only make a sum of the values for each month, Is possible change it to generate a row with variation 2020 minus 2019?..

Thanks fot your help, It can help is very similar. but i am not an expert user.. Sorry!!. Is very complicated to modified the formula to generated the difference insted MIN/Max or AVE?

@gomezc73 - Put together a more concrete example for you with your data. The quick measure basically discusses the concept of how to do it, how to use HASONEVALUE, ISINSCOPE, etc. to find out where you are in the hierarchy/matrix and then you can decide how to do your calculation accordingly. See attached PBIX beneath sig. Page 6, Table (6), Measure 6.

Measure 6 = 
    VAR __productcode = MAX([product code])
    VAR __description = MAX([description])
    VAR __year = MAX([year])
    VAR __Month = MAX([Attribute])
    VAR __2019 = SUMX(FILTER(ALL('Table (6)'),[product code]=__productcode && [description]=__description && [Attribute]=__Month && [year]=2019),[Value])
    VAR __2020 = SUMX(FILTER(ALL('Table (6)'),[product code]=__productcode && [description]=__description && [Attribute]=__Month && [year]=2020),[Value])
RETURN
    IF(ISINSCOPE([year]),SUM([Value]),__2020 - __2019)
