Calculate production - investment only for the first year

[OscarSuarez10]

Hello I need to calculate the difference between production and Investment but only for the year In which the production starts, that means that Production > 0, using DAX like in the following table, can you help me?

Product	Year	Production	Production - Investment	Investment
A	1	100	-600	700
A	2	50	50
A	3	20	20
B	1	0	0
B	2	500	-200
B	3	400	400
C	1	0	0
C	2	100	-600
C	2	789	798

Should be something along the lines of:

Investment = IF([Production]<=0,BLANK(),[Production] - [Production Investment])
