hiding columns in Matrix

Hi,

If you don't want to see particular column for different categories in the matrix then there is one solution.
For example, 

From the above matrix and I want to see only
Current FY -> Actual, Budget
May 2020 -> Actual
May 20201 -> Actual, Budget and Var

So, for this I have created one another table where I am taking only those columns which I want to see in the matrix. As shown below 

Categroy Table = 

You can make this table by just entering data and loading into the power bi. 

Next step is to create relationship between Sales table and Category table. 
My sales table has a calculated column named "FY Bucket". 

FY bucket =

SWITCH(TRUE(),

Sales[Month No] <= 5 && Sales[Year] = 2020,"MAY 2020",

Sales[Month No] <= 5 && Sales[Year] = 2021,"MAY 2021",

Sales[Month No] > 5 && Sales[Year] = 2021 || Sales[Year] = 2020 ,"Current FY","Others")

And now we will create the relationship between Category['FY'] & Sales['FY bucket']

Note that, as both table has multiple values in the column it will display Many to Many relationship only. 
To avoid many-to-many relationship you can create bridge table. 

Next step is calculating Actual, Budget and Var for corresponding columns. Here, I am creating measure for that, it's formula is given below. 

Sales Measure =

SWITCH(TRUE(),

SELECTEDVALUE('Category'[FY]) = "Current FY" && SELECTEDVALUE('Category'[Cal]) = "Actual",

CALCULATE(SUM(Sales[Actual]),

Sales[FY bucket] = "Current FY"),

SELECTEDVALUE('Category'[FY]) = "Current FY" && SELECTEDVALUE('Category'[Cal]) = "Budget",

CALCULATE(SUM(Sales[Budget]),

Sales[FY bucket] = "Current FY"),

SELECTEDVALUE('Category'[FY]) = "MAY 2020" && SELECTEDVALUE('Category'[Cal]) = "Actual",

CALCULATE(SUM(Sales[Actual]),

Sales[FY bucket] = "MAY 2020"),

 

SELECTEDVALUE('Category'[FY]) = "MAY 2021" && SELECTEDVALUE('Category'[Cal]) = "Actual",

CALCULATE(SUM(Sales[Actual]),

Sales[FY bucket] = "MAY 2021"),

SELECTEDVALUE('Category'[FY]) = "MAY 2021" && SELECTEDVALUE('Category'[Cal]) = "Budget",

CALCULATE(SUM(Sales[Budget]),

Sales[FY bucket] = "MAY 2021"),

SELECTEDVALUE('Category'[FY]) = "MAY 2021" && SELECTEDVALUE('Category'[Cal]) = "Var",

CALCULATE(SUM(Sales[Var]),

Sales[FY bucket] = "MAY 2021")

)

Put your measure as Values into the matrix. 
And here is the result:
