Add calculated item to a Matrix

Hi carloscabreraq

There is no direct way in Power BI to achieve this requirment.

Here is a workaround

1.Create a new table with the same structure as your "transaccion" table,

This is to say, the new table has the same numbers of columns and the same column names, but only keep two rows and let the cells filled with 0 except the [tipo] column.

I create this table using Excel:

Copy the whole "transaccion" table, then paste in the Excel, 

delete all rows from this table in Excel, but keep the column header,

fill "e","f" in the [tipo] column as above, fill 0 in other cells (only create two rows)

2. import created table above into Power BI, the append this table to "transaccion" table in Power Query

Open Queries editor,

in "transaccion" table, select Home->"Append", 

then Close&&Apply, go to Report view

3. create measures based on the three measures

Last Month1 =
VAR sub_e =
    CALCULATE ( [Last Month], FILTER ( ALL ( transaccion ), [tipo] = "d" ) )
        - CALCULATE ( [Last Month], FILTER ( ALL ( transaccion ), [tipo] = "c" ) )
VAR sub_f =
    CALCULATE ( [Last Month], FILTER ( ALL ( transaccion ), [tipo] = "a" ) )
        + sub_e
RETURN
    SWITCH ( MAX ( [tipo] ), "e", sub_e, "f", sub_f, [Last Month] )

Last MTD1 =
VAR sub_e =
    CALCULATE ( [Last MTD], FILTER ( ALL ( transaccion ), [tipo] = "d" ) )
        - CALCULATE ( [Last MTD], FILTER ( ALL ( transaccion ), [tipo] = "c" ) )
VAR sub_f =
    CALCULATE ( [Last MTD], FILTER ( ALL ( transaccion ), [tipo] = "a" ) )
        + sub_e
RETURN
    SWITCH ( MAX ( [tipo] ), "e", sub_e, "f", sub_f, [Last MTD] )


MTD1 =
VAR sub_e =
    CALCULATE ( [MTD], FILTER ( ALL ( transaccion ), [tipo] = "d" ) )
        - CALCULATE ( [MTD], FILTER ( ALL ( transaccion ), [tipo] = "c" ) )
VAR sub_f =
    CALCULATE ( [MTD], FILTER ( ALL ( transaccion ), [tipo] = "a" ) )
        + sub_e
RETURN
    SWITCH ( MAX ( [tipo] ), "e", sub_e, "f", sub_f, [MTD] )

Hi carloscabreraq

To let this measure work with slicer, change "ALL"to "ALLSELECTED".
