Here is one way, .pbix file attached

Hi

you need a common Date table, to use  PREVIOUSMONTH

total =SUM (value)

value_percent =

   var a = SELECTEDVAUE (attribute)

return SWITCH (a,

                        "A", blank(),
                        "B", total / CALCULATE (total, REMOVEFILTER (attribute), attribute = "A", PREVIOUSMONTH (Date)),
                        "C", total / CALCULATE (total, REMOVEFILTER (attribute), attribute = "B", PREVIOUSMONTH (Date)),

                        blank() )

Creata Matrix with month and attribute like you show, and add "value_percent' as value
