Dynamic measure or calculation to get new, old or drop based on previous year/quarter/month

[Anonymous]

Could you please help me to solve the below problem. It is getting tough for me to come to conclusion on choosing the path to solve below.

Requirement

The sales of a Material are categorized over a period-by-period comparison and the actual status is determined for the current period

The following categorization is required. This comparison can be between years or quarters or months

Problem Statement

This comparison should be dynamic between years, quarters and months and the above comparisons should be built dynamically on the fly

Material Code	2020	2021	Measure
abc		30	new
xyz	15		drop
sss	15	16	existing

Hi, @Anonymous 

Try this:

Measure = 
var _pre=Not(ISBLANK(SELECTEDVALUE('Table'[2020])))
var _current=Not(ISBLANK(SELECTEDVALUE('Table'[2021])))

var _if=IF(_pre=TRUE()&&_current=TRUE(),"existing",IF(_pre=TRUE()&&_current=FALSE(),"drop","new"))
return _if

Result:

Custom time-related calculations:

Sales YOY :=
VAR ValueCurrentPeriod = [Sales Amount]
VAR ValuePreviousPeriod = [Sales PY]
VAR Result =
    IF (
        NOT ISBLANK ( ValueCurrentPeriod )
            && NOT ISBLANK ( ValuePreviousPeriod ),
        ValueCurrentPeriod - ValuePreviousPeriod
    )
RETURN
    Result

Sales MOM :=
VAR ValueCurrentPeriod = [Sales Amount]
VAR ValuePreviousPeriod = [Sales PM]
VAR Result =
    IF (
        NOT ISBLANK ( ValueCurrentPeriod )
            && NOT ISBLANK ( ValuePreviousPeriod ),
        ValueCurrentPeriod - ValuePreviousPeriod
    )
RETURN
    Result

If the above doesn't work for you, please consider sharing more details about it and posting expected result so it is clear on what needs to be implemented?  And It would be great if there is a sample file without any sesentive information here.It makes it easier to give you a solution.

Thank you so much @v-angzheng-msft  for your response.

Here the material name that I'm looking for is in same table. And the year must be picked up from the date.
I will try to implement in the same manner as you suggested.

Familiarize yourself with the DAX functions EXCEPT() and INTERSECT() and use these in your measures.
