Calculated Column akin to COUNTIF

[jl20]

Hi,

I am trying to figure out a formula for a calculated column that will count the number of instances of a MatterID number (i.e., the red text in the screenshot below). Every "D" is on the table one time. Then, if the job becomes active, a new "E" record is created with the same MatterID. I searched the forum and could only find examples where multiple tables were involved.

This seems like it should be easy, but I can't seem to figure it out. Thank you in advance for your help.

A calculated column like this should to the trick:

=
CALCULATE ( 
    COUNTROWS ( YourTable ),
    ALLEXCEPT ( YourTable, YourTable[MatterID] )
)

That worked, thanks for the quick reply! How would I modify so that if MatterID is blank, it returns a zero?

To handle that, just wrap the original measure in an IF ISBLANK test:

=
IF (
    ISBLANK ( YourTable[MatterID] ),
    0,
    CALCULATE (
        COUNTROWS ( YourTable ),
        ALLEXCEPT ( YourTable, YourTable[MatterID] )
    )
)

Perfect, thanks
