Adding leading and trailing characters to measure

Hi Fusilier2 

Can you please try the below DAX?

I have just corrected the RETURN Part. (It should be formatted in text format.)

VAR KPI Incr good% % Total =
VAR Excl_Casuals_MOM =
IF(HR_data[Headcount Excl Casuals month on month] < 0, 1, 0)
VAR Apprentices_MOM =
IF(HR_data[Apprentices month on month] < 0, 1, 0)
VAR mytest = 12
VAR Total_MOM = Excl_Casuals_MOM + Apprentices_MOM
VAR Result = DIVIDE(Total_MOM, mytest)
RETURN
"(" & FORMAT(Result, "0%") & ")"


If this answers your questions, kindly accept it as a solution and give kudos.
