I am trying to build a matrix that compares the differences from one quarter to another - actual differences or percentage differences.
I have tried copying several examples without success. The examples use numeric values (e.g. Sales in USD), but the values I am using are not numeric, but strings (e.g. "Sales visit" or "Contract signed"). Therefore I cannot use SUM and have been trying with COUNT instead:
SupportTypeCount = COUNT(MyTable[Support type])
In the matrix the rows are the "Support types" and the columns are Quarters:
Quarter = FORMAT([Date], "\QQ yyyy")
So far, so good. But I cannot find the correct measure for the values - I have tried numerous combinations, also using a Date Calendar, but all have failed:
QuarterlySupportChange = DIVIDE(MyTable[SupportTypeCount], CALCULATE([SupportTypeCount], DATEADD('Date'[Date], -1,QUARTER)),0)-1
Supports LQ = CALCULATE([SupportTypeCount],DATEADD(MyTable[Date],-1,QUARTER))
Supports LQ = CALCULATE(COUNT(MyTable[Support type]),DATEADD('Date'[Date]-1,QUARTER))
Supports LQ = CALCULATE(COUNT(MyTable[Support type]),PREVIOUSQUARTER(MyTable[Date]))
Supports LQ = CALCULATE(COUNT(MyTable[Support type]),DATEADD(MyTable[Date],-1,QUARTER))
Any help pointing out my error will be very gratefully received!

Solved! Go to Solution.
@CJDK , with help from date table marked as date table , these should work
Supports LQ = CALCULATE(COUNT(MyTable[Support type]),DATEADD('Date'[Date]-1,QUARTER))
Supports LQ = CALCULATE(COUNT(MyTable[Support type]),datesqtd(DATEADD('Date'[Date]-1,QUARTER)))
Make sure the date table is marked as a date table, there is no timestamp in the fact/table table

Many thanks Amit - again! 🙏
Your video was very instructuve and I have been able to use that input and your corrections to springboard to my final measure:
QuarterlySupportChange = DIVIDE(COUNT(MyTable[Support type]), CALCULATE COUNT(MyTable[Support type]), DATEADD('Date'[Date], -1,QUARTER)),0)-1
Please note a missing comma in your measures:
'Date'[Date],
MANY thanks!
