I have this expression that works bringing amount
sum({$<YearMonth_LayOut={"$(=$(vYearMonth))"}>} amount)
But it brings only actual year/month and I need to see the months till actual month not including it. So I change the expression to
sum({$<YearMonth_LayOut={"<$(=$(vYearMonth))"}>} amount) and it brings me nothing
vYearMonth has the result = 2019/07 and I have data for YearMonth_LayOut since last year
Any idea what is wrong in my expression please?
