I have a dataset FiscalYearMonth which contains
Fiscalmonthyear
Fiscalmonthkey
I have also Parameters!FiscalYearMonth.Value
How can I get Fiscalmonthkey for
FiscalYearMonth parameter ? I tried the following expression but didn't work
=lookup(Fields!FiscalMonthYear.Value,Parameters!FiscalYearMonth.Value, Fields!FiscalMonthKey.Value, "FiscalYearMonth")
