display the common value based on active and comparison selection

[settu_periasamy]

I have the selection field like the above.

Act. YearMonth = Active Year Month

Comparision Year Month = Assigned to one variable (vComparision_selection).

Mel(Key) or Mel - Display value (List box).

I need the expression in the list box to display the Mel(Key) which is active in both the Active and comparison (Like intersection).

Thank you in advance.

Use the following Exp.

SUM({$<ComparisonYearMonth=P(Act.YearMonth),Act.YearMonth=>} MEL)

[settu_periasamy]

I have variable for comparison part only(vcomparisonselection) not for active year month.

and MEL is the string. Just i need to display the common MEL in active year month and comparison yearmonth.

hope, this would be clear.

I need the MEL which is common in based on the below selection.

in the below example, if the MEL is there in Act.YearMonth(201308) and comparison YearMonth(201208), it will display based on the expression.

comparion YearMonth variable - vComparisonSelection.
