Hi Kaushik,

The table structure is same what i have posted,

I need to show the sum of price based on the month, First of all i have to find the month from the above table then calculte the sum of price what else the month is selected, if i transpose the table then that issue resolve but when we are creating the Table box that time, it's not possible to add the filed name such as Jan Price,Feb Price, and so on

So that I can't transpose the table, but in expression i have to pick the dynamic field based on the Month.

For Example:Sum("SelctedMonth" Price)

Hi,

If your data source is like the one which you posted, you can transpose it while loading it in Qlik using the Crosstable Function.

Hi,

But in Pivot we have the scroll bar only for the expression not for the whole table.

I would also suggest to use CROSSTABLE in your script to transform your table.

If you really don't want to do this, and you have another field with month values that match the first part of your above field names, you can try this when a single month is selected:

=Sum( [$(=MonthField&' Price')])

The dollar sign expansion needs to expand to a field name.

You were saying

"I want to show the Sum of price based on the month selection as well as show the table box in which the structure is same which is shown above."

So how do you select month?

If you need a new field, you can add a data island in your scenario (not using CROSSTABLE to transform your data):

// Monthfield for above suggested expression. Values need to match your table field names, first part.

LOAD * INLINE [

MonthField

Jan

Feb

March

April

May

June

July
