Hi,

I hear lot of different answers.,

Can someone tell me the exact use of Singleton with an example please.

Thanks!

A singleton is a data container that returns a single data item without anything else.  For example, lets say you have an executive summary report showing Revenue by quarter by division in a chart, but at the top of the report, they wanted a summary that just said:

Total Sales this Period: $5,456,000

A singleton will allow you to put the total sales number without showing any column headers or row headers.

Thanks for your response.

Single value means it will show the top value? or is it possible to add two data item in one singleton?

[tjohnson3050]

The top value, and it will only show a single value, not two.

Hi..sorry I am still not clear .sorry to be silly.

Singleton will just display the top value of a data item?

Ex": I have a data item Sales, when I add this sales data item to singleton will it display only the top value.

The singleton is meant to return a dataset of 1 dataitem and 1 value only, but it's definition should be exact to control the outcome. Total sales of a certain period fits the bill; only 1 value is ever returned..
