Hello All,

We have created an aggregation query builder and successfully aggregated it
through 'Aggregate and Save' button in 'Manual Person Aggregation'.

But while we are trying to see the value of aggregated data element through
the 'preview' in 'Manual Person Aggregation' it is showing exception error.

The screen shot for this exception error is given below.

Please help me.

Thanks
