Adhoc Reporting - DistinctCount issues

[DavidT_UK]

Hi,

I've got an adhoc report that lists orders from suppliers, but it's also listing duplicates (invoicing related).  There is an option in custom expressions for this, but it doesn't seem to be working.

When I use command CountDistinct("Order Reference", 'Total') I'm getting an 'Aggregate expressions are not allowed in fields; please create a measure if you wish to use an aggregated expression'

I've tried it with several of the different options like RowTotal/RowGroup etc but its the same.   

Thoughts?

Hello David,

as the message is saying, you should try to define a new measure instead of a new field in order to use this calculated field.

You can find the measures list at the bottom left of the ad hoc editor and then click on the 3 points to add the new measure with the same expression you have been using already
