Using calculated dimension that uses a variable to determine one of the columns required in a pivot report..

Hi all,

I am facing a peculiar problem when using a calculated dimension in a pivot report. (on QV version 8.5 and 9.0)

I am making use of a variable that would determine what dimension field the report should use. e.g. =$(vDimLevel)

Everything works well, the report gets populated with the required dimension values, untill I click on the "CLEAR" button. I get a runtime error and I have to close the program.

When I add the same dimension explicitly, there is no problem with the data or its refresh.

Suggestions/ help is most appreciated and also required urgently 🙂

Thanks much!!

Hi,

I d'ont understand what you're trying to do, the user have to write the name of the dimension he wants ?

Why not using a Group with different possible dimension to choose the dimension ?

Try using

=[$(vDimLevel)]

Just a thought: May be when you click on clear it clears the value in the variable also and you end up having a chart without a dimension which I guess is not possible to have and leading to the runtime error.

Thanks folks for responding so quickly!!

Amit, you hit the nail on the head!!

Ofcourse the variable was pointing to a selected data field, and it would have no value when selections were cleared up.

BUT now I am struggling to get the condition working for the calculated dimension. I am trying to use another field to be used when "the" variable gets cleared up. The expression looks like,

=if(len('$(vDimLevel)')>0,$(vDimLevel),[Corporate]) when I use the field name itself

=if(len('$(vDimLevel)')>0,$(vDimLevel),$(vCorporate)) when I use another variable which always points to field "Corporate" similar to $(vDimLevel)

NEITHER SEEMS TO BE WORKING!!

Any ideas on this one 🙂

Thanks again!!

Should have added. The $(vDimLevel) works but the [Corporate] / $(vCorporate) piece does not....

I'll ask a question that was asked previously...

Why can't you create a dimension group (either cyclic or drill-down) to be able to choose different dimensions? (Dimensions tab, Edit Groups button)

What you're explaining seems like a perfect place for a cyclic group.
