Self Join using two query subjects. Cognos 8

[handpass]

Hi,
I have two query subjects that have the exact same table entries in each of them. For one of the entries I have a different filter value applied for each query.

QS1
BatchId
Parameter (Filterarameter=Volume)

QS2
BatchId
Parameter (Filterarameter=Height)

I now want to join these two query subjects together so that I can get a combination of the two results.

QS1 QS2
BatchId(1..1)_______(1..1)BatchId
Paramter Paramter


When I test this I don't get any results returned.
It's as if the filter value in each of the query subjects is being joined with an 'AND', and because the filter is on the same entry in both query subjects it means that it can't be two different values at the same time. I am modelling all of this in Framework manager.

Regards.

Hi,

Provided the data supports it, this should work as you expect. If you test the query subjects individually, can you confirm that you are getting the common BatchID values returned in each?
