Hi Jolene,
Did you use the merged CustNo in your table ?
It´s strange because you should see in the options for the associated dimension, the merged CustNo and the individuals one .
Did you, in the objects pane of the report, click on both CustNo and then click on merge dimensions (right click and choose merge) ?
Sorry to ask that, but we just want to make sure you merged the dims, because I´m in doubt.
Regards,
Rogerio
