Hi Daniel,
You can't do that with just one object, you'll have create more than that:
- Create Detail object (variable) for Q1.Sample Date (with merged object Tag Name as the Associated Dimension)
- Create Detail object (variable) for Q2.Begin Date (with merged object Tag Name as the Associated Dimension)
- Create Detail object (variable) for Q2.End Date (with merged object Tag Name as the associated Dimension)
- And finally, the Detail / Measure variable to calculate CPK limit (if you create it as a Detail object, select Tag Name as the Associated Dimension). Also, if you still get a multivalue error, add a function Sum() over the whole formula and see what happens, if CPK Limit is a number that has to be added, if not, add a Max() or Min() so it bring the max/min of those multiple values.
Try that and let us know.
Thanks,
