I've got a billing statement in CR XI R2 where I'm showing the client invoice data in Detail band A, payment/adjustment info in Detail band B.  Both detail bands have an "INVNO" (invoice number) field.  I have both INVNO fields set to suppress duplicates.  I have to have the INVNO in both bands because there are companies with only payment info, no invoice info, and they need to see which invoice the payment applies to.  Likewise I have invoices with no payment info. 

Thanks very much for the quick response.

I think the second idea of PreviousValue() should work. What I would do is actually PRINT the PreviousValue() function in Details B just to see what value it is returning. That might clear up why it always prints. Once you see the actual data that is being compared, things will probably make more sense. It's probably something simple that you're missing and you'll have one of those "ah ha!" moments when you look at the raw data.

Secondly, what is "Object Name" and why do you think this will help? Somehow, I don't think I've ever seen this before and I'm a bit curious as to how I missed this "Object Name" property.

Another question, what is the Group field? Can you just put the InvNo at the bottom of the Group Header section so that it only prints one time? Ok, here is one more idea: Create a new Details A section (shift the other ones down) and ONLY put the InvNo field in it. Then set the Suppress formula to be PreviousField() on the grouping field. That way the InvNo only prints for the first record in that group.

One of these ideas should get you going. Remember, when all else fails, print out all the data in your formulas in the section so that you can see what CR is doing behind the scenes (I even put the Suppress formula in its own formula just so I can print that out and test when it is True or False). Seeing raw data makes everything clear.
