Forum Post: RE: How to Create a Crystal Report based on a Union Query for SO_InvoiceHeader + SO_InvoiceDetail to AR_InvoiceHistoryHeader + AR_InvoiceHistoryDetail

I have checked the data and there is no corrupt date fields and am only selecting the data where the date is within 1 year of today.  I have checked every field and the queries that I am trying to unite have correct data in all of them.  I don't know where to go from here.  I'm stumped.
