I thought I know Crystal pretty well and now I am finding I don't! I have a client that wants what appears to be a simple report but I am having problems getting it to work. They want a report that shows PO#, Job#, Required Date, Received Date and then a flag if the Received Date is greater than the Required Date. Report works great until I add Received Date. When I add that field, any PO without a Received Date falls off the report. I thought about adding the Received date to a subreport but I don't think I can make the date comparison if both dates aren't on the same report. I'm using PO_PurchaseOrderDetail and PO_ReceiptHistoryHeader. Ideas?
