Hi,
Need some help here. I have a list of sales closes. The rule is that the sale cannot be closed more than once within 90 days. I know how to identify if the close is listed twice using an sum product formula. However I wonder if I could add the 90 day criteria. See my attached example.
You see I can identify the unique closes using formula by giving it a value of 1. But it won’t distinguish if the close was previously closed within 90 days.
Any suggestions?![]()
