Hi,
I have a little problem with CONCATENATE formula, “RU-14-10-001″, where RU=Revenue Unit, “14″=Year, “10″=Month and “001″=series number. Note that series number will reset every month.
A1=RU-14-10-001, if “B2″ is NOT blank then “A2″=RU-14-10-002. I want it to automatically assign a sequence number in Column “A” every time I Update Column “B”.
Please see attached excel file.
Thanks
