I have document numbers (doc#) in this format 5298T800. The 5298 changes each day, julian date. The last 2 digits go from 00 to 99 for each document. I have a column with these document numbers assigned to each order I make. I would like at the top of that column to know which document number would be next. So basically it should find the highest doc# and tell me what the next number should be, i.e. 5289T801. The julian date doesn't need to change unless you know how to program it. It will need to start over at zero when it gets to 99.
