I?m creating a project number tracking app which uses a unique project number. The project number format is YY-MM-SSS, where YY is the current year, MM is the current month, and SSS is a sequential project number. I?ve tried using a formula-text field type, to concatenate the Today () function and the Record ID# field to create the project number but I get an error message. I would like for the formula to build the unique project number with the current YY and MM components and roll over the sequential number back to 001 monthly. Can you help me? Thanks.
