I have a solution that numbers the records in the invoice table with a serial number.

Example Invoice numbers 1224, 1225, 1226....

I also have a related workorder table I would like those records to be numberd with the invoice it is related to plus a letter.

Example Workorder numbers 1224-A, 1224-B, 1225-A, 1226-A, 1226B, 1226C...

Any ideas of how I can acomplish this?

Try the attached file on for size. The one issue was that i couldn't find a character code function so i just used substitute instead.

It utilizes the max() function, check it out, if you have trouble pulling it apart, yell.

You might also opt to use the choose function instead of substitute.

I think this is exactly what I was looking for!

I am still trying to figure it out, but thanks a ton!!!!

Genx, I have used your example file to implement this into my system and it is working beautifully!

Thanks for the great file!
