Restart sequence from autonumber based on another field

[achamess]

I’m trying to automatically name experiments based on the user that performs them. The numbering is sequential. However, I want the numbering to relative to the user.

Here is the formula I’m currently using:

{Initials (from Owner)}&"_"&"EXP"&REPT(
    '0',
    4-LEN(
        {Autonumber}&''
        )
    )&
{Autonumber}

The issue is, I want that next experiment (MP_EXP0005) to start at MP_EXP0001, rather than 5. Is there a way to do that with a formula?

That’s a little tricky.

You’d probably want to create an automation that automatically triggers a custom JavaScript script, or you could use Integromat for a no-code way of handling that.

However, there is also a workaround that @Justin_Barrett created — it has a few limitations due to Airtable’s built-in limitations, but it should work, too.

All of these options are discussed in this thread:

Autonumber Projects Based on Customer and Project Type Formulas

I’m looking to use Airtable as a full project management solution for my company. But one of the requirements is that projects must adhere to a certain project numbering convention: XXXX-0000-X XXXX is a 4-letter code, specific to each of our clients (1000+) 0000 is a 4-digit number, which auto-increments starting at 0001 for each client (not globally, each client counts up) X is one letter, based on the project type Our current system generates this number automatically upon entering a ne…
