How to set up an auto-incrementing sequential ID (100, 101, 102) across form submissions?

[sdhakad]

I have a numerical field called ID in my KoboToolbox form. I want this field to automatically increment by 1 for each new form submission. For example, if the previous submission has ID 10, the next submission should automatically have ID 101.

Please help how to set this up in KoboToolbox.

Thank you.

Welcome to the community, @sdhakad! This post discussed previously should help you solve your issue:

Automatic code generation (Creating unique SN or UID)

@jessicanon, maybe you could do it as outlined in the image shared below: In the survey tab of your XLSForm: [Image 1] Data entry screen as seen in Enketo: When nothing is entered [Image 2] Data entry screen as seen in Enketo: When the name is entered [Image 3] Data entry screen as seen in Enketo: Now for other entries, you will not need to enter anything [Image 4] Reference XLSForm: Last Saved.xlsx (10.0 KB)

Correct. last-saved is the best approach to this.

It is worth being aware last-saved is per-form only, so if you use it for a similar purpose in a different form, you will generate a separate independent sequence of auto-incrementing numbers… The only other alternative would be to use an custom external app on the Android device that generates unique ids, and use ex: external app intents to pull it into your form(s).
