Validation on not duplicate data

[ebm_2]

I need to validate that each form will be submitted only one time during the project so I did add the National Id in my from but there’s no stop duplicate future so is there’s any way to help dears , I guess this future will help a lot and make more people use your tool

@ebm_2, I have changed this post to a User Support post as we already have a new feature coming up shortly which should address your issue:

Dynamic data attachments

Lock selected choice

Seems like you have a sample frame and your team is collecting data in the field. If say sample 1 has already been collected and submitted to the server, the enumerator should not collect the data form sample 1 again. There should be some indications that sample 1 has already been collected? Is this what you are looking for?

I will update you when this feature goes live in KoBoToolbox.
