Good morning everyone ,
I would like to suggest unique case ID within the device not the server side to prevent an enumerator to enter a Form twice or more concerning the same subject.
I implemented such a feature using instance name while entering data with enketo. After data entry , the enumerator saves the Form in draft. If there was already the same instance name, it indicates and the Form can’t be save with that instance name.
This is done After data entry while it would be better to check the instance name AT the beginning of data entry
Thank you
