You can however work on your own off-system approaches to avoid duplication by first narrowing your definition of “what is a duplicate”. You can then try advanced approaches, which do ex=post checks for duplicates such as what was discussed in the topic below

Avoiding duplicate records

Hi Marcelo, The server does not check for those kind of duplicates, once a record is saved, a unique _uuid is created, which is used to avoid duplicates on submission. For your case, maybe you can create a concat instance field, used to save the form, under settings sheet, you can add a new column (instance_name) then enter concat(string(today()),’-’,’${date},’-’,${site}), so each submission will have this as its default name. When you export the data in either csv/excel, there’ll be this colu…
