Dear Team,

In my REDCap project, record IDs were previously simple sequential numbers (e.g., 1, 2, 3 … 149). After enabling Data Access Groups, the format changed to values like 149-1 and 149-2.

Is this the expected behavior of REDCap, or could it be due to a configuration issue?

Thank you,
Yetsedaw

Hi Yetsedaw,

I've seen that format of record IDs when you enable double data entry. 

Might want to check that setting.
