Hi Perrine,
ône more question regarding the requirement: If you would now create three different user profiles (one to restrict selection to EHs with parameter 1 starting with 'A', one for EHs with parameter 1 starting with 'B' and one for EHs with parameter 1 NOT starting with 'A' or 'B'), would these three user profiles be assigned to different users? Or would it be also a use case that one user will have two or all three user profiles assigned?
Best regards, Daniel
