the question is:
in my table I got report id and cause for the report
can I deny insert of a record by checking if there's already record with the same 2 parameters ?
No, you can not check values from other existing records in the same feature layer. You can only check existing records in a repeat table or layer in the same feature service, if you have added those related tables to your survey as a repeat. Then you can use calculation to check if those values have been added before and use constraints or relevant expressions to hide or show to the user, or warm them with a message.
Hi, no it is not possible if they are other features in the same feature layer, only if they are repeat records in the same parent layer, and all are loaded as part of editing via the Inbox and available in that survey record.
