Duplicate task for scanner table in CMDB

[Appy2]

Hi Team,

can anyone tell how we can enable duplicate task creation for tables like Printer,Scanner etc?  As in the system i can see duplicate task is being created only for few CMDB tables (Refer below screenshot).

Deduplication tasks are created only if duplicate records are present in that CI class. The duplicate records will be considered based on the attributes present as identifier entries in the identification rules applicable for that class. You can check my article below for more information about identification rules:
