IRE - Exact lookup count and Discovery source

[Balram3]

Hello All,

May i know in identification rule, what is exact use of exact lookup count ?

we wanted to use ire on custom table which is maintained by integration, import, and flow via request. to use reconciliation rule, do we have to create new choice in discovery source?

Thanks

@Balram3  the Exact lookup count requires that all provided cmdb_serial_number values must correspond to the same CI for a match to occur. For example, if item1 includes two lookup items, SN1 and SN2, will map to CI1 and item2 contains SN2 and SN3, then these values would map to CI2.

To apply reconciliation rules to an integration that imports data, the same discovery source used by the integration must be specified when setting up the reconciliation rules.
