Symptom:
As per the IR logic of 'others' tab , if any of the items which are not fall under the below scenarios, then we will show in Others tab.
Reported items,
NotYetSupported,
Duplicate Item,
Items available under both  Collected and Manual,
SN collected as Both Chassis and Card

Conditions:
For any Child SN, if SNAS recommending  the parent SN. as per IR logic, we will omit the Child and will report the parent in the portal. So that is the reason this child will not be reported anywhere except Others tab

If we  take one SN, if that serial number is collected for two/more chassis/cards which are having different network element id. Among these chassis/cards, one chassis/card will be reported which is profiled and other will be reported under others tab.
