Check above threads and answers - I think this requirement is not correct and few users raised it with Service Now team and they suggested to change the Order as 100/200 so after reading every answers and all discussions i reached on this conclusion and task got completed.

We have a good video on Now Learning showing the enhancement of reconciliation rules in Paris where Precedence and Reconciliation rules were merged.

The rule is very simple, you have defined a reconciliation rule with two sources, meaning both are allowed to update records in the Windows class. The priority determines which is the authoritative truth, so if ServiceNow updates a record and the discovery source of the CI now displays ServiceNow, no other authorized discovery source with a higher priority order number is allowed to update the record. It is confusing as the lower order number has higher priority, but this is common with other lists in ServiceNow, so it is consistent across the platform (i.e. business rules). Any source with order 100 has higher priority than a source with order 200. 

Hope this helps.

I agree.  There should be some filtering but it works

[glenn_pinto]

The filtering so to speak takes place by defining the data source on the first tab of the wizard. You are choosing a data source to build the reconciliation rule with so there is no need to define a filter for the data source as well. The filter is used to maybe filter on a specific operating system or device of a specific manufacturer that the rule can be used for.
