Dear Kamal,
Consider you have two domains abc.com and xyz.com : Both have local report suites ABC and XYZ with global report suite GBL.
Consider customer enters your abc.com site via Facebook, navigated two pages in abc.com and moved to xyz.com to submit Lead Event after 3 pages.
In ABC Report Suite, Social Network (Last Touch Channel : Because the referrer is Facebook) will have two pageviews but not Lead Event.
In XYZ Report Suite, Internal Traffic (Last Touch Channel, if you have set up internal traffic properly : Because the referrer is abc.com) will have 3 Page Views and Lead Event. Referrer facebook will not be passed from ABC report suite to XYZ report suite since they are local.
In GBL Report Suite, Social Network will have 5 Page Views(2 in abc.com and 3 in xyz.com) and Lead Count. Since it is global report suite, referrer will persist.
So, it it clear that Last Touch Channel in Local Suites will not have same contirbution as Global Suites. Kindly dont compare the same!
Thank You!
Arun
