How to engage Lead Management & Channel Closed Loop?

While this is not my expertise, I am working with a client and would like to know a bit more about engaging the Channel and gaining adoption of your closed loop process with your partners.

This seems to be a common issue in the Tech space (past employer was a the 3rd largest PC maker and same issue)...how do you get partners to populate end-user data, lead status, etc. As we are developing a new end to end process for effective global lead management, we start to run into issues when we hit the channel.

SI's, Disty's, Mom and Pops. - There are a number of routes to market. All of them have various OEM's and such asking them to update their systems. None of these folks are going learn them all and initial thought is deeper discounts, money makes it happen.

In order to get pristine data on your marketing ROI or Channel Program, you need to report on leads/Oppty's passed to the partners. Assume Salesforce in-house...how do you close the loop on closed (win/loss)?

Seeiing any nuances across Geographies...EMEA and APAC are very channel heavy.
