Content

In our scenario, we have shared services where expenditure organizations are available for all LE’s under the same business unit and client wants to use IC solution in PPM to bill other LE. Any help will be highly appreciated. Even if this can be done outside PPM but updated in project contracts automatically that should be fine.
