GBS Service Center:

1. Processes all cycles, based on a pre-defined order for each entity. Processing includes the dealing with the generated messages.
2. Clarifies the reason for the messages, looks for modifications if possible, starts again cycles if needed. In case an error blocks further processing and it cannot be solved by GBS, the issue must be communicated to the Local Finance. After a solution is provided, GBS acts by launching again the related transactions and checks if the involved cost centers are balanced.

Local Finance:

1. Will contribute to find the solutions for occurring problems, above all caused by serious errors which cannot be solved by GBS.
2. Checks the outcome of cycles, i.e. the coherence, plausibility, reasonability of the generated cost allocation.
3. Gives the final approval to continue with the chronological next steps.
