If your agreement is split between many cost centers, you can handle it from within the system directly. First, ask your admin to enable cost center splits from ‘Admin Settings’. Then, activate "Cost Center Split" in the ADDITIONAL sheet.
Following this step, a separate Cost Center Split sheet opens to this agreement. Select the right cost centers and then the applied %-shares to each selected cost center.
Then, in all reporting and accounting, the system will split all the numbers into the number of cost centers you have selected.
