Service Offering Costing cost model

The specifications of the Service Offering Costing cost model are:

• IT shared service segment accounts are sourced from the IT shared service [itfm_shared_service] table.
• Service Offering segment accounts are sourced from the Service Offering [service_offering] table.
• IT Shared Service segment rolls up to the Service Offering segment. However, there are no default rollup overrides.
• All sub-buckets are spread equally to all accounts in IT Shared Services provided by the base system setup.
• There is no data source to this cost model, which means that you should enter the spend information directly into the model and not come from the general ledger. Using the general ledger as a source of spend information is an optional feature that you can configure. See Prerequisites to modify data source of a cost model for more information.
• The expenses are allocated from IT Shared Services segment to the Service Offering segment by Equal method of the base system. By default, the allocation setup provided in the Allocation Setup stage is Equal rollup method. You can configure the rollup method, if needed, to match your specific requirements.
