In your SAP Solution, the Cross-Catalog Mapping (CCM) in the SAP Sales Order Management (SOM) system defines which allowances must be created when end customers sign contracts for a subscription product or when changes are made to the customers' contract. SAP SOM creates allowances in the SAP Convergent Charging system, on demand or automatically, when the SAP Convergent Charging provider contract is activated or changed.
SAP SOM sends a charging operation request to SAP Convergent Charging with an ALLO chargeable item (1). This specialized chargeable item contains the identifier of the allowance definition to be created, and the date/time at which the allowance must be activated.
SAP Convergent Charging processes this charging request, and identifies and executes the relating contracted charge (2) in this contract.
This charge retrieves the corresponding allowance definition from the allowance definition table, creates the corresponding allowance, and initializes the allowance according to the allowance definition (3).
The charge can generate billable items for reporting purposes (4), and the allowance can generate billable items for deferred revenue recognition purposes (4).
