Function documentationCalculation of the Payment Schedule


The payment schedule displays the concrete periods in a loan. This is the interest and repayment schedule that lists all payments in the fixed interest period, the composition of these payments, and the remaining balance.


To calculate the payment schedule, SAP Customer Relationship Management (SAP CRM) uses SAP NetWeaver Process Integration (SAP Netweaver PI) to execute a function in the connected loans management system.

For more information about an example configuration of the ContractOrigination and LoanContractOrigination business scenarios, see SAP Solution Manager.


  • You have made the settings necessary to connect SAP CRM to the external system.

    For more information, see Connection to External Systems Using CRM Middleware.

  • Action profiles are available for the loan products. You have assigned the actions to the action profiles; you use these actions to calculate the payment schedules.

  • The system calculates the payment schedule based on the following settings entered for the loan product:

    • Payment structure

    • Conditions

    • Dates

    For more information, see Configuration of the Payment Structure.

  • In the standard system, the actions you use to calculate payment schedules are integrated in the business transaction.

  • When you execute the action for calculating the payment schedule, SAP CRM transfers the settings for the payment structure, conditions, and date management to the connected loans management system via SAP NetWeaver PI.

    The loan-managing system calculates the current payment schedule and transfers the data back to SAP CRM via the XI interface.

    In the FS quotation, the system displays the payment schedule in the detail view of the loan item in the Payment Schedule area. The system saves the payment schedule.

  • You cannot make direct changes to the payment schedule. To correct a payment schedule, you change the settings for the payment structure or conditions and then trigger the calculation again.

  • If a quotation contains several loan items, and therefore several payment schedules, you can display an overall payment schedule. The overall payment schedule provides an overview of the payment schedules for the loan items.
