Hi,
This is a question regarding the payment scheme functionality on a SAP IS-U system
Scenario
We are working on a billing system for a utility company in the energy sector. Customers may have one account but 2 contracts (elec and gas). Currently we use the payment scheme to calculate the projected cost for the next year and create the customer's monthly payment plan at contract level. As the cost is estimated there are variances for each contract at the end of year and they may result that one is overpaid and another is underpaid. Currently, the reassessment works at contract level carrying the debt over the next period. Moreover, if the customer has done a payment outside the scheme, that gets posted at contract account level and ignored by the reassessment.
Question
In order to improve the reassessment and include all documents we are thinking on using the standard clearing run during the invoicing processing to clean up the account and then use the resulting balance prorated on each contract to calculate the next periods charges.
My question is: is there any alternative functionality that enables us to include items outside the contract during the generation of the payment scheme?
Thank you very much,
Josep Coll Piferrer
