Retrospective Price Correction:

We require the ability to change the price charged to a customer for a transaction / en-mass e.g. when an error is made, or where a rebate payment retrospectively becomes a Gate Fee or vice versa due to the timing of a rise and fall calculation. See also Automation of Customer Invoices and Reports BRD and Rebate Structure and Updates.In this scenario, during the month the customer would have an estimated price entered against their contract. Transactions would be processed (Sales Orders, Billing Docs etc would be raised as normal). At a later date when the corrected price is known and updated against the customer contract, an adjustment would be processed from a custom SAP transaction.To-be Proposed solution from TechM is as below:Retro-BillingRetro-billing is a process of issuing credit or debit memos (Adjustment documents) for retroactive price adjustmentsStep1: Conditon record is uploaded by tool with price 100 AUD with valadity period 01.02.2015 to 31.12.999.
