I have the following scenario as part of the Business requirement, please suggest me how to map this in SAP
A company sells products on the basis of a price. The agreement is that billing will happen on the basis of previous monthu2019s price, in the current month. On the first of every month the new price is declared. On the second of the month, after the new price is declared, the company calculates the difference on every invoice and needs to send debit memos and credit memos for the difference of the price between current month and last month. This should happen automatically and not on a invoice by invoice basis manually. In other words in one run all the debit memos and credit memos should get generated.
Thanks in advance
