Real Estate "Permanent Invoices" (Dauerrechnung)
I am doing the implementation of RE in Germay and after the business analysis an interesting requirement came up: the invoices related to rental agreements shall only be issued when the financial conditions change (and not acording to FI documents produced by the debit position). For example: for a contract with a monthly rent of 1000, an invoice (so-called "permanent invoice") shall be issued at the beginning and a new one shall only be issued when this monthly rent changes.
Being it a German requirement (and apparently quite common) I thought that SAP would offer a standard functionality to address it. Unfortunately I have been searching for quite a long time and didn't find anything.
Can anyone help me on this issue?
