Maintaining Billing Plans for WBS Elements
Use
You use the billing plan to plan the dates on which payment requests or invoices affecting sales are sent to customers.
Prerequisites
If you want to maintain a billing plan for a WBS element, you must flag that WBS element as a billing element.
You must maintain a revenue element in the plan profile. The system records revenues and incoming payments under this revenue element.
If you want to use templates to create billing plans, go to Project System customizing and maintain a billing plan in the Maintain Billing Plan Type transaction.

The standard system we deliver contains billing plan type 31 as a template. You can create the billing plan template directly in the implementation guide or copy a billing plan already in the WBS element to act as your template. The template contains dates, percentages, and absolute amounts.
Procedure
The Billing Plan dialog box may appear. Choose a billing plan type and currency type and enter a target value.
This takes you to the screen for changing dates in the billing plan.
If you want to work with a template, enter the number of the relevant billing plan template in the Template field. You can have the system display all the templates you have maintained in Project System customizing.

You must always enter the template number as a ten-digit figure. For example, if the template number is 491, you must enter 0000000491 in the template field.
The system displays the dates and percentage apportionments, updated, in the billing plan. You can overwrite this data.
This brings you to the WBS maintenance screen.
This saves the billing plan too.
Result
The system determines the planned revenue and incoming payment data from the billing plan and updates it to the relevant WBS element. This takes place in plan version 0 and commercial transaction PSFP.
The revenue-relevant dates in the billing plan update the WBS element revenue plan periodically. Plan data is recorded under the revenue element for the plan profile given in the project definition. Down payment dates are not so recorded because they are not revenue-relevant.
If you have activated Project Cash Management, the billing plan data updates the WBS element financial budget daily, taking account of the payment terms entered for that date. .
See
Calculating the Payment Flow Automatically.
If you are working with a template, the system determines the dates and percentage distribution of amounts per that template. The system adapts the dates and percentage apportionments to the target date. If you change the start date, the billing dates are adjusted accordingly.

The advantage of working with templates is that the dates in the billing plan are adjusted automatically if the dates in the WBS change. Note that the dates in the billing plan are not updated until the WBS has been scheduled.
If you want to work with fixed dates, you must not use templates to create your billing plan.
