Billing of Order/Contract

Question

Hi SD Guru's,
I have a scenario wherein my contract period is from say 01.10.2007 to 31.10.2007. (say monthly price is 3000, and calendar days are set to 30). This contract is created for an agency. Now i create a sales order for a particular client in reference to this contract from say 15.10.2007 to 31.10.2007. Now i want to bill the agency for 15 days (from 01.10.2007 to 14.10.2007) directly from the contract and the client from (15.10.2007 to 31.10.2007) against the sales order. How can i take care of this scenario in SD?
Waiting for your replies.
Thanks and Regards
Ravi

Hi Ravi
U can do this by Period billing or Milestone billing.
<b>Billing Plan for Milestone Billing</b>:
Milestone billing means distributing the total amount to be billed over multiple billing  dates in the billing plan.
As each milestone is successfully reached, the customer is billed either a percentage of the entire project cost or simply a pre-defined amount.
During sales order processing, the system determines from the item category whether a billing plan is required and, if so, which type of plan
The type of billing plan that is determined at this point is set up in Customizing and cannot be changed in the sales document.
Billing plans for periodic billing and milestone billing plans for project-related milestone billing have different overview screens so that you can enter data relevant to your processing.
For example, for milestone billing, you must be able to enter data to identify the
individual milestones.
IMG configuration requires :-
1.  Maintain billing plan types for milestone billing in OVBO.
2.  Define date description in SM30 - V_TVTB.
3.  Maintain Date Category for Billing Plan Type IN OVBJ.
4.  Allocate date category in SM30 - V_TFPLA_TY.
5.  Maintain date proposal for Billing Plan Type in OVBM.
6.  Assign Billing Plan Type to Sales Documents Type in OVBP.
7.  Assign Billing Plan Type to Item Categories in OVBR.
8.  Define rules for determining the date in OVBS.
Milestone billing is typically used for billing projects, such as plant engineering and
construction projects. Such projects often include a series of milestones that mark the
completion of different stages of the work. In the SAP R/3 System, milestones are defined
in a network along with planned and actual dates for the completion of work. The milestones
are also assigned to the billing dates in the billing plan.
Each milestone-related billing date is blocked for processing until the Project System
confirms that the milestone is completed.
Delivery-relevant order items for which a milestone billing plan applies are billed on the
basis of the requested delivery quantity and not on the total of the confirmed quantities.
The connection between the project and the sales document item is made in the individual
schedule lines of the item. Each schedule item can be assigned to a network in a project.
To display the project-related data for a schedule line, proceed as follows:
In one of the overview screens of the sales document, select
1.  Item -> Schedule lines.
2.  Mark the schedule line and select Procurement details.
The following figure shows an example of milestone billing where only the Contract have
been billed :
Order  Item  Turbine    100,000
Billing Plan
Billing date Description    %  Value  Billing Block   Milestone   Billing Status
01-10-94     Contract      10  10,000      -             x           x 
01-03-95     Assembly      30  30,000      x             x          
01-04-95     Maintenance   30  30,000      x             x
01-05-95     Acceptance    30  30,000      x             x
01-06-95     Final invoice ..    ..        x
Network/Activities
Milestone    Estimate      Actual
Assembly     01-03-95      01-03-95
Maintenance  01-04-95     
Acceptance   01-05-95
For each billing date in a milestone billing plan, you can specify whether the billing
date is:
1.  fixed
2.  always updated with the actual date of the milestone
3.  updated with the actual date of the milestone, if the date is earlier than the
    planned billing date for the date
