Mile stone billing with partial quantity.

Question

Hi,
We are facing problem in the milestone billing. we have scenario where we have payment terms (Ex: 10% advance, 70% on delivery, 10% on installation and remaining 10% on completion) with the materials having multiple quantity. Delivery will be in partial, so except the advance invoice all the remaining invoice require change in the billing quantity before billing, but in the system billing quantity showing in gray mode. After delivery also remaining (10% installation) also will be on different quantity i.e. actually installed at the site.
As per the law invoicing has to be done with in the 14 days of the installation of the work, once the installation over for partial quantity we required to do the invoice irrespective of the delivered quantity.
In the system if we do the invoice for the total quantity at the time advance after that we are unable to change the invoice quantity in the subsequent invoices.
Please suggest us how to make enable the billing quantity field in case of milestone billing.
Ex: let us say sales order is created for qty 10 with the value of 1,00,000.00 as payment terms as follows.
10% Advance, 70% on delivery, 10% on installation, 10% final completion.
First we have raised the 10% advance invoice using 1st milestone with the total quantity.
When we deliver, we deliver only partial quantity i.e. qty. 5, so we have to create the invoice for (50,000-5,000) Rs 45,000. But when we create the second invoice we are unable to change the billing quantity. Same way when we create the third invoice after installation we may have to bill for qty. 3 if only 3 machines are installed out of 5 delivered, so again we require the quantity change.
Regards,

hi
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.
