Multi Invoice for service SO!

Question

Dear SAP experts,
in the case of service SO (sell out these services), can we raise more than one invoice related to exist sale order?
eg:
- create 01 service Sale Order such as
       Line Item: Service 001 ; Qty 10 ; price 10 ( amt = 100 USD)
- how to separate into Invoice 1 with 60 USD and Invoice 2 with 40 USD
Can we have a option as the Billing Relevance = K(delivery-related invoice for partial quantity) in case of goods!
thanks for your suppors,
Viettq.

Dear Tran,
Your requirement can be met using Milestone building.
Please do the following configuration and check the results.
1.Define Billing Plan Types
PATH : SPRO IMGSALES AND DISTRIBUTIONBILLINGBILLING PLANDEFINE BILLING PLAN TYPES (T.Code- OVBO)  MAINTAIN BILLING PLAN TYPES FOR MILESTONE.
2.Define Date Descriptions
PATH : SPRO IMG SALES AND DISTRIBUTIONBILLINGBILLING PLANDEFINE DATE DESCRIPTIONS ( Give one as 60% date and other one as  40% date)
3.Define and Assign Date Categories
PATH : SPRO IMGSALES AND DISTRIBUTION BILLING BILLING PLANDEFINE AND ASSIGN DATE CATEGORIES
Here assign the milestone billing plan type to DATE CATEGORY 01 & 02
Also assign Billing rule 1 of the standard SAP R/3 System ('Percentage-based milestone billing')
4.Maintain Date Proposals for Billing Plan Types
PATH : SPRO IMG  SALES AND DISTRIBUTION  BILLING  BILLING PLANMAINTAIN DATE PROPOSALS FOR BILLING PLAN TYPES (T.Code : OVBM)
To maintain the date proposal for milestone billing, go to the detail screen of the date
proposal and select the function 'Maintain dates'.
When you create a billing plan with milestone billing, the dates are copied according to the
reference, re-determined on the basis of the current rules, and placed in the billing plan.
Mention the billing dates, date descriptions, % for each milestone & SET A BLOCK REASON if necessary.
5. Assign Billing Plan Types to Sales Document Types
PATH : SPRO  IMG  SALES AND DISTRIBUTION  BILLING  BILLING PLAN ASSIGN BILLING PLAN TYPES TO SALES DOCUMENT TYPES (T.Code : OVBP)
6. Billing Plan Types To Item Categories
PATH : SPRO IMG  SALES AND DISTRIBUTION  BILLING BILLING PLANASSIGN BILLING PLAN TYPES TO ITEM CATEGORIES (T.Code : OVBR)
Assign I and your billing plan type to item category.
7. Define Rules for Determining Dates
PATH : SPRO  IMG  SALES AND DISTRIBUTION  BILLING  BILLING PLANDEFINE RULES FOR DETERMINING DATES (T.Code : OVBS)
Please check after making the above configuration 
If the same is not acceptable for business, please revert back.
Thanks & Regards,
