Exclusion item condition value for header condition

Question

Dear All,
I explained my problem with example scenerio.
Sales Order Total Net Amount = 1.500 EUR
SO Item-10 = Advance Payment Sales = 500 EUR >> for first invoice
SO Item-20 = Sales from stock with HAWA material - 1 = 300 EUR  >> for second invoice
SO Item-30 = Sales from stock with HAWA material - 2 = 1.200 EUR >> for second invoice
SO Header condition > ZAP1 = Advance payment decrease = - 500 EUR
System divided Advance Payment amount to all items.
Item-10 = - 125 EUR
Item-20 = -   75 EUR
Item-30 =  -300 EUR
My request is on below;
Item-10 =      0 EUR
Item-20 = - 100 EUR
Item-30 = - 400 EUR
Is calculation possible with zero value for item-10 ?
Thanks for your helps.

Hi Gulay
System cant divide the advance payment to all items ,System can divide the advance payment for one item  .
But assign a billing plan at header level and just check , if it works then your requirement can be fulfilled.But generally it is done at item level only 
                        Make the following down payment configurations
item category group - 0005
item category - TAO
for this TAO item category a billing plan 01 (milestone billing plan -01) will be assigned and its billing relevance should be I which is order related billing .
billing doc type - FAZ
cancellation billing doc type - FAS
maintain a condition type AZWR which is down payment settlement , it has requirement as 2 and calc type as 48 acct key as ERL
Now when you enter a material in line item 10 and go to item data , you can see the billing plan tab.
now go to billing plan tab and enter the start date and enter the dates on which billing has to be done and then in billing request enter 0009 which is for down payment.once u press enter automatically it all the dates get blocked and billing request by default you get as 1 , that you change it to 4 or 5 . 4 is for down payment at value basis and 5 is for down payment at percentage basis. and beside that there will be a billing type .assign billing doc type as FAZ. to all dates
check the copying requirements are there at VTFA as 20 and for item category TAO copying requirements 23 is maintained or not
now do the cycle OR - LF - FAZ (billing doc type)
