MC+E Display data as per billing Header (Cross Division)

Dear Gurus,

I have five divisions material in the billing document, and I am using cross division sales, at header of order and billing following sales area is coming

1000+10+10

and item level "Item Detail" tab page "Billing Data" all the divisions are coming on individual line items.

division 10

division 20

division 30

division 40

division 50

lets say the net value of each item is SAR 1000 for division 10, SAR 1000 for division 20, SAR 1000 for division 30, SAR 1000 for division 40, SAR 1000 for division 50,

while i am saving billing document and run the report system shows the correct value SAR 5000, but when I drill down the report on division level, it accumulate all the values on first division that is in the header of order or billing document division 10 SAR 5000, and all other will remain blank with zero value.

Please correct me where I make some mistake, or need correction
