To distribute expenses in a report to more than one account combination, use allocation. The best practice is to add all expenses to a report and then allocate the report total to the desired account combinations

• On the Details menu in the Expense list of a report, select Allocation.
• Select all expenses and click Allocate Selected Expenses.
• On the right side of the screen, add an allocation row for each account combination to be charged.
• Allocation can be done by percentage or by dollar amounts using the "Allocate By" menu to select either Percentage or Amount.

For more details on this process, review the Allocate Expenses documentation available from the Allocation and X-coding section of the Documentation page.
