It will carry over to the next month. See below.
1. - Period Differences:
Weekly reports are based on the calendar week (Monday to Sunday), whereas the monthly financial report is based on the Apple fiscal calendar (i.e. you may not be comparing the exact same timeframe).
2 - Order Process Period:
Items purchased in iTunes may take a few days to settle (be paid) in our financial system, as such items sold in the last couple of days of a fiscal month (see apple fiscal calendar) may not be completely processed until the subsequent month (e.g. if you buy an App or song on iTunes you may not receive an invoice for a few days). The differences in timeframes between the two systems will not allow you to reconcile one to one on a monthly basis.
We are confident that over the life of an asset (App, Song, Album) the reports will be accurate (e.g if you put something on the store and sell it for a week and then remove it, your reports will reconcile over two months).
