Period End Accrual

I need to write off all of my expense receipts to start the Period End accrual process.

We already did the setup during the beginning of the implementation but we never went through the period end accrual process.

No we need to activate the process but the problem is that when we run un-invoiced receipt report we got millions of dollars of un-invoiced receipts which is not true.

So we need to start this process for the GRN starting from beginning of next month and we need to cancel all un-invoiced receipts history.

Any ideas?
