Accrual Accounts

We have a significant number of inventory organizations and at month period, the reconciliation of accrued liability is becoming an issue since the accrual accounts hits only one account.  For better control and ease of reconciliation we are thinking of creating distinct accrual accounts one for each inventory org.

What are the potential issues if we make these changes.

1.  What will happen to the list of receiving transactions which have already accrued when new accrual accounts are created and payables invoices are matched to receipts from accounting respective.

2. How accounting will be generated for new receiving transactions against the currently Open POs.
