Receipt accrual interface to PA

 Hello,

For setup Expense Items = 'Accrue at receipt', is it okay if I do not interface Receipt accruals to PA? Is this a correct business practice? What problems would I probably face in this case?

I tested not interfacing receipt accruals to PA - I found out that the receipt lines are showing up as exceptions in the EXC: Transaction Exceptions Report. Once I create invoices and interface them, the exception lines are not showing up. Is this a standard functionality? If yes, it would cause problems in period close for uninvoiced receipts. Please advise

Thanks!
