Receipt Accrual - Period end

Hello,

I do have folowing question for the concurrent request Receipt Accruals - Period-End.

1) The Nov-15 period is open for AP(Payables) and PO. If I try to run the request Receipt Accrual - Period end, I cannot get any value for the Period parameter.

2) Once the Nov-15 period is closed for Payables the period name becomes available in Period parameter.

Can anyone please help me ?

Thanks
