PO Receipt not transferred to Projects

HI

We have a PO receipt that has not been transferred to PA.

In the rcv_transactions table , the PA_ADDITION_FLAG is null , PROJECT_ID is entered , REQUEST_ID is O

In the rcv_receiving_sub_ledger table , the PA_ADDITION_FLAG is null

There is no trace in the PA_TXN_INTERFACE_AUDIT_ALL table

select

*

from

PA_TXN_INTERFACE_AUDIT_ALL

where ORIG_TRANSACTION_REFERENCE=:rcv_transactions.transaction_id

Any ideas, thanks

John
