Accounting Program Error - oracle

Question

I have Oracle Application R12 running on 11g.
The error occurs in Accounting Program when we are running Create Accounting session in Payable Module.
When we click on Diagnostics it gives this message :
This request finished with an error and produced the following
completion message: An internal error occurred. Please inform your
system administrator or support representative that:
An internal error has occurred in the program
xla_ap_acct_hooks_pkg.main. Technical problem : Error encountered in
product API for extrac
The processing began on 24-MAR-2015 09:11:13
and ended on 24-MAR-2015 09:12:16. You may find more information on
the cause of the error in the request log or the concurrent manager
log.
and if we click on View log it gives this :

Answer 1

Referencing MOS Doc ID 1964046.1 it appears as though you will need a patch.
Note: While it is typically SO best practice to include quotes from whatever source you are linking it is actually violating the ToS with Oracle to quote their MOS documentation. I like my support contract, TYVM.
Also there could be an issue with this, please reference MOS Doc ID 1582378.1 :
*************************************************************************************************** The following REVERSAL events could not be processed. The
event/process status is U/U: Note: this warning may be ignored for any
events whose ledger is a cash-basis ledger -------NO SUCH
EVENTS-----------
If this is a production environment I highly recommend opening an SR to confirm that this is the only issue you are seeing.

Answer 2

It could be because of the following reason.
There is some orphan record exists in xla_transaction_entities table. Delete those lines from the table. It will be Ok. To identify the record, you can use the below query:
SELECT *
FROM xla.xla_transaction_entities xla_tran_ent
WHERE 1 = 1
AND application_id = 200
AND NOT EXISTS (
SELECT 1
FROM xla_ae_headers xla_header
WHERE 1 = 1
AND xla_header.application_id = xla_tran_ent.application_id
AND xla_header.entity_id = xla_tran_ent.entity_id)
AND NOT EXISTS (
SELECT 1
FROM ap_invoices_all ap_inv
WHERE xla_tran_ent.source_id_int_1 = ap_inv.invoice_id
AND xla_tran_ent.entity_code = 'AP_INVOICES')
AND NOT EXISTS (
SELECT 1
FROM ap_checks_all ap_inv
WHERE xla_tran_ent.source_id_int_1 = ap_inv.check_id
AND xla_tran_ent.entity_code = 'AP_PAYMENTS')
