No source_id_int_1 was found in table xla_transaction_entities

Hi,

I encountered an issue which is really strange.

I checked some documents, basically we should use xla_transaction_entities.source_id_int_1=ap_invoices_all.invoice_id to connect ap and sla.

But now I can't find sla records using it. It seems there is no records about ap in table xla_transaction_entities.

How can ap transferred to gl if there is no record exist in sla?

And Is there any other way to connect ap and sla?

Please help~  Thanks!

Best Regards,

Ying
