Please correct the receivable account assignment

Hi!

I'm getting the error Please correct the receivable account assignment in autoinvoicing line.  By checking the note 1088218.1, I reviewed how the accoutning is for Receivables and it says Transaction types.  However we use the transaction type for loading some invoices by files, however we have another way to load invoice that use the autoinvoice so there must be another setup different than  transaction types. however we need to know how the receivables account qare taken from

The version is R12.2.4,

Any guide would be appreciated.

Thanks,

Claudia
