AP_CHECKS_ALL.PAYMENT_METHOD_LOOKUP_CODE and AP_CHECKS_ALL.PAYMENT_METHOD_CODE in Oracle APPS

Below is from Oracle Metalink ID 1919051.1

PAYMENT_METHOD_LOOKUP_CODE is obsolete in R12 hence it should not be referred in R12. If you want to refer payment method code from Invoice header then PAYMENT_METHOD_CODE should be used. During upgrade to R12 we populate PAYMENT_METNHOD_CODE with PAYMENT_METHOD_LOOKUP_CODE for migrated invoices.

SELECT payment_method_code, payment_method_name, description

  FROM iby_payment_methods_tl

 WHERE payment_method_code IN

          (SELECT DISTINCT PAYMENT_METHOD_CODE

              FROM AP_CHECKS_ALL

              )
