External Payment Parameters - Identifiers don't exist

Hello @Link 

It is due to function in Ext_Pay_Param_Id_Msg_Code_API

Your transaction type is Supplier Payment and function returns FALSE for this transaction type. That is why you dont have  identifier per message code.

Originally, MT940 is set to Direct Cash Trans for message code 105

FUNCTION Is_Valid_Ident_Trans_Type(
   statement_trans_type_ IN VARCHAR2,
   identifier_type_      IN VARCHAR2 ) RETURN VARCHAR2
IS

   FUNCTION Core(
      statement_trans_type_ IN VARCHAR2,
      identifier_type_      IN VARCHAR2 ) RETURN VARCHAR2
   IS
   BEGIN
      IF (statement_trans_type_ IS NULL) THEN
         RETURN 'TRUE';
      ELSIF (statement_trans_type_ = 'CUSTOMERPAYMENT') THEN
         IF (identifier_type_ IN ('1', '2', '3', '4', '5', '6', '7', '8')) THEN
            RETURN 'TRUE';
         END IF;
      ELSIF (statement_trans_type_ = 'DIRECTDEBITING') THEN
         IF (identifier_type_ IN ('1', '2', '3', '4', '5', '6', '7', '8')) THEN
            RETURN 'TRUE';
         END IF;
      ELSIF (statement_trans_type_ = 'DIRECTCASHTRANS') THEN
         IF (identifier_type_ IN ('1', '2', '3', '4', '5', '6', '7', '8')) THEN
            RETURN 'TRUE';
         END IF;
      ELSIF (statement_trans_type_ = 'CASHISSUEDCHECK') THEN
         IF (identifier_type_ IN ('1', '2', '3', '4', '5', '6', '7', '8')) THEN
            RETURN 'TRUE';
         END IF;
      END IF;
      RETURN 'FALSE';
   END Core;

Hope this helps
