PL/SQL :: How To Pass Object Type As Input For Search Criteria

I have search function that takes the input parameters and returns all the matching rows. this is straight forward only. My problem is having multiple types as a input parameter. that is the reason i am not able to pass the input value for these types.

My Input Type table looks like this.

CREATE OR REPLACE TYPE T_T_PARTY_REQUEST_CRITERIA
AS TABLE OF T_O_PARTY_REQUEST_CRITERIA;
/
CREATE OR REPLACE TYPE T_O_PARTY_REQUEST_CRITERIA
AS OBJECT
(
SYSTEM_IDENTIFER VARCHAR2(50),
PROCESS_TYPE VARCHAR2(50),
[code]........

Last two inputs are type again.my question here is how to pass the values for these two T_T_PARTY_KEY_IDENTIFIER and T_T_ADDTN_IDENTIFIER_INFO. I have defined the the last two types following.

CREATE OR REPLACE TYPE T_T_PARTY_KEY_IDENTIFIER
AS TABLE OF T_O_PARTY_KEY_IDENTIFIER;
/
CREATE OR REPLACE TYPE T_T_ADDTN_IDENTIFIER_INFO
AS TABLE OF T_O_ADDTN_IDENTIFIER_INFO;
/
[code].......

I have pasted the query here from my function. when i pass the null as part of input for these 2 types my query is working. otherwise it is saying invalid Identifier.First I tried with first Type.

I am passing the value as

(PRKYTP.PRTY_KEY_TYP_NM = ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM OR ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM = 'ALL' OR ITTPRC.PARTY_KEY_IDENTIFIER.PARTY_KEY_TYP_NM IS NULL);

Error is Error(34,147): PL/SQL: ORA-00904: "ITTPRC"."PARTY_KEY_IDENTIFIER"."PARTY_KEY_TYP_NM": invalid identifier

SELECT DISTINCT T_O_PARTY_REQUEST_IDENTIFIER(PR.PRTY_RQST_ID) BULK COLLECT INTO T_T_P_R_CRITERIA
FROM TABLE(CAST(I_T_T_PARTY_REQUEST_CRITERIA AS T_T_PARTY_REQUEST_CRITERIA)) ITTPRC,
PRTY_RQST PR
JOIN BUSN_APPLC BIAP ON BIAP.BUSN_APPLC_ID = PR.BUSN_APPLC_ID
