List item - Population - Based on Data setup

Question

Dear All,
I need to populate the list item based on data defined at the database level.
Tables Used:
Table 1 : JBCAI_JOB_COM_ADD_INFO
Column Name     Pk     Null?     Data Type     Default     
JBEDC_UID          1     N     NUMBER (22)          
JBCAI_ADD_INFO_CODE     2     N     VARCHAR2 (2 Char)          
JBCAI_INFO_CODE_SEQUENCE      3     N     NUMBER (3,1)     1     
JBCAI_ADD_INFO_TEXT     Y     VARCHAR2 (35 Char)          
SHIPCOMP_CODE     N     VARCHAR2 (4 Char)     
Table 2 :CODES
CODE_TYPE CODE_VALUE DESCRIPTION NEXT_VALUE CODE_FLAG
MCAR 01 Customs References 01 NULL N
MCAR 02 Customs References 02 NULL N
MCAR 03 Value of Commodities NULL N
MCAR 04 Currency of commodities NULL N
MCAR 05 Purchase Order Number NULL N
MCAR 06 Other NULL N
MCAR 07 Consignee Name NULL N
MCAR 08 VIN NULL N
FORMS Section
=========
JBCAI_ADD_INFO_CODE are the list items which needs to be populated; JBCAI_ADD_INFO_TEXT(free text) which user can enter any descriptions.
References - Label of the Block
JBCAI_ADD_INFO_CODE JBCAI_ADD_INFO_TEXT
Customs References 01 - Free Text()
Customs References 02 - Free Text()
Value of Commodities - Free Text()
Currency of commodities - Free Text()
Purchase Order Number - Free Text()
Other - Free Text()
Consignee Name - Free Text()
VIN - Free Text()
VIN - Free Text()
Business Rules:
If JBCAI_ADD_INFO_CODE has the flag as 'N' in CODES table then user can select only one time from the list item.
If JBCAI_ADD_INFO_CODE has the flag as 'Y' in CODES table then user can do multi-selection from the list item e.g; VIN
How the records are fetched:
Value for the list item are been populated from CODES table ; which am doing through the below query.
In WHEN-NEW-FORM-INSTANCE am using the below code:
PROCEDURE p_fetch_code_value
IS
          l_query VARCHAR2(200) ;
          l_rg_name VARCHAR2(40) := 'CODES';
          l_errcode NUMBER;
          l_rg RECORDGROUP;
     BEGIN
          l_query := 'SELECT adcod.description description,adcod.code_flag code_flag FROM codes adcod WHERE adcod.code_type = ''MCAR''                    AND adcod.code_value IN (''01''''02'',''03'',''04'',''05'',''06'',''07'',''08'') ORDER BY code_value';
          l_rg := FIND_GROUP( l_rg_name );
          IF ID_NULL(l_rg) THEN
          l_rg := CREATE_GROUP_FROM_QUERY(l_rg_name, l_query);
          END IF;
          l_errcode := POPULATE_GROUP( l_rg );
          POPULATE_LIST('BLK_CONTROL.JBCAI_ADD_INFO_CODE',l_rg);
EXCEPTION
Handled WHEN OTHERS exception
END p_fetch_code_value;
Saving of Record:
List value selection are saved to JBCAI_JOB_COM_ADD_INFO.JBCAI_ADD_INFO_CODE column.
Free Text is saved to JBCAI_JOB_COM_ADD_INFO.JBCAI_ADD_INFO_TEXT column.
Doubt:
When i select the first list item value i.e Customs References 01 and then enter some description i.e free text and moved to the next list item; the value Custom reference 01 should not be visible wheras the other values should have to be visible e.g; Customs Reference 02,Value of Commodities.....
Please help and let me know how can i acccomplish this task?
Thanks....

Hi Sarah,
Thanks for your reply.
There is no issue in the population of the list item; it is working fine with the query which i have pasted.
My doubt is:
There are few places where i have set the code_flag as 'Y' / 'N'.
For the first time when user selects the list item; all the values should be shown.....
If user has selected the first list item i.e Customs Reference 01 for which the code_flag is 'N' from a multi-record block; then when he moves to the further lines the previous selection for which the flag is set as 'N' should not be shown(if user has already selected once) e.g; 'Customs Reference 01' should not be shown again if user has made the selection before.
Plz revert incase more explanations required.
Thanks...
Regards,
Sunil.G
