Custom code for LOV generation in Custom.pll

Question

Hi All,
I am using the custom in my custom application, I am using the following procedure in Custom.pll for LOV generation. When I use the same procedure standalone then it's working fine, But when I use it in Custom.pll then it's giving me the Error "No-Data-Found", please let me know what to do. I am assuming that it can't find the appropriate backend table, I am logging in through sysadmin/sysadmin, Also I have fully followed the procedure for Table registration and Synoym creation and assiging it to apps but even then it's giving me the above mentioned error.
procedure event(event_name varchar2) is
rg_id RECORDGROUP;
query_string VARCHAR2(2000);
crnt_item VARCHAR2(60) := name_in('SYSTEM.CURSOR_ITEM');
crnt_type VARCHAR2(30) := GET_ITEM_PROPERTY(crnt_item, DATATYPE);
-- Omit crnt_hint if not context sensitizing the LOVs.
crnt_hint VARCHAR2(30) := SUBSTR(GET_ITEM_PROPERTY(crnt_item,
HINT_TEXT),
INSTR(GET_ITEM_PROPERTY(crnt_item,
HINT_TEXT), ':') + 2);
begin
IF event_name = 'WHEN-NEW-BLOCK-INSTANCE' THEN
IF (form_name = 'FRM_EXPATIENTMASTER' and block_name = 'REG_EXPATIENTMASTER' and item_name = 'DEFENCECODEFK')
then
crnt_item := SUBSTR(crnt_item, (INSTR(crnt_item, '.') + 1));
query_string := 'SELECT DISTINCT reg_defencecategory.defencecodepk'
|| ' AS holder_value '
|| ' FROM hms.reg_defencecategory'
|| ' ORDER BY 1';
IF NOT ID_NULL(FIND_GROUP('generic_lov_rg')) THEN
DELETE_GROUP('generic_lov_rg');
END IF;
rg_id := CREATE_GROUP_FROM_QUERY('generic_lov_rg', query_string);
SET_LOV_PROPERTY('generic_' || crnt_type || '_lov',
GROUP_NAME, rg_id);
IF FORM_SUCCESS THEN -- >From "IF" to "END IF" may be omitted
-- if not context sensitizing the LOVs.
SET_LOV_PROPERTY('generic_' || crnt_type || '_lov',
TITLE, 'Available ' || crnt_hint || ' values');
SET_LOV_COLUMN_PROPERTY('generic_' || crnt_type || '_lov',
1, TITLE, crnt_item);
END IF;
LIST_VALUES;
/* IF name_in('control.holder') IS NOT NULL THEN -- Holder is set to null in Lov_Btn WBP trigger
COPY(name_in('control.holder'), crnt_item); -- Depends upon implicit conversions for non character
-- datatype values (in this example, NUMBER and DATE). Create a 'holder' for/of each datatype
-- required to avoid implicit conversions.
END IF;*/
end if;
end if;
exception
when no_data_found then
message('No Data Found, try Again');
null;
end event;
