Setting Page Items from SQL Query

Question

Hi, </br></br>
I am using "SQL Query (PL/SQL function body returning SQL query)" for a report. In the body of the sql query, after calling a function, I have the following statement: </br></br>
APEX_UTIL.SET_SESSION_STATE( p_name => 'P13_MESSAGE', p_value => 'Contact Tech Support' ); </br></br>
and I find that I cannot save the query. I get an error message: </br></br>
<b>Unexpected error, unable to find item name at application or page level.
ERR-1002 Unable to find item ID for item "P13_MESSAGE" in application "4000". </b>
</br></br>
I do have the field 'P13_MESSAGE' on my page. </br></br>
Can't this API call be used within such a query type? Is there an alternative to this? </br></br>
Thanks in advance </br></br>

Scott,</br></br>
I have given the source of the region, below. Its type is 'SQL Query (PL/SQL Function body Returning SQL Query'). </br></br>
"Get_State_Hit" is a procedure in a package. I have not shown the name of the package here.</br></br>
Please give me your suggestion. </br></br> Thanks </br></br> Vasan </br></br>

DECLARE </br>
l_sql varchar2(100); </br>
BEGIN <br>  
IF(:P13_MATCH_TYPE = 'ALL') THEN</br>
    Get_State_Hit ( one set of values from user-interface );</br>
    apex_util.set_session_state( p_name => 'P13_MESSAGE', p_value => ' MsgString 1' );</br>
ELSE</br>
    Get_State_Hit ( another set of values from user-interface );</br>
    apex_util.set_session_state( p_name => 'P13_MESSAGE', p_value => ' MsgString 2' );</br>
END IF; </br>
l_sql := 'Select Col 1, Col 2, ..., Col 9 from ABC_Vw'; </br>
RETURN l_sql;</br>
EXCEPTION</br>
WHEN OTHERS THEN</br>
l_sql := 'Select * from Default_Vw' ;</br>
apex_util.set_session_state(p_name => 'P13_MESSAGE', p_value => 'Contact Tech Support');</br>
RETURN l_sql; </br>
END;</br></br>
