POST MAPPING TO ACCESS RUN TIME REPO

Question

Hi all,
In my mapping , I have a post mapping process wherein, I want to identify the execution status of the mapping wherein the mapping name is passed as a parameter to the following query
SELECT
C.RTA_STATUS,     C.RTA_SELECT
FROM ALL_RT_AUDIT_MAP_RUNS A ,WB_RT_AUDIT C
WHERE A.MAP_NAME=v_mapping_name
AND A.MAP_RUN_ID = (SELECT MAX (B.MAP_RUN_ID) FROM ALL_RT_AUDIT_MAP_RUNS B WHERE B.MAP_NAME=v_mapping_name) and A.EXECUTION_AUDIT_ID = C.RTE_ID
But I am not able to get the result in to my variables..This is very urgent can anybody please help me..
Thanks in Advance.
Thanks & Regards

Sumana, the post-map process will run no matter what, so you can just test the current status to determine what to do.
For example, I have a standard post-mapping procedure that logs execution details to an audit schema that centralizes collection of execution stats for all processes run in our warehouse. It goes something like this:
procedure finalize (p_process_id in number,
p_process_name in varchar2)
is
l_status varchar2(20);
l_numread number := 0;
l_numInserted number := 0;
l_numUpdated number := 0;
l_numMerged number := 0;
l_owb_audit_id number := 0;
l_owb_status number := 0;
sqlStmt varchar2(2000) :=
'begin '||
' :1 := '||p_process_name||'.get_selected; '||
' :2 := '||p_process_name||'.get_inserted; '||
' :3 := '||p_process_name||'.get_updated; '||
' :4 := '||p_process_name||'.get_merged; '||
' :5 := '||p_process_name||'.get_runtime_audit_id; '||
' :6 := '||p_process_name||'.get_status; '||
' end;';
begin
-- we use dynamic SQL to return required audit field values.
-- This allows us to alter which values we need at a later date
-- without impacting the deployed mappings.
-- M.B.
execute immediate sqlStmt
using out l_numread, out l_numInserted, out l_numUpdated,
out l_numMerged, out l_owb_audit_id, out l_owb_status;
-- map OWB status values to our internal codes.
if l_owb_status = 2 then
l_status := 'ERROR';
elsif l_owb_status = 1 then
l_status := 'WARNING';
else
l_status := 'SUCCESS';
end if;
-- and end the process in the audit tables
erscntl_audit_log_pkg.process_end(p_process_id,
1,
l_status,
null,
l_numRead,
null,
l_numInserted,
l_numUpdated,
l_numMerged,
null,
null,
null,
null,
null,
null,
null,
l_owb_audit_id);
end;
You can see where I am translating the status for my purposes, but you could use this to test the status instead.
the process_name input variable is established by a standard constant in our mappings which is set with a value of get_model_name so that a change to a mapping name is automatically updated internally in the call to the pre- and post-mapping procedures;
Cheers,
