To Integrate materialized view Refresh in DAC Execution Plan

Question

We have couple of materialized views which we want to get refreshed in DAC execution plan.
We have referred Technote "BI_Apps796_Perf_Tech_Note_V8" which detailed how materialized view can be refreshed in DAC Execution Plan.
We have followed below steps but our materized view is not getting refreshed.
1. Create new Task Actions in DAC using "Tools -> Seed Data -> Actions -> Task Actions"
with SQL Statement link
BEGIN
DBMS_MVIEW.REFRESH('getTableName()', 'C');
DBMS_STATS.GATHER_TABLE_STATS(ownname => 'getTableOwner()', tabname=> 'getTableName()', cascade => TRUE, estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FOR ALL COLUMNS SIZE AUTO', degree => DBMS_STATS.DEFAULT_DEGREE);
END;
2. Defined custom MV as a table in DAC
3. Added custom MV as the related table to the original Fact.
4. Reassembled corresponding Subject Areas and rebuilt Execution plan
But the MV is not getting refershed. Neither could locate any task in Ordered Task which will refresh this MV.
Have we missed any step? Any pointers in this direction would be appericiated?
Do we have to specify action .. to task "Load Fact table tas" and specify Success action as Refresh MV?
How can we trace task in All tasks/Ordered tasks in DAC EP to locate task corresponding to MV refresh?

Answer 1

Thanks Veeravalli for Suggesion!
Tried adding Task action Refresh MV as action type "Success Action" for Fact task .. It did add a step of Refresh MV for load Fact Task in EP
But it is passing the Orgininal Factable name as to be refreshed as MV which is giving DB error.
"Refresh MV" for WC_B_TEST_F failed on "DataWarehouse"
sql: BEGIN
DBMS_MVIEW.REFRESH('WC_B_TEST_F', 'C');
DBMS_STATS.GATHER_TABLE_STATS(ownname => 'olap', tabname=> 'WC_B_TEST_F',cascade => FALSE, estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE, method_opt => 'FORALL COLUMNS SIZE AUTO', degree => DBMS_STATS.DEFAULT_DEGREE);
END;
Error: MESSAGE:::ORA-23401: materialized view "OLAP"."WC_B_TEST_F" does not exist
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2563
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2776
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 2745
ORA-06512: at line 2
instead of WC_B_TEST_F, we wanted "OLAP"."WC_B_TEST_MV" to be refreshed
Do we need to create another task for MV refresh rather than task action? and add Refresh MV as task action there?
Thanks,
