Insufficient priviege issues while creation of refresh FAST on commit MV alone.

Hello Team,

I been created materialized view log on base table then when I issue on demand as follows can able to execute and create MV successfully.

create materialized view 

MV_PCX_ANH 

BUILD IMMEDIATE 

REFRESH FAST ON DEMAND WITH PRIMARY KEY

as 

select id,INSUREDGROUPOTHERDESC,OPERATIVETIMEDESCRIPTION 

from pc2user.PCX_ANHINSUREDGROUP_AVI@IGW11R where INSUREDGROUPOTHERDESC is not null or OPERATIVETIMEDESCRIPTION is not null;

But we want to refresh automatically once commit issued in the base table hence if use FAST ON COMMIT as follows

create materialized view 

MV_PCX_ANH 

BUILD IMMEDIATE 

REFRESH FAST ON COMMIT WITH PRIMARY KEY
