Data not populating through Other Schema

Issue is :  the synonym of other schema unable to populate data from the schema owner.

Like the Schema owner is RMS14DEV and tha view table name is V_ITEM_MASTER. This table contains more than 100 data.

Now another schema is RMS_INTG.

I have created synonym as per below:

CREATE SYNONYM "V_ITEM_MASTER" FOR "RMS14DEV"."V_ITEM_MASTER";

then try to select data from RMS_INTG user and I do not get any data through the below query:

select * from V_ITEM_MASTER; [ Result : No rows selected ]

I have tried using public synonym also and got the same result.
