Added the condition : (DOMAIN_NAME = SYS_CONTEXT('gl_user_ctx','domain_name')) OR <above query> for the Read/Write predicate and the issue is resolved. This this, I am able to insert new Order Base.

But now facing another issue: Inserting new Order Base manually works fine. But create new Order base by copy from another order base, get the error:
{? = call vpd.is_domain_writeable(?,?)=null}; inParams=[OB_ORDER_BASE, FWD]; outParamType=class java.lang.String
Checked function vpd.is_domain_writeable and determined that the issue is in select statement: v_select_stm. Dynamically generated v_select_stm is:

select 1 from domain where domain_name = 'FWD'
and (DOMAIN_NAME = SYS_CONTEXT('gl_user_ctx','domain_name')) OR EXISTS (SELECT 1 FROM ob_line obl, LOCATION_CORPORATION lcr WHERE lcr.LOCATION_GID = obl.SOURCE_LOCATION_GID AND obl.order_base_gid = OB_ORDER_BASE.order_base_gid AND lcr.CORPORATION_GID = SYS_CONTEXT('gl_user_ctx','CORPORATION_GID'))
and EXISTS ( SELECT 1 FROM domain_write_grants_made_v WHERE grantee_domain LIKE SYS_CONTEXT('gl_user_ctx','vpd_domain_name') AND domain_name LIKE grantor_domain AND table_name = 'OB_ORDER_BASE')

The above query will obviously fail. But not sure on how to modify the predicate such that query will work fine in Copy Order Base also. Help appreciated.
