Context Values for BEN_PEN_BNFT_AMT DBI

I am using BEN_PEN_BNFT_AMT to get the employee benefit amount for a given effective date. The routing information (SQL) obtained from below query shows 7 bind variables for the DBI.

select * 
from ff_routes_b 
where route_id =(select ROUTE_ID from 
                 ff_user_entities_b 
                 where user_entity_id =(
        select user_entity_id 
        from ff_database_items_b 
        where BASE_USER_NAME = 'BEN_PEN_BNFT_AMT'))

I am getting below error when I use GET_CONTEXT method -

AFDICT_APP_PREFIX-FF-1605057: Formula LL_BENI117_EOI_TO_VOYA_EE_CURRENT_AMOUNT_FF, line 27, database item or local variable PLAN_ID used as a context.
