Hello,

For 'Add non worker' new UI ,We have a list of value of non worker types.
This list includes values that Electra Israel doesnt  use.
I saw its a lookup type code: PER_NON_WORKER_TYPE  , AND lookup of LEVEL 'Extensible'.
How can we remove the values? edit ? for this lov.
and if its not possible , how can we still have a list like this with the values we would like ? (not DFF ).

see screens below.

Thansk a lot,
Revital.
