Config for Requestable Entitlement in ARS based on selection in user form

[meghna_alias]

I have 3 dynamic attributes DA1 ,DA2 and DA3 where DA3 is child to DA2 which is indeed a child to DA1.

If DA1 alone is selected I want Config for Requestable Entitlement in ARS as
ev.customproperty13 = '${DA1}' and ev.customproperty11 = '${DA1}'

if DA1 and DA2  is selected
ev.customproperty13 = '${DA1}' and ev.customproperty11 = '${DA2}'

if DA1 ,DA2 and DA3 is selected 

ev.customproperty13 = '${DA1}' and ev.customproperty11 = '${DA3}'

Is there a way to achieve this condition? My customproperty11 value should be last selected dynamic attribute value.

ev.customproperty13 = '${DA1}' and ev.customproperty11 = case when '${DA2}' is null then '${DA1}' when when '${DA3}' is null then '${DA2}' else  '${DA3}' end

Hi RushiKesh,
Tried your solution but the system throws me below error:

[rushikeshvartak]

Your syntax is wrong please paste condition here 

[meghna_alias]

ev.customproperty11 = case
when '${dWell}' or '${dField}' is null then '${dOriginalOperator}'
when '${dWell_Wellbore}' is null then '${dWell}'
when '${dField_Well}' is null then '${dField}'
when '${dField_Wellbore}' is null then ${dField_Well}'
else '${dWell_Wellbore}' or '${dField_Wellbore}'
end
