Use two columns in Case when - sql

Question

I am calculating five columns based on two columns using Case When. But it's not giving correct value. I have attached screenshot of correct result.
Results needs to be like:
Business Logic is - These five calculated fields has different definitions and dependent on predecessor filed. Definition of EER is, If an ID passes from a certain queues and also doesn't pass queue like FBR, CVL and CSP. EER field should have Yes in all rows of one ID. This goes on same way for rest four calculated fields as in case when statement. Once EER calculated, EES should be calculated for rest of IDs. So I used EER needs to be null for EES. An ID has Yes in one of five field it will be null in rest four field for same ID.
CREATE TABLE Table1
([ID] int, [QUEUE] varchar(7), [EER] varchar(4), [EES] varchar(4), [EEN] varchar(4), [EBNP] varchar(4), [NSB] varchar(4))
;
INSERT INTO Table1
([ID], [QUEUE], [EER], [EES], [EEN], [EBNP], [NSB])
VALUES

then 'Yes'else 'Null' end AS EER,
case when EER = 'Null' and X.Queue not in ('CSPWORK','CSPRACK','CSPEQUP') and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else 'Null' end AS EES,

Try this (updated query):
;with [data] as (
select [id], [queue] from [Table1] group by [id], [queue]

As mentioned by #HoneyBadger, you should do IS NULL check instead of equality operator. Note no two NULLs are equal, since NULL is just a mark to denote absence of value.
So the query should be.
Select Distinct X.ID,X.Queue,
case when X.Queue in ('IPTEST','IPPRV','IPPRECF','IPPMOM','IPCON','IPCFG','BDWXNG','LOCCLOS','BDWCNFG','BDWROUT')
and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%' and X.Queue not Like '%CSP%'
then 'Yes'else Null end AS EER,
case when EER is Null and X.Queue not in ('CSPWORK','CSPRACK','CSPEQUP') and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EES,
case when EER is Null and EES is Null and X.Queue Like '%CSP%' and X.Queue not Like '%FBR%' and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EEN,
case when EER is Null and EES is Null and EEN is Null and X.Queue not Like '%CVL%'
then 'Yes'else Null end AS EBNP,
case when EER is Null and EES is Null and EEN is Null and EBNP is Null and X.Queue Like '%CVL%'
then 'Yes'else Null end AS NSB
