Concat(DISTINCT{<YEAR={2018}>*<logistics={'OV'}>*<HYBRID_L={0}>*<PRIORITY={"$(=FirstSortedValue(PRIORITY,aggr(min(PRIORITY),CUSTOMER,PRIORITY)))"}>}QUALITY_ON_TEN)

@pradosh_thakur ..

@anushree1  , @Anil_Babu_Samineni 

Sir you all gave me solution for one previous doubt . hence adding you 

[anushree1]

Hi Please find the attached , output on qv matches your desired output except for Customer 3 I am unsure if its typo error on customer 3 or the logic different, please check and let me know

[prahlad_infy]

Thank You Anushree1 for the reply .

Actually for customer 3 for 2017 the lowest priority is 1 , but its logistics field is NULL , though CLASS is A ...
Hence , it should have Null result 
while for 2018 the lowest priority is - 3 hence it should display 8 as result 

our search cond should like be 

1) first find the lowest priority 
2) check if corresponding Logistics is OV , if yes then 

3) Check class if its A , if yes then populate corresponding QUALITY_ON_TEN 

else populating Null 

Hope i am explaining myself clear .

I made little change in data and your expression in not giving expected result ;

Final:
Load *,
if(len(trim(HYBRID))=0,1,0) as Null_Flag;

Temp:
LOAD * INLINE [

CUSTOMER, YEAR, PRIORITY, logistics, HYBRID, CLASS, QUALITY_ON_TEN
CUSTOMER 1, 2018, 6, , , , 9
CUSTOMER 1, 2017, 3, , HY, A, 1
CUSTOMER 1, 2018, 4, NU, LY, , 5
CUSTOMER 1, 2017, 4, NU, LY, A, 2
CUSTOMER 1, 2017, 2, OV, , , 7
CUSTOMER 1, 2017, 8, OV, , A, 8
CUSTOMER 1, 2017, 1, OV, , A, 10
CUSTOMER 1, 2018, 7, OV, , A, 5
CUSTOMER 1, 2018, 1, OV, , A, 9
CUSTOMER 1, 2018, 3, OV, HY, A, 7

CUSTOMER 2, 2018, 1, OV, , A, 3
CUSTOMER 2, 2018, 3, OV, HY, , 6

CUSTOMER 3, 2018, -3, OV, , A, 8

CUSTOMER 3, 2018, 6, OV, , A, 0
CUSTOMER 3, 2017, 1, , , A, 8
];

10 should be the result for 2017 , 9 for 2018 .
