@YoussefKacem1 try below. Idea is you first need to find the stores which are audited then on next load you can use not exist using that ID
Data:
LOAD ID,
AuditType ,
Date ,
if(AuditType='Audit1',Store.Code) as Store.Code.Audit,
Store.Code ,
Score
from Source.QVD ;
Left Join(Data)
LOAD distinct Store.Code,
1 as Flag
Resident Data
where not Exists(Store.Code.Audit,Store.Code);
drop field Store.Code.Audit;
