If for specific user report is not populating properly, for other users the same report is working fine.
Need to check the below table for that iview name and user name if some record is available then delete the same it will work.
delete from axcustomviews where name = ‘<iviewname>’ and username = '<username>'
eg: select * from axcustomviews where name = 'imachdtl' and username = 'ravi'
