different output of same report for 2 different user
I have a column "Parent material" in a report. When this report is run by user X it populate only one parent material value say 1111. But, when same report is run by user Y with same selection criteria, it populates the different set of parent material value say 1111,2222,3333,4444,5555.
Can anyone please tell me why output of same report is different for two users.
Thanks in advance.
Please ask user to delete any persinalization of variables done by him/her.
