My purchase requisition ticked in ME51n Document overview

Hi Gurus,

I have one issue where "My purcahse requisition" option is ticked for one user because of which system is taking more time to open tcode ME51n as first it checks for the PRs for that users in the background.

I have not found any simple tick to remove this for particular user setting.

Need your expertise on this as we want to remove that tick for this user.

Thanks in advance.
