FPO1P - Display of doubtful entries

Dear all,

I am testing transaction FPO1P for a client requirement.

I sometimes have the tick box "Display of doubtful entries" that is appearing on the tab Output Control.

However, the tick box is not always visible in this transaction (on the same environnement, same test).

For example: Here it is not visible

Here, the box is visible:

Is there any reason?

Thanks for your help,

Regards,
