Dear Laslaris Laskaris,
Currently, in 1C:Drive, to change the status or another attribute of a document (like a Purchase Order) or a catalog item, you can use the Batch attributes editing functionality (Settings > Application settings > Administrator tools > Data adjustment > Batch attributes editing).
It is available for users with Administrator's rights in the system.
Also, we plan to implement the way that would enable a user having no Administrator's rights to change the status of several selected POs or other documents directly from the list of these documents - in a couple of clicks.
Thank you for the hint!
