''lock'' document in sharepoint

[gjeh]

Hello everyone.

I've created a PowerApp to enable users to browse through a sharepoint library (displayed in a Gallery) and have them manage the metadata fields of pdf documents in the library. There is a PDF Viewer element on the page which displays the selected pdf document.

However my PowerApp is (hopefully) going to be used my several users at the same time, and I don't want to have users 'managing' the same document at the same time. Preferably I'd make it as when a user selects a document that within a reasonable amount of time the document is checked-out/locked/etc. so other users won't be able to select it in the gallery or maybe not even apear in the gallery anymore.

I'm wondering what methods I could approach to achieve my goal, if any methods are available.

Hoping to hear your thoughts.

Hi @gjeh ,

I will try to give you a concept here.

You could have a field in the library metadata "locked" with the user's name and time/date text or similar and Patch to this to the list when the document is opened. You could reset it when the document is closed or even activate a timer of the user's computer and reset it after a selected time. If another user tries to open a "locked" document, you would give them a message "Locked by xxxx on xxxx". You might also consider some override options
