Clearing labels from all previous versions

Hi, I believe this is not possible because if you change a previous version you are actually creating a new version.
Because if it were possible to change a previous version, it would be losing history.

For the use case of "employees should only see the latest approved version in PDF" you could consider using the Version Control Lite add-on module: with this module you have a working copy that you edit (access restricted to the document authors) and a separate published version, usually as PDF, with wider access rights. The working copy can be edited without it affecting the published version until the new revision has been approved for publishing. I think this would help in your case without needing some tricks with the version labels.

If you are interested, I suggest talking to your M-Files representative and checking if your subscription already includes this add-on.

Hello Joonas, thank you, I have just checked, unfortunately this module is not included and I doubt that it is possible to get extra funding to upgrade it, but of course just in case I would ask for that from the manager. 

But in case it is not possible to get the add-on, do you have in mind the solution for my initial question? I want to believe that if there is a manual button to "clear this version label from the other versions of the object", in theory it can be activated automatically 

Unfortunately I don't think there's any automation like that built into M-Files. Perhaps possible as a custom extension but that requires some development effort and feasibility would need to be confirmed separately. That custom development requires funding also and I'd recommend to consider using the official add-on which handles the use case in a nice way.

Hello Marcio, label is kind of "spesific" property, you can manage the values through the value list, then go into document's history, choose the version you want and click "Add lable to this version", so this property will appear in metadata card of the particular version and you can address it through creating a view and setting the relevant filter. I used this trick to get initial versions of quality documents in our company, since for some reason first version sometimes started with "M", not "A".  

Okay, I see. Probably my development skills are not yet too high to perform this operation. 

Technically now the functionality I am talking about set in a way, that there is a view set to show approved revision (WF status in filter) and look in all versions. So it addresses the last approved PDF and if it is with a small blue icon, then it means document is being under different state currently. 

But as you can see there is one Obsolete, which should not be in this view, but as we have that filter set, M-Files refers to the previous approved revision and still shows this obsolete one
