How to update Named Value Manager config?

If you mean the standalone "Named Value Manager" application; I would personally say that this isn't something you should use these days.  You can configure Named Value Storage using the Advanced Vault Settings from M-Files Admin.

That said: the answer would be the same for both...

Setting the value in Named Value Storage simply changes the stored value.  It does not force whatever application is using that value to refresh its configuration.  It really depends what value it is you're changing, but often the practical way to force the application to see the new configuration is to restart the vault (or application, possibly).

Thanks for your reply Craig and yes despite restarting the vault it didn't update the config for the application.  I have reached out to Support in the meantime and also investigation if there is a better way to achieve this requirement.  I was a bespoke application created for us some years ago

Thanks again

I would reach out to the developers of the application.  I assume that this information is configuration data for the application.  For newer vault applications that can be exposed nicely within M-Files Admin without you having to edit JSON configuration manually yourselves; it'll also even automatically apply when the changes are saved.
