Get restrictions on Assign / Update Item

[GabrieleZelasco]

Good morning everyone,
in our solution (c#, Vault2023) I need to intercept the assign/update article call made by Vault 2023 starting from a cad file (by api of course).

In the event where I intercept the call, I should check the Part Number property if it meets certain requirements before the item is created and associated with the file.

If it does not meet these requirements, I would like to block the creation of the item adding restriction.
I have tried ItemService.PromoteItemEvents.GetRestrictions but it crashes the Vault, I assume because it works when updating an item and not a file.

Can anyone tell me which event or workaround I can use to achieve this ?

Thank you very much

Hi all. I was wrong about the ExtensionRestriction constructor:
public ExtensionRestriction(System.string objectName,System.string message)

If objectName is null then Vault crashes.

ItemService.PromoteItemEvents.GetRestrictions is what I needed.

It works starting from File and Item both.

I apologize. Thanks to all
