Can I register an event on a table from another scope?

Hello Everyone,

I have a table #a in scope A.

Scope B is an application that is dependent on scope A.

In scope B runs a business rule on table #a.

In this business rule I would like to call an event.

If I try to register this event in scope B, but than I can not select the table #a because the event is in scope B and table in scope A.

This latter is also described on the wiki:

Event Registry - ServiceNow Wiki

What is the best workaround / Solution for this?

These are the workarounds I can think of:

  • I can register the event in scope A, but this also requires me to create the business-rule in scope A, because I cannot call an event from another scope.
    • I call the event like this while in scope B: gs.eventQueue('scope_a_name.event_name');
    • However I get the following message: Security restricted: Access to event 'scope_a_name.event_name' from scope 'scope_b_name' has been refused. The event defined in sysevent_register is in scope B.
  • I can thus better register both business rule and event in scope A and this is the workaround I currently use.

I would like to hear any opinions, best practices

Thanks and Kind regards,

Tom

It looks like you are correct on the approach. The caller (business rule) must be in either global or the same scope as the event registration. However, I did notice that the event listener (email notification or script action) can listen from a different event.



For example:


BR in scope A (or global) can fire Event in scope A, to trigger an email notification or script action in scope B.
