Prevent the same change request approver from approving twice . . .

[Igor Tsalyuk]

During the change approval process for a normal change, approvers are groups and they are based on the CI and Business Service. There is a scenario when the user could be a member of multiple groups, so the same approver could show up as the approver more than once. We are trying to prevent the same approver from being able to approve twice. What would be a good way to do it. I was thinking of using a Business Rule, but I am having trouble getting it to work. I am new to ServiceNow, so I am open to any suggestions.

We use the Business rule mentioned here in the ‘Duplicate Approval Requests Not Required’ Business Rule https://www.servicenowguru.com/scripting/business-rules-scripting/prevent-redundant-approval-request...

Hi Michael, thank you for your reply. Your solution works well. It's not the way I wanted to do this, but it does the job. I was going to set to not_required at the time when the first approval occurred, For example. The approver is a business approver and he approves the change, at the time when approval changes the state to approved, the Business Rule would check if this approver shows up more then once and set the state for another approval(not the current one) to not_required. Do you think it's even possible to do using Business Rule?

Thanks.

Igor
