Quality Notification Number skip

Hi

When I am creating a quality notification of type V3. The new notifications are getting created with notification numbers are sporadically being assigned and in 80% of the cases they are not increasing by one.

In our quality system (QA), the number assignment is working correctly but not in production. The configuration in QA is identical to that in Production.

What is causing this issue?

Sincerely,

Nicky
