E9.2 Changing Job Code on WO


We are in need of giving our users the ability to update the Job Code on a Work Order. To do this I added JBCD to the grid on P3112 WO Routing using a Form Extension. We are able to update the JBCD field on F3112, but this does not update the Machine Run Hours and Labor Run Hours fields. Is there a UBE or some process we need to run after updating the job code in this example?
