How to update Inactive collector and credit analyst in existing customers

Hello,

We are on PeopleSoft 9.2 Image 33. We are upgrading to Image 46. Bills are generated from prepaid lines in Contracts via contract billing interface process. While trying to create bills from contracts, BIIVC000 is going to warning status with invoice error as -" Missing Active Collector". This is because customer bill to options contain inactive collector. Is there a way to update existing customers with Active collectors & credit analyst via online pages without SQL updates?

Values in the below setups contain Active users but existing customers setup in the past don't contain active values-

1. Set Up Financials/Supply Chain > Product Related > Billing > Setup > Assign Collector for Billing.
