How do I populate Customer Since in the Advanced Collection Collections Screen? Below is the note provided in the Implementation doc

The Year Established Field has been populated on the customer record. Now I am expecting to see this value in the Customer Since screen in Advanced Collections. See screen shot. Please advise.

Note: This field displays the date of the customer's first purchase stored in the Year Established field on the Oracle Receivables Customer page. The Receivables user must enable this field by adding the field through page personalization and then populate it in order for Advanced Collections to show a date.
