Employee number getting blanked out in the buyer form

Hello,

We use shared Oracle HR with oracle purchasing and financials.

One of our employees surname changed as she got married. Hence going by the naming convention, we changed her Oracle user name and assigned to the new employee record.

We added her in the buyer form too.

However we are getting below error when she tries to open the purchase order form.

You are not setup as a buyer. To access this form you need to be a buyer.

We noticed the employee number in her buyer record is blanked out.

we updated it with the correct employee number and saved.
