Supplier Name Not Syncronised with Employee Name

 Hi,

The Employee name Stands Like this

Last name: Sudhir Sharma

First name: KP-090890

So the Employee name is : Sudhir Sharma KP-090890 (Last Name First Name)

but in supplier name it displays as

KP-090890 Sudhir Sharma (First Name Last Name)

I want to syncronised employee & Supplier name so the supplier name should be same as employee name.

Supplier Name should display exactly as employee name.

I have tried running 'employee update program' but no result. we are using R12.1.1

How can i achive this?
