Update Customers header level and limit by the same ledger responsibility or the same user

I want to update customers on header level.

It can update when the same ledger responsibility or the same ledger user.

 

But I don't know how do this setup or custom.

Have any idea about this case?

Oracle ERP EBS 12.1.2

we have a lot of ledger, and each has a different key user.

So I hope that achieve access control.

My responsibility have set by ledger or operating unit.

And when I update customer/supplier, I hope others user can not update customer/supplier created by me.

Thanks.
