PXSelector is not showing BAccountID values on Service Order screen after selecting CustomerID value.

Hi Everyone.

Hope you are doing great!

I have created a grid on the Service Order screen (GraphExt) with 2 field like the below

Problem 1: The EmployeeID field what is selector one is not showing the EmployeeID values after selecting the CustomerID field on the Service Order screen.

Note: For new record without selecting the CustomerID value then selector is working fine.

Problem 2: I’m trying to defaulting the Service Role and EmployeeID values from another screen.

Here the problem is, values are defaulting but the instead of showing the AcctCD values it is showing the bAccountID values.

FYI

Problem3: Selector heading is also showing wrong one.

DAC fields:

                        serviceRoles.Role = branchRole.Role;
                        serviceRoles.EmployeeID = branchRole.EmployeeID;
                        RolesGridView.Cache.Update(serviceRoles);
                    }
                }
            }
        }

Could you please assist me to resolve this issue.
