Not able to view employee type supplier from supplier form

A few setup steps required:

1) Get the  menu attached to the problematic responsibility
    > System Administrator > Security >  Responsibility > Define

2) Navigate to System Administrator > Application > Menu
Query the menu attached to the responsibility

3) Include the function:
Create/Update Employee Supplier Details (POS_HT_SP_EMP_SUPPLIER) with the grant flag checked in the menu of the responsibility for full access to employee suppliers.
OR
View Employee Supplier Details (POS_HT_SP_RO_EMP_SUPPLIER) with the grant flag checked in the menu of the responsibility for read only/inquiry access to employee suppliers.

Alternatively check the grant flag for the function POS_HT_SP_EMP_SUPPLIER in the menu POS_HT_SP_FULL_ACCESS_MENU.
> However then all users that can create standard supplier will also be able to create employee supplier.

4) Bounce the Apache server OR 'Clear All Cache' from Functional Administrator responsibility, so that the Function Security related caches will be cleared and the above changes can take effect.
