This issue commonly occurs because every employee and applicant needs to be linked to an address template in order to be able to view them. These templates are linked to country codes.
If there is no country on the application, the system selects the country from the template that has the most recent date_effective.
There is a Portal parameter called cp_volc_default_country, this needs to be a valid country code.
To update the parameter, follow the below steps in Portal:
Go to the Administrator Dashboard.
Click Site Manager.
Click Admin Settings.
Search for cp_volc_default_country.
Click Edit.
Enter the Country Code.
Click Save.
Use the below if this does not work. It may be the case you need to add the country code to the address types.
To add country code to address types
Click CorePersonnel, Reference, Reference A-C
Select Address Type Codes
Click Add new Layout
Enter Effective Date - has to be later than current date effective
Select the Country
Ensure correct Address Type is assigned to Default Home Address
Add Country line as it is mandatory and necessary to make this work
