HR_PAYROLL: Payroll &1 cannot be executed for country grouping &2

What causes this issue?

The function module HR_PAYROLL is attempting to start payroll program
&V1&. However, this program does not exist or is not recognized as a
payroll program.

System Response

The application cannot perform the payroll run or payroll simulation.

How to fix this error?

Check your settings in the views T596F and V_T77CCE_PRG_PCE.
They must contain the entry 'CALCxx', where xx = the personnel country
grouping of your country. The name of the settlement program must be
assigned to this entry.
In your case, therefore, the entry 'CALC&V2& &V1&' must be defined if
the program &V1& exists and is specified correctly.
If the personnel country grouping '&V2&' is not known (that is, the
value = '??'), check whether the corresponding COUNTRY_GRP parameter is
transferred when the HR_PAYROLL or HR_PAYROLL_SIMULATION function module
is called. Correct this in your own code or create a customer message
for SAP Support.
