Payment periods for frequency &1 cannot be generated for &2 / &3

What causes this issue?

The period toolset is not able to generate payment periods for the given
selection range.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check to ensure that your date selection values and payment frequency
type are valid.

Procedure for System Administrators

For technical reasons, the date calculation routines of the Social
Services period toolset need to calculate some periods in advance. If
the end of year 9999 would be exceeded during the date calculation, the
calculation stops before that point to avoid system errors.
