Infotype not found in feature SSPLP; no check for change of per.calendar

What causes this issue?

When infotype Absences (2001) is updated, the employee#s personal
calendar is also amended accordingly. The feature <ZK>SSP/SMP Infotype
- PIW Linking Decision </>(SSPLP) checks whether any such changes to
the personal calendar are relevant to linked Periods of Incapacity for
Work (PIWs) for calculation of Statutory Sick Pay (SSP).
Feature SSPLP is currently missing an entry for the relevant infotype
and consequently, no check can be made to determine whether changes to
the employee#s personal calendar involve linked PIWs.

How to fix this error?

personal calendar. This can be performed using transaction PE03 in the
