Neither of the fields <ZK>Earliest start date </>(<ZK>from</> and <ZK>to
</>) are filled. (For Statutory Maternity Pay, these fields are named
<ZK>MPP start possible from</>).

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?

These two fields give the earliest and latest start dates of the
statutory absence. They are filled automatically by your SAP system,
derived from dates already entered in the system.
Ensure all other relevant dates have been entered into the relevant
infotype <ZK>SMP/SAP/SPP GB </>(0088) subtype screens.
For example, in the case of Statutory Paternity Pay (adoption), the
earliest possible start date of paternity leave is autromatically set
from the expected or actual date of birth entered manually into the
infotype screen.
