If you change the option <ZK>Replicate NULL Values</>, then the
following considerations apply for the tables affected by the template:
The refresh behavior must be set to <ZK>Drop</>, and the relevant LTRS
settings must be updated.
If any field names contain an ABAP-reserved key word (you can find a
list of the ABAP-reserved key words in table TRESE), any field-related
settings for this field (for example performance options, mapping
values, or table structure deviations) need to be reset for this field.
If an event-based rule that uses an include program that refers to
nullable fields, then the include program needs to be updated.
If any field-based rules are assigned to nullable fields, they must be
removed.

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

Changing the value <ZK>Use Default </>to <ZK>Replicate NULL Values as
NULL</>

NULL Values as Initial</>
Changing the value <ZK>Replicate NULL Values as Initial </>to
