Document &1 could not be checked for changes

What causes this issue?

To enable the document to be checked, the "Check" column must be
selected for the relevant shift report type prior to execution of the
IMG activity "Define Shift Report Types".
The check as to whether the document in question was changed subsequent
to its creation could not be carried out in this case because at the
time of creation and saving of the document the relevant Customizing
setting had not been made. Later activation of the check has no effect
on already created documents.
