Resetting the date can cause inconsistency

What causes this issue?

This financial document has already been assigned to SD documents. In
this assignment, the system checks whether the date is consistent with
the dates in the SD document. If the date has been reset to the past,
it cannot be guaranteed that the SD dates still lie in the respective
periods.

How to fix this error?

Choose Environment -> List -> List of assigned SD documents and check
the consistency for the assigned documents.
