Using the date restrictions of the explosion profile, alternative dates are determined for each object, which encompass the validities or administrative data of the object. The following types of alternative dates exist:

• Created on
• Last changed on
• Valid from
• Valid to

For alternative dates of the types valid from and valid to, the relative position of the alternative date to the date limits in the explosion profile is determined. An alternative date can have values in interval, below, above, lower limit, or upper limit.
