If a date shift changes the sequence of validity periods of a change object (for example, a characteristic), then you cannot perform a date shift. This rule does not apply to the object types BOMs and task lists. For these object types you would receive a warning message in the standard system.

A temporary log lists the change objects that prevent a date shift or cause a warning message. The log is created for each change object separately, for example:

• BOMs

• Task lists

• Classification system objects

These logs are only created temporarily. This means that when you finish editing and saving a change master record, the log entries are deleted.
