This indicator determines the type of message you see if you carry out a date shift that changes the sequence of effectivity periods for BOMs and task lists.
It is possible to carry out a date shift that changes the sequence of effectivity periods for BOMs and task lists.
Usually, you see a warning message in this situation.
However, if you do not want to date shifts to be allowed in this situation (as is the case for all other change object types), set this indicator. All the messages that you normally see as warning messages are converted to error messages. This prevents you from carrying out a date shift if this situation applies to BOMs and task lists, too.
