Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

If you want to use task lists without package assignments, you need to
modify the message type for this message in Customizing. You can modify
the message type in the Customizing activity Message Control under

have items without package assignments. You can include items without
package assignments in a task list that already has at least one item
with a package assignment. Otherwise, message IP364 is issued, just as
