3409712 - Project Task Cannot be Deleted from Sales Order After Assignment

You have assigned an incorrect Project Task to a Sales Order and saved the document. You now wonder if the incorrectly assigned Project Task can be deleted.

SAP Business ByDesign 

1. Go to the Sales Orders work center. 
2. Open the Sales Orders view.
3. Find Sales Order ABC (Where ABC represents the ID of the Sales Order which has an incorrectly assigned Project Task).
4. Open the document and click on View All .
5. Navigate to the Items tab.
6. Highlight a line item and scroll down to the Cost and Revenue Assignment section.

In the item that had a Project Task assigned, you notice that the value of the field cannot be deleted.

Once a Project Task has been assigned to a line item in a Sales Order, the field becomes mandatory and does not allow the deletion of the Project Task assigned.

This is the expected system behaviour.
