An item line from a sales order with a connected wave needs to be deleted by the user. Even if the Wave is finished and the Pick Task for the impacted item is marked as Done or deleted, this cannot be done. By doing this, a system error is generated.
Solution:
Users can make the item line close in the sales order itself.
- Open the sales order
- Click Edit
- edit the line level and check the Closed column.
- Save the Sales order:
By closing the item line user may not be able to fulfill the same item and will get an error.
