Reversal of TU with status "Active"

Hi all

My TU status is "Active"

Door activity is completed. And the loading task is cancled.

In this situation i want to change the TU status from "Active" to "Planned".

Please let me know this is allowed or not?

To complete the goods issue, i can other options like process the goods issue manually on the delivery or can un-assign the delivery like other ways i can follow. But i want to know the TU status can be changed from "Active" to "Planned" or not.

Please give some views on this.

Thanks

Aras
