Cannot cancel picking

We are still having issues with orders not allowing us to cancel picking. It still shows the unhelpful error message as well. Order:SO016750 Sku:DL20005 You can attempt to cancel this pick for testing purposes.

To cancel picking there are 2 methods.

1. Cancel Picking by details – this will cancel the picked and system will try to move the stock back to the original location. But if the original location is already max, then you will hit into message to inform as below as explained in the ticket: [RAP] INCIDENT REPORT 6– 89330348

1. User Anti Picking – to cancel picking and system will put the system qty in the location RESERVEPICK_500. Then you can trigger a move from there to the location which is available.
