Delivery already contained in shipment, deletion of the outbound delivery impossible

Dear all,

The process is following:

First we delete the freight order: FO 6100022255 duly canceled.

After that we tin spot successful our papers travel of the outbound transportation that the freight bid disappears:

But if we present privation delete the transportation an mistake connection is visible:

Delivery already contained successful a shipment

Cancelling is impossible

After redeeming the transportation = automatic instauration of a caller Freight bid = 6100022305

How is it imaginable to lick this problem? We privation delete the delivery. But if we delete the freight bid and afterwards we prevention the outbound delivery, abruptly a caller freight is created.

Very champion regards
