When cancelling a goods receipt material document, the resulting transfer order proposes a source bin different than the bin the material was initially placed in with the original transfer order. The bin proposed can be changed, but would like for it to default to the original bin.
As I understand you are processing a TO from a TR that was created when you cancelled the GR (I mean no autom TO is in use in this case). So we can speak about resulting TR since you cannot change source bin in 'resulting TO'.
In SAP you cannot cancel a TO except TO for delivery (please check SAP help). So, I think your TR that was created as a consequence of GR-cancellation offers the source bin based on your master data / customizing settings (search strategy) and there's no link between the 'original' and the new TO.
So, you cannot expect SAP to offer the same bin as source bin unless your settings would make it possible.
When you cancel the material document (in MBST or in MIGO) it doesn't cancel the 'belonging' TO.
