On the fly creation of BP

Hi,

When I am doing the stock transfer from one BP to another,the system is creating on the fly "TO" BP's inspite of not having any relationship with the TO BP in Item Branch Records.Is there any way we can avoid that in Latest E1 release?This is creating a huge problem because users are transferring the Items from Correct BP to Incorrect BP's.Below I got some information from White paper but it is not helping.

Thanks
