stock transfer from bin to bin

hi,

In stock transfer from bin to bin process i need solution for the below requirement...

a)The system must raise a warning when a material is transferred to another bin, which already contains the same material with a different batch number.

b)Transferring stock to a single batch location which already contains another material/batch is not allowed.

In bin to bin stock transfer process, it is possible by system to propose destination bin automatically ?

Thanks
