Asset transfer within co code

Dear Friends,

We have 5 plants and have configured segment reporting.

Plant A is transfering their car to plant B.

I am using t-code ABUMN to transfer asset from old asset to new asset. there is error : Posting with trans.type 300 not possible , how can i amend it?

my second question is:

Since we have segment reporting: we also want that sale and purchase entry figures in books for both plant A and B. not just at co-code level the assets get transfered. We would like to see dep being posted in Plant A books for used period of asset and same for plant B from purchase date.

Thank you for your expert guidance.

Sanjay
