As of Release 3.0: Table T134H is maintained incorrectly.

Solution
Please maintain table T134G (or T134H) - via the corresponding Customizing transaction. The business area you have to enter in this table for plant (or valuation area) and division of the material is transferred by the system into inventory posting. (transaction/event key BSX).
The same applies especially to stock transfers and transfer postings, regardless of whether they are executed with or without stock transport order. The business area for the isssuing material-plant (or valuation area) is set in inventory posting for the issuing stock and in inventory posting for the receiving stock, the business area of the receiving material-plant (or valuation area) is set.
