dimension lock issue

In AX 2009, when a sales order line is reserved against a purchase order or transfer order, and the dimensions are locked. When warehouse tries to receive the purchase order or transfer order line to another location, AX will not allow it. Depend on your customization that you may have a automated function to do the reservation based on the supply and demand. Behind the scene the unlock is pretty simple and straightforward.

On the inventTrans record, there is a field called InventDimFixed, if you find out each locking has its own defined number. In my example: 4 locked dimensions have value 263, 2 locked dimension has value 257. So you can just create a job or function to update the value accordingly. This will release the required dimension for receiving at the warehouse
