Transfer Fixed Asset between two Entities

You would first dispose the fixed asset in entity which it resides.  This can be done by going to GL, Fixed Assets, View all. Find the fixed asset and click on Dispose. The system will ask you for the selling price and the Cash account to deposit the proceeds. After posting, the system will write off the asset and book revenue or loss from the sale of the asset based on current value.
 
In the other entity you need to move it to, you will create the fixed asset, GL menu, new asset, The asset account, contra-asset account and expense accounts are required. You can keep the balancing account blank and the purchase cost 0 and Accumulated Depreciation 0. Create the fixed asset.  

Then go create a bill to purchase the fixed asset. If you have the setting at setup, feature settings, bills , show linked to fixed asset activated, you can enter a new bill item and choose the fixed asset created, you will be asked to enter an amount for the purchase, a GL account which you can choose any account as it will not be used when the bill is posted and a description. Post the bill and the system will post the value on the bill as the beginning asset value of the fixed asset.
