Navigate to the 'Transactions' tab

Click the transaction you wish to allocate for accounting.

You can quickly find transactions that need to be mapped by clicking GL pending on the left side. 

GL Mapping can be done in this side view

 Location can be changed and a single GL and/or department can be mapped (splits are done in expanded view)

Remember Allocation - mapping will be remembered and applied to the next transaction from the same merchant

Click this button to open the expanded view

You can even split the amount into different GL Accounts by selecting Add Split.
