There are two types of sub accounts in the system: expense and cost share. For cost share sub accounts, additional attributes are required that identify the source chart, account number, and sub account number that is to cover the costs incurred by the cost share sub account. Each time the accounting cycle runs expenses in a cost share sub account are automatically covered by a system generated transfer of funds. The transfer of funds moves money from the source accounting string to the cost share sub account for the amount of the expenses.
