Transactions are dealt with based on the type of activity you intend to perform. You may or may not transact all the types of treasury activity a large enterprise engages in, but the functionality to perform these transactions is available:
Foreign exchange deals
Money market deals
Trade equities
Hedging deals
Bank balance management
Settlements
Foreign exchange transactions use spot and forward rates to transact (buy/sell) foreign currency amounts between the company (enterprise) and the counter party (bank).
Money market transactions include short term money loans that can be used by companies. These can be entered and managed with the treasury portfolio to ensure a single point of view for all your money transactions.
You can also transact in related negotiable instruments and derivatives within this functionality.
