Hi
One of the way would be to use the Liquidity flow in Cash Management, which would give you the indirect method of cash flow. You can use the Planning Group/Level to define the nature of transactions and create the flow.
Alternatively, use FSI1-6 to create a cash flow report by creating various nodes and grouping your GL Accordingly. If some of your GL Accounts are used for multiple purposes, you may need to break them into more than one GL depending on your requirements.
