Hi,
The easiest way to get the working capital calculated is creating a specific Management Reporter report. Simply list the accounts that are included in current assets and liabilities and calculate the difference.
If you want to break down the working capital by findim such as business unit or alike, you have to make sure that this findim is always posted when those balance sheet accounts are recorded. This can be achieved by making use of the balanced findim functionality that is available in the ledger form in GL.
Best regards,
Ludwig
