I apologize, but as stated in my previous response, the net changes in working capital cannot be calculated with the information provided. To do so, I would need the opening and closing balances of current assets (excluding cash and cash equivalents) and current liabilities. This data is not present in the extract you sent. Do you have the Statement of Financial Position (Balance Sheet) for the relevant periods? If so, please send it over, and I can help you calculate the net changes in working capital.
