Example
In this example, we have a simple Income Statement module, with line items on rows, a time dimension on columns, and Organization and Versions as pages. The number-formatted Net Profit line item shows calculated net profit each month and is summed for quarters. We can use the PREVIOUS function in the number-formatted Month-on-Month Profit Change result line item against the Net Profit source to track profit changes for the actual version:
Month-on-Month Profit Change = Net Profit - PREVIOUS(Net Profit)
