You can only enable Breakback for line items that are number formatted and do not contain formulas.
To enable Breakback for specific line items:
- Open the module in Blueprint mode.
- Scroll across the columns and select Breakback for each line item.
You can enable breakback for every new line item that is added to a module either from the Modules screen, or by opening the module in Blueprint mode. At the top of the Breakback column, select New Line Items: On.
Total cells that have beakback enabled have a blue triangle in the top-left corner. Hover over the breakback marker to see how many cells are impacted by breakback. You can hide the breakback markers in the Help menu. Select Hide breakback markers.
