To link one or more series to an aggregated series (1), you select the series to be connected in the table grid and then (2) select the aggregated series in the tree structure. Then click on (3) Connect or Connect with fractions to perform the linking connection.

Under Tree Controls are all the buttons described below.

Connect: Link a series to an aggregated series. Select the aggregated series in the tree and the series you want to link and then click on the button to perform the linking connection. Always aggregate 100%.

Connect with fractions: The same as Connect, except that you must use a proportion (fraction).

Edit fractions: Opens a new window to edit the fraction number for the selected series. Can also be changed so that the series is only to be aggregated, without fractions, and vice versa.

View Fraction date: Shows the tree symbols in the BuildTree window as the fractions for this specific date.

Remove: The link on the selected series in the tree is disabled.

Remove all below: Disables all links for the selected series. All items below it are unconnected.

Toggle between series tree and market tree: The market tree  toggle changes the Build tree window to view the connected series to different price areas
