+Secondary KPIs
+~~~~~~~~~~~~~~~~~~~~
+
+Secondary KPIs helps user to aggregate and visualize additional or alternate KPI values in the node widget. 
+Specifically, in a model with two data series, these are the set of secondary metrics captured under the primary value of the node

+
+As a default, there are three secondary values displayed for a dual series data in the following order
+i. Full Period Variance between baseline and comparison metric (in % and absolute values)
+ii.	Baseline metric value for the first period in the series 
+iii. Variance for the first period between baseline and comparison metric (in % and absolute values)

+Secondary KPI option lets users to customize these secondary values or metric according to their preference 
+
+Users can achieve this using:
+I.	Secondary KPI option based on Formulas
+II.	Secondary KPI option based on Template
+
+I.	Secondary KPI option based on Formulas

+In the below model screenshot, the user can display the data value from Operating Profit %’ and ‘Operating Expense Ratio’ as Secondary KPI values to the TOP node ‘Operating profit’.

+
+Under the 'Operating Profit' node setting's 'Secondary KPI' ribbon, user needs to select the 'Formula' button and fill-in the label name and the custom formula for his additional Secondary KPIs

+
+II.	Secondary KPI option based on Template
+
+In the model, user can display ‘Contribution’ of each of the child nodes Water, Beverages, and Others to their parent node Gross Profit. 
+User should define ‘Contribution’ as a Formula in one of the nodes and call them out for ‘Contribution’ calculation using the Template option at the other nodes.

+
+In this example, user can define the formula in 'Water' node under the node setting's Secondary KPI by selecting 'Formula' button and defining the 'Custom Formula'
+Upon completion, 'Contribution %' is displayed as a Secondary value of the node widget.

+
+To borrow this formula on other nodes, user can fo into the Secondary KPI setting of the 'Beverages' node, select the 'Template' button, and choose to display the same formula as the 'Water' node.
+User can instantly see the corresponding 'Contribution %' at the 'Beverage' node.

+Similarly, following the same steps for the 'Other' node helps the user to instantly visualize ‘Contribution %’ for the all the child nodes to Gross Profit
