Mapping helps in passing data from preceding nodes to the succeeding nodes.

The output variable of each node is available to be mapped as input in all the subsequent nodes.

Edit Mapping Data Window

Click the link between two nodes. Edit Mapping Data window opens. 
You can select the node from where you want to map the elements in the dropdown on the top of the left panel in the mapping screen. All the preceding nodes get listed here.
All the output variables of the selected node get listed on the left-hand panel of mapping screen.
You can select the value and pass them to current node.

There are two types of mapping windows based on the nodes.

  • Map output variables from preceding nodes as input variables to the current node using ADD option, for example, Excel node, Web UI node.
  • Map output variables from preceding node to selected parameter of the current node using ELEMENT/EASY MAP option, for example, Email node.

You can map elements in any order and need not match with the order in the tree structure.

Use ADD Option

  1. Expand the tree structure of the attribute you wish to map on the left-hand panel.
  2. Select the output variable to be mapped.
  3. Click the ADD button.
    The variables are added in Where to put? field and path of the variable are added in What to get field.
  4. Rename the variables as required to make them intuitive for further use in the current node.

Element Map

You can select the parameter to be mapped from right-hand panel and pass value to it from the preceding nodes using ELEMENT MAP option.

  2. Select the parameter to be mapped from both the panels.
