Assigning a Function Without a Source Node Link

About this task

To define a mapping rule in which the input for the destination node is provided by the return value of a function and not from a source node:

Procedure

  1. Select the Functions tab. In the Functions tab, the list of available functions is displayed.  

  2. In the Functions tab, expand folder that contains the function to assign to the destination node. This function must have no input parameters. For example, the Get Current® Date and Time function has no parameters and returns the current date and time.
  3. Select the function icon and drag it into the Mapping Editors middle pane, near the destination node you want to map.
  4. In the Mapping Editor, drag from the function icon to the destination node. A link from the function to the destination node is displayed.
  5. Optional: Test if the mapping rule is valid by right-clicking on the function in the mapping rule and selecting Apply Function Graph. If the mapping rule is valid, the square function icon in the graphical representation of the mapping link is not displayed and a function icon is shown to the left of the destination node icon, as shown in Figure 1.
