Elements of Graphical Rule

The Mapping Expression area has a floating menu that contains two options for you to switch between the Graphical and Textual rule. You can drag this floating menu anywhere in the Mapping Expression area. 

Graphical elements are components which are used to represent any source, destination, mapping function, or parameter elements visually in Mapping Expression area. The following types of annotations described type, behavior, and functioning of the graphical interface and their elements. 

• Inputs
• Label
• Context Menus

Inputs: This shows the number of inputs a mapping function or a target element can have. Also, you can drag a line from input element to this section to use that as input in this mapping function/target element.

Context Menus:  Context menus are used to perform below actions:

• • Start connecting lines to map an element to another element(s).
  • Remove an element/box from the graphical mapping workspace.
  • More Menu will have below options
    • Information about mapping element
    • Remove incoming mappings from the elements
    • Add selected graphical mapping element's syntax/expression as a local variable.
    
    
    
    
    

Applying mapping functions using Graphical Rule

You can use the option, "Graphical Rule", available under the Mapping Expression tab in the web mapper. 

1. Ensure that the source and destination layouts are loaded and all their elements are listed under their respective nodes.Click Mapping Expression tab from Mapping Functional Panel.

2. Select a destination element which you want to map. 

   Tip
   Unless you select a destination element first, the Mapping Expression tab will be grayed out.

   
   

3. Click Mapping Expression tab at the left bottom of the screen.

4. Click the desired mapping expression. This displays a list of sub-functions associated with the selected mapping expression.
5. Select the

   Note
   Mapping Expression tab gives you two interfaces, Textual and Graphical to perform the mapping. By default, the Graphical Rule is active. To perform mapping in Textual Rule interface, refer to this document.

   The destination element that you have selected will be visible in the mapping expression area.

6. Double-click a source element that you want to map with the destination element. 

7. Click a mapping function that you want to use and select the desired sub-function and use it to map the source and destination elements. For example, using Concat sub-function.

   Note
   You can also add a parameters in the mapping expression area by double-clicking the parameter's name in the Parameters panel.

   
   

8. Click String mapping function and select Concat sub-function.

   The syntax for the Concat sub-function is displayed

    
   Once you have all the corresponding graphical elements (source elements, destination element, and mapping sub function) available in the mapping expression area, do the following:

   Tip
   You can drag and reposition the graphical mapping elements anywhere in the Mapping Expression

   Area.

9. This syntax has two parameters. Double-click a source element that you want to set as the first parameter. This displays the selected source element in the syntax.

Similarly, double-click another source element as the second parameter. This is displayed in the syntax.

You can indent the textual rule content as per your requirement.
10. This maps elements using the concat sub-function. A line is displayed between the source and target panels showing the mapping of the source element to the target element.
11. Once you have performed the mapping activity, click Save button to save the mapping.

For details on using these mapping functions, refer to the section Using Mapping Functions. 
While mapping elements, certain suffixes are displayed next to source and destination elements in the Source and destination Panels.

1. area.

   1. Click each of the source elements and select the  icon from the Context Menu to connect the source with the respective Inputs of Concat sub-function. 

   2. Click the Concat sub-function and select the  icon from the Context Menu to connect with the destination element. 
      The source elements are now mapped with the destination element using Concat sub-function and the mapping is visible in the mapping panel.

   Tip
   You can reposition the entire mapping within the Mapping Expression area by clicking anywhere and moving the cursor.

   
   

Color coding of connecting lines

There will 3 color codes for the lines.

• Green     : Lines connecting two elements within Graphical Mapping workspace will be green in color if the both elements are visible in current size of graphical mapping workspace. 
• Grey       : Lines connecting two elements within Graphical Mapping workspace will be grey in color if any of the two element is not visible in current size of graphical mapping workspace. 
• Orange  : Lines connecting two elements within Graphical Mapping workspace will be orange in color if that element is selected. 
• he graphical mapping workspace will be scroll-able to view elements which are not adjusted in current visible size.
