You can map source and target elements using certain buttons on the Tool Bar. These buttons are explicated as:

• • One To One Mapping ( Image Added )
  • Auto Mapper ( Image Added )
  • Remove All Mappings ( Image Added )

 One to One Mapping
If the number of leaf elements of the parent element in the source and target schema is same, then you can use the One to One mapping button to map all the source elements to the corresponding target elements. 

Steps to use One to One mapping 

1. Ensure that the source and target schemas are loaded and all their elements are listed under their respective nodes.
2. Click and drag the parent element of the source schema to the parent element of the target schema. This will apply template of the source parent element on the target parent element, and activate the One to One Mapping button.
3. Click One to One Mapping ( Image Added ) button. All the leaf elements of the parent element in the source schema will be mapped to their respective leaf elements of the parent element in the target schema.

 Auto Mapper
If the hierarchy and the names of the complex elements are similar, then you can use the Auto Mapper option to map the source elements to the corresponding target elements. In case of complex elements, the hierarchy and the name of all elements must be the same. 

Steps to use the Auto Mapper

1. Ensure that the source and target schemas are loaded and all their elements are listed under their respective nodes. Additionally, the hierarchy and name of the all elements is the same.

3. Select the mapping criteria from the Choose the Criteria dropdown list. Its options are listed as:
    
   • Ignore Case: The source and the target elements are mapped even if they are of different case. Their attributes are not mapped.
   • Case Sensitive: The source and target elements are mapped only if they are of the same case. Their attributes are not mapped.
   • Ignore Case and Include Attributes: The source and target elements and their attributes are mapped even if they are of different case.
   • Case Sensitive and Include Attributes: The source and target elements and their attributes are mapped, only if they are of the same case.
   • Consider Only Leaf Element Count: The source and target elements are mapped only if the number of leaf elements in the source schema and target schema are the same. It is not necessary that names of source and target elements are similar. Their attributes are not mapped.
   • Consider Only Leaf Element Count and Include Attributes: The source and target elements and their attributes are mapped only if the number of leaf elements in the source schema and target schema are the same. It is not necessary that names of source and target elements are similar.
4. Click OK button. All elements of the source and target schema will automatically be mapped based on the selected criteria.

 Remove All Mappings
You can use the Remove All Mappings option to remove all mappings from the Data Mapper.

Steps to remove all mappings between source and target elements 

1. Click Remove all Mapping ( Image Added ) button. The Remove Options screen is displayed. This screen displays a list of the properties, variables, custom methods, keys and templates associated with a mapped element, which can be removed with the mapping.

   You can remove mapping associated with each element individually. For details, refer to the section Remove Mapping of an Element.

Select the checkbox(s) of the options that you want to remove and click OK button. All the selected options and all mappings between source and target elements will be removed.

Custom Auto Map

The Auto Mapper feature can be used only when the elements of source and target schema are at the same hierarchy level and have the same names. However, if you want to automatically map the elements when the names of the elements of source and target schemas are different, you cannot use this feature. For example, if the source schema has elements, EmpFirstName and EmpLastName and the target schema has the elements, firstName and lastName then you cannot define mapping between these two schemas using the Auto Mapper feature. 

To define a mapping between the schemas when the elements of source and target schema are at the different hierarchy level (which may include elements at the different parent and child level) and have the different names, you can use the Custom Auto Map feature. This feature enables you to define the mapping between such schemas where elements to be mapped are stored in different parent and child level and in addition elements name are different. 

Scope of a Custom Auto Map

You can also select the scope of a Custom Auto Map at the time of defining and saving it. Scope of a Custom Auto Map is the context within which it is defined and is accessible within or across the user groups. A Custom Auto Map can be defined in any of the following scope:

...

In addition, you can also manage a Custom Auto Map from the Parameters Panel.

Defining a Custom Auto Map

You can define a Custom Auto Map by both manually providing the names of the source and target elements to be mapped in the Custom Auto Map Dialog screen or by defining the names of source and target elements to be mapped in a CSV file and then loading the CSV file in the Custom Auto Map Dialogscreen. Loading a CSV file is useful when you have a large set of source and target elements to be mapped.

Defining a Custom Auto Map Using a CSV File

Steps to Manually Define a Custom Auto Map

1. Ensure that the source and target schemas are loaded in the Data Mapper and all their elements are listed under their respective nodes.

3. Enter the name of Custom Auto Map in the Name textbox.

4. Select the scope of the Custom Auto Map. By default, the radio button Global is selected and a Custom Auto Map is saved in the Global scope.

    

   If you want to save the Custom Auto Map within the current user group, select the Group radio button. This will save the Custom Auto Map as the group Custom Auto Map and can be used in any mapping activity within the current user group. In the Parameters panel, the Custom Auto Map will be displayed under the folder hierarchy Custom Auto Map/Group.

5. Click the Add  button to add a new row for Source Element and Target Element columns. You can also add a row by pressing the Enter key. This will add the row immediately next to the row which is currently selected.
6. Enter the name of the source element for which you want to define Custom Auto Map in the Source Element column.

7. Enter the name of the target element to which you want to map the source element specified in previous step, in the Target Element column.

Defining a Custom Auto Map Using a CSV File

The Custom Auto Map feature also enables you to load a Comma Separated Values (CSV) file. You can use the set of values from the csv file which are separated by comma as a Map set for your process flow. For example, if you want to map the following source and target elements:

...

Similarly you can add more Custom Auto Maps.

Activating a Custom Auto Map

When you define a Custom Auto Map, by default it is in deactivated state. To use a Custom Auto Map, you need to first activate it. Once you have activated the Custom Auto Map, you can use it in your mapping. Note that only activated Custom Auto Maps can be used in a mapping. 
 

Steps to Activate a Custom Auto Map

...

You can now use this Custom Auto Map in your mapping. Similarly, right-click the Custom Auto Map and select the option Deactivate to deactivate a Custom Auto Map.

Using a Custom Auto Map

After activating a Custom Auto Map, you can use it in your mapping. Note that only one Custom Auto Map can be activated in the current mapping.

Managing a Custom Auto Map from Parameters Panel

You can also manage the Custom Auto Map from the Parameters Panel. When you right-click the Custom Auto Map in the Parameters Panel, you can perform the following operations on a Custom Auto Map:

...

Editing a Custom Auto Map
In edit mode, you can edit the name of the Custom Auto Map and the source and target elements to be mapped. Note that you cannot edit the scope of a Custom Auto Map in edit mode. The radio buttons to select the scope becomes non-editable once you save the Custom Auto Map. However, you cannot edit the Custom Auto Map when it has been already been used in the mapping and that mapping has been saved. 
 

Steps to Edit a Custom Auto Map

Moving a Custom Auto Map from Group to Global
You can also change the scope of a Custom Auto Map from the Parameters Panel by moving the Custom Auto Map from Group to Global. However, you cannot move a Custom Auto Map if it is in the activated state and has been used in mapping. In addition, you cannot move a Custom Auto Map from Global toGroup. 
 

Steps to Move a Custom Auto Map

...

This will change the scope of the selected Custom Auto Map and now the Custom Auto Map will be displayed under the Global folder.
