An XSL template is a customized template. If you need to repeatedly perform a set of functions, you can create an XSL template defining those functions, and then later call that XSL template whenever required. For example, if you need to perform addition of two numbers at regular intervals, you can define the addition function in an XSL template. You can then call this XSL template whenever required. 
The XSL Template option enables you to manage XSL templates. You can add, update or delete an XSL template using this option. Once you have added an XSL template, you can use it to map elements. You can also define the scope of an XSL template while creating and saving it. Scope of an XSL Template is the context within which it is defined. An XSL template can be defined in any of the following scope:

...

4. Select the scope of the XSl Template. The default scope of an XSl Template is Local.

   
   If you want to save the template as the Global Template, select the Global option. This will save the XSL template as Global XSL template and can be used in any mapping activity. In the Parameters panel, the XSL template will be displayed under the folder hierarchy Templates/Global.
