PutValueToExternalMap
Creates a variable that can be reused in a Job or Route.
When using a map in a Job, you can use the PutValueToExternalMap function to define a globalMap variable that you can then use in other components.
When using a map in a Route, you can use the PutValueToExternalMap
        function to save a value to an external map. You have to create and save the external map in
        the execution properties with the identifier
          org.talend.transform.externalmap.
    Information noteNote: By default the
          variable created is a String. To create a variable in another data type, it needs to be
          explicitly defined. For example, you can define a variable as a BigInteger using the XPath
          function xs:integer(%v).
