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 need 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).
