Fetches the value of a variable defined in a Job or Route.
When using a map in a Job, you can use the GetValueFromExternalMap function to retrieve the value of a globalMap variable.
When using a map in a Route, you can use the GetValueFromExternalMap
function to retrieve a value saved in an external map. You have to create and save the
external map in the execution properties with the identifier
org.talend.transform.externalmap
.
To use the Test Run feature with this function, you need create a CSV file in the Sample Data folder of the Hierarchical Mapper that contains sample key-value pairs. By default the name of the file should be org_talend_transform_externalmap_properties.csv. It can be modified in .
