Map Execution Properties
You can specify properties (named values) when you execute a map using any of the mechanisms to invoke a map. These properties can be read during map execution using the GetMapProperty function.
If you are using an ESB to execute a map, the properties of the message triggering the map execution are automatically included as map execution properties.
