An explanation of the most common terms that are used in this scenario.
For example, a For statement in a message map that produces one output for each input is converted to a ForEach transform in a graphical data map. It is flagged for review and is explained in more detail on the Documentation tab of the Properties view.
When a converted message map includes calls to predefined ESQL map (esql:) functions, each of these calls is converted to an XPath or Custom XPath transform. If there is no XPath equivalent of an ESQL map function, it is replaced with a Task transform in your graphical data map. You must replace each of these Task transforms with a Custom XPath, Custom Java, or Custom ESQL transform that re-creates the required behavior.
If the map is complex, you can use the Task transform like code comments to indicate what further work needs to be done.
