The data roots declared on the highest hierarchy level of an ST program are the root nodes of the tree structure of the data nodes of the main template. Addressing a data root during the execution of an ST program means referring to the bound ABAP data object.
As long as a data root is not shaded by the definition of a current node, you can access it directly using
“root“
where root is the symbolic name declared after tt:root.
At any position of the main template, you can access a data root root using
“.root“
where the period “.“ bypasses a possible shading by a current node.
In subtemplates, the rules for the root nodes of their tree structures apply.
