I want to drag a process Segment B, which is a container, in the process Segment A.
The logic would be, that A is now a children of B.

Hi,

You should define a container drop tool https://www.eclipse.org/sirius/doc/specifier/diagrams/Diagrams.html#container_tools.
Then in the operation make B a child of A. See https://www.eclipse.org/sirius/doc/specifier/general/Model_Operations.html to understand how it works.
Use a change context with

var:newSemanticContainer

that will be A.
Then a Set operation to make B a child of A with something like

aql:newSemanticContainer .children->insertAt(0,element)

as value expression and children as feature.
