Click the object symbol for Subprocess in der Symbols bar.
BPMN contains a multitude of symbols. Therefore, only the basic symbols are displayed in the modeling toolbar. During modeling, only the symbols that are allowed are displayed in a logical order.
Click the position in the modeling area where you want to place the object. Lines indicate the alignment of the moving object to the placed objects and arrows indicate the distances.
Click the relevant symbol. The symbol currently selected is highlighted.
If multiple symbols are allowed, they are offered for selection. If only one symbol is allowed, it is placed. If no symbol is allowed, an error message is displayed when placing the symbol.
Enter the relevant name.
Place the objects that should be part of the subprocess onto the subprocess and enter their names. If necessary, enlarge the subprocess symbol.
