The call hierarchy displays the chronological flow of your transaction, program, or function module. To display the list, choose  Goto Call hierarchy Standard from the overview screen of the runtime analysis transaction.

The number in the Levels (Le) column shows the depth of each call. If you double-click a call in the hierarchy, the system displays the corresponding subhierarchy. To display the call hierarchy of all include programs, choose  Goto Call Hierarchy Include Display .

The memory requirements in the last column are only displayed if the measurement restrictions (Aggregation) do not specify aggregation, and the Memory usage field is selected. The value 0 is output in this column in all other cases.
