You can use /INT4/IFTT_DEL report to delete old Test Cases or to schedule the job that will delete Test Cases on regular basis.
On the selection screen you need to specify Scenario ID. With below checkbox you can include subfolders of the selected scenarios to be included in the processing.
You need to provide number of days which after which you would like to delete Test Cases.
It is strongly recommended to run report first in Test Run to check what Test Cases will be deleted. If run without Test Run checkbox, Test Cases will be removed without further checks or popups.
You can provide additional parameters to specify your selection.
