FREE - no_id
ABAP Syntax(Obsolete) FREE MEMORY.
What does it do? If the addition ID is not specified in the
statement FREE MEMORY , then all data
clusters are deleted from the ABAP memory.
Latest notes: This short form is extremely error-prone and forbidden in
classes, since a FREE statement without ID affects all data
clusters.
