HASHED TABLE
Learn HASHED TABLE in ABAP with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
HASHED TABLE is an atomic ABAP topic inside Internal Tables. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what HASHED TABLE changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example
DATA hashed TYPE HASHED TABLE OF string WITH UNIQUE KEY table_line.
INSERT 'A' INTO TABLE hashed.
Check the input collection shape, whether the operation mutates or returns a new value, and what happens for an empty collection.
