Ranges tables
Learn Ranges tables in ABAP with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.
Ranges tables is an atomic ABAP topic inside Data Declarations. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what Ranges tables 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 ids TYPE RANGE OF i.
APPEND VALUE #( sign = 'I' option = 'BT' low = 10 high = 20 ) TO ids.
Check the input collection shape, whether the operation mutates or returns a new value, and what happens for an empty collection.
