Regular expressions

Learn Regular expressions in ABAP with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

Regular expressions is an atomic ABAP topic inside Expressions & Strings. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Regular expressions 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

FIND REGEX '^[A-Z]{2}-[0-9]{3}$' IN 'AB-123' MATCH COUNT DATA(matches).
Edge case / engineering note

Change the key input in this ABAP example and predict the result first; the named construct should be the reason the behavior changes.
