LET expression

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

12 min read • Advanced

LET expression is an atomic ABAP topic inside Modern ABAP. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what LET expression 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

abap-08-05-let-expression.abap
abap Try It Live 
DATA(total) = COND i( LET a = 3 b = 4 IN WHEN a < b THEN a + b ELSE 0 ).
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.
