Avoid Complex Expressions in Call Arguments

Overview

Avoid complex expressions in call arguments.

ATC Finding Message: Avoid complex expressions in call arguments; extract into a variable

Rationale

Method call arguments should be simple variables, literals, or single method calls. Nesting deep method chains or complex expressions like COND #( ... ) inside arguments reduces readability and makes debugging difficult. Extract complex expressions into local variables before the call.

Non-Compliant

lo_service->process( iv_param = lo_factory->get_builder( )->build( ) ).

Compliant

DATA(lo_item) = lo_factory->get_builder( )->build( ).
lo_service->process( iv_param = lo_item ).
