Avoid Method Names That Overwrite Built-in Functions

WarningAnti-Patterns & Bad Practices#EC NO_OVERW_BUILTINRemote Enabled

Overview

Method name overwrites built-in SAP function.

ATC Finding Message: Method name overwrites built-in SAP function name

Rationale

Naming a method LINES, STRLEN, or XSDBOOL shadows a well-known built-in and makes the call site ambiguous. Readers cannot tell whether the built-in or the method is intended. Use a descriptive verb that does not collide with language functions.
