| Treasury shares [member] | en | http://www.xbrl.org/2003/role/label | http://www.xbrl.org/2003/role/link |
| This member stands for the entity’s own equity instruments, held by the entity or other members of the consolidated group. | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
| This member stands for a component of equity representing equity instruments of the reporting entity that have been issued and subsequently reacquired by the entity. If an entity reacquires its own equity instruments, those instruments (‘treasury shares’) shall be deducted from equity. No gain or loss shall be recognised in profit or loss on the purchase, sale, issue or cancellation of an entity’s own equity instruments. Such treasury shares may be acquired and held by the entity or by other members of the consolidated group. Consideration paid or received shall be recognised directly in equity. | en | http://xbrl.ssm.com.my/role/ssm/fs/mfrs/lab_rol_ssmt-fs-mfrs_2017-12-31/ReportingDocumentation | http://www.xbrl.org/2003/role/link |
