| Other comprehensive income, before tax, gains (losses) on revaluation | en | http://www.xbrl.org/2003/role/label | http://www.xbrl.org/2003/role/link |
| The amount of other comprehensive income, before tax, related to gains (losses) in relation to changes in the revaluation surplus. [Refer: Other comprehensive income, before tax; Revaluation surplus] | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
| Report the value, for the reporting period, of gains or losses on revaluation, before tax. If an asset’s carrying amount is increased as a result of a revaluation, the increase shall be recognized in other comprehensive income and accumulated in equity under the heading of revaluation surplus. However, the increase shall be recognized in profit or loss to the extent that it reverses a revaluation decrease of the same asset previously recognized in profit or loss. If an asset’s carrying amount is decreased as a result of a revaluation, the decrease shall be recognized in profit or loss. However, the decrease shall be recognized in other comprehensive income to the extent of any credit balance existing in the revaluation surplus in respect of that asset. The decrease recognized in other comprehensive income reduces the amount accumulated in equity under the heading of revaluation surplus. | 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 |
