| The effect of exchange rate changes on cash and cash equivalents held or due in a foreign currency. [Refer: Cash and cash equivalents] | en | http://www.xbrl.org/2003/role/documentation | http://www.xbrl.org/2003/role/link |
| Report the value, for the reporting period, of effect of exchange rate changes on cash and cash equivalents. Unrealised gains and losses arising from changes in foreign currency exchange rates are not cash flows. However, the effect of exchange rate changes on cash and cash equivalents held or due in a foreign currency is reported in the statement of cash flows in order to reconcile cash and cash equivalents at the beginning and the end of the period. This amount is presented separately from cash flows from operating, investing and financing activities and includes the differences, if any, had those cash flows been reported at end of period exchange rates. | 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 |
