Foreign currency Revaluation (Remeasurement)

Summary

Foreign subsidiary with different ledger and functional currency

Content

From a Close and Consolidation reporting perspective, trial balance data from all the domestic and foreign subsidiaries are loaded to FCCS in its respective functional currencies.  All the data are then translated and consolidated in FCCS to the reporting currency for external reporting.

In the situation where the LEDGER currency of the foreign subsidiaries is different from its FUNCTIONAL currency, the data will need to be revaluated or remeasured to its functional currency prior to the consolidation process. 

Since currency revaluation or remeasurement should be done in the ledger, has anyone come across situations where the revaluation process cannot be completed in the ledger (e.g due to system constraints)?
