What are the Steps To Record Foreign Currency Exchange In Multinational Companies Which Use ( SAR & EUR & USD & QAR & SW USD )?

On daily basis all the accounts are reported in its respective local and foreign currencies. These foreign currencies accounts get revalued once every month (end of the month) for regulatory and Group reporting with spot exchange rate. The system generates the Exchange profit / loss amount on revaluation of Assets and liabilities at the end of the month and reverse P&L on the next day. 

I want to add to mohammed answer

 1_ First we need to define the reported currency for example SAR 

2_ translate all income statement elements to reported currency and gain or loss will be reported as other comprehensive income or loss 

I appreciate all add value to this subject as special challenge
