some cases invoices received in foreign currency. but, GST amount should be posted and reported in SGD only. if customers or clients using SAP reporting currency (Local Currency: SGD) in this case there will not be any affect in GST amounts will be calculated correctly.

some customers using Local Currency other than SGD, in this case if tax invoice in foreign currency (other than SGD) but, fixed exchange rate for GST will be advised in Tax Invoice seperately.

Maintain GL Account for Exchange gain or loss posting relating to TAX

Posting entry using FB60
