I am currently using odoo 10.0 CE and I am having troubles with conversions in journal entries. My company currency is IDR and here is how are setup currencies:

However when I check the journal entries the conversion is not done properly, here is an extract of the report for buying goods in Singapore and so in SGD:

720 289 905,56 / 3 740,68 = 19255,58 which is not the exchange rate.

Some help on that matter would be much appreciated.

Best regards,
