I am having the problem described in this support article.
support.microsoft.com/.../974134
I am trying to import a general journal, which is both intercompany and multicurrency.
I need to import different exchange rates on different lines of the journal.
The support article suggests that this can't be done saying
'When you expand the line for the distribution, the Exchange Rate field is also not available to select and change.', but this is not true, the transaction can be entered manually, so should be able to be done through integration manager.
