what's the workaround?
The workaround I've looked into is a pain, and we should really make this easier - so I've added
DEV-8116 to do this.
In the case of the Creditor Purchases form in Jiwa, the journal emitted when activating for a foreign currency creditor is simply a credit to the creditor control account, and a debit to the offset account (the column on the creditor purchases form is captioned "Ledger Number"). Both journal transactions have the BAS Code "No Code".
What you want is the transactions to have the code "Purchases G11", and amount to the offset account to be the transaction amount minus the value of GST, and then another additional transaction for the GST amount, to the GST Acquisitions account and also with BAS Code "Purchases G11".
This is the journal you get:

- Journal_Emitted.png (10.83 KiB) Viewed 11202 times
This is what you want:

- Journal_Wanted.png (14.73 KiB) Viewed 11202 times
So a manual journal entry can be made to do exactly that - but it requires a little effort to work out the GST amount manually and then do the adjustment journal.
I'm not an accountant, so you might want to check with our support department if this is right.
