Error Code 33 when finalising supplier invoice in Supplier Orders

If you elect to process a supplier invoice through the Supplier/Purchase screen you will need to click the "deliver" button prior to finalising the invoice.

If you try to finalise the order straight to invoice you will receive an error code 33 - record not available error.

Reason - selecting "deliver" allocates the stock to file and creates a record that is used during finalisation. Don't use deliver, the record is not created and the record not available message results.
