Partial Payment of Invoice Through SDK

Hi all,

We'd like to support partial invoice payments on our website, as only full payments are allowed currently. If I try to process a partial payment however, I get the following message back from iMIS:

"Error: Order total exceeds payment amount".

I gather from this error that iMIS won't allow partial payments of invoices using the SDK, and that we must process these manually.

Does anyone have any suggestions to get this working?

Cheers,
Jordan.
