Email function in 47 without commit work

I have a custom Function module which gets called through workflow on triggering an event, the custom function module uses SAP connect ('SO_OBJECT_SEND') to send an email. But in 47 these SAP Connect function modules will work only by giving explicit commit work which I cannot use in my custom function module because its getting called on commit through work flow. Plz advice me how to make the email functionality work in 47, which is working fine in my previous versions.
