I just found this blog:
Differences between ccBPM(Integration Process) and NW BPM
I found that "NW BPM does not support message attachments" whereas ccBPM does at the bottom of the comparison list. In other words, we were able to use ccBPM to pass an attachment from asynch file to SOAP response, however, now in NW BPM we are not able pass an attachment? That doesn't make sense ... I thought NW BPM works with web services using SOAP envelopes which can support attachment
Is it true that NW BPM does not support message attachments?
