Hello. I'm not sure I understand. Are the SFA and the platform case you're trying to transfer work to on the same system? Are your class structures such that you can just hand the data off? Are you using a data transform to map the critical data? Are you copying the attachment to the new item or moving it over? I've never actually done this, but my guess is that you're not managing the link attach table data and possibly other elements correctly. I'd probably start by tracing the attachment of a similar file so that you can map out all of the moving parts and then look at your transfer work process to see what else you need to do.
