I am working on a program to send an email with an attachment from an SAP ECC6 Unicode system. I have used this same program in other versions of SAP, including ECC6, without a problem. Currently it uses the function so_object_send. But I have also tested using the class and methods for cl_bcs as well as function so_new_document_att_send_api1. All have the same issue where the attachment is corrupted. Instead of seeing the binary data for a pdf or tif. It looks like every other character within the attachment is a null or space. Has anyone else seen this happen with email attachments? Any help is greatly appreciated.
