We are facing issue with the email attachment send in HTM format using FM SO_NEW_DOCUMENT_ATT_SEND_API1 in ECC 6.0 during upgrade from 4.7.
The program builds the attachment is binary format for document type HTM. In 4.7 system, When we view the send email in SOST, the attached document is off type RAW. If you double click the attachment it will be open up in SAP editor and Once you release the mails from the system the recipients will get the HTM attachment in mail.
But in ECC 6.0 Env the same program generates the email attachment but when viewed in SOST its of type HTM. If you double click the file will not open up. Also the main issue is that when this email is released the attached document is blocked by Outlook replace it with Trojan warning attachment.
Is this because of any missing config settings for document type.
When we modified the program to build the attachment in ASCII format, it turned out to be working similar to the 4.7 and mail where received correctly. We are not recommending this approach because there are quite a few program which is facing this issue and we end up modifying all.
I was suspecting there should be a config fix this issue.
Kindly provide you valuable inputs.
