UDF code:

1. String attachmentID =null;
2. GlobalContainer globalContainer = container.getGlobalContainer();
3. InputAttachments inputAttachments = globalContainer.getInputAttachments();
4. if(inputAttachments.areAttachmentsAvailable())
5. {
6. Collection<String>CollectionIDs= inputAttachments.getAllContentIds(true);
7. Object[] arrayObj =CollectionIDs.toArray();
8. attachmentID =(String)arrayObj[0];
9. Attachment attachment = inputAttachments.getAttachment(attachmentID);
10. int attachmentsize = attachment.getContent().length;
11. return"Attachment Name : "+attachmentID +" Attachment Size : "+attachmentsize+" bytes";
12. }
13. else{
14. return"no attachment found";
15. }

I am not able to get the same attachment name in the receiver and format too.

My source attachment name is : 2365727_E_20181219.pdf and

Target attachment name i am getting is like this. cid%3Aatt-43c91c58158811e9aeb9000000622a47@sap20190111-100422-352.com.

Please help on fixing in this issue.

Thanks in Advance.
