Set the first two properties, if not work add the 3rd property it will fix
Step 1 : enable on the report
mxe.doclink.defaultPrintDocWithReport
use to set the default checkbox when attaching the attachment for default printable
mxe.directprint.inherited.attachment
also add the printable document which comes from PM or SR
mxe.report.AttachDoc.validateURL
Have you tried setting the mxe.report.AttachDoc.validateURL to false? This has fixed a lot of attachment issues for us.
