Attachment missing for Vendors

Dear Experts

We are using the following version of SRM

SRM 7.0, EP 7.3 with the classical scenario approach of SRM shopping cart.

During the Creation of shopping cart we are maintaining the attachments in the item level. The same attachments can be viewed in ECC against the PR number and then converted to PO. While sending the email to vendor, the mail doesn't have the attachments what we have maintained against the Item level. It shows only the PO PDF but not attachments.

Kindly let us is there any way to send attachment (which was maintained at the Item level) while sending the PO to vendor?

Kind Regards,

Hariprasath
