Rebate agreements - Attachment icon not appearing

Hii There

Once we go to transaction VBO2, to change rebate agreements and enter into rebate payments and go to rebate documents

(VBO2 > Rebate payments >Rebate Documents-->Services for objects)

When we go to services for objects there used to be attachments icon on services for objects which has disappeared offlate on our system.

If someone has idea for this issue pls do reply back

Thanks & Regards
