Attach a PDF (Scanned Document) to a Process Order

Hi,

Is there a way to attach a PDF file (scanned document) to a Process Order header? I tried to look at the document management config for this, but could not locate one. I also tried creating a new document type for Process Order, but not working.

The business requirement is that we get some hard copy documents from the floor containing critical information. They would like to scan this document and then attach it to the process order so that they can look at it later on whenever required for audit and other purposes by going to the process order.

Please advice how this can be done. Thanks in advance.

Regards,

Swapnil
