MM Contract(ME31K) Attachment with name of the attachment

Hello Experts,

I am trying to attach documents to the MM contract using the transaction ME31K with attachment document name but I unable to achieve this.

In OAC0/OAC2 we can configure type of document.

And attachment can be done using  create->Store business document and drag and drop.

When I see the attachment list I could see only attachment list but I want to maintain the file name as well.

Anyone worked on this scenario?

Please help me.

Regards,
