Delivery manual attachment is saving as .txt instead of .pdf (archived document are okay) in WebGui

[GRI]

Hello,

My delivery has two attachment, one created by an output in archive mode ("Bon de livraison"). Other one, i added myself with VL02N, it's a classic PDF file ("croix").

When with webgui I try to display them, both looks like same.

But then I try to save them, "Bon de livraison" let me save in pdf format whereas "croix" save a txt file.

I found this note: https://me.sap.com/notes/2404718 but i dont want to prevent display pdf in browser given that it works for "Bon de livraison".

If you have any idea why behaviour differs.

Thanks, and best regards.
