Attachment to Sales order Item Text

Dear All,

I have two questions.

1. In a salesorder --> Item line text --> Say, Material Sales text, using the "Load Local File" icon , is it possible to add attachment? When we have a text file, and use this ICON, it copies the contents of the text file. But I have a excel and I want to add this as an attachment/copy the contents of the excel to the material sales text. Is this possible? When I try to do this, it copies some junk characters but not the actual contents.

2. In the Salesorder --> Item line text --> Material Sales text, I will have a default text. But if I try to change the contents of the text, I should throw a warning message. As this is a text field, CDHDR /CDPOS tables will not be populated for this. Any idea how I can achieve this?

Any pointers are highly appreciated. Thanks for your help.

Regards,

Suganya
