Supplier field
The values displayed under the Supplier field are the combined value of Partner Code and Partner Name records from the Partners module. This field is in read only mode when displayed and you can apply this to all document types. Every time a partner user uploads a document, the field is automatically populated with supplier information to which the partner user belongs to. If you or any internal user uploads a document, then the field is always set to blank. These fields and their values are saved by schema or by version.
When partner user uploads images or attachments to other areas in the application that supports the Supplier attribute feature, the documents will also show proper supplier tagging when they are viewed in the FPLM Document type of the Document Library.
