Use

When using interactive forms, a PDF document is usually created and sent to the client before the form is displayed by Adobe Document Services for the first time. For the rest of the Web Dynpro session, only the form data is exchanged between browser and server.

In special cases however, the complete PDF document must be sent between the browser and server during the Web Dynpro session. This is bad for performance since it increases the network load and the form data now has to be extracted from the PDF document by Adobe Document Services in an additional step.

Using Digital Signatures

The complete PDF document also has to be sent between the client and server when using digitally-signed PDF documents.

Binding the pdfSource Property

Only bind the pdfSource property if you want to continue to process the PDF document in your application (for example to save it in the database). In this case, the PDF document must be rendered again by Adobe Document Services for each roundtrip ( submit).
