Load PDF as template source for interactive forms based on given filename

My scenario is:

1. I fill out page 1 of a blank interactive form and digitally sign it. When I submit, it creates a PDF file named a.pdf on the server.

2. Then later on someone else wants to pull up that previously created PDF and fill out the 2nd page of the form and digitally sign it. (at this stage the form should have the information I filled out earlier.) When the form is submitted, it creates another PDF file.

I have been searching around it seems like if i have a web dynpro view I can pass a filename as a parameter to have the view show that PDF as an interactive form. However, I haven't been able to succeed.

Please help. thanks in advance.

    Hi Mick,

    I guess your scenario looks similar to upload/download tutorial given in SDN sample tutorials list.

    Just check that tutorial.

    • Hi Mick,

      I guess what you experienced would be the result of the lack of support for digital signatures. The only way to retrieve them - so to speak - in NW 04 is to keep the PDF and look at the signature's properties in Adobe Reader, which would tell you about the status of the document.

      You can use the PDF itself as the 'bearer' of information in such a workflow by using special SAP form objects form the Adobe LiveCycle Designer 7.0 Library palette (Web Dynpro tab). There is one called Sign&Lock, which allows you to have the first person fill in their fields and upon signing this part lock these field for further editing. Then the second person can add their part.

      Again, the signature information stays inside the PDF. While server-side signing was planned for NW 2004s (mySAP ERP 2005), there are a couple of issues that won't be fixed until the shipment of Adobe Reader 8 at the end of 2006, which means SAP will not recommend to use the dig sig functions before then. Further information will be available in an SAP Note.

      By the way, all available functions of the ADS are in the PDFObject documentation (in the javadocs in the Dev Studio or at https://media.sdn.sap.com/javadocs/NW04/SP12/webdynpro/com/sap/tc/webdynpro/pdfobject/api/IWDPDFObject.html).
