Generating PDF in Web-Dynpro

[#1]

Hello,

I have a problem with generating a PDF file with ABAP WebDynpro. I have an ALV and there I read a line. From this line I want to build a smartform which should be converted into PDF. I think my coding works. I have no syntax errors and when I debug the coding, everything looks good. I also get my popup that I want to have. But then I got an error: "File does not begin with '%PDF-'."

I look for this error here in SDN but I could not find a solution. I have also tried to do what is mentioned in note 1042424.

Can anybody helps me?

Regards, Markus

Sebastian, thanks for your help, but I have used the funtions you have written.

I summarize my coding:

      others                        = 3.

In order to analyize that issue, please tell, if the pdf binary is created.

Does pdf_data have any value?

If not, does lt_otf any data.

That gives a hint, if webdynpro or smartform is the problem.
