Smartform OTF data table always empty

Hi,

Whenever I call the below function the OTF table in the job_output_info is always empty. This means I can't proceed to calling FM 'CONVERT_OTF' for convering to PDF.

All the other XML output tables are populated correctly and smartform can be sent via e-mail.  I have seen a good few threads here, some people have said they've solved it themselves without giving the solution, and I saw one that said the Smartform attributes needed to change? I thought setting the getotf flag to 'X' was all I needed.

Any ideas would be greatly appreciated. Thanks
