For historical reasons, forms that were created based on obsolete integration technologies can exist. There are also special cases that are for SAP internal use only.
ACF-based forms
The integration of ACF-based PDF forms in Web Dynpro ABAP is deprecated. See also SAP Note 1249189 .
We expressly recommend only implementing ZCI forms with XML interfaces.
New Adobe standard objects are now only available for ZCI (Native) based forms.
For more information about switching from ACF-based forms to ZCI, see SAP Note 978037 .
Forms with ABAP Dictionary-based interfaces can only be used as print forms.
You can find further information about forms with ABAP Dictionary-based interfaces in SAP Note 1252350 .
We do not recommend binding thepdfSource for interactive forms and it is not permitted for ZCI-based forms (PDF-only scenario).
