For historical reasons, forms can exist which were created based on obsolete integration technologies. There are also special cases which are only for SAP internal use.
ACF-based forms.
Caution
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.
Recommendation
You can find information about switching from ACF-based forms to ZCI in 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 the pdfSource for interactive forms and it is unreliable for ZCI-based forms (PDF-only scenario)
