The layout can currently be created as Web Dynpro for ABAP.

Initially, Adobe Interactive Forms was the rendering technology used in the Form Processing Framework.
As stated in the SAP note 1918612 - SAP IFbA: Information Reader/Browser support:
"SAP Interactive Forms by Adobe integrated in Web Dynpro is based on the Netscape Plugin Application Programming Interface (NPAPI) browser technology. The only browser that still supports the NPAPI today is Microsoft Internet Explorer. SAP announced to de-support IE11 for certain UI-frameworks."Additionally, as stated in this SAP note 2919999 - Support for InteractiveForms in Web Dynpro ABAP:
"Scenarios that are no longer supported must be reimplemented using other controls (Web Dynpro ABAP UI elements, HTML5, or third-party HTML5 products)."Therefore, Adobe Interactive Forms are not a possible form rendering technology anymore.
Web Dynpro for ABAP is another rendering technology that is also supported by the form processing framework.
Web Dynpro for ABAP is the SAP standard UI technology for developing Web applications in the ABAP environment.
It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
Rendering in UI5 technology is currently on the TRM roadmap.
Web Dynpro Component
To generate your form, you have to first create a Web Dynpro component for the Web Dynpro application and then assign it to the form type.

The steps are:
- Define an ISR scenario.
- Create a Web Dynpro component (copy of FMCA_WDY_FORM_UI_TEMPLATE or FMCA_WD_FORM_TAB_TEMPLATE) over to the Web Dynpro you want to create (for example, FMCA_WDY_FORM_UI_SUET).
- Run the report FMCA_GENERATE_WD_FORM_GUI and enter the name of the component you just copied.
- Specify the scenario data.
- Choose the options for updating the existing Web Dynpro component.
- Execute the program. The program then adds all the fields of the Internal Services Request and maps them to the corresponding Web Dynpro controllers.
- Assign your Web Dynpro component to the relevant form type. To do so, choose IMG activity Define Form Types.
If you have changed the names of characteristics used in a form, you can also use this configuration activity to update the existing Web Dynpro component.
