Function Module to Call Adobe Form in Sap Abap

 To call an Adobe Form in SAP ABAP, you use a sequence of specific function modules: FP_JOB_OPEN to initialize the print/output job, FP_FUNCTION_MODULE_NAME to retrieve the name of the generated function module for your form, the generated function module itself to pass data and generate the PDF, and FP_JOB_CLOSE to close the job.

Key Function Modules Sequence

FP_JOB_OPEN
• Purpose: Opens the print or output job and configures output parameters (such as preview, no dialog, or printer destination).
• Key Parameter: IE_OUTPUTPARAMS (Type: SFPOUTPUTPARAMS / SFP_OUTPARAMS).
FP_FUNCTION_MODULE_NAME
• Purpose: Looks up the runtime name of the generated function module associated with your Adobe Form name.
• Key Parameters:
  • I_NAME (Passing your Adobe Form name)
  • E_FUNCNAME (Importing the resulting generated function module name) 
Generated Function Module (Dynamic Name)
• Purpose: Executes the form routine, processes the interface data, and returns the PDF output.
• Key Parameters:
  • Exporting: /1BCDWB/DOCPARAMS (Type: SFP_DOCPARAMS for language, country, etc.)
  • Importing: /1BCDWB/FORM_OUTPUT (Type: FPFORM_OUTPUT containing the generated PDF XSTRING)
  • Plus any custom importing parameters defined in your Adobe Form interface. 
FP_JOB_CLOSE
• Purpose: Closes the print job and finalizes the spool request or output generation.

* 1. Set output parameters (e.g., no dialog, enable preview or PDF get)
ls_outputparams-nodialog = 'X'.
ls_outputparams-getpdf   = 'X'. " Use if you want XSTRING PDF back in ABAP

* 4. Call the generated function module
CALL FUNCTION lv_fm_name
