Download Adobe Form Using SAP NW Gateway

Steps-

Create Adobe Form

First, Develop Adobe Form using Tcode SFP ZF_AdobeForm, which will have input as docparams and will export formoutput.

You can follow step to create Adobe Form as per requirement

Create Project and Entity Type

Now develop GW service which will help us to expose Form. Create simple GW service ZFORM as displayed below.

We have Entity Form (Media Type) and Entity Set Forms.

Generate run-time artifacts.

Redefine Define method marking Mime Type

Now we need to redefine DEFINE Method in MPC_EXT class as below.

METHOD define.

  DATA:

lo_entity   TYPE REF TO /iwbep/if_mgw_odata_entity_typ,

lo_property TYPE REF TO /iwbep/if_mgw_odata_property.

super->define( ).

lo_entity = model->get_entity_type( iv_entity_name = ‘pdf’ ).

  IF lo_entity IS BOUND.

lo_property = lo_entity->get_property( iv_property_name = ‘mime_type’ ).

lo_property->set_as_content_type( ).

  ENDIF.

ENDMETHOD.

Redefine GET_STREAM

Redefine method /iwbep/if_mgw_appl_srv_runtime~get_stream in DPC_EXT as below.

METHOD /iwbep/if_mgw_appl_srv_runtime~get_stream.

     DATA: lv_funcname     TYPE funcname,

           ls_outputparams TYPE sfpoutputparams,

           ls_docparams    TYPE sfpdocparams,

           ls_formoutput   TYPE fpformoutput.

     DATA: ls_stream   TYPE ty_s_media_resource.

     ” Getting the Function Module Name for the Adobe Form

     TRY.

         CALL FUNCTION ‘FP_FUNCTION_MODULE_NAME’

           EXPORTING

             i_name     = ‘ZF_AdobeForm’     “Adobeform name

           IMPORTING

             e_funcname = lv_funcname.

         “Handle Exceptions with Try – catch

     ENDTRY.

     ” Opening the Job

     ls_outputparams–nodialog = abap_true.

     ls_outputparams–getpdf   = abap_true.

     CALL FUNCTION ‘FP_JOB_OPEN’

       CHANGING

         ie_outputparams = ls_outputparams

       EXCEPTIONS

         cancel          = 1

         usage_error     = 2

         system_error    = 3

         internal_error  = 4

         OTHERS          = 5.

     IF sy–subrc <> 0.

* Implement suitable error handling here

     ENDIF.

     ls_docparams–langu = sy–langu.

     ls_docparams–country = ‘US’.

     CALL FUNCTION lv_funcname

       EXPORTING

         /1bcdwb/docparams  = ls_docparams

       IMPORTING

         /1bcdwb/formoutput = ls_formoutput

       EXCEPTIONS

         usage_error        = 1

         system_error       = 2

         internal_error     = 3

         OTHERS             = 4.

     IF sy–subrc <> 0.

* Implement suitable error handling here

     ENDIF.

     ” Closing the Job

     CALL FUNCTION ‘FP_JOB_CLOSE’

       EXCEPTIONS

         usage_error    = 1

         system_error   = 2

         internal_error = 3

         OTHERS         = 4.

     IF sy–subrc <> 0. ” Subrc Check is not required, so we are not handling any exception here

     ENDIF.

     ” Converting the PDF to XString

     ls_stream–value = ls_formoutput–pdf.

     ls_stream–mime_type = ‘PDF’.

     copy_data_to_ref( EXPORTING is_data = ls_stream CHANGING  cr_data = er_stream ).

ENDMETHOD.

Testing the Service

Register GW service, and we are ready for testing.

To read document a GET containing the keys with $value to read stream can be requested:

/sap/opu/odata/sap/ZFORM_SRV/Form(‘key value value’)/$value
