A very common requirement for programmers writing ABAP code for printing using SAPScript Forms is to redirect output to a PDF (Adobe Acrobat) file. I struggled for a few days trying to find a solution to this. Though I found quite a few examples on the web, it was difficult figuring out which technique was optimal. This tip is borne out of these struggles.

This is an example of how to use ABAP code to save output of a print routine using a SAPScript form into PDF format and also display it within the SAP frontend itself. This routine proves extremely useful to provide users the ability to save local copies of output and preview it within the user-friendly Acrobat Reader control, all without leaving the SAP frontend or your program. Since function modules are used, the code is portable and this technique can be used in any other ABAP program as well.

Two function modules, Z_DS_CREATE_LOCAL_PDF_FILE and Z_DS_CALL_PDF_VIEWER need to be created. I have used a function group called Z5_DS_PDF for this purpose. The function group contains the ABAP objects code for declaration and implementation of a class that encapsulates the Acrobat application functionality. The function group also contains a screen '0901', that epresents our PDF viewer and one PBO and one PAI block for the same screen.

Note: The following example has been stripped of essential error-handling for the sake of simplicity and the programmer is assumed to possess knowledge of creation of function groups, function modules, screens and SAPScript forms. ABAP objects or custom controls knowledge is not mandatory. Be patient when trying this out and follow all instructions thoroughly. The results will be worth the effort.

Steps to follow to get this example running:<...

br> 1) Create a function group (Example : Z5_DS_PDF)
2) Define the top include and place the code listed below into it (LZ5_DS_PDFTOP)
3) Create screen '0901' in function group with three elements:
a) Pushbutton CLOSE at the top with function code 'CLO' (this is to exit preview screen)
b) Custom control container (Large- spanning entire screen) named MY_CONTAINER
c) The customary OK code field called OK_CODE
Note: The names of the elements should be exactly as described above
4) Create one output and one input module in the flow logic of screen '0901' for which the code is provided below
5) Define two function modules with the following signatures:

a) FUNCTION Z_DS_CREATE_LOCAL_PDF_FILE
EXPORTING
REFERENCE(AFILENAME) LIKE RLGRAP-FILENAME
TABLES
OTF_LINES STRUCTURE ITCOO

b) FUNCTION Z_DS_CALL_PDF_VIEWER
IMPORTING
VALUE(FILENAME) TYPE STRING
Code is provided below.

6) Compile and activate the function group
7) Create a simple SAPScript form with one page and one window
8) Define one element in the text for the main window called 'HELLO' and some static text in it
9) Check and activate the form
10) Create the example program (Example : Z5_DS_SCRIPT2PDF) with the below code
11) Run the example

NOTES: I tested this code in R/3 version 4.6C but it should work in all 4.6 setups. I'm pretty sure some of the ABAP objects code I have used may not work with R/3 4.0 versions and earlier. Also, it works perfectly only when Acrobat Reader is installed on the presentation server. I have checked it with Acrobat versions 4 and 5 but I haven't had the opportunity to check it with Acrobat Reader 6.
