ABAP Utility : Print-Screen to HTML

The Problem

: I need to develop a tutorial to be published on my personal website. Unfortunately, my personal website
being free-hosted, can’t afford heavy images generated
using print-screen for Z transactions. It should work on MiniSAP – SAP Release 6.10 (Basis/ABA) [ Who cares

about the rest of the world ???? ]
Other Benefits : Unlike print-screen

• • HTML pages are scrollable and light.
  • Also there will not be any resolution related problems as in case of images.
  • Users can cut & paste the data from HTML Screen , if required.
  • The downloaded SCREEN-HTML can be used for documentation
    purpose and for sharing it over the web.
  • At times SAP Users demand for exact Print of Screens
    rather than a List. This utility, being generic, can be
    used to enable PRINT facility for simple transactions.

 

Requirement

: The attempt is to provide
“Print-Screen to HTML” functionality for simple SAP
Transaction Screens .
This function module can be called
at ‘Print’ command for the current screen.
It will generate a HTML file to display simple SAP
Transaction screens ( Fields with Contents ) as HTML.
The functionality should be generic in nature and
re-usable for other transactions.
 

Processing :

• 2. The function module Z_RMTIWARI_PRINTSCREEN_TO_HTML is called, in the PAI of the screen to be printed,
     at command for ‘Print’.
     

CASE sy-ucomm.
*…….
WHEN ‘PRINT’.
data : lv_program type sy-repid,
lv_dynnr   type sy-dynnr.

lv_program =  sy-repid.
lv_dynnr   = sy-dynnr.

CALL FUNCTION ‘Z_RMTIWARI_PRINTSCREEN_TO_HTML’
EXPORTING
PROGRAM       = lv_program
DYNPRO        = lv_dynnr.

• …….

 

•     ENDCASE.

 

• 1. This FM ‘Z_RMTIWARI_PRINTSCREEN_TO_HTML’
     first generates HTML code for a blank
     screen-display of current screen. This is achieved by
     submitting a program Z_RMTIWARI_PRINTSCREEN_TO_HTML
     which in turn calls FM ‘RS_SCRP_PRINT_IN_LIST’
     for the transaction screen. The program generates a
     spool for a simple list of the blank Screen [ Only the field name
     and blank input/output fields ].
  2. This list will be read using FM LIST_FROM_MEMORY. Further, it will be converted into HTML.
     Also the field-values needs to
     be supplemented in the subsequent processing.
  3. FM ‘WWW_HTML_FROM_LISTOBJECT’ is used to convert List to
     HTML and further actual field values, retrieved using
     ‘DYNP_VALUES_READ’, are imposed on the generated
     HTML and downloaded to the local folder. The final HTML file displays a screen similar to
     SAPGui Xn screen including the field values.

 

Result :

It seems IFRAMEs can’t be used here. Also, I tried pasting the html code directly but SDN’s weblog is not able to show it properly. So no other go…
