User Defined Conversion Exits

This post will show how to create custom user defined Conversion-Exits.

Step 1) Create a Function Group and two Function Modules:

a) Create a Function Group. For eg. ZCONVERSION_EXIT.

b) Create two Function Modules with naming convention:

CONVERSION_EXIT_xxxxx_INPUT and CONVERSION_EXIT_xxxxx_OUTPUT, where XXXXX is the name of the Conversion Routine. Here I will create a Routine ZZERO so the
name of the Function Modules will be CONVERSION_EXIT_ZZERO_INPUT and CONVERSION_EXIT_ZZERO_OUTPUT. While create the Function Module you may get some error like "Function Module name is reserved for SAP", you can ignore this.



The Function Modules should have one Import Parameter Input and one Export Parameter Output.

The FM for conversion from External Format to Internal Format:



The Code:

*"----------------------------------------------------------------------
*"*"Local Interface:
*"  IMPORTING
*"     REFERENCE(INPUT)
*"  EXPORTING
*"     REFERENCE(OUTPUT)
*"----------------------------------------------------------------------

output = input.
REPLACE ALL OCCURRENCES OF 'Ø' IN output
WITH '0' IN CHARACTER MODE.

ENDFUNCTION.

*"----------------------------------------------------------------------
output = input.
REPLACE ALL OCCURRENCES OF '0' IN output
WITH 'Ø' IN CHARACTER MODE.

ENDFUNCTION.


Step 2) Create a data Element and a Domain.

Create the Data Element ZZERO:



The Domain ZZERO:



The name of the conversion routine created has to provided here. Now if the FM's for Conversion are created, if you double click on the Routine name, it will display the FM's.



Step 3)Now we can use a sample code to test the Conversion Routine:
The Code:

*& Report  ZTEST_CONVERSION_EXIT
*&
*&---------------------------------------------------------------------*
*&
*&
*&---------------------------------------------------------------------*

REPORT  ztest_conversion_exit.


PARAMETERS: p_value TYPE c LENGTH 20 OBLIGATORY.

DATA: v_result TYPE zzero. " data type with the Coversion Exit ZZERO

v_result = p_value.

WRITE: /5 'Input:',22  p_value,
      /5 'Converted Value:',22 v_result.


Now test it, If we give an input as "345RGT00VDF4340".



When Executed:



The "0" has been replaced by "Ø"

Similarly the Input Conversion Routine can be used and tested.

Traffic Light in ALV Reports

Many a times we have to display a traffic light in ALV report. We can do that easily using "Exceptions" parameter provided by SAP. But it has one drawback, we cannot change the column header to something meaningful. It always set as "Exception" in case of ALV Grid and an icon in case of ALV List.

Here I'll show a workaround to show the traffic lights with a meaningful column header.

The exception display:


















The workaround is to use a field of type CHAR4 and display it as Icon.
To display a field as icon, in ALV Field catalog we have to mark ICON field as 'X'. The icons for traffic lights are : icon_green_light, icon_red_light and icon_yellow_light.

Demo program for TOP-OF-PAGE for ALV displayed through CL_GUI_ALV_GRID

This program demonstrates how to create TOP OF PAGE for an ALV grid displayed through CL_GUI_ALV_GRID. One interesting fact which may be considered here is that the splitter TOP-OF-PAGE is not called while printing or background spool and the TOP-OF-PAGE printed in the spool cannot be displayed in the foreground.

The TOP-OF-PAGE displayed in foreground (this TOP-OF-PAGE won't be printed):
