Hi Rayden,

Can you give me the table name which contains the fields that you are talking about ( Name & Contact number ) So that i can write the code and send.

Check the below code.

tables: t001k.

For Identification Number

DATA: BEGIN OF it_bwkey OCCURS 0,

bwkey LIKE t001k-bwkey,

END OF it_bwkey.

data: v_bukrs(4).

For Run date

DATA: BEGIN OF it_bukrs OCCURS 0,

bukrs LIKE t001k-bukrs,

END OF it_bukrs.

DATA it_ret LIKE ddshretval OCCURS 0 WITH HEADER LINE.

SELECTION-SCREEN: BEGIN OF BLOCK main WITH FRAME TITLE text-001.

SELECTION-SCREEN SKIP.

PARAMETERS: p_bukrs(4) TYPE c.

SELECT-OPTIONS s_bwkey FOR t001k-bwkey NO INTERVALS.

SELECTION-SCREEN END OF BLOCK main.

good

You can call dialog modules in the POV event using the event keyword PROCESS ON VALUE-REQUEST.

PROCESS ON VALUE-REQUEST.

...

FIELD <f> MODULE <mod>.

...

After the PROCESS ON VALUE-REQUEST statement, you can only use the MODULE statement together with the FIELD statement. When the user chooses F4 for a field <f>, the system calls the module <mod> belonging to the FIELD <f> statement. If there is more than one FIELD statement for the same field <f>, only the first is executed. The module <mod> is defined in the ABAP program like a normal PAI module. However, the contents of the screen field <f> are not available, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. You can now program your own value lists in the module. However, this procedure is only recommended if it really is not possible to use a search help. Defining search helps is much easier than PROCESS ON VALUE-REQUEST, since the system takes over some of the standard operations, such as getting field contents from the screen. It also ensures that the F4 help has a uniform look and feel throughout the system. Furthermore, it means that you do not have to reassign input help to fields on each screen.

Hi Velangini Showry Maria Kumar Bandanadham,

My Table is ZSTUD00. I doing on dialog scrren and not selection screen. Both my Name and contact field is "Get From Dictionary" using Graphical Screen Painter. So do i go about it? Is there anyway that i can do with less coding?

Hi Rayden,

Eventhough it is dialog program you have to use the same logic which i gave.

Instead of parameter you can give the screen-field. Try replace my code with your table and fields.

Re: How to do Process on Value?

Former Member — Thu, 27 Sep 2007 11:34:40 GMT

Hi Rayden,

Replace 'INPUT FIELD for NAME' and 'INPUT FIELD for NUMBAR' with your screen fields.

And make sure that your table fields are correct as i took name for name and number for number. you can replace the fields with exact names from the table

ZSTUD00.

Check the below code

*Flow logic

PROCESS ON VALUE-REQUEST.

FIELD 'INPUT FIELD for NAME' MODULE get_valid_name.

FIELD 'INPUT FIELD for NUMBAR' MODULE get_valid_number.

*main program

internal tables

data: begin of it_name occurs 0,

name like ZSTUD00-name,

end of it_name.

data: begin of it_number occurs 0,

name like ZSTUD00-number,

end of it_number.

TABLES: t130r.

DATA: BEGIN OF dynpfields OCCURS 0.

INCLUDE STRUCTURE dynpread.

DATA: END OF dynpfields.

***********************************************

Select name from ZSTUD00 into table it_name.

if not it_name[] is initial.

sort it_name by name.
