Hi,
I want to display image and relevant data besides the image in module pool screen, I am using docking container to display the image.
Actually I am able to display image or data any one but not both.
one more thing I want to display multiple images and their data.
Please suggest some one if you have any idea.

Please provide solution.
Thanks in advance.

This is the program where u can get the WA_THEAD from other program like report and trying to display and modifying that text. U can do instead of WA_THEAD u can generate here itself and use also

I have a screen with a custom container and I tried to call a TIF image from MIR4 which is in attachment list(which is stored in archived link).

I tried using below code

         container_name = 'CONTAINER'.
*    create object container_2
*      exporting container_name = 'PICTURE_CONTROL_2'.
     CREATE OBJECT PICTURE_CONTROL_1
       EXPORTING
         parent = container_1.
*    CREATE OBJECT PICTURE_CONTROL_2 exporting parent = container_2.

CALL METHOD PICTURE_CONTROL_1->set_display_mode
     EXPORTING
       display_mode = PICTURE_CONTROL_1->display_mode_fit_center.
But I am able to display this URL    = 'SAPR3://WebRepository/0020698212/DEMOWORD97SAPLOGO?Version=00000' and not able to display my archive link image which is in TIF.
note: Display image of Arc.link Doc.type ZBUSI_TIF (doc.class TIF)
Please help me on this.
Thanks
Geetha Charan

Hi sai,
Please refer th procedure.
For the select-options you might have defined a selection screen.
Next you can fetch the entire data that you wanted to display in a module pool into an internal table.
you can call the screen you defined for o/p upon the selection.
Then, You define a screen XXXX and a table control in the scree, and in the PAI module of the screen
you write a chain end chain processing in which you can display the contents of your internal table.
OR
if you want the selection also to be in the module pool, then for displaying the O/P you can definr a sub-screen of the initial screen and you can call that sub-screen on selcting, which can be done with a function code.
Hope this helps

Display Continuous Fluctuations in Input Data in Module Pool Screen

Dear All,
We are working on a Weighbridge Interface scenario, where the weighbridge is sending data to a digitizer, which is connected to the COM port of a PC. The objective is to read the data from the digitizer, and display in a Module pool screen. However, there is one more requirement: the weight may fluctuate until it stabilizes, and the fluctuations have to be displayed on screen. For example, the tare weight of a vehicle may be 12.4 TON, but when the vehicle is standing on the weighbridge, the weight may vary from 10.4 to 12.4 TON. The idea is to capture the stable weight, so that any discrepancies can be avoided. In the current IT system implementation, the fluctuations in the weight are displayed. But using ABAP, can these fluctuations be captured? For example, we may design a screen containing a field for capturing the weight, and the weight displayed there automatically refreshes as soon as there is a change in the digitizer reading. Is this possible to achieve? If so, how?
Awaiting answers.
Thanks and Regards,
Sid

Hi Sid,
just a suggestion for the refreshing of an ABAP screen: you can use class CL_GUI_TIMER, but it only handles whole seconds, i.e. 1 second, 2 seconds and so on, but not 0.5 seconds...
An example of an ABAP listing could be the following:
*& Report ZZAVV001
REPORT zzavv001 NO STANDARD PAGE HEADING.

        INCLUDE STRUCTURE bseg.

Okay, it's just a tiny code snippet, but I hope it may help you by designing auto-refreshing screens.

Icon display in Module pool screen not visible to some users

Hi,
I have added an icon in one of the module pool screen with dynamic quick info. The page is rendered fine and the info is also displayed well for most users except some. I can't figure out why the icon is not being displayed for some users.
Do someone has any solution for this?
Thanks,
Sumith

As I recall, the icons are actually stored in a file on each PC so some users may have a corrupted or out-of-date file with the icons. You can look for posting on "how to add an icon" to see a discussion on this topic.
I found some useful info at:
Create and Add Icons to table ICON?

Display Select option in module pool screen

What are the Function modules used to display Select option type fields in a module pool screen?

hi,
You can use the SELECT-OPTIONS statement to place a group of fields on the screen that allows users
to enter complex selections. The selection may be a single value, or any form of interval
Selection ranges are stored in programs using an internal table.
The ABAP statement SELECT-OPTIONS <selname> FOR <field> declares an internal table called
<selname>, containing four fields - SIGN, OPTION, LOW, and HIGH. The fields LOW and HIGH have
the same type as the field <field>.
The SIGN field can take the value 'I' (for inclusive) or 'E' (for exclusive).
The OPTION field can contain relational operators (EQ, NE, LE, LT, GE, GT), pattern operators (CP,NP), and operators that allow you to enter intervals (BT, NB).
SELECTION-SCREEN BEGIN OF BLOCK conn WITH FRAME TITLE text-001.
PARAMETERS pa_car LIKE wa_sflight-carrid OBLIGATORY.
SELECT-OPTIONS: so_car FOR wa_sflight-carrid,
SELECTION-SCREEN END OF BLOCK conn.
Hope this helps, Do reward.

Hi,
If you're using standard bapi's to save the material, you can then use either the standard events which are already triggered or you coul add a change document for material changes or creation.
Then this event can be the trigger of your custom workflow.

            view_name                    = 'Z_Table_Name'
       exceptions
            client_reference             = 1
            foreign_lock                 = 2
            invalid_action               = 3

How to get the Grand Total in Module pool Screen

Hi Frds.
     How to get the Grand Total in Module pool Screen
Example i have 10 different materials
for each matarial has different moving . But in my case matarials is doesnt matter here
10 material Moving Average price to do Frand total and display in one column...
Please Help me out Frds.
Regards,
Kabil

Hi
You need to calculate the total in a module of PAI (or PBO) event:
PROCESS PAI.
   LOOP.....
   ENDLOOP.
MODULE CALCULATE_TOTAL.
MODULE CALCULATE_TOTAL.
    GRAND_TOTAL = 0.
     LOOP AT ITAB,
        GRAND_TOTAL = GRAND_TOTAL + ITAB-PWB.
    ENDLOOP.
ENDMODULE.
In this way the grand total will be calculated as soon as the user presses enter or another command.
You can't insert the calculation in the loop of table control, because this loop runs the visible lines only, so it's better to calculate the total out of those loop,
