For Refreshing a table display in ALV when data is chngd in maintainance vi

Hi All,
I am displaying the fields of a Ztable in a ALV report. A maintainance view call button is attached to that report through which data of Ztable can be changed.Prolem is that when after changing the data when I return back to report, changes are not reflected.
Kindly suggest to solve this problem.
I am using ALV display through class.
I have already used these functions in the else condition of IF GO_CUSTOM_CONTAINER IS INITIAL.
CALL METHOD go_grid->refresh_table_display.
CALL METHOD cl_gui_cfw=>flush.
For maintainance view I am using the function as
VIEW_MAINTENANCE_CALL on double clicking the maintain button.
Kindly suggest.

Ashutosh,
Just calling the REFRESH method will not work. You need to re-fetch the data into the same internal table which you using the displaying the data in the grid.
Probably you can write this data fetching as a subroutine and call this as soon as come back from the Maintenance screen. And updating the internal table, call the REFRESH method.
This should work.

Ravi

My Initials for Game Center are displaying as DC when they should be NC how do I change them ?

My Initials for Game Center are displaying as DC when they should be NC how do I change them ? This makes it confusing for people to add me and is an annoyance please help.

That's because you scanned them as B/W photos and iPhoto 08 doesn't support the grayscale color profile. You can either rescan them as color photos or export them as originals out of iPhoto to a folder on the desktop and applhy this Automator application, Convert to JPG and Embed sRGB Profile, on them and then remimport into iPhoto. You can download it from Toad's Cellar . Be sure to read the warning on the website about not applying it on your only copies.

No column text displayed in alv when i use dynamic internal table

Hi friends,
when I use dynamic internal table to display the fields in ALV formant, field column text was not displaying ,
total row of column text was blank.
can u sujjest me in this...
with regards,
prasad.

Hi
That depends on how you've filled the catalog table, here u need to insert the description for the labels (short, medium and long) and the description for the layout variant management.
So u make sure to fill the fields like
SCRTEXT_L
SCRTEXT_M
SCRTEXT_S
REPTEXT

Totals for the internal table field in alv

Hi Gurus,
I have an issue in displaying the totals in alv.
I have an internal table with the three fields like below.
scrap_code_001 like afru-xmnga, " Scrap Reason Qty.
scrap_code_002 like afru-xmnga, " Scrap Reason Qty.
scrap_code_003 like afru-xmnga, " Scrap Reason Qty.
In the output table which i am passing to the fieldcatlog is having the three above fields with values 10,3,4 respectively.
I am looping at the internal table
loop at gt_grund.
gv_tabix = sy-tabix.
i_fieldcat-no_zero = gc_x.
i_fieldcat-do_sum = gc_x.
perform assign_alv_qty_format.
if gt_grund-grund is initial.
gt_grund = 'NONE'.
gv_text = gt_grund.
else.
gv_text = gt_grund-grdtx.
endif.
gv_tabixn = gv_tabix.
gv_scrap_code+11(03) = gv_tabixn.
gv_fieldname = gv_scrap_code.
translate gv_fieldname to upper case.
perform bild_fieldcat using
gv_fieldname 'GT_REPORT' 'AFRU' gv_text 'QUAN' '12' ' ' .
endif.
endloop.
But in the output I am getting the totals but it displays totals for all the three columns as 17,17,17 (summing 10,3,4).
How do I display total as 10,3,4 for each column separately.
I appreciate you help and award points for the answer

Hi,
Please check if value fields i_fieldcat-ref_fieldname and i_fieldcat-ref_tabname regard to numc or curr type.
EX: i_fieldcat-ref_fieldname = 'WRBTR'
I_fieldcat-ref_tabname = 'BSEG'.

Regarding table display in ALV header

Hi,
I have a requirement please check the attached jpeg file.
Could any say how can i proceed with the layout to be displayed in the ABAP Report output.

Hi Goutham,
Use system fields SY-VLINE and SY-ULINE for designing output.
Here is one simple example to make you understand.
Classical report with sort option - Code Gallery - SCN Wiki
You can search for many examples in scn search also.
You have to put some of effort to achieve your design, but it is can be done using classical reporting.

How to display success message when data is changed in the custom tab in MM

Hi,
I have added a new custom data tab in the MM01/MM02/MM03 transactions. Whenever I do changes to fields in the custom tab in MM02 transaction, and no changes in the standard tabs, I will get a message stating "No Changes Made".
But if I do changes in the standard tabs, it works as usual with display of message "Changes to particular material has been done.
Please let me know, if anyone of you know, how to display the success message if the changes to the custom tab is done.
Thanks in advance,
sudhanva

Hi Sudhanva,
The exit EXIT_SAPLMGMU_0001 is a function exit that you can use for custom validation but not to add custom tab/screen.
But the message issued by SAP is not related to this Function Exit.
If you have used a Screen Exit, then there must be some Function Exits also in the same Enhancement using which you can assign the value of custom fields to/from the standard structure. Thus when the value of any custom field is changed the system can understand that the some changes have been changed and will not issue the message.
In case you have used a BADI, there can be other methods in the BADi using whcih you can assign the value of custom fields to/from the standard structure. This might also prevent the message from being displayed.
I could try giving you further details if you can provide the name of the Enhancement/BADi that you used to add the additional tab.
Hope this helps.

Abhisek.

Table display in Selection Screen

In upper part of selection screen, there would be 2 parameters.
In lower part of selection screen, there would be 2 table display side by side. Data of these two tables can be changed from here.
Parameters are not related with tables data.
After executing the program, all the data from those Database table will be shown into selection-screen's individual table area.
After changing data, while click to 'save' button, changes would reflect into database.
Can any one please help on this matter?

HI,
You can do in the following way.
You have to create a different screen for holding the table control.. When the checkbox is ticked just call the screen using CALL SCREEN or LEAVE SCREEn in your program which will display your table control.
or else
Go with module pool program.
Design the screen as your requirement.
Under PBO write the bleow code.
Create a module like MODULE_DEACTIVATE_TC.
write the below code to invisible TC initially.
IF CHECKBOX IS INITIAL.
LOOP AT SCREEN.
IF SCREEN-NAME = 'TC'.
SCREEN-INPUT = '0'.
SCREEN_INVISIBLE = '1'.
MODIFY SCREEN.
ENDIF.
ENDIF.
Create module inder PAI,to acivate TC
MODULE ACTIVE_TC.
inside module write bleow code.
IF CHECKBOX EQ 'X'.
LOOP AT SCREEN.
IF SCREEN-NAME = 'TC'.
SCREEN-INPUT = '1'.
SCREEN_INVISIBLE = '0'.
MODIFY SCREEN.
ENDIF.
ENDIF.

Need Help in Field Symbol for Dynamically passing table field value

Hi All,
In my internal table I am having data.
I am dynamically forming table field name and substitute for the another table field name to pass DATA.
but I am getting the Variable name insted of Value ie Data.
I am using Field Symbol for this.
data:
Field-symbols <TS> type any.
field1 type string.
LOOP AT TABLEFIELDS INTO WA_TABLEFIELDS.
            READ TABLE TEST WITH KEY NAME = WA_TABLEFIELDS-FIELDNAME.
            IF SY-SUBRC = 0.
              CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
              Assign Field1 to <TS>.
                ALL_VAL-VALUE = <TS>
"After substituting the <TS> into ALL_VAL-VALUE field I need a DATA to be passed but the variable name is appending"*
         APPEND ALL_VAL.
            ENDIF.
          ENDLOOP.
kindly how to pass the value into the table.
Thanks in advance.
San

Hi,
pls assign a break point in
CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
Assign Field1 to <TS>.
ALL_VAL-VALUE = <TS>
   " Put a break point here and check for the value in <TS>.
if <TS> contains value then create a work area for ALL_VAL AND PASS the Field-Symbol to that and then append thw wa into the table...
Hope this works out!!
thanks

Default partition name for Interval partitioned tables

Hi ,
Can we change the default partition names which are generated by Oracle.
For Example :
CREATE TABLE part_interval (
id NUMBER,
created_date DATE
PARTITION BY RANGE (created_date)
INTERVAL (NUMTOYMINTERVAL(1,'MONTH'))
PARTITION part_01 values LESS THAN (TO_DATE('01-NOV-2007','DD-MON-YYYY'))
Now if I insert values which doesn't fall in the 01-NOV-2007 date, a new partition is created like SYS_P43. Can I change this default partition name in the SQL statement itself . Not through procedures or functions.
Regards,
Raghunathan A

Help on ALV GRID display outputting format for 2 internal tables

Hi,
    I have requirement in ALV GRID where I need to display the data from 2 internal tables. The first internal table has the content of Delivery due list data and second the internal table has the corresponding stock transfer data of the Delivery Due list. I have a checbox on my selection screen, when unchecked it should output the 1st internal table data, i.e for Delivery due list. When it is checked then it should output 1st Internal table data + 2nd internal table data of stock transfer. For example, 1 document delivery due list data and 2nd line for that document should show the stock transfer data. You can also check the transaction code VL10E for that will show a delivery due list...and for stock tranfer,you need to check with Purchase order in in the USer Role tabstrip. Pls suggest.

Table Display in for OO ALV Grid

Hello All,
I have an internal table with the following setup:
DATA: BEGIN OF mat_locs OCCURS 0,
          matid      LIKE /sapapo/matloc-matid,
          locid      LIKE /sapapo/matloc-locid,
          pegids     TYPE /sapapo/om_pegid_tab,
       END OF mat_locs.
The PEGIDS is a Table of GUIDs. It is possible that the PEGIDS table can have more than one entry for each MATID and LOCID. Currently, I am only able to have one line item appear in the ALV grid when there are two in PEGIDS. Is there a setting that I am missing to display this correctly? Thanks for your help in advance.
John

Hi,
I am not sure how to display second level internal table in an ALV grid..
But I can suggest you one thing..
Create an internal table with the following fields..
DATA: BEGIN OF ITAB OCCURS 0,
        matid LIKE /sapapo/matloc-matid,
        locid LIKE /sapapo/matloc-locid.
        INCLUDE STRUCTURE /sapapo/om_pegid. "GIVE THE STRUCTURE and not the table type..
DATA: END OF ITAB.
Populate the data..
Create a sort order for the fields matid & locid..And then display the records..
Thanks,
Naren

Refreshing ALV when action is triggered using button

Hello Friends,
I have a drop down list having 3 values "Last 30 Days", "Last 60 Days" and "Last 90 Days". If I select Last 30 Days and click on button "Search" it gives me record for the last 30 days. But, if I click again on "Last 60 Days" it duplicates the record that was already in. So it does not refresh the previous result. I have added the code as below to refresh ALV but, it refresh the table but not the ALV. My View name is "MY PO INVOICES" and the context node name is 'MY_PO_INV' .
DATA ln_node type REF TO if_wd_context_node.
ln_node = wd_context->get_child_node( 'MY_PO_INV' ).
ln_node->invalidate( ).
Please let me know how do I refresth the result in the ALV display when I trigger the event.

Hello All,
Thanks very much for your responses. I tried to bind the alv table. But, I think I am doing some thing wrong here. Below is my code. Please let me know where I am doing wrong. Appreciate your help.

lv_ninetydays = 'LAST 90 DAYS'.
if ZDAYS = lv_thirtydays.
      lv_zpostingdate = sy-datum - 30.
      ENDIF.
lv_zpostingdate_to = sy-datum.
    if ZDAYS = lv_sixtydays.
       lv_zpostingdate = sy-datum - 60.
   ENDIF.
    if ZDAYS = lv_ninetydays.
       lv_zpostingdate = sy-datum - 90.
   ENDIF.
ln_node = wd_context->get_child_node( 'MY_PO_INV' ).
ln_node->invalidate( ).
