ALV - How to set selected rows into internal table

Hi all,
I am tying to set with an 'X' flag the selected rows in my ALV using an internal table that contains all rows showed.
More exactly I have tried to follow these steps.
1) I have added the filed SEL (type SEL) to my ALV structure zrt_bo_slabsend and I defined my internal table in this way
 DATA: gt_report TYPE STANDARD TABLE OF zrt_bo_slabsend,
 gw_report TYPE zrt_bo_slabsend.
2) I have set gw_layo-box_fname = 'SEL' to gw_layo (ALV layout)
Pressing the "delete button" that I have insert on the top of the ALV, I intercept correctly my user command and I call a form (named "delete_lines") where I have this abap code
FORM delete_lines.
 DATA: l_subrc LIKE sy-subrc,
 lw_grid_settings LIKE lvc_s_glay.
gw_layo-box_fname = 'SEL'.
 "set field name to store row selection
gw_layo-edit = 'X'. "makes whole ALV table editable
gw_layo-zebra = 'X'.
gv_repid = sy-repid.
call function 'REUSE_ALV_GRID_DISPLAY_LVC'
exporting
 i_callback_program = gv_repid
 i_callback_pf_status_set = gc_status
 i_callback_user_command = gc_user_command
 is_layout_lvc = gw_layo
 it_fieldcat_lvc = gw_fkat
 i_grid_settings = lw_grid_settings
 i_save = 'X'
 is_variant = variant
 it_events = gt_events
 TABLES
 t_outtab = gt_report
 EXCEPTIONS
 program_error = 1
 OTHERS = 2.
LOOP AT gt_report ASSIGNING <report> WHERE SEL = 'X'.
 DELETE gt_report.
ENDLOOP.
ENDFORM.
I'd like to select many rows in my ALV report, than by pressing the delete button I'd like to see a refresh of my ALV, without the selected rows. I want to save it only at the end of my action, only by pressing the save button.
Any suggestion about the abap code will be well appreciated.
Thanks in advance for your kind help.
Regards.
 Giovanni

Hi,
You need to use the method GET_SELECTED of IF_WD_CONTEXT_NODE to get the rows selected. Also ccheck for the paramters of that method, this retruns the element set.
This meets your requirement.

How to get all values in the range of select option into internal table?

Hi,
I need to capture all entries coming in the range of select option into one internal table.
How to do get that?
For E.g
select-options: matnr for mara-matnr.(select option)
IF I enter G0100013507892 as lower value of matnr and G0100014873947 as higher value
and if there are 10,000 materials in the above range, then I want to capture all theses 10000 materails in one internal table. How to do that?
Regards,
Mrunal

Hello Mrunal Mhaskar ,
What i understand you can do one thing go in debug mode
Try this code : -
LOOP AT s_matnr_ex.
IF s_matnr_ex-low IS NOT INITIAL.
    i_matnr-matnr = s_matnr_ex-low.
    i_matnr-option = s_matnr_ex-option.
    APPEND i_matnr.
    CLEAR : i_matnr.
ENDIF.
ENDLOOP.
LOOP AT s_matnr_ex.
IF s_matnr_ex-high IS NOT INITIAL.
    i_matnr-matnr = s_matnr_ex-high.
    i_matnr-option = s_matnr_ex-option.
    APPEND i_matnr.
    CLEAR : i_matnr.
ENDIF.
ENDLOOP.
In the i_matnr table high and low values are there.

How to control selected row in result table on a search page?

Using JDeveloper 10.1.3.2.0
I have attempted to create an ADF page that contains a search and result table in the same page.
I have questions related to the result table. Let's say the result table shows 10 rows per page.
If I page forward there is no default selected row "clicked" on the page. Only if you return to
the very first 10 rows do you see a default selection in row number one of the results.
How would I go about making the first row of each page the default selection?

You'll need to code this into the RangeChangeEvent event of the table.
http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/apidocs/oracle/adf/view/faces/component/core/data/CoreTable.html
That said - I'm not sure this will be very helpful for the end user - after all in any case they'll need to first select a row before doing an operation on it.

Select (join) into internal table with nested structures

Hello Experts,
i wonder about the correct notation of a select statement.
I have an internal table it_zoll including two structures as defined below.
The select is a join on the two tables zollp and zolls. As coded below the select is syntactically correct, but the fields
in the nested structures are not filled ....
Any ideas how to write the select statement ? (The internal table it_zoll must have the nested structures for other reasons ..)
Declaration:
TYPES: BEGIN OF ty_zollp,
belnr     TYPE zollp-belnr,
werks     TYPE zollp-werks,
gebnr     TYPE zollp-gebnr,
       END OF ty_zollp.
TYPES: BEGIN OF ty_zolls,
grnum     type zolls-grnum,
werks     type zolls-werks,
name1     TYPE zolls-name1,
       END OF ty_zolls.
DATA: BEGIN OF wa_zoll.
DATA: zollp type ty_zollp.
DATA: zolls type ty_zolls.
DATA: END OF wa_zoll.
DATA: it_zoll LIKE TABLE OF wa_zoll.
Select:
SELECT
    zollp~belnr   zollp~werks zollp~gebnr
    zolls~grnum zolls~werks zolls~name1
      FROM zollp
      JOIN zolls ON   zolls~werks = zollp~werks
                 AND zolls~grnum = zollp~grnum
      INTO CORRESPONDING FIELDS OF TABLE it_zoll
      WHERE zollp~werks = werks
      AND   zollp~gebnr IN s-gebnr
      AND ...
Thank you !

DATA: BEGIN OF ty_zollp,
belnr     TYPE zollp-belnr,
werks     TYPE zollp-werks,
gebnr     TYPE zollp-gebnr,
       END OF ty_zollp.
DATA: BEGIN OF ty_zolls,
grnum     type zolls-grnum,
werks     type zolls-werks,
name1     TYPE zolls-name1,
       END OF ty_zolls.
DATA: BEGIN OF wa_zoll.
Include structure ty_zollp.
Include structure ty_zolls.
DATA: END OF wa_zoll.
The above declaration had worked. Please try.

Improving performance:How to know selected rows in af:table through chk box

Hi,
I've a VO which has 3 transient variables. 2 of these transient variables getting the values from a view accessor. Using the other transient variable in the Ui to select the rows in the af:table.
In my UI, I've a table and a Check Box to select the rows. I want to get the selected rows through the check box, in the backing bean for my business requirements.
I've used below logic to get the selected rows. Here, I am iterating through the entire viewobject rows, so it is impacting the performance of the UI. How can I know the selected rows in the bean? or How can I improve the performance?
I also applied below view criteria, but still its not performant.
// ViewCriteria vc = vo.createViewCriteria();
// //.getViewCriteriaManager().getViewCriteria("SelectedMerchantCriteria");
// ViewCriteriaRow vcr = vc.createViewCriteriaRow();
// vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_CACHE | ViewCriteria.CRITERIA_MODE_QUERY);//MerchantName1
// //vcr.setAttribute("MerchantName1", "1017 CAFE");
// vcr.setAttribute("SelectToMap", "true");
// vc.addRow(vcr);
// vo.applyViewCriteria(vc);
// vo.executeQuery();

Hi
Please check this post [http://adfwithejb.blogspot.in/2012/08/hi-i-came-across-one-common-use-case.html].
It has clear explanation of how to provide a checkbox for selection of rows. You can also go through my comments at the end of the post. That should solve your problem of iterating through the entire VO.

How to maintain selected row in adf table displayed after refresh

Hi,
I am using jdev 11g
I my jsf page I have a table with multiple rows.
When i scroll and click on one of the rows its selected but if the page is refreshed the row is always selected but not displayed.
I need to be able to maintain the selected row after the refresh of the page, so my table will look like its already scrolled to the selected row..
I tried to use the attribute displayRow="selected" but it won't do the trick.
Any hints

Kindly answer the following if you may.
Is there a way to refresh the table after the selectListner is fired.

How to add a row in internal table at first row

Hi All,
              I need to add a row in an internal table which already has some contents.I want to add this row in the first row.
Please advice.
Thanks in advance.

You mean - you want to replace the 1st record in the internal table. or you want to sum the new values to the existed record.
If you want to replace - then you can use as
read table itab index 1.
if sy-subrc = 0.
    itab-f1 = 'new value'.
    modify itab index sy-tabix.
endif.

How to set selected row on startup of an alv tree build with cl_salv_tree

HI,
I have a cl_salv_tree and want the tree structure to open a specific node when starting the report. My coding is something like that:
DATA: lr_selections       TYPE REF TO cl_salv_selections_tree,
        lr_nodes            TYPE REF TO cl_salv_nodes,
        lr_node             TYPE REF TO cl_salv_node,
        lv_node_index(12)   TYPE c,
        lt_nodes            TYPE salv_t_nodes,
        ls_nodes            TYPE salv_s_nodes,
        lr_item             TYPE REF TO cl_salv_item.
lr_selections = lr_tree->get_selections( ).
lt_nodes = lr_selections->get_selected_nodes( ).
lr_item = lr_selections->get_selected_item( ).
IF lr_item IS NOT BOUND.
lr_nodes = lr_tree->get_nodes( ).
lr_node = lr_nodes->get_node( lv_node_index ). "lv_node_index is the index of the node i want to be open on startup
ls_nodes-key = lv_node_index.
ls_nodes-node = lr_node.
APPEND ls_nodes TO lt_nodes.
lr_selections->set_selected_nodes( lt_nodes ).
ELSE.
ls_nodes-node = lr_item->get_node( ).
ls_nodes-key = ls_nodes-node->get_key( ).
APPEND ls_nodes TO lt_nodes.
lr_selections->set_selected_nodes( lt_nodes ).
ENDIF.
This coding is also used, when the report is running and someone clicks an a row. So thats why I check if a item is marked
or the total row.
But the tree always starts without opening the node.
Do I use the right methods or am I totally wrong ????
Thx for your help in advance
dinodini
Edited by: dinodini on Nov 16, 2010 6:51 PM

What you are looking for is the similar functionality which could be achieved by the method EXPAND_NODE of the ALV Tree created using CL_GUI_ALV_TREE. In SALV Tree, you can use the method EXPAND of the class CL_SALV_NODE to show all the subnodes of that node, not by using the SELECTION.
Once you add the Node using the method ADD_NODE, you should call the method EXPAND to expand that subtree.
            lr_nodes = lr_tree->get_nodes( ).
            lr_node = lr_nodes->ADD_NODE( ... )
            lr_node->EXPAND( COMPLETE_SUBTREE = 'X' ).
