Making cells of ALV/ Table readonly

Hi,
We have some requirement in project where we have to make cells of ALV/ Table as readonly dynamically depending on the data.
As per our understanding, we can define readonly property at column level. Is it possible to do such dynamic cell level operation in ALV / Table.
If someone has some demo application for the same, please help us out in this issue.
Best Regards,
Ruchi

Hi Ruchi.
This can be done by using cell variants. If you serach for ALV and cell variant(s) you will find some threads regarding this topic which might help you.
Cheers,
Sascha

How to set two different UIE in one cell in ALV table

Hi all,
I have a hierachy ALV table. For some reason I want to have two UI elements in one column. For example, the text and a menu next to the text. Is it possiable to do that?
best regards,
Wenwen

Hi,
thank you for your answer. Yes, now I also find the class CL_SALV_WD_MULTI_CELL_EDITOR which could be used to set different UIE in one cell. But it is quite limited, just the following UIE could be used
- LinkToAction
- LinkToURL
- FileDownload
- Button
- ToggleButton

Cell Selection & ALV Table (SALV_WD_TABLE)

Hi Experts,
is it possible to select more than one cell (not row!) in an ALV Table?
I changed the cell editor to cl_salv_wd_uie_input_field and set the whole table editable.
Now I am able to select one cell, but what about multiple selections? In the Java world I found this one: TableSingleMarkableCell
Sounds good - what about ABAP?
And if there is no way with the ALV Table, how I might get the functionality with other components?
Thanks for your help, have a great week!
Hendrik

Hi Thomas,
I tried to integrate the cell variant TableSingleMarkableCell. But I think the ALV table does not support this cell variant, or am I wrong? The runtime class is .CL_WD_TABLE_SNGL_MARK_CELL
(see http://help.sap.com/saphelp_nw70/helpdata/EN/a5/b8fa41c915da6fe10000000a1550b0/frameset.htm)
I will try to explain:
When you want to use a cell variant, it is necessary to "add" it to a column. Therefore you can use the public method "ADD_CELL_VARIANT" of the class "CL_SALV_WD_COLUMN".
This method has got a "value" import parameter which is a referencing the class "CL_SALV_WD_CV".
The thing is that the only sub class of "CL_SALV_WD_CV" is "CL_SALV_WD_CV_STANDARD" and this means that the TableSingleMarkableCell is not supported.
Or did I made a mistake? This is my last chance to use a cell selection with the alv component.
Thanks & Regards,
Hendrik

Making cell non editabale (of dynamic table) in alv

Hi,
I am working on a editable alv with a dynamic table <itab> .This table gets populated during runtime.Now I want to make few cell of this table not editabale (only few cell not the full columns) I knwo that the procedure is to
declare my outtab like
TYPES: BEGIN OF gs_outtab.
TYPES: celltab TYPE lvc_t_styl.        "field to switch editability
        INCLUDE TYPE /npu/edmt_aa_eac.
TYPES: END OF gs_outtab.
and in the celltab i pass the information of cells which will be non editable...But the problem is as my outtab is a dynamic table I cannot INCLUDE IT IN ANOTHER types.
Please help me how to do it???? Or is there any other way of doing it???

Hi Priya
Add the field of type lvc_t_styl while creating the field catalog.
Now
DATA lo_table TYPE REF TO data.
cl_alv_table_create=>create_dynamic_table(
    EXPORTING
      it_fieldcatalog = lt_fieldcat "the field catalog table
    IMPORTING
      ep_table = lo_table ). "the reference to the table gt_outtab with the style tab
FIELD-SYMBOLS <tab> TYPE ANY TABLE.
ASSIGN lo_table->* TO <tab> .
Now you can fill your <tab>.

How to create a context menu in ALV table cell editor(Webdynpro abap )

Hello Experts,
I am having a problem in creating a context menu in a table cell editor in the ALV table output.I have assigned a 'lta' as the cell editor.But befor assigning the lta as cell editor I have assigned the menu to the lta.But when the view is rendered I can see the lta with the actioned assigned to it.But I cannot see the context menu.
The code snippet below:
"Create menu for each coloumn
create OBJECT lo_menu_actions type CL_SALV_WD_VE_MENU EXPORTING
      id = 'MITM_ACTIONS'.
lo_menu_actions->set_visible( value = abap_true ).
lo_menu_actions->set_visible_fieldname( value = 'ACTIONS' ).
"ADd menu items
CREATE OBJECT lo_menu_item_create type CL_SALV_WD_VE_MENU
exporting
    id = 'MITM_CREATE_EXPRESSION'.
lo_menu_item_create->set_visible( value = abap_true ).
lo_menu_item_create->set_visible_fieldname( value = 'Create' ).
"Add item 1
lo_menu_actions->ADD_ITEM( VALUE = lo_menu_item_create ).
" Set the cell editor for each column cell(link to an action)
LOOP AT lt_node_dec_tab_cols INTO ls_node_dec_tab_cols .
    lv_column_name = ls_node_dec_tab_cols-object_name.

   "Create 'lta' Ui item
    CREATE OBJECT lo_lta TYPE cl_salv_wd_uie_link_to_action.
    lo_lta->set_menu( value = lo_menu_actions ).
    lo_lta->set_text_fieldname( lv_column_name ).
    lr_column->set_cell_editor( lo_lta ).
    IF ls_node_dec_tab_cols-is_result EQ abap_true.
      lr_column->set_cell_design( value =
                  cl_wd_table_column=>e_cell_design-key_medium ).
    ENDIF.
ENDLOOP.

Hi Prakash,
I have not come across this requirement till now to have context menu in a cell editor of alv.
Unfortunately the implementation of method SET_MENU of alv ui elements ( ex: cl_salv_wd_uie_text_view ) is not updating alv configurable table, instead it just stores in a global attribute as string. Hence has no effect on context menu.
If your user is very particular about this requirement of having context menu in cell editor, you can go for a normal table. Because, normal table's cell editor has the property to set the menuID as we do it for other ui elements.

ALV Table - Different Search Help depending on Cell

Hey you experts,
For my current project I'm working on an editable ALV Table. The table has three columns and shall contain:
1) The name
2) The Old value
3) The New Value
of an item.
The name of the item is known (e.g. Product Category, Accounting Type and so on).
The main problem: I have/want to offer search-help to the user in the second and third column depending on the content of the first cell ==> The search help can of course differ in several rows. Example:
NAME         OLD-VALUE         NEW-VALUE
P.Category     Computer           Notebook
Acc.Type.       A                            B
The Computer field, shall have a search-help for a differnt data-type (DDIC help) than the A/B types.
Is this possible? There should be a kind of "On-Open-F4-Help" event in which i can adjust the F4 help, which shall be used depending on the currently selected cell.
Thanks for any help,
greetings,
Timo Stark

Hey Sam,
Yes I was able to achieve it. Create a collective search help, which includes all relevant data-elements.
Create a search hel exit.
Use the following code:
IF CALLCONTROL-STEP <> 'SELONE' AND
     CALLCONTROL-STEP <> 'SELECT' AND
     " AND SO ON
     CALLCONTROL-STEP <> 'DISP'.
     EXIT.
ENDIF.
* STEP SELONE (Select one of the elementary searchhelps)
* This step is only called for collective searchhelps. It may be used
* to reduce the amount of elementary searchhelps given in SHLP_TAB.
* The compound searchhelp is given in SHLP.
* If you do not change CALLCONTROL-STEP, the next step is the
* dialog, to select one of the elementary searchhelps.
* If you want to skip this dialog, you have to return the selected
* elementary searchhelp in SHLP and to change CALLCONTROL-STEP to
* either to 'PRESEL' or to 'SELECT'.
DATA: lv_line LIKE LINE OF SHLP_TAB,
        lv_line_tmp LIKE LINE OF SHLP_TAB.
DATA lv_current_context_element TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA lv_parent_data TYPE /SIE/SRM_FYC_CHANGE.

      WHEN OTHERS.
        lv_line-SHLPNAME = ''.
        callcontrol-step = 'EXIT'.

* Normaly only SHLP-SELOPT should be changed in this step.

ABAP WD: TreeByKeyTableColumn in ALV table (SALV_WD_TABLE)

Hello,
is is possible to add a TreeByKeyTableColumn object to a ALV table created
using the SALV_WD_TABLE interface?
I know that this question has already been posted several times - but the general answer ("use hierarchy columns and set_display_type( ..)") is not satisfying, since I have got the following:
The context node of cardinality 0..n which corresponds to the "column tree" to be displayed has got
- one KEY attribute
- one PARENT_KEY attribute
- one NODE_TEXT attribute
- several attributes which correspond to the table lines (respectively tree lines)
Example:
The context of cardinality 0..n has got six attributes:
KEY, PARENT_KEY, NODE_TEXT, col1 col2 col3.
During runtime, there are five "lines" in this node:
KEY    PARENT_KEY    NODE_TEXT   col1 col2 col3
1         (none)                 "node1"             a      a     a
2         1                        "node2"             b      b     b
3         2                        "node3"             c      c     c
4         1                        "node4"             d      d     d
5         (none)                 "node5"             e      e     e
The result should be in this case as if I'd have
- a table with the columns col1, col2, col3 and
- a TreeByKeyTableColumn with
     -- ROW_KEY      bound to KEY
     -- PARENT_KEY bound to PARENT_KEY
     -- containing a TextView with TEXT bound to NODE_TEXT
Result in Display:
-> node1             a   a   a                 <= Top level node
    ---> node2        b   b   b                 <= child of node with text "node1"
> node3   c   c   c                 <= child of node with text "node2"
    ---> node4        d   d   d                 <= child of node with text "node1"
-> node5            e   e   e                 <= Top level node
Can this be established with the built in hierarchy functionality of the SALV_WD_TABLE interface, too?
When playing around with the hierarchy columns functionality of SALV_WD_TABLE, I always got extra lines for the tree nodes with empty cells to the right (which I definitly don't want), and I was not able to use the parent_key<->key information already contained in the context node attributes.
But perhaps I have overlooked something?
Or is it possible to get somehow, by wild navigation through the available objects/classes/interfaces of the SALV_WD_TABLE interface, a reference to the corresponding table UI element to be able to dynamically add a TreeByKeyTableColumn with the wanted bindings?
Regards & thanks for your help

Once you have created a boolean attribute 'DAYS_READONLY' in the node bound to the DATA node of ALV, you need to set this attribute to false (for that row) if you want DAYS field to be editable when the user creates another row. In the method where you have populated the data which is being displayed make this attribute as true for those rows.
After this where you have made the ALV config settings write the following code.
DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
lr_column = lr_column_settings->get_column( 'DAYS' ).
CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'DAYS'.
lr_column->set_cell_editor( lr_input_field ).
lr_input_field->set_read_only_fieldname( value = 'DAYS_READONLY' ).
CALL METHOD lr_column_settings->delete_column
    EXPORTING
      id     = 'DAYS_READONLY'
In this code you are creating input field as a cell editor and assigning it to DAYS column. After this you are setting the readonly property of the column DAYS to the value of the column 'DAYS_READONLY'. Since this column can have different values for each row, the column DAYS will be made readonly/editable accordingly. Finally you are deleting the column DAYS_READONLY from ALV output as we do not want to display its value to the user.
For more info you can refer to thread: [ALV List in the same Column for the row CELL i need button or value;

Double click on cell in alv report

Hi all,
I want to show detail popup on cell of alv report. how to get the cell value.
plz tell me the logic for getting cell value.
thanks in advance.

Hi,
IF RS_SELFIELD-FIELDNAME = 'EBELN1'.
* Read data table, using index of row user clicked on
READ TABLE IT_EKKO INTO WA_EKKO INDEX RS_SELFIELD-TABINDEX.
Please remember the field EBELN1 should be in IT_EKKO. after the read statement you can move which ever field you want to another for further processing
like
READ TABLE IT_EKKO INTO WA_EKKO INDEX RS_SELFIELD-TABINDEX.
if sy-subrc eq 0.
move it_ekkp-( your field name) to v_field
endif.
