Editable field with F4 help in alv tree output using cl_gui_alv_tree

HI
i need Editable field with F4 help in alv tree output using cl_gui_alv_tree
Regards
Naresh

Hi Naresh,
Pass the field catalog with the additional parameter (ls_fcat-edit = 'X'.).
for F4 help if the data element have the search help it automatically will come. other wise include the additional parameter in the field catalog (ls_fcat-F4AVAILABL = 'X')
Reward if found helpful.

Alv field with f4 help without using class

Hi,
Can any one give me a program of "Alv field with f4 help without using class".
Thanking you in advance.

hi
Linking F4 Help to Fields
For the last section, we will deal with linking F4 help to fields. It is easy. As usual, define, implement and register the event onf4 at proper places in your code. For F4 help, you must register the fields whose F4 request will trigger the onf4 event. For this you must prepare a table of type LVC_T_F4 and register this table using the method register_f4_for_fields. While preparing table you must include a line for each field which will trigger F4 event. For each field in the structure;
􀂾 Pass the fieldname to FIELDNAME
􀂾 Set REGISTER to make the field registered,
􀂾 Set GETBEFORE to provide field content transport before F4 in editable mode
􀂾 Set CHNGEAFTER to make the data changed after F4 in editable mode.
DATA: lt_f4 TYPE lvc_t_f4 WITH HEADER LINE .
lt_f4-fieldname = 'PRICE'.
lt_f4-register = 'X' .
lt_f4-getbefore = 'X' .
APPEND lt_f4 .
CALL METHOD gr_alvgrid->register_f4_for_fields
EXPORTING
it_f4 = lt_f4[] .
Preparing table for the fields to be registered to trigger F4 event
METHOD handle_on_f4 .
PERFORM f4_help USING e_fieldname es_row_no .
er_event_data->m_event_handled = 'X' .
ENDMETHOD .
A sample onf4 method implementation
Again, we set the attribute er_event_data->m_event_handled to prevent further processing of standard F4 help.

Error while adding a custom field with Input help via AET

Hi All,
I need to add two custom field under Service orders at Item level in component BT140I_SRVP.
One field is required to have the input search help f4 and autopopulates the second field
I am able to add one field(not requiring help) successfully through AET .
I have created one Zsearch_help in se11 and its successfully running and Autopopulating seocnd field while I am testing it
While adding second field through AET,I need to enter following details as -
field label,search relevant ,serach help etc.
When I type the name of my 'Zsearch_help' against field search help it gives me following error
'Search help is not compatible'.
Secondly,not getting getter and setter methods for the attrributes in BTAdminI.
Last,please tell me if i create zhelp and activate it,would it automatically appear in the list on AETwhile assiging it to input field?
Please help me out.Kindly be detailed as I am new to SAP CRM.
Thanks,
Shivani

Double click in ALV tree output????

Hi all,
I am able to display output in tree format. But I want to add the double click functionality to some of the fields in output. Means if I double click on some value in output tree, it should call some transaction. Please help me with this issue of double clicking.
Please tell how to handle events in this report tree display.
For the following code its displaying output in tree format and in right way. But i need to add double click functionality to this.
So provide me some sample program for this one....
* create hierarchy
CALL METHOD tree1->set_table_for_first_display
 EXPORTING
 it_list_commentary = lt_list_commentary
 i_background_id = 'ALV_BACKGROUND'
 i_save = 'A'
 is_variant = ls_variant
 CHANGING
 it_sort = gt_sort[]
 it_outtab = itab_outtab
 it_fieldcatalog = t_fieldcat. "gt_fieldcatalog.
* expand first level
CALL METHOD tree1->expand_tree
 EXPORTING
 i_level = 1.
* optimize column-width
CALL METHOD tree1->column_optimize
 EXPORTING
 i_start_column = tree1->c_hierarchy_column_name
 i_end_column = tree1->c_hierarchy_column_name.
In grid ALV we can have double cilck functionality using code:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
 EXPORTING
 i_callback_program = w_repid
 i_callback_pf_status_set = 'PF_STATUS'
 i_callback_user_command = 'USER_COMMAND'
 is_layout = ls_layout
 it_fieldcat = gt_fc[]
Here we can write subroutine for USER_COMMAND and handle the double click evenet. But tell me how to provide this in tree ALV.

Sachin

Add/Edit/Delete Tree Nodes using CL_GUI_ALV_TREE

Hi All,
I am looking for an example of program with CL_GUI_ALV_TREE that have a functionality of add a tree node, edit a tree node, and delete a tree node.
I have already looked the BCALV_TREE* demo program but could not able to find a program to add/edit/delete node tree elements.
Any info on this.
Thanks
aRs

Hello aRs
Here is a sample report showing how to delete nodes in an ALV tree. The report was copied from BCALV_TREE_01. Search for added code:
*$ADDED: begin
*$ADDED: end[/code]
When you display the tree expand the first folder completely. When entering 'DELETE' into the command field directly the first flight date node will be deleted.
REPORT ZUS_SDN_BCALV_TREE_01_DELNODE.
based on: REPORT bcalv_tree_01.
Purpose:
~~~~~~~~
This report shows the essential steps to build up a hierarchy
using an ALV Tree Control (class CL_GUI_ALV_TREE).
Note that it is not possible to build up this hierarchy
using a simple ALV Tree Control (class CL_GUI_ALV_TREE_SIMPLE).
To check program behavior
~~~~~~~~~~~~~~~~~~~~~~~~~
Start this report. The hierarchy tree consists of nodes for each
month on top level (this level can not be build by a simple ALV Tree
because there is no field for months in our output table SFLIGHT.
Thus, you can not define this hierarchy by sorting).
Nor initial calculations neither a special layout has been applied
(the lines on the right do not show anything).
Note also that this example does not build up and change the
fieldcatalog of the output table. For this reason, all fields
of the output table are shown in the columns although the fields
CARRID and FLDATE are already placed in the tree on the left.
(Of course, this is not a good style. See BCALV_TREE_02 on how to
hide columns).
Essential steps (Search for '§')
~~~~~~~~~~~~~~~
1.Usual steps when using control technology.
 1a. Define reference variables.
 1b. Create ALV Tree Control and corresponding container.
2.Create Hierarchy-header
3.Create empty Tree Control
4.Create hierarchy (nodes and leaves)
 4a. Select data
 4b. Sort output table according to your conceived hierarchy
 4c. Add data to tree
5.Send data to frontend.
6.Call dispatch to process toolbar functions

§2. Create Hierarchy-header
The simple ALV Tree uses the text of the fields which were used
for sorting to define this header. When you use
the 'normal' ALV Tree the hierarchy is build up freely
by the programmer this is not possible, so he has to define it
himself.

IMPORTANT: Table 'gt_sflight' must be empty. Do not change this table
(even after this method call). You can change data of your table
by calling methods of CL_GUI_ALV_TREE.
Furthermore, the output table 'gt_outtab' must be global and can
only be used for one ALV Tree Control.

Sort Icon/option in ALV tree repot using classes and methods

Hi all,
I have done an alv tree report using the class cl_gui_alv_tree
and i need to let users re-sort the report by using a sort icon(as visible in a normal alv report).Is there any possibility to create an icon and set the functionality such that the entire tree structure gets resorted depending upon the sort criteria?Please give me an example of doing so if there is an option.

if u want without classes then i can give an example of Sort Icon/option.

Problem in displaying Alv grid output using oops........

hi,
i have two problems in displaying ALV grid output Using Oops.
1) How to modify the fieldcatalog after we getting a field catalog using general FM.
2) initialy it is displaying 13 fields but there are 63 fields .
eventhough we chage the layout to 63 fields it is displaying only 13 fields , these 13 fields may be different based on our selection but count of displayed fileds are same . how can display 63 fields at a time .

Hi,
You can chnage using below code:
loop at gt_fieldcat.
if <gt_fieldcat-field_name> = 'FIELDNAME'.
endif.
modify gt_fieldcat.
clear gt_fieldcat.
endloop.
Make sure that all the field should not have no_out = 'X' and tech = 'X'.
Thanks,
Sriram Ponna.

Editable Field in ALV TREE Display Using OOPs

Hi,
I am trying to make a field editable on the ALV Tree display. I could create an editable check box. But could not make a field Editable. I have made EDIT = 'X' in the fieldcatalog for the particular field. but it is not working.

You do this with the following code example
DATA: ls_layout TYPE lvc_s_layi.
CLEAR ls_layout.
ls_layout-class     = cl_item_tree_control=>item_class_text.
ls_layout-editable   = 'X'.
ls_layout-fieldname = your fieldname.
APPEND ls_layout TO lt_layout.
add PO header to tree
      CALL METHOD tree->add_node

          i_relat_node_key = space
          i_relationship   = cl_gui_column_tree=>relat_last_child
          i_node_text      = l_node_text
          is_outtab_line   = ls_po_item
          is_node_layout   = wa_layout_node
          it_item_layout   = lt_layout

Getting error while adding a custom field (with input help) through AET

Hi All,
I need to add two custom field under Service orders at Item level in component BT140I_SRVP.
One field is required to have the input search help f4 and autopopulates the second field
I am able to add one field(not requiring help) successfully through AET .
I have created one Zsearch_help in se11 and its successfully running while I am testing it
While adding fsecond field through AET,I need to enter following details as -
field label,search relevant ,serach help etc.
When I type the name of my 'Zsearch_help' against field search help it gives me following error
'Search help is not compatible'.
Please help me out.Kindly be detailed as I am new to SAP CRM.

Thanks for very helpful reply. After implementing the suggested SAP note, I am able to see the getter and setter methods.
So one of my problem has got solved with your kind help:)
As per your another suggestion,I have created the enhanced fields without the search help from AET in the node BTAdminI with names Plant(ZZPLANT) and Storage Location(ZZStoarge_Loc).
Now I am facing below problem:
Since Plant needs to autopopulated by Storage Location (search Help ZOFI_SHLP_STORAGE_LOC),So I need to Implement Getter setter method.
I have written below code into Get_V_ZZStorage_Loc Method:
method GET_V_ZZSTORAGE_LOC.
DATA:
    ls_map    TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping,
    lt_inmap TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab,
    lt_outmap TYPE if_bsp_wd_valuehelp_f4descr=>gtype_param_mapping_tab.
    ls_map-context_attr = 'ZZSTORAGE_LOC'.
    ls_map-f4_attr      = 'STORAGE_LOC'. (Storage_loc is the parameter defined in search help)
    APPEND ls_map TO: lt_inmap, lt_outmap.
CREATE OBJECT rv_valuehelp_descriptor TYPE cl_bsp_wd_valuehelp_f4descr
    EXPORTING
      iv_help_id        = 'ZOFI_SHLP_STORAGE_LOC1'
      iv_help_id_kind   = if_bsp_wd_valuehelp_f4descr=>help_id_kind_callback
      iv_input_mapping = lt_inmap
      iv_output_mapping = lt_outmap.
endmethod.
But its not working.Should I write some code in Get_P_XX or some other method also?
Kindly suggest .

Runtime Error in ALV Tree Output

Dear All, I am trying to create a ALV Tree using Class cl_gui_alv_tree. The Report Shows the Output with the first Node but when i try to expand it is dumping with a runtime error GETWA_NOT_ASSIGNED in class CL_ALV_TREE_BASE and method SET_ITEMS_FOR_COLUMN. The Reason being the data which was copied in the initial node display to mt_outtab is getting refreshed.
Can any one of you help me the reason for the table getting refreshed. Do i need to pass any data.
I am doing the following steps.
1. Create Container,
2. Create Tree Class object
3. Generate the Field Catalog.
4. Set table for first display " With empty internal table
5. Generate the Hierarchy
6. Call the Method Frontend Update.
Let me know if i had missed any steps in the process.
Thank you,
Regards,
Swaroop Patri

One reason for getting this error is using local defined tables for it_outtab parameter in the below code:
To get rid of the dump, define two distinct output tables globally: one is an empty table which you will pass to the below method, other one is your real output table whose size increases dependently.
CALL METHOD go_tree->set_table_for_first_display
      EXPORTING
        is_hierarchy_header = ls_hier_header

I have developed ALV report using the FM REUSE_ALV_GRID_DISPLAY.
My requirement is to have a customized search help on the output of ALV on one field.
I tried to find it on SDN but all the methods are using OO ALV.
How we can attaché customized search help in ALV developed using the FM REUSE_ALV_GRID_DISPLAY.
Kindly Help

Hii..
If you use OO then it is very easy to create a F4 help on the ALV..
try this sample code
