ALV search help

Hi all:
I have a requirements for an ALV of 2 columns (A and B).
Based on the value for row A a search help should be displayed on the column B.
P.e. If column A row 1 value is YES column B should display a search help.
If column A row 2 value is NO column B should NOT display the search help.
Does anybody know how to modify the catalog based on the information of the alv?
Many thanks,

Hi:
Thanks for the answer.
Your answer is helpfull but is not a solution because the search help from column B should be displayed based on value from column A. So the F4 event will not be triggered always.
If column A has value NO then NO search help will be available. That is the requirement. How can I "modify" dinamically if the B column cell requires or not the search help.
Any help would be appreciated.
Regards,

Problem with ALV search help Dictionary Search Help

Hello experts
I have a problem with ALV search help.
I use DDIC table ZXXX with text table ZXXX_T. I created DDIC search help form table ZXXX. In my WD application, in context on COMPONENTCONTROLLER i set on attribute: 'Input help mode' as 'Dictionary Search Help' and in 'Dictionary Search Help' I pass name of new created DDIC search help.
I create a input field from that atrribute and search help works fine (there was a value and description for value from text table). So I created ALV witch contains that attribute too.
Next I set column for this attribute in ALV as editable but on Serch help for this collumn I have only value. I DON'T HAVE TEXT DESCRIPTION FOR VALUE.
Please help me and tell me what I do wrong?
Miko

Hello,
Thank's for your help. I create DDic Search help for all fields from my ALV. Next I changed 'TYPE' for all ALV fields in COMPONENTCONTROLLER from ZXXX-Zfield to Zfield, and I changed 'Input help mode' from 'Automatic' to 'Dictionary Search Help'. Now I see Value and Description for value in Search Help in my ALV.

Search help (PREM) for personal no. is not coming in ALV grid table control

hi experts,
Search help (PREM) for personal no. is not coming in ALV grid table control.
i have assigned the srch help (prem) to my 'ZFIEXP_PROJALLOC' table for the emp_id.
but in output it is now showing the help.
ls_fcat-fieldname = 'EMPLOYEE CODE'.
ls_fcat-ref_table = 'ZFIEXP_PROJALLOC'.
ls_fcat-ref_field = 'EMP_ID'.
ls_fcat-outputlen = '10'.
ls_fcat-key = 'X'.
ls_fcat-edit = 'X'.
ls_fcat-coltext = 'EMPLOYEE CODE'.
ls_fcat-seltext = 'EMPLOYEE CODE'.
append ls_fcat to pt_fieldcat.
clear ls_fcat.
Then i tried to solve it using the PA0002 . ie.,
ls_fcat-fieldname = 'EMPLOYEE CODE'.
ls_fcat-ref_table = 'PA0002'.
ls_fcat-ref_field = 'PERNR'.
ls_fcat-outputlen = '10'.
ls_fcat-key = 'X'.
ls_fcat-edit = 'X'.
ls_fcat-coltext = 'EMPLOYEE CODE'.
ls_fcat-seltext = 'EMPLOYEE CODE'.
append ls_fcat to pt_fieldcat.
clear ls_fcat.
with this it is showing the help in employee code, but, when i click on an empl number, it is not added to my table control and allowing me to add the number by typing them.
plz help me.
thanks.

Hi
In the layout give layout-sel_mode = 'A'. and
pass 'A' to i_save exporting parameter to method set_table_for_first_display.
The same thing if you are working with function module

How to add search help for field in ALV object

Hello,
In a program, we use ALV object ( container) to create a liste like : field1, field2 .. but when display we do not have search help for this . Could you please help me how to add match code in this case for field 1 and field2, We use set_table_for_first_display
Thanks,

Hi,
when you define your field catalogue you can create data elements with search help in se11 and use them for field 1 and field 2.
But maybe it is enough to use data elements belonging to a domain with a value help and to set field F$AVAILABL in the field catalogue or to fill the name of the field CHECKTABLE.

Using Search Help with ALV and Dynamic context node

The topic subject already describes my situation.
I have to create, populate and remove context nodes at runtime, and bind them to an ALV, to let user display the data or modify the data. The nodes I create are always typed with a table name, but the table name is of course, dynamic.
This is all working: what's not working is help for entries inside the ALV; since the table has foreign keys and domains with check tables or fixed values, I expected that search helps were detected and managed by the framework.
Instead, no help search is displayed except the input help based on data-type of the one "Date" input fields.
I think I have to work on the dynamic node creation, and not on the ALV itself, since the latter only takes the node/attributes information, but i could be wrong. I tried with both the two following codings:
CALL METHOD lo_nd_info_root->add_new_child_node
    EXPORTING
      static_element_type          = vs_tabname
      name                         = 'SAMPLE_NODE_NAME'
*    is_mandatory                 = abap_false
*    is_mandatory_selection       = abap_false
     is_multiple                  = abap_true
     is_multiple_selection        = abap_false
*    is_singleton                 = abap_false
      is_initialize_lead_selection = abap_false
      is_static                    = abap_false
    RECEIVING
      child_node_info              = lo_nd_info_data .
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
      parent_info = lo_nd_info_root
      node_name = 'SAMPLE_NODE_NAME'
      structure_name = vs_tabname
      is_multiple = abap_true ).
The result is the same...is there any way to let the ALV know what search helps it has to use, and doesn't force me to manually build a VALUE_SET to be bound on the single attributes? There are many tables, with many fields, and maintaining this solution would be very costly.

I have checked with method GET_ATTRIBUTE_VALUEHELP_TYPE of interface IF_WD_CONTEXT_NODE_INFO, on an attribute which i know to have a search help (Foreign key of a check table).
The method returns 'N', that is the constant IF_WD_VALUE_HELP_HANDLER~CO_VH_TYPE_NO_HELP. So, the framework was not able to find a suitable search help.
Using method GET_ATTRIBUTE_VALUE_HELP of the same interface, on the same attribute, returns me '111', which is constant C_VALUE_HELP_MODE-AUTOMATIC.
Therefore, the WD framework knows it has to automatically detect a value help, but fails to find one.
Also, this means in my opinion that the ALV and the dynamic external mapping are not the culprits: since node creation, no help is detected for any attribute but the date. Honestly, I don't have a clue on what's happening.

Search help for date in ALV grid

I have ALV grid with field type date and search help for this:
ws_field-ref_table = 'ADCP'.
ws_field-ref_field = 'DATE_FROM'.
ws_field-inttype = 'D'
After I have clicked on this key F4 then I see a calendar and I have choosen some date, but in input grid field there aren't
choosen value. Why? Another search helps works perfect except this. Where is the problem?

ALV in Search Help

Hello ppl,
I have requirement wherein I need to provide an ALV display in a search help for a Selection Screen Field, kindly let me know if this is possible.
If yes the method in brief.
Will we need to use a exit in this case?

Nonconformist Pagal
You can achieve a out put in search help by passing all the required fields into a itab and pass the itab to the function module 'F4IF_INT_TABLE_VALUE_REQUEST'.
For instance check the following code to get the F4 help in select options for G/L Account. Here i am passing the itab IT_HKONT for the field HKONT. You define the structure and fill the itab with required fields and data. The structure of the itab will be populated in Search Help for that field.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR HKONT-LOW.
SELECT KSTAR KTEXT INTO TABLE IT_HKONT FROM CSKU WHERE SPRAS EQ 'EN'.
SORT IT_HKONT BY KSTAR.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = 'HKONT'
VALUE_ORG = 'S'
TABLES
VALUE_TAB = IT_HKONT
RETURN_TAB = IT_RETURN.
IF SY-SUBRC = 0.
READ TABLE IT_RETURN INDEX 1.
MOVE IT_RETURN-FIELDVAL TO HKONT-LOW.
ENDIF.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR HKONT-HIGH.
SELECT KSTAR KTEXT INTO TABLE IT_HKONT FROM CSKU WHERE SPRAS EQ 'EN'.
SORT IT_HKONT BY KSTAR.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
EXPORTING
RETFIELD = 'HKONT'
VALUE_ORG = 'S'

VALUE_TAB = IT_HKONT
RETURN_TAB = IT_RETURN.

Search Helps in ALV grids.

Hi,
I am working on ALV grids in custom control.
My requirement is to provide search helps in the ALV grid for few fields out of which the search help for one field should be populated dynamically.
Please help me.

hi
good
You can have almost everything you like in a search help. Nice search help examples are:
MPLAL (exit = F4_MATCHCODE_USER_EXIT) -> calls a selection report (transaction IP03)
HRBAS00OBJID (exit = RHF4_EXIT_OBJID) and include search helps
