F4-Help without using a table search help

Hi,
We´re using CRM 2007 and I have created several F4-Helps for different fields on the webui.
There it was always necessary to use an existing table search help in the GET_V-method:
CREATE OBJECT rv_valuehelp_descriptor
    TYPE
      cl_bsp_wd_valuehelp_f4descr
    EXPORTING
      iv_help_id                  = lv_help_id   "search help name
      iv_help_id_kind             = if_bsp_wd_valuehelp_f4descr=>help_id_kind_name
      iv_input_mapping            = lt_inmap
      iv_output_mapping           = lt_outmap
      iv_trigger_submit           = abap_true.
But how can I create a f4-help without an existing search help. I have an internal table that I want to be shown like an f4-help (not as dropdown -> a dropdown-field wouldn´t be a problem).
Structure of the internal table: COML_PROD_CAT_REL_F4
Thanx for help.
Greetings,
Sven

Hi Sven,
you already pasted the correct call for creating a value help. Now what you have to alter is the variable lv_help_id to reflect a F4-Valuehelp class.
      CREATE OBJECT rv_valuehelp_descriptor TYPE cl_bsp_wd_valuehelp_f4descr
        EXPORTING
          iv_help_id        = '(CL_CRM_UIU_BP_IDTYPE_2_F4)' "#EC NOTEXT
          iv_help_id_kind   = if_bsp_wd_valuehelp_f4descr=>help_id_kind_comp
          iv_input_mapping = lt_inmap
          iv_output_mapping = lt_outmap.
As you can see CL_CRM_UIU_BP_IDTYPE_2_F4 is a normal ABAP class implementing interface IF_BSP_WD_CUSTOM_F4_CALLBACK. Please take a look at it.
It should not be very hard to implement the single method
cheers Carsten

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
<b>Linking F4 Help to Fields</b>
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.

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen

Adding elementry search help to SAP standard Collective Search help

Hi,
I had copied standard elementary search help to MAT0M to ZZ_MAT0M and added some more fields and activated to it.
it got activated sucessfully.
Now i have to attached the ZZ_MAT0M elementry search help to standard collective search help MAT1_A.
How can i do that?
can i add it directly to MAT1_A (sell --->search help <MAT1_A> changes --> in included search helpss tab using + (insert icon) )
Thanks & regards

I solved my problem :
I had copied standard elementary search help to MAT0M to ZZ_MAT0M and added some more fields and copied Database View M_MAT1M to ZZ_M_MAT1M and addedd same fields and activated both.
both got activated sucessfully.
Now i have to attached the ZZ_MAT0M elementry search help to standard collective search help MAT1_A and this Z-search help shd appear on the first tab.
so I just went to collective search help MAT1_A in change mode --> click on "+" icon addedd my ZZ__ search help, save and activated it.
If you dont really care in which tab your search help shd appear, then the best option is to use Append Search help.
Note : if you are directly adding your search help in collective standard search help, then its better to remove hotkey form your custom elementry search help, as, if not remove will lead to warnings or make sure that you have unique hotkey in that collective search help.

Table Search Help to Remove Duplicate Entry

Hi All Tha ABAP GURUS,
I have created 2 tables say A with fields main description and sub decription and another table B in which there are these 2 fields with other fields. I want to display search help for Table B for fields main description and sub decription separately and I have done the same by creating Elementary Search Help (ZDS and ZDM resp.) . For sub description it is working fine and for main description it is displaying value but duplicate. How to remove these duplicate values.
For Eg Values are
Main Desc   Sub Desc
1                   A
1                   B
1                   C
2                   D
2                   E
In my case it is showing
1
1
1
2
2
but I want
1
2
I want to achieve this without creating any ZProg. Can I use search help exit.Kindly guide me in this matter how to use it.
Thanks & Regards,
Bharti Jain

Yes you can delete duplicates in a search help exit, but not without "without creating any ZProg" as you will create a Function Module (and Group)
Duplicate the sample FM F4IF_SHLP_EXIT_EXAMPLE in a customer function group, and delete duplicate records of RECORD_TAB in the step 'DISP' (executed before display).
You could also perform the select yourself adding a DISTINCT option to the statement in the 'SELECT' step but this will take more time to develop, as you must read the other parameters to use selections provided by user or program.

Have you tried syncing once and then try transferring purchase again? Syncing should trnafer them during the sync process.
Also make sure that you don't have content that you bought with another Apple ID that needs to be transfered as well.

Creating context-sensitive HTML Help without using Map #s

I am uisng RH 8 and am producing a compiled HTML Help file.
I am wondering if there is another way to call a topic from our application without using the MAP numbers in RH.
The developer would like to use the MAP ID (string) instead.
Is there a way to do this?
Please let me know.
Thanks.

Your points are valid but there are also situations when urls are an excellent method.
For some projects our developers name fields and we have a method of identifying the name applied. We use that as our filename. By that means they know what the help file will be and can create the call before the topic exists and we don't have to maintain map ids for those projects. If we should fail to create the topic, the call has the logic to go to a higher level.
I wouldn't advise using map ids or urls, I would say understand how both work, their pros and cons, and then decide what works for the project.

Conditional Help without using build tags?

I am not a real technical person, so if I mess up on my
explanation - Sorry!. We have a one software package that can be
used 2 different ways depending on a system configuration. I
suggested using conditional build tags in order to have the correct
help files populate for the 2 different configurations. Howver,
they do not want 2 different help files. They want one help file,
but want it to pull different help topics depending on they system
configuration - kind of dynamically. So, for software 1a, only pull
10 topics, and software 1b, pull those 10 topics, plus an
additional 2...but all out of the same help file. Is that even
possible?

Welcome to the community.
Which output are you producing? If CHM, someone else will
have to address that. But for WebHelp, the system developers are
going to have to do some work here either way. For the scenario
where you have only one set of help files, you could put the 10 in
one subfolder within the help folder and the other 2 in a separate
subfolder. The developers (or web admin) could restrict permission
to the subfolder containing the 2 files based on the user's
configuration.
The problem with not using conditional tags is that if you
want those 2 topics in your TOC or index, they'll show up whether
the user has rights to see them or not. You'd have to be careful
not to link between the 10 files and the other 2; otherwise, the
user who has rights to just the 10 will get permission errors if
trying to follow a link to the 2. And I imagine that results for
the 2 will show up in search results no matter who is doing the
searching.
If you've got only 12 topics in your project, the cost
doesn't seem very high to use conditional tags and have two sets of
help output, but that's just my opinion.
Hope this helps,
Ben

Search Help - Restricting entries in standard search helps

Hi, is there any way to restrict entries in an SAP supplied search help? The search help in question is 'SSH_T007A', this search help also has a user exit 'F4_TAXCODE_USER_EXIT'. I'm not sure if the user exit is of any use or how to use it. Ideally what I need to do is to restrict the list of applicable tax codes to only those that we want our users to select. Does anyone have an idea of how to do this with a minimum of customization?
Thanks in advance,
Kevin May

Hi Seshatal,
     Thanks for the input, but this field does NOT have any ON VALUE REQUEST event associated with it ....
   as soon as F4 is hit, it goes to Function help_start ,so I don't think we can make any changes here as it is standard .
   I think including a standard search help will help....how to achieve this ?
Thanks,

F4 help in selection fields of search help

Hi all,
I've created a elementary search help for sold to party and appended it to collective search help.
Now my problem is i need F4 help in one of the selection fields of search help.
How can i get it.
I m using selection method where ive created a view which fetches all data..
Thanks in advance
Palak

Hi,
1)Double click on the dataelement of your field on which you want f4 help then in the first tab itself you will find two option one for attaching the search help you have created(Elementry/ Collective) and second option is the parameter ID.
You have to look for the first option to attach the search help.
2) You can create f4 help for your Parameter or Selection screen by using the event.
AT SELECTION-SCREEN ON VALUE-REQUEST for PARA/Selection screen.
Further you can use the FM mentioned above F4_INT.....
Hope it is clear now.
