What field are we talking about? Are you sure that the "Custom" search help is being fired and not the standard?

You can't do it, the search help populates only the field where it's called.

You should use a search help automatically created by check table.

Anyway you can do it by abap in AT SELECTION-SCREEN VALUE-REQUEST event.

Here you can run your search help by FM F4IF_FIELD_VALUE_REQUEST, get out the values and transfer them to others fields of selection-screen by FM DYNP_VALUES_UPDATE.

Hi,

Thanks for your reply. Custom search help is only triggered in the selection screen. I have set the match code object to that parameter.

What I mean is, if there is a default search help defined, chances are it is different than your custom search(otherwise what is the reason for the custom, right?) Anyway you must tell the program to use the other search instead of the default. Take the example below. Here we are using the TFDIR table for function modules. If you have a custom search help defined, you need to tell the program to use it instead of the default. In selection screens, you use the MATCHCODE OBJECT extension. In dynpros, there is a field in the screen elements tab, where you can specify the search help to use.

If this program, the standard search help is being fired for P_FUNC1, in P_FUNC2 we are telling it to fire a different one. So in your case, you can just specifiy the name of the search help after the MATCHCODE OBJECT and your search help should be fired. Make sense?



report  zrich_0001.

PARAMETERS: p_func1 type tfdir-funcname.
parameters: p_func2 type tfdir-funcname
               matchcode object SRM_FUNCNAME .

So you got it working in a selection screen. All you need to do is specify the search help in the screen elements tab in your dynpro. It will fire there as well.

In the screen, click the Element List Tab.

Click the references tab.

Enter the name of the search help for your field in the Search Help column, save, activate, run the program. Your custom search help should fire now.

Try to use this code

PARAMETERS: P1 LIKE ....

P2 LIKE ....

P3 LIKE ....

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P1.

data: dynpfields like dynpread occurs 0 with header line,

return_tab like ddshretval occurs 0 with header line.

call function 'F4IF_FIELD_VALUE_REQUEST'

exporting

tabname = SPACE

fieldname = SPACE

SEARCHHELP = <YOUR SEARCH HELP>

SHLPPARAM = ' '

dynpprog = SY-REPID

dynpnr = SY-DYNNR

dynprofield = 'P1'

tables

return_tab = return_tab

exceptions

field_not_found = 1

no_help_for_field = 2

inconsistent_help = 3

no_values_found = 4.

LOOP AT RETURN_TAB.

CASE RETURN_TAB-FIELDNAME

WHEN .... dynpfields-FIELDNAME = 'P1'.

WHEN .... dynpfields-FIELDNAME = 'P2'.

ENDCASE.

dynpfields-FIELDVALUE = RETURN_TAB-FIELDVAL.

APPEND dynpfields.

ENDLOOP.

call function 'DYNP_VALUES_UPDATE'

exporting

dyname = dynpprog

dynumb = dynpnr

tables

dynpfields = dynpfields.

You shouldn't have to do all that. Using the matchcode object extension in your PARAMETERS statement should take care of it when using selection screens.

Hi Rich

I believe he want to populate more fields than one calling search help once.

So if you use MATCHCODE OBJECT extension you can fill only the parameter where that matchcode is used.

It should be good to consider the search help is a different object: it isn't a matchcode, they have only the same functionality.

If you define a custom search help via SE11, say ZTEST, you can force the parameter to use this search help by using the MATCHCODE OBJECT extension.



parameters: p_test type c matchcode object ZTEST.

All he needs to do is add the fields that he wants to the search help and use the MATCHCODE extension. That's it.

Re: populating value using search help

RichHeilman — Thu, 02 Feb 2006 01:26:14 GMT

For example, I just create a search help called ZTEST using SE11. It is an elementary over TFDIR. I have included the following fields.

FUNCNAME

PNAME

INCLUDE

FREEDATE

APPL

MAND

FMODE

UTASK

PNAME_MAIN

Now I have a test program. Notice here that I am forcing my custom search help ZTEST.



report  zrich_0001.

parameters: p_func type tfdir-funcname matchcode OBJECT ZTEST.

When I run the program, and hit F4 on the field, I'm getting my custom search help.

I know but try to call your search ZTEST0123 and I think it won't work.

The name of matchcode can be long 5 characters, so you're lucky guy because the name of your search help is ZTEST.

You may have a valid point. but in my WAS 7.0 engine, this is working fine.

report  zrich_0001.
 
PARAMETERS: p_func1 type tfdir-funcname.
parameters: p_func2 type tfdir-funcname
               matchcode object <b>SRM_FUNCNAME</b> .

SRM_FUNCNAME is obviously greater than 5 characters. There may be a limit in eariler releases.

If it works fine you I believe you, I remembered that an error occured on release 4.6X.

I used the extension matchcode object long time ago.

Max, I don't have a 46x box in front of me to test. I actually don't use MATCHCODEs in my daily work, so I'm not sure about the 5 character name in prior releases.

Re: populating value using search help

Former Member — Thu, 02 Feb 2006 02:03:53 GMT

I'm sure, perhaps not 4.6x, but 4.0x.

I started to work using release 3.0x and this was one of first things I noted when I begun to use 4.0B

If I tried to extension control the system signaled an error.

Hello All,

I have created a webdynpro application, and would like to add a value help icon to one of the fields. On clicking the value help icon, the search functionality is launched.

Would appreciate any hints on -

1)How do I specify value help in my Webdynpro field

2)Is there any direct UI element which will create Value help field (with that button for value help against the input field)?

Please write in...

Many thanks !!!
