Read webdynpro screen value before Search Help call

Hi Experts,
For a webdynpro screen I have added a custom field to the layout and mapped to a custom attribute which has a a standard search help determined from the dictionary attribute.
There are multiple input field in the layout and there is this custom input field with search help in the layout. During runtime is it possible to read the other inputfield in the layout before F4 is clicked? I want to read one of the inputfield whenever the f4 search help is called. None of the methods WDDOAFTERACTION, WDDOBEFOREACTION, WDDOMODIFYVIEW are triggered before the F4 search help call.
Please let me know if anyone has any idea.

Hi,
As suggested you have to use OVS or freely programmed value help. OVS is easy to use , check the below article for OVS Reference : [OVS in WDA|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/606288d6-04c6-2c10-b5ae-a240304c88ea?QuickLink=index&overridelayout=true] Also [Dynamic F4 in WDA|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70cee684-ccbb-2c10-3c94-91e806e5f7ac?QuickLink=index&overridelayout=true]
In the event handler method of OVS read the first input value using get attribute method and select the corresponding value.
Hope this helps u.,
Thanks & regards,
Kiran.

Need selection screen values in Search help user exit in same report

Hi Experts,
I am using Logical Data Base PNP.
Created a custom search help to validate the records for IT000 based on the selection screen dates.
Enter the DATEs for Data Selection Period and Person selection period in the selection screen.
When I for search help for PERNR field in the same report, I need the selectin screen DATE values to be in user-exit of search help.
This will help me in validating the records for specific employees within the date range of given DATE in selectin period.
As of now it's picking the employees based on the DATE selection of selection screen,

Search Help CALL SCREEN

Hi Guys,
please.. How can a Search Help call a SCREEN ?
I have a problem in a ABAP WebDynpro app, apparently because the search help is calling a SCREEN from the program SAPLSZA1.
This is the error message:
"Sending of dynpro SAPLSZA1 0201 not possible: No window system type specified"
The search help is KRED.
Any idea??
Thanks!

Hi,
it can call screen using search help exit. KRED is a collective search and for example it contains search help KREDY. This search help uses exit F4IF_SHLP_EXIT_VENDOR_FUZZY. It is just a function module.
Cheers

Selected value in search help cannot be returned

Hi experts!
When I select value in search help, selected value is not returned to the field.
I did like this.
1. I enhanced BP using EEW.
2. I created a new view and display an enhanced field via BSP workbench.
(an enhanced field is assigned to a check table)
3. I created GET_V_XX method as follows.
method GET_V_ZZBUT000000102.
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 = 'STRUCT.ZZBUT000000102'.
ls_map-f4_attr      = 'KEY'.
APPEND ls_map TO: lt_inmap, lt_outmap.
CREATE OBJECT rv_valuehelp_descriptor
    TYPE
      cl_bsp_wd_valuehelp_f4descr
    EXPORTING
      iv_help_id                  = 'CRMST_HEADER_OBJECT_BUIL-ZZBUT000000102'
      iv_help_id_kind             = if_bsp_wd_valuehelp_f4descr=>help_id_kind_comp
      iv_input_mapping            = lt_inmap
      iv_output_mapping           = lt_outmap.
endmethod.
Does anyone know what is wrong?

Hi Yohei,
You could resolve your issue by changing the value of the "ls_map-context_attr" to the attribute value seen on the F2 help on WebUI screen.
If you change the value   ls_map-context_attr to   'ZZBUT000000102' , then F4 help would work properly.
Hence the correct code would be:
method GET_V_ZZBUT000000102.
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 = 'ZZBUT000000102'.
ls_map-f4_attr      = 'KEY'.
APPEND ls_map TO: lt_inmap, lt_outmap.
CREATE OBJECT rv_valuehelp_descriptor
    TYPE
      cl_bsp_wd_valuehelp_f4descr
    EXPORTING
      iv_help_id                  = 'CRMST_HEADER_OBJECT_BUIL-ZZBUT000000102'
      iv_help_id_kind             = if_bsp_wd_valuehelp_f4descr=>help_id_kind_comp
      iv_input_mapping            = lt_inmap
      iv_output_mapping           = lt_outmap.
endmethod.

WAD template with BSP Application - how to read selection screen values

Hello,
I've created Web template with Web Application Designer (WAD).
I would like to extend that page with BSP Application...
Purpuse of this application is to read some information from tables
on BW transaction server and display them within Web page.
Question: How to read selection screen values from a Web template ?
Thanks for any help,
Pawel Borowiec

Hi,
The selection screen parameters will be on an inputField, so try and get the is of the inputfield generated by doing View source...
And once you get the inputfield Id, you can read the value in the InputField(InF) by
using the following code...!
data : if_value type ref to cl_htmlb_inputfield.
data : variable type string.
if_value ?= cl_htmlb_manager=>get_data( request = request
                                            name    = 'inputField'
                                            id      = 'InF_ID_here'
       if if_value->value is not initial.
         variable = if_value->value.
       endif.
Hope this helps.

Restricting the Value of Search help in MIRO based on vendor

Dear all,
I had a problem in resticting the values of search help for vendor in the Po reference tab. the Seach help is KRED . I had written a search help exit in it but i dont know how to restrict the vaues. I have to restict the Vendors Which starts with 1 series like 10000001,1000002 etc.
Can any one help me out where to write the code in search help exit like CALLCONTROL-STEP = 'SELONE' or 'SELECT' or 'DISP' and what logic i need to use.
Thanks & regards
sreehari p

Hi Sreehari,
Write your Select query inside IF callcontrol-step = 'DISP'.
Use below code.
*Types
TYPES: BEGIN OF l_ty_tab,
         lifnr TYPE lifnr,
         END OF l_ty_tab.
DATA: l_t_tab TYPE TABLE OF l_ty_tab,
        l_wa_tab TYPE l_ty_tab,
        l_wa_recordtab TYPE seahlpres.
*Before displaying hitlist
IF callcontrol-step = 'DISP'.
    REFRESH: record_tab[],l_t_tab[].
SELECT LIFNR FROM lfa1 INTO TABLE l_t_tab WHERE lifnr LIKE '1%'.
IF NOT l_t_tab[] IS INITIAL.
*Pass hitlist to standard table record_tab
    LOOP AT l_t_tab INTO l_wa_tab.
      l_wa_recordtab-string = l_wa_tab.
      APPEND l_wa_recordtab TO record_tab.
      clear l_wa_recordtab.
    ENDLOOP.
ENDIF.
ENDIF.

Dynamically passing the values to search help

hi
can I pass some values dynamically to search help input field.
If I select a profit centre value from a drop down in separate field it should reflect the corresponding values in
search help which is cost centre input field ( i/p fields is in a column of a UI element table).
If I add one more row also the corresponding column should bears the search help...
thanx in advance.......

Data dictionary based search helps can have multiple importing parameters within Web Dynpro. There are few rules that are documented in the online help however:
Be aware that import and export parameters for the search help are determined only within the same context node (see also Transport of Values for the Input Help), and even then only if a Dictionary structure is assigned to the node.

SAP CRM Search Help - defaulting values in search help screen

Hi All,
I am working on search help object in service order(Amount allocation ) BTAMNTALL component view name vIEW:BTAMNTALL/HdrBillplanDet and field name STRUCT.AC_ASSIGNMENT. in that block if we select account assignment type as ERP cost center it will give standard search help in Select account assignment field.
Its basically calling the standard search help CRMT_AC_ASSIGN_KOSTL_E. After pressing F4 it will display the popup Controlling area cost center and description. Basically I need to default the Controlling area in F4 help based on some logic.I am not sure where to write code for this one.
Please find the attachment where I need to default the value. any help is appreciated.
Thanks,
Sapsar.

At least can you read the document I provided carefully? the point 2.3.1.2 give you the answer.
Anyway if the document doesn't specify "defining a default value" but give you some ideas/hints, you only need to use a little your imagination. Like:
1- Use a custom search help with a constant (static)
2- Use a custom search help with a search exit to determine the data that you need from the sales org of course you need to add the orgunit as an input parameter for the search help and supress the input parameter which will be determined in the search help exit (dynamic)
3- Create a value node for the context (hidden) and put the info you need once you select the sales org in the hidden attribute/s, this hidden attributes should be mapped in the get_v method (dynamic, not sure if this will work, I never tried, but will be nice if you try and give us some feedback)

Search Help calling screen

Hi Guys,
please.. How can a Search Help implement a "CALL SCREEN" command?
I have a problem in a ABAP WebDynpro app, apparently because the search help is calling a SCREEN from the program SAPLSZA1, and I have to undo this. It shouldn't call.
This is the error message:
"Sending of dynpro SAPLSZA1 0201 not possible: No window system type specified"
The search help is KRED.
Any idea??
Thanks!

I have tried both. Same problem..
But the real problem is that I can not reproduce this in DEV. It only happens in QAS, and i can not find what is different. All the objects that I have checked so far (Search Help, Program, etc.) have no differences.

How to pass the default value to search help selection screen

Hi
I need to push a certain value as a default value based on a condition to the slection screen of search help in web UI.
Could you please let me know how can we do this?
When we try to open the 'F4' help in web ui then it should populate a certain value as a default value to the selection screen of this 'F4' help. We will get this default value based on condition.

      iv_input_mapping            = lt_inmap
      iv_output_mapping           = lt_outmap.
Here 'ZATTR1' is my search help name in SE11 and the field which is having 'F4' help is 'ATTRIBUTE'.
Now when I press 'F4' on 'ATTRIBUTE' then it will give a popup and this popup is having 3 fields..
1.'ATTRIBUTE'
2.'SERVICE_LINE'
3.Description of 'SERVICE_LINE' and hence by pressing 'F4' i should get a value in the field 'SERVICE_LINE' based on
   a condition.
However, if there is a value for ATTRIBUTE on the screen and when we press 'F4' on this then in the popup the value of
ATTRIBUTE which is there on the screen is appearing in the 'ATTRIBUTE' field and the same value is being copied to
'SERVICE_LINE' field in the popup.
Please guide me how do we populate the value to 'SERVICE_LINE' field inside the search help popup of 'ATTRIBUTE'.

Value Transport (Exporting) to multiple screen fields in Search Help

Hi all,
I have created elementary search help using exit and attached it to data element. After F4 when I get hitlist I want all the values from the selected rows to get copied to the screen fields. I.e. I want the value transport.
In the search help I am exporting those values which I want to get copied back but I am unable to get the result.
With Regards,
Chandra

Hi,
You can get this behaviour only by making the SEARCH HELP assignment at the STRUCTURE level.
You need to create or use an existing structure to create your screen fields which you want to populate using the search help. Then assign this search help directly to the structure and there do the mapping between structure fields and the search help export params.
Only by doing this you can autopopulate the values using one search help.

Sesh

Import screen field value into search help assigned to a different field

Hi,
I have created an elementary search help based on a custom DDIC table ZSH_SHHLDR. Dialog Type: Dialog depends on set of values, search help parameters:
Parameter                       Import     Export   LPos SPos SDis
FOLIO                                X                       1       1         X
CERTN                                             X         2       2
where FOLIO and CERTN are fields in my table.
There are two fields in my program defined as like FOLIO and CERTN respectively. These fields are screen fields in a custom dynpro created using Screen Painter. The search help is assigned to the CERTN field. In the screen, I want that the contents of the FOLIO field should be imported into the search help, i.e. on the screen:
FOLIO: 21353
CERTN: <F4>
When I click on F4 help for CERTN, I want that the FOLIO parameter in the search help should contain the value for FOLIO that I entered in the text box on the screen. Is there a way to do this, through an exit for instance? Help is appreciated, thanks.
Regards

Hi,
You need to use the below statement.
process on value-request.
field zcom_doa_users-zzjob_role module sub_tes_module.
Here I declared three fields in the screen fields from structure zcom_doa_users. Try to name the fields with table name-field name. So inside the module in structure zcom_doa_users you will get given value for the other fields also.
Now you can do your own processing for f4 help.
Thanks

field how can i achieve it.

Each of which is very well documented
or
trigger the drop-down in POV.
PROCESS PAI.

SELECTION-SCREEN with defined search help

Dear all,
I'd like to specify in my selection screen a variable that will contain the value to display when search help triggered.
DATA: w_lgort LIKE mard-lgort.
DATA: storage(4) TYPE c.
SELECT lgort INTO w_lgort FROM mard WHERE werks = 'p_plant'.
ENDSELECT.
storage = 'w_lgort'.

PARAMETERS : p_plant LIKE zmm13jpn-mag_emetteur DEFAULT 'C300',
p_store LIKE (storage).

My idea would be that storage contains only result of above select while using LGORT data element.
Any idea?

Modify another field value in search help exit.

While creating the Sales Order, the user does an f4 on ship to party to determine the sold to party ( search help exit ), now I have the values of both the Ship to customer and Sold to customer in the search help exit, but I can update only the ship to field of the sales order, do you know how I can modify the sold to value on the screen.
I tried setting up the parameter id 'VAG' in the search help exit with the determined value, but this value is not getting copied in the Sold to party field once the search help is executed.
The other option which is left is export to memory and import to memory in another user exit of VA01. Is there any other alternative? Also which program do I need to do the import of memory so that sold to party is displayed on the initial before saving the document ?
Ajay

Hi,
Yes..Try calling from the search help exit..
You have to pass the program name and screen number..
In the internal table parameter DYNPFIELDS..
Pass the fieldname and fieldvalue...
Thanks,
