Help on PROCESS ON VALUE-REQUEST

Is it possible for getting values into mulitple fields based on the selection made with in a PROCESS ON VALUE-REQUEST Block.
In the F4 based on POV there are 4 fields, when the user select any one is it possible to get the other 3 into respective fields?

hi saji
Thats very much possible if you just want to populate any of the possible values in the fields.
Write a piece of code which selects the other field values apart form the one you enter in the at selection-screen output event.
for Example if the field entered is matnr for suppose then you can write a select single for other fields say plant and storage location in this event so these fields automatically gets populated once you hit the enter key as this event acts as a PBO for selection screen.
I hope I have made things clear. if any do ask me, I can answer the same.

F4 help on Process on Value-Request

Hi,
I have disgned a Table Control with 3 fields. When i press F4 on First field, it displays list of values to be selected. When we select a row, it should pull up the values into all the 3 fields in the table control.
Can you please help me in Achieving this? and I dont want to create Search help for this.
Any help will be rewared.

F4 help needed in Process on value-request

Hi,
I have two fields on screen: region and its description in a dialog program. I want region description to be populated as soon as I select F4 help for region. Description field is output only . I want to do it using a module in Process On value-request. Field p_region MODULE GET_REGION_DESCRIPTION.
Using standard F4 help I can do it. If in my table I assign search help at field level for region. For example :
Search Help: ZREGION_SHLP. Selection method: ZREGION. Fields: Region and Description.
Table name : ZREGION.
i) 1st Fields: REGION , Data Element - ZREGN, Domain: ZZREGN ( CHAR2), Value table: ZREGN. Assign Search help at field level instead of data element level.
ii) 2nd Field: REGION_DESC, Data Element - BEZEI30.
in program: DATA: p_region like zregion-region. So if I press F4 help and select one region, description field gets populated.
I don't want to use standard functionality but want to write code in POV event. If I use F4IF_INT_TABLE_VLUE_REQUEST function module, I will get all the values associated with the field region. Since I don't know which region user has selected, i can't populate description. How to get the selected value in POV for that particular field. How can I get the value selected for region and then use DYNP_VALUES_UPDATE function module to update the description field. I tried search help exit event return to return the selected value. How to pass that value in POV module as you cannot use FORM ENDFORM . inside MODULE ENDMODULE.

1st step is:
choose screen 2000 for the program using t-code se80.
at the end of the coding enter the below code:
process ON VALUE-REQUEST.
FIELD screen field name module f4_zsearchhelp.
after typing the code double click on f4_zsearch help.
it ll ask for includes, Choose as main program.
then enter the below code after choosing:
DATA : t_dynpro_value TYPE TABLE OF dynpread,
v_field_value LIKE LINE OF t_dynpro_value,
lt_fields TYPE TABLE OF dfies,
t_return_str TYPE TABLE OF ddshretval,
w_return_str TYPE ddshretval,
v_text TYPE char25.
DATA: t_ty_prov_id TYPE STANDARD TABLE OF ty_prov_id,
w_ty_prov_id TYPE ty_prov_id.
CLEAR: t_ty_prov_id], w_ty_prov_id, t_return_str[, w_return_str.
enter the select query from the description table to get the description for the particular code.
in this i had mentioned with an example that i m getting description for massg :
p9001-massg ll have the value and v_text ll have the description.

Process On Value Request with Search Help Problem

I have a screen with a field that has a custom search help attached to it. I am using Process On Value-Request which ultimately uses function module F4IF_FIELD_VALUE_REQUEST to return the selected value from the search help. The value is then moved to the screen field.
THE PROBLEM: If I enter a value in a field on the screen, then use the search help from a different field the first value I entered gets cleared. Here is a code sample. Any suggestions as to why this is happening?
NOTE: The values that get cleared are fields on the screen that I do not reference at all in user_command_2501.

Process on Value-Request

hello experts...
i have a table control that display Item information. I would like to add value-request on vendor text field based on the item.
Example: Item A have Vendor 1 and Vendor 2 maintain in Source list.
if i click the value-request for vendor only vendor1 and vendor2 will show, not all the vendor registered in SAP.
Please help on how can i achieve this
thank you

Hi,
I think you are working with Module-Pool programming....
So,In Module Pool programing goto the particularScreen Flowlogic tab where u are looping in table control.--> Goto its layout ..In layout -
>in the Right side u can enter its check table or search help.
OR
IN FLOW LOGIC use EVENT PROCESS ON VALUE REQUEST
Both the solution will work ...
just try it.

Process on value request in Dialog screen based on value of screen field

Hello Gurus,
I have a check box on a dialog screen. If the checkbox is checked, based on that I want the other field on the same dialog screen to follow logic for F4 dropdown.
Now I know if I want to write this, I have to write this in Process on value-request. But how do I get the value of the check box checked or not on the same screen in Process on value-request.
If it had been a simple selection screen I would have defined the check box as
Parameter: v_checkbox as checkbox user-command uc1.
But how do I handle above situation in dialog screen case ?
Please help.
Regards,
Jainam.
Edited by: Jainam Shah on Sep 29, 2009 6:19 PM

Hi Shah,
You have the addition for MODULE statement as ON INPUT.
Eg : FIELD <screen field> MODULE <module> ON INPUT.
You can give the check box field name in the above statement.
If you want to find as soon as the check box is checked, you can find it here.
Or else, in the addition ON REQUEST
you can see for the check box field value whether it is checked or not.
Thanks,
Prasad

Equivalent for 'process on value-request' in WDA ?

Hello again,
i have one more requirement in building a wda-gui for an existing transaction.
In the flow-logic of the SAPGUI-transaction we have an event 'process on value-request', it is triggered when a user pushes the F4-Button or clicks onto the icon belonging to the InputField.
I need to have an equivalent in WDA.
Any ideas / workarounds ? Is perhaps OVS a possible way ?
Thanks a lot !

Hi Andreas,
You can achieve this functionality by specifying the Input help mode property of the attribute to which you are binding your input field. You can choose among the various possibilities as Dictionary Search Help/Object Value Selector/User-Defined Programming. You can even just leave it as Automatic to allow the system take care of the search help to be displayed. No matter which option you use among the above quoted ones you would be able to get your search help. You need to go for OVS only when,
"Say, for example, the value help should take into account or fill multiple input fields of your view composition. However, the different input fields are related to different value nodes, which in turn refer to different ABAP Dictionary structures. ABAP Dictionary search helps are not able to fulfill this task, since the maximum scope of such a search help is the structure to which it is related. "
The OVS component offers an interface that can:
1) Receive information about which input fields should be displayed on the selection screen,
2) Receive information about the initial values of these input fields
3) Hand back the user's input into these input fields
4) Receive the result from the data retrieval in order to display the list
5) Hand back the selected data set to the consumer program
(The above has been quoted from the SAP's standard guide)

PAI process on value-request.

Hi
In PAI of one of the screens I have module that has to be triggered on value request and show table with possible entries for that screen field (lbl_printer) .
When transaction is executed the module is not called when i hit icon close to input field (lbl_printer)so I cannot get entry help. I set up break point in the module but I didn't get in to module " request printer". It looks like program do not recognize this module at all.
Please advice .

PROCESS ON VALUE-REQUEST question..

Hi, can anyone make a suggestion:
I have an input field (on screen 200) which can be prompted with F4. When this happens the PROCESS ON VALUE-REQUEST calls a module to bring up a choice window (screen 300). Once the choice is made, a selection statement in screen 300 populates the description field on screen 200. However, while screen 200 shows the new value chosen, the description field still holds the old description. This is only refreshed when the user hits ENTER. I would like the description field to be showing the correct description immediately after the choice was made in the F4 prompt. Hope this make sense.
(I notice even standard SAP programs have this too - just hit F4 on a choice field in say VD02, the description doesn't change until the next ENTER or button click).

Hi,
Providing Input Help (F4 Help)
Use
Users of an SAP System can use the F4 key to obtain information about the possible input values for a certain field on the screen.
Information about the possible values for a field should also be available to those users who are working with the data in the SAP System from an external program, via BAPI calls. For example, the user of a Visual Basic program, which incorporates a BAPI to display or modify data in an SAP System, should have transparent access to the functions of the F4 input help.
Features
In order to provide input help, a calling program can use the BAPI HelpValues.GetList(). This method is based on the RFC-enabled function module BAPI_HELPVALUES_GET, which obtains the possible input values for a field that is passed in a BAPI call. For detailed information about the structure and use of the HelpValues.GetList() BAPI, see the documentation on the function module BAPI_HELPVALUES_GET, which implements the Helpvalues.GetList method.
To determine the possible input values for a field in the check table, the BAPI HelpValues.GetList() uses the elementary search help or the domain fixed values linked to the field in the ABAP Dictionary.
For this reason, you have to create or specify relevant check tables, elementary search helps (matchcodes) or domain fixed values. Only then can the calling program access the relevant input values for your BAPI fields using the BAPI HelpValues.GetList().
As of Release 4.5A, you have to specify a foreign key, if a check table has been defined in the domain. Otherwise F4 input help cannot be displayed.
Authorization Check
In some cases you will only want to allow only those persons with a specific user profile to access information in F4 input help. To do this you can carry out authorization checks within the BAPI using table BAPIF4T.
Table BAPIF4T is provided for this purpose. This table comprises the following fields, which you have to fill with the values for your BAPI.
OBJTYPE (object type)
The technical name of the SAP business object type, for example, BUS1065.
METHOD (verb)
The name of a BAPI for the business object type named above, for example, GetList.
DTEL (data element)
The name of a data element for which a possible entry is specified. For example, an elementary input help could be specified for the data element PERNR_D and be protected from unauthorized access.
FNAM (name of the function module)
The name of the function module that you have to create and that checks authorizations for the data element. This function module must have the following predefined interface:
""Local interface:
*" IMPORTING
*" VALUE(OBJTYPE) LIKE BAPIF4F-OBJTYPE
*" VALUE(METHOD) LIKE BAPIF4F-METHOD
*" VALUE(DTEL) LIKE BAPIF4F-DTEL
*" VALUE(SHLPNAME) LIKE BAPIF4F-SHLPNAME
*" VALUE(TABNAME) LIKE BAPIF4F-TABNAME
*" EXPORTING
*" VALUE(RETURN) LIKE BAPIF4F-RETURN
As the template for your function module you can use the function module BF_BAPI_F4_AUTHORITY which provides exactly this interface. Copy this function module and follow the documentation provided with it.
The additional parameter SHLPNAME contained in the function module interface provides the name of the active input help for the table or for the data element. The parameter TABNAME contains the name of the value table.
The return code of the parameter RETURN is:
'X' if the user of the BAPI is not authorized to call up the valid input values for a field.
' ' (no value), if the user of the BAPI is authorized to display the input values for a field.
During runtime the function module is called dynamically by the BAPI HelpValues.GetList().
An authorization check can be carried out at business object type, method or data element level:
To check authorizations at this level
... ......the following fields in table BAPIF4T must be filled.
Business object type
OBJTYPE, FNAM
BAPI
OBJTYPE, METHOD, FNAM
Data Element
OBJTYPE, METHOD, DTEL, FNAM

HI
well I am not sure about this it works or not but we have various function modules which we can call in other function modules to provide F4 help i mean to say that call Function module inside a Function Module
F4IF_INT_TABLE_VALUE_REQUEST
F4IF_FIELD_VALUE_REQUEST.
Try out these Fm calling ..
I hope it helps you am not sure

Process on value request for table control

I have 10 rows in a table control,when a F4 for
a particular column in a row is called,process on value request is called here i call a customized F4 based on the structure mapped to the row,but unfortunaletly unlike the screen the mapped structure is not populated,so is
there a way of getting the structure mapped to the row.

Hi Kaushik
As I guess solution would be reading the row into the structure which the F4 screen uses.
e.g.
GET CURSOR LINE lv_linno .
lv_linno = lv_linno + <table_control_name>-top_line - 1 .
READ TABLE <itab> INTO <screen_structure> INDEX lv_linno.
If this is not the case, then posting your POV coding will be better to analyze your code.
