Parameter field in WD screen

Hello All,
how to create a parameter field (as if it were in abap selection screen ) i am using the wd component WDR_SELECT_OPTIONS in my component. i want to display a parameter field with the description taken from DDIC. iam trying to use the method ADD_PARAMETER_FIELD of the interface IF_WD_SELECT_OPTIONS.
here i could not understand how to bind this parameter field with DDIC element so that the description, (if possible F4 help)is taken from ABAP dictionary.
can someone please help.
Thanks in advance

Hi ,
What i catch from ur query is that u want to create a parameter field in the selection screen .. if so... then see the below code .
declare a variable of type data
data : lr_type ref to data .
then initial that with the type of the data element u want to use ..like WERKS_D .
create data lr_data type WERKS_D .
and call this method ...
CALL METHOD WD_THIS->M_HANDLER->ADD_PARAMETER_FIELD
    EXPORTING
      I_ID                         = 'WERKS'
       I_VALUE                      = lr_data

Mandatory parameter field in selection screen

Hi Experts,
As there are 2 options to get the input from the user. When I use select options because I need to make the field mandatory, it displays the output(blank) whenever there is no input/irrelevant input. When I use parameters, I cannot make it mandatory.
I need to display text boxes in the selection screen which should be mandatory and should only proceed when the user enters relevant data.
Please note that I have put the validation in the select options for a field like month as:
if s_month-low > '12' or s_month < '1'.
     MESSAGE 'Please enter a valid month' type 'E'.
endif.
but for a id, there is a search help. If the user do not enter the value from a search help, it displays the blank output. How to put validation on this?
Regards
Mani

Hi Mani,
You can do a validation at AT Selection Screen.Basically it will do a select single and try to fetch any line item.
A sample example as follows..
At Selection-Screen on S_DATE.
if S_date is not initial.
Perform validatedate.
Endif.
Form Validatedate.
Select single date
          from DB table
         where date in S_date.
endform.
if Sysubrc ne 0.
MESSAGE 'Please enter a valid month' type 'E'.
endif.

Adding f4-help to selection screen parameter field

Hi all.
I need to add search help to a parameter field on selection screen:
PARAMETERS:

You can give F4 help by two ways:
1. Using internal table
2. Refering db table field.
Following are e.gs:

Selection screen with Parameter - field name not coming when made mandatory

Hi Experts,
I have added a parameter in my selection screen which has other select options as well.
I used below code in wd_initi to add parameter
    create data LR_LIFNR type LIFNR.
    WD_THIS->M_HANDLER->ADD_PARAMETER_FIELD(
    I_ID         = 'LIFNR'
    I_VALUE      = LR_LIFNR
    I_OBLIGATORY = ABAP_TRUE
    I_READ_ONLY = L_READ_ONLY ).
I have a submit button in the selection screen, so when ever the value is empty in parameter for LIFNR, system throws an error *Enter selection in Field "" * but error message is unable to take the name of the parameter?
It is expected to give as Enter selection in Field "Vendor"
This throwing of error message is working fine for another select-options for PO which is also mandatory.
What could be the error?
Any clue is highly appreciated.
Regards,
Ajay

Hi,
WDDOINIT the code is:
lt_range_table = wd_this->m_handle->create_range_table(
                                                i_typename = 'ZRM_T_CV_END_DATE1' ).
wd_this->m_handle->add_selection_field(
                      i_id = 'ZRM_T_CV_END_DATE1'
                      i_description = 'Project End Date (MM.YYYY)'
                      it_result = lt_range_table
                      i_read_only = read_only ).
on submit the code is :
rt_prj_end = wd_this->m_handle->get_range_table_of_sel_field(
                                    i_id = 'ZRM_T_CV_END_DATE1' ).
ASSIGN rt_prj_end->* TO <fs_prj_end>.
1.is the data element the same in both the methods u mentioned.i,e on WDDOINIT AND ON ACTION OF SUBMIT.
please check it once.
2.2does the data element LIFNR has field label assosciated with it.(check in domain).
3.check adding description to the field shown as below.
wd_this->m_handle->add_selection_field(
                      i_id = 'ZRM_T_CV_END_DATE1'
                      i_description = 'Project End Date (MM.YYYY)'
                    it_result = lt_range_table
                      i_read_only = read_only )
Try checking these 3 cases.

How can i post the fields in the screen by selecting a record

Hi,
I have a problem in dialog programming.
I need to populate the fields in the screen by selecting a single record.
For example,
    Screen consists of 'CARRID, CONNID,FLDATE... fields.
    By pressing F4 in CARRID field it will display the contents from database table and display the records. If i select the record LH 0400 ... record then automatically the connid field should fill with the contents of the record i.e., 0400 and similarly the remaining fields.
   How can i do this in dialog programming?
   I tried with F4IF_INT_table_.. function module. There is a table parameter DYNmapping. But dont know how to use it? Can any body explain me how to use it?
   Thanks in advance..
   Suvan

Hi Vinod,
Thanks for your reply. I solved my problem. It is working with the table parameter 'DYNPFLD_MAPPING' in the function module 'F4IF_INT_TABLE_VALUE_REQUEST'.
With your logic we can't decide which record is selected. Because there can be multiple records for a single CARRID.
My question is how to post the entire record into the screen fields at a time? It is possible with the parameter I specified inthe above said function module.
With dictionary reference it will fetch the entire entries from the Check table.
Thanks again for your co-operation.

Problem in getting parameter value from selection screen in web dynpro abap

Hi,
I am facing problem in getting parameter value from selection screen.
Please find my code below:
DATA LT_PAR_ITEM TYPE IF_WD_SELECT_OPTIONS=>TT_SELECTION_SCREEN_ITEM.
FIELD-SYMBOLS:<FS_PAR_ITEM> LIKE LINE OF LT_PAR_ITEM,
                             <FS_OBJ_USAGE>    TYPE REF TO data.
WD_THIS->M_HANDLER->GET_PARAMETER_FIELDS( IMPORTING ET_FIELDS = LT_PAR_ITEM ).
LOOP AT LT_PAR_ITEM ASSIGNING <FS_PAR_ITEM>.
    CASE <FS_PAR_ITEM>-M_ID.
      WHEN `OBJ_USAGE`.
         ASSIGN <FS_PAR_ITEM>-M_VALUE->* TO <FS_OBJ_USAGE>.
[ Here, sy-subrc is 4, <FS_OBJ_USAGE> is not assigning.]
    ENDCASE.
ENDLOOP.
So, can any one solve this problem.
Thanks in advance,
Radhika

Hi Radhika,
Try using GET_RANGE_TABLE_OF_SEL_FIELD...
Please Refer below code..
   DATA: NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.
DATA: RT_CARRID TYPE REF TO DATA.
DATA: ISFLIGHT TYPE TABLE OF SFLIGHT.
DATA: WSFLIGHT TYPE SFLIGHT.
FIELD-SYMBOLS: <FS_CARRID> TYPE TABLE.
Retrieve the data from the select option
RT_CARRID = WD_THIS->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD( I_ID = 'S_CARR_ID' ).
Assign it to a field symbol
ASSIGN RT_CARRID->* TO <FS_CARRID>.
CLEAR ISFLIGHT. REFRESH ISFLIGHT.
SELECT * INTO CORRESPONDING FIELDS OF TABLE ISFLIGHT FROM SFLIGHT
                       WHERE CARRID IN <FS_CARRID>.
NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( NAME = `FLIGHTS` ).
NODE_FLIGHTS->BIND_ELEMENTS( ISFLIGHT ).

Populating description field in selection-screen

Hi Experts,
My WD report has a selection-screen with select-options and parameters built using IF_WD_SELECT_OPTIONS.
One of the select-options has a search help, but the value it returns is a guid, so I want to have a new read-only description field, populated with the description of the selected value, next to the input field for the guid.
How can I do this?
I tried adding a new read-only parameter field and populating it in WDDOMODIFYVIEW but I got a short dump when I tried to set the value, because the new field is not in the context of the component controller.
Many thanks, Ben

Hi Ben,
You will have to define the new field in the context and then programatically bind the value of the description field to this attribute.
But ideally, you can have a structure, which the two fiels (guid & description), and define a search help which is mapped to the structure, then you do not need to do any programming, the description field should get populated automatically.
Hope this helps.

Wenonah

Search help for input fields in a screen

Hi,
Pls help me
how to set search help property for the I/O fields in screen in se80?
1. do we want to add any property for search help in the property window?
2.do we want to create a MODULE PROCESS ON VALUE REQUEST ?
PLS tell me how to set search for the I/O field in se80?pls tell me the process?
i want to set the search help for more I/O fields in se80 but all the fields belongs to the same table?
can i create a single search for all these fields and use that for all the I/O fields ?
elementary search help or collective search help?
thanks & regards in advance,
vsnl.

Hi,
Input Help on the Screen
Within the Screen Painter, you can define two types of input help:
1. The FIELD statement with one of the additions VALUES or SELECT.
2. Linking a search help directly to a screen field.
If you link a search help directly to a screen field, it overrides the additions of the FIELD
statement. However, the input check [Page 581] functions of the FIELD statement remain
unaffected.
Input Help in Flow Logic
The following input help methods are obsolete and should not be used. They are still supported
for compatibility reasons.
In the screen flow logic, you can specify a value list for a screen field <f> as follows:
FIELD <f> VALUES (<val1>, <val2>,...).
The value list contains a series of single values <vali>. The NOT and BETWEEN additions for the
input check [Page 581] are not appropriate for input help.
You can also create a value list by accessing a database table as follows:
FIELD <f> SELECT *
FROM <dbtab>
WHERE <k1> = <f1> AND <k2> = <f2> AND...
In the WHERE condition, the fields of the primary key <ki> of the database table <dbtab> are
checked against the screen fields <fi>. The WHENEVER addition, used with input checks [Page
581], is not necessary for input help.
If you have used a ABAP Dictionary reference for field <f>, the selection and the hit list formatting
may be affected by any check table attached to the field.
Attaching a Search Help
Search helps from the ABAP Dictionary can be attached to a screen field [Ext.]. To do this, enter
the name of the search help in the corresponding field in the attributes of the screen field in the
Screen Painter. This assigns the first parameter of the search help to the screen field. It is only
possible to place a value from the hit list onto the screen.
Input help on a screen.
REPORT DEMO_DYNPRO_F4_HELP_DYNPRO MESSAGE-ID AT.
DATA: CARRIER(3) TYPE C,
CONNECTION(4) TYPE C.
CALL SCREEN 100.
MODULE CANCEL INPUT.
LEAVE PROGRAM.
ENDMODULE.
The next screen (statically defined) for screen 100 is itself. It has the following layout:
602 April 2001
Cancel
Airline
Flight number
Screen field with search help
Input help in the flow logic
The input fields have been adopted from the program fields CARRIER and
CONNECTION. The function code of the pushbutton is CANCEL, with function type
E. The search help DEMO_F4_DE with the search help parameter CARRID is
assigned to the screen field CARRIER. The search help uses the database table
SCARR.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
FIELD CARRIER VALUES ('AA', 'LH').
FIELD CONNECTION SELECT *
FROM SPFLI
WHERE CARRID = CARRIER
AND CONNID = CONNECTION.
When the user chooses the input help for the individual fields, the following input
help is displayed:
For the Airline field, the search help displays the names of the airlines and places the airline
code in the input field for the chosen line. If the airline code is not one of those listed in the
VALUES list of the screen flow logic, the input check triggers an error message in the PAI
event. So the search help overrides the VALUES addition for the input help, but not for the
input checks. This is therefore not an appropriate place to use the VALUE addition.
For the Flight number field, the flow logic displays the selected entries from the database
table SPFLI and places the selected line in the input field.

Automatic filling of field in sel screen where match code obj is used

Dear all.
Suppose you have a selection screen with two fields:
pa_usid and pa_name,
both fields are obligatory.
The user wants - as soon as field pa_usid is filled from the list opened through the matchcode obj,
default value gets filled in pa_name(based on the value he actually filled in
pa_usid).
How can i do that this.
Below is my code ;
parameters: pa_usid LIKE gs_leave-userid MATCHCODE OBJECT zname_lp2 OBLIGATORY DEFAULT sy-uname,,
pa_name LIKE gs_leave-name OBLIGATORY,
Thank you all very much in advance.

Validating field on selection screen

wht is the meaning of validation
how to validate a particular field on selection screen
suppose parameters:p_vkorg like vbak-vkorg.
how to validate p_vkorg.
pz give me coding

Hello pavan,
Validation means "checking whether the input which u are gining to the selection secreen is valid or not". means...
Lets take your example only...
parameters:p_vkorg like vbak-vkorg.
in selection screen you will give inout in that parameter....
users can give any input... lets suppose I'll give input as ABC... which is not in the table VBAK. No need to excute the code once we came to know that the input is not there in the table. So we will do validation like...
at selection-screen on p_vkorg.
select * from vbak where vkorg = p+vkorg. " This is the case with Parameter.
at selection-screen on p_vkorg.
Select * from vbak where vkorg = p+vkorg. " This is the case with Selct-option.
if the input that u r giving is present in the table... the above stmt will execute successfully, otherwise not.
You can make use of System variable SY-SUBRC and you can go ahead with ur coding...

Length of parameter field

Hello all,
I'm having trouble with a parameter on a selection-screen. I have a field in which the user must enter a filename/path to a workstation file. The length of the parameter field is 128 (RLGRAP-FILENAME), but on the screen, the parameters appears only in length 45 scrollable. Since our users are using loooooong directory pathes, they would like to see the complete filepath/name without scrolling. Is there any possibility to show all 128 digits of the parameter on the screen without manually editing the selection screen?
Thank you for your help, kind regards, Kathrin!

it is giving error. Please help me how to do this

Hi,
Try like below:parameters : p_file type string default '/info/ordersinfo/india/incomming/order/order.txt.' obligatory.
and then in order to grey out your other fields
at selection-screen output.
Loop at screen.
if screen-name = 'SALES ORG'. <<<Name of the parameter that you have declared
screen-input = 0.
modify screen.
endloop.
Similarly you can do for other fields too.

Set default value for parameter fields

Good day!
Situation:
1. I have 2 parameter fields in reports (dateFrom and dateTo)
2. Before running report in ASP.NET I change value this fields (dateTo = today, dateFrom = today - 3 days)
3.I use for this source:
foreach (ParameterField crParam in CrystalReportSource1.ReportDocument.ParameterFields)
                        CrystalDecisions.Web.Parameter crParametr = new CrystalDecisions.Web.Parameter();
                        string ParametrName = crParam.Name;
                        crParametr.Name = ParametrName;
                          crParametr.DefaultValue = ActionReportParameter.GetParametrValue(ReportName, ParametrName);
                         CrystalReportSource1.Report.Parameters.Add(crParametr);
4. And repurt run without request value parameter fields.
5. BUT!!! now I need request value parameter fields before report start running - I want set default values for filelds and offer user change its before report start run.
How do this?
Thanks

I believe you need to create your own parameter promt screen. Capture what the user entered and pass that to the report(?).
