Thanks in advance,

How to remove lead selection in table dynamically

I have a table in webdynpro which allows multiple selections of row. I have a button which is supposed to be clicked after selecting single or multiple rows. After clicking on the button I want to remove the lead selection of the selected rows (which is shown in golden color for each selected row) .
I tried REMOVE_SELECTED ELEMENTS and it works fine but only if i select the row by pressing CTRL. If i had selected a single row by just a mouse click (without ctrl) then it wont work.
THANKS

Hallo Amber,
If_wd_context_node has static attribute no_selection. use that to clear the lead_selection_index.
node->set-lead_selection_index( if_wd_context_node=>no_selection ).

Lead Selection does not work after setting filter for ALV.

Hi, Can you please suggest on below scenario :
I have a Node with a sub node in it .
I am using the supply function on Sub Node to retrieve the date based on Parent Node.
There are two ALV's to display parent and item data. The issue is when a filter(user defined filter) is done on Parent table, the supply function does not work. The value is that of the selected row before setting the filter. Even after removing the filter, the item data is stuck and does not change on Lead Selection.
One thing I noticed is if the child table is a table UI, there is no issue. The only problem is when the second table is ALV
Thanks In Advance

Hi Prashanthi,
Your issue can be resolved as below
Create an event handler method 'set_alv_data' for the event 'ON_LEAD_SELECT' of parent alv
Write the below code inside the event handler method
METHOD set_alv_data.
DATA lo_node TYPE REF TO if_wd_context_node.
DATA lv_path TYPE string.
DATA lv_index TYPE string.
lv_index = r_param->index.
CONDENSE lv_index.
CONCATENATE wd_this->wdctx_my_parent_node
lv_index
wd_this->wdctx_my_child_node
INTO lv_path SEPARATED BY '.'.
lo_node = wd_context->path_get_node(
      path                          = lv_path
DATA lo_interface TYPE REF TO iwci_salv_wd_table.
lo_interface = wd_this->wd_cpifc_alv_child( ). "get the ref of alv comp of child
lo_interface->set_data(
    EXPORTING
*    only_if_new_descr =
      r_node_data       = lo_node
ENDMETHOD.
The above code sets the data node of child alv based on lead selection of parent alv data.
Note: Replace 'parent_node', 'child_node' with your nodes & 'alv_child' with your alv component name of child alv.
If you want to control the data of child alv on filter function, you can use the event ON_STD_FUNCTION_AFTE and once you define the filter you get the r_param->id = 'SALV_WD_FILTER_DEFINE' & now you can clear data of child alv.
Hope this helps you.

Rama

Error "Lead selection not set for context node"

Hi everyone,
I've got a Tree control in WebDynpro ABAP and I've implemented an "expand all" button.
Here's the coding:

ENDMETHOD.
However I'm getting the error above: "Lead selection not set for context node".
Any suggestions?

hi developement Themis,
I think u didn't diclare "node" as context node. So declare it as a context node before using as a context node..as below
DATA node TYPE REF TO if_wd_context_node.
or u can use "lo_nd_child " as ur context node in ur program in place of "node"
then I think this error will be removed.

Remove Leading zeros for Material in Transformation

Hi Experts,
I'm using DTP first time. I don't have much exp on DTP & Transformations.
I'm creating infocube with some objects. I want to remove leading zeros for zmaterial.
In 3.x writen update routines as fallows:
data: zmat(18) type c.
zmat = COMM_STRUCTURE-/BIC/ZMAT.
shift zmat left deleting leading '0'.
result value of the routine
RESULT = zmat.
I'm confusing in Transfermation where to write this routines.
I'm writing in Transformation as fallows:
data: zmat(18) type c.
zmat = SOURCE_FIELDS-/BIC/ZMAT.
shift zmat left deleting leading '0'.
RESULT = zmat.
But it's getting remove zero's.
Anybody suggest on this.
Siri

Dear Sir,
No confusion at all.
Just double click on the Target Infoobjct i,e Material object in Transformation, you will see a wizard popping up.
There you will see a option called "RULE TYPE" and the default value will be "Direct Assignment". In the same check box click on the drop down icon and select "Routine".
The moment you select the routine option, it will open up ABAP workspace where in you can write your routine and get the desired result.
Hope it helps.

How to Disable the Lead selection Action on aTable n How to Refreh a Page

HI....
1)How to Disable the Lead selection Action on aTable n How to Refreh a Page r web dynpro application.
In my case i have a table n user enters data on multiple rows in table , n i have some input fields outside of table for those Inputs fields am settiing the data at the screen initilization(in Init() moethod by hard code).the problem is whenever the is clicking in th 2nd row of a table the Lead Selection is triggerig and the data in the Input Fields outside the table is not displayinig.
So by removing the lead Selection Action of a table i thought i can reslove this,
2) How to refresha page(like we click F5 on key board),is it can be done thru code in web dynpro application
Regards
Rajesh

Hi,
You did not explained what is your functionality or coding in leadselection. Is that action on leadselection is necessary for you?.
1)If you just want to remove the action then go to table properties and remove the action for leadselection.
2)If you still want to continue with your leadselect action, then what you can do is.. write the code in leadselection action to again set the input fields which are out from table. That is what you did in your init method.
Page Refreshing
3) What do you mean by page refreshing? is that refreshing your table only or both the table and input fields.
What I understood is you are allowing the user to enter values in table and soon after pressing a button the values should be saved and the data in input fields shld be deleted. For this if you only invalidate the node then the user entered data will be lost.
So what you do is after getting the input data from the user add it to a ArrayList and then invalidate the node which clears the data in input field. Finally bind the Arraylist to your node. see the following code. This is a concept make changes according to your requirement
ArrayList list1=new ArrayList();
wdContext.nodeAbc().bind(list1);
IPrivateExcelviw.IAbcElement ele = wdContext.createAbcElement();
ele.setNo(wdContext.currentAbcElement().getNo());
ele.setName(wdContext.currentAbcElement().getName());
ele.setMarks(wdContext.currentAbcElement().getMarks());
list1.add(ele);
wdContext.nodeAbc().invalidate();
wdContext.nodeAbc().bind(list1);
Revert me if you have any doubts

Removing leading zeros in a column

Hi,
I would like to remove leading zeros of a column in a table. My Questions :
1. Is it possible?
2. Where is it better to truncate, in RFC or Web Dynpro?.
3. If Possible, How can I do that.
I appreciate your input.
Thanks,
Sunita.

Hi Sunita,
Please specify the datatype of the column that contains leading zeros, because if the data type of the column is integer then the leading zeros are automatically taken care.
If your RFC return you int and you are assigning it to a String then the leading zeros will appear.
For example, see the below simple ABAP Program. Just copy and execute it. You will see the difference.
data: a type mara-matnr,
str type string.
select single matnr from mara into a.
write a.
str = a.
write / str.
Hope it helps you.

How to remove leading zeros from variable

hi,
   how to remove leading zeros from variable like it_vbap-matnr.
value in it_vbap-matnr is 000000000000000358
i want to remove leading zeros so that it become 358
regards
deepak

You can use Function Module <b>'CONVERSION_EXIT_MATN1_OUTPUT'</b>
This Function Module will eliminate leading Zeros.
For each MATNR Value read form DB Table,u can eliminate Leading zeros and then modify ur Internal table.
I think u will not get leading Zeros into utr Internal table when u read from VBAP.
Bcoz MATNR in VBAP itself have Conversion routine.
If u r getting leading zeros,U can use following Logic.
tables:
vbap.
data:
   t_vbap like standard table of vbap.
select matnr
from vbap
into corresponding fields of table t_vbap.
loop at t_vbap into vbap.
CALL FUNCTION 'CONVERSION_EXIT_MATN1_OUTPUT'
      EXPORTING
        INPUT         = vbap-matnr
      IMPORTING
        OUTPUT        = vbap-matnr
modify t_vbap from vbap transporting matnr.
endloop.
Hope this will work.....

Removing Leading Spaces in the field to be displayed

Hi,
Could you please tell me how to remove leading spaces in currency field in write statement?
the length of the field cannot be changed by writing fieldname(length).
is there any other method to do the same. the length should vary according to the amount in the field.
Ragards,
Krutika

hi,
please use "SPLIT " or condense .
eg: SPLIT wa_bseg-hzuon at space into wa_bseg1-hzuon l_space.
to better understand refer this code:
IF it_mhnd IS NOT INITIAL.
SELECT hzuon bukrs gjahr augdt augbl
FROM Bseg
INTO TABLE it_bseg
FOR ALL ENTRIES IN it_mhnd
WHERE belnr = it_mhnd-belnr
    AND bukrs = it_mhnd-bukrs
    AND gjahr = it_mhnd-gjahr
    AND umskz = 'E'.
endif.
data: l_space type char6.
loop at it_bseg into wa_bseg.
SPLIT wa_bseg-hzuon at space into wa_bseg1-hzuon l_space.
wa_bseg1-bukrs = wa_bseg-bukrs.
wa_bseg1-hzuon = wa_bseg-belnr.
wa_bseg1-hzuon = wa_bseg-gjahr.
wa_bseg1-hzuon = wa_bseg-umskz.
append wa_bseg1 to it_bseg1.
clear: l_space, wa_bseg1.
endloop.
IF it_bseg1 IS NOT INITIAL.
      SELECT belnr bldat
        FROM bsad into table it_bsad
        FOR ALL ENTRIES IN it_bseg1
        WHERE belnr = it_bseg1-hzuon
        AND   bukrs = it_bseg1-bukrs
        AND   augbl = it_bseg1-belnr.

Add and remove leading zeroes

Hi all,
       Iam having a requirement where in a enduser enters the vendor number and after pressing enter key it should display the vendor num along with vendor name concatenated in the same field. But the end user is provided the facility that he may not enter the exact vendor number ( I mean if vendor number is for example 0000055, the enduser may enter simply 55). The system should convert it with leading zeroes internally. And in display it should display removing leading zeroes.
like     input: 55              output : 55 Vendor_Name
my approach
iam using conversion_exit_alpha_input    for adding leading zeroes       before select query ( to fetch the vendor name for vendor number the user supplies)
before displaying the output after concatenation,
iam using conversion_exit_alpha_output.
after execution,
it is asking the exact vendor number . But in the output, it is giving the vendor number along with vendor name by removing leading zeroes ( as expected).
how to make the system accept the number without leading zeroes. please suggest me.
tthanking you in advance
regards
Bikash

Hi Bikash,
Since you have to display the Vendor number concatenated along with the Vendor Name, why do you need to use the Alpha Exit Function Module. As you have the Vendor number without the zeros in the input field, you can store it in a temporary variable and then once the Vendor name is available you can concatenate it along with the number in the same field.
If you need a code snippet, you can provide the Technical details of the fields of input. We can use the implicit ABAP    type casting feature to get the Vendor Number without any leading zeros.
Hope this helps.
Thanks,
Samantak.

ECATT abends during recording when lead selection is set to 0 on web dynpro

We have a web dynpro application that works ok when running by itself.   When we tried to record ECATT testing on it, it abended after we click on a selection from a list of values.    The error on the browser indicated an error on the "lead select".   After reviewing the dump, we found that it abends on an exception when the lead selection on the ALV is not set.   When we changed our code to set the lead selection to 1, the ECATT recording worked.
We have a requirement to set the lead selection of ALV to 0 so we need to change back our code.   We just did the setting to 1 just to get ECATT recording to work for now.    Does anybody know why ECATT requires this?   Is there a support packs that fixes this?
Here is a snippet from ST22 for more details on this:
Runtime Errors         UNCAUGHT_EXCEPTION
Exception              CX_WD_CONTEXT
Date and Time          2007/02/07 14:50:06
Short text
An exception occurred that was not caught.
What happened?
The exception 'CX_WD_CONTEXT' was raised, but it was not caught anywhere along
the call hierarchy.
Since exceptions represent error situations and this error was not
adequately responded to, the running ABAP program
'CL_WDR_CONTEXT_NODE===========CP' has to be
terminated.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred which is explained in detail below.
The exception, which is assigned to class 'CX_WD_CONTEXT', was not caught and
therefore caused a runtime error.
The reason for the exception is:
The lead selection has not been set. VIEW_TABLE
How to correct the error
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"UNCAUGHT_EXCEPTION" "CX_WD_CONTEXT"
"CL_WDR_CONTEXT_NODE===========CP" or "CL_WDR_CONTEXT_NODE===========CM00V"
"_RAISE_ELEMENT_NOT_FOUND"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

How to disable a lead selected item in a radio button group ?

Hi,
I have a radio button group and there are entries to create radio buttons dynamically. means there is only one radio button group in the UI design and in runtime I will be having two radio buttons (For ex: Yes and No ) . Now If I want to disable either Yes or No radio button, I am unable to do so. because If I disable the radio button group it disables both. So, I can have lead selected item for ex: Yes which I want to disable. I want to know specifically how this Yes button to be disabled by taking lead selected index item.
Please help.
Thanks
Praveen

Try setting the radio button value of the lead selected button to abap_false/space.

Hi ,
The onclick event provides you with a standard paramater "CONTEXT_ELEMENT" which has the element from which the event is triggered.
so you can declare this in the handler(if it is not there) and use it as follows.
CONTEXT_ELEMENT TYPE REF TO IF_WD_CONTEXT_ELEMENT an importing paramater.
DATA:
NODE_MODULE TYPE REF TO IF_WD_CONTEXT_NODE,
ELEM_MODULE TYPE REF TO IF_WD_CONTEXT_ELEMENT,
STRU_MODULE TYPE IF_V_MODULE=>ELEMENT_MODULE .

CONTEXT_ELEMENT->GET_STATIC_ATTRIBUTES(

STATIC_ATTRIBUTES = STRU_MODULE ). "Using the context_element paramater to get the static attributes.
NODE_MODULE->GET_STATIC_ATTRIBUTES_TABLE(

DELETE itab WHERE zmodule_id = STRU_MODULE-zmodule_id. "deleting the particular row from the table and binding it.
CALL METHOD NODE_MODULE->BIND_TABLE
