Read elements of a table

HI all,
I have a table with about 100 rows and 6 columns. I want to read each and every element of the table for implementing some checks and using each of them individually further. Could you please help me, how to do so.
Cheers Umang

Hi,
use the following code choose one of them based on your requirement
code is based on the node called "Orders" and its Elements so you need to change this according to yours
for(int x=0; x<wdContext.nodeOrders().size(); x++)
            //Generic Approach
            IWDNodeElement element = wdContext.nodeOrders().getElementAt(x);
            Object obj = element.getAttributeValue("<Your Attribute Name>");
            //Typed Approach
            IOrdersElement element2 = wdContext.nodeOrders().getOrdersElementAt(x);
            String type = element2.getOrderType();

Get selected elements from a table

Hi all,
I have a requirement like i m enhancing standard component in that i have added one button on click of that i want fetch the selected line item from the table ( which is a normal table). selection mode is auto.
i tried with the following code.
DATA:lr_element TYPE REF TO if_wd_context_element,
lv_index TYPE i.
*--Get selected element
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
****Here itself its throughing dump because lr_element is initial***************
*--get selected element index.
lv_index = lr_element->get_index( ).
can any one help me what is the wrong.. else suggest me how to get the selected elements from a table....
Thanks in advance.

*--Get selected element
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
if lr_element is bound.
lv_index = lr_element->get_index( ).
endif.
Instead you can directly read the node if that row is a lead selected one.
lo_node = wd_context->get_child_node( name = 'EMP' ). "Emp is node name
lo_ele = lo_node->get_lead_selection( ).
or
lv_index = lo_node->get_lead_selection_index( ).
where is the above code written..is it written in OnLeadSelect event of the TABLE..
can any one help me what is the wrong.. else suggest me how to get the selected elements from a table....
As the selection mode is Auto there is no multiple selection..hence try to use the lead selection only.

Regarding Link to URL UI Element in a table

Hi All,
I am using "link to url" UI Element in a table column. I have mapped the column (i mean the "reference" property of "link to url" UI to a bapi node). Now, when I am populating the table, for some rows the bapi is not returning the url links. So, the column is getting disabled and not even showing the links for the rows which are getting the url link from the bapi.
Is there any way to set the mapping row wise, so that the rows which have data get enabled with the link and which do not have data will be disabled.
Also, can I make the whole table readonly, except for one column.
Please help me in this regard.
Regards,
Murthy.

Hi Armin,
Thank you very much. The problem is solved. 10 points for you.
Another Question.......
Can we make the table readonly, leaving just one column to select.(that is the column with link to url). Is it possible? If so, please tell me how....
Also, can you tell me the reason for the following exception.....
<b>com.sap.tc.webdynpro.progmodel.context.ContextConfigurationException: DataNodeInfo(CreateTemplateComp.Zad_Bapi_Get_Template_Details_Input.Output.T_Template_Details): structure field Ad_Height not found

FileDownload UI Element in a table

I'm tryign to use FileDownload UI Element in a table, but it seems not to work.
I have defined a binary, an IWDAttributeInfo and a IWDModifiableBinaryType attributes in the same context node of the table.
In wdDoInit() I wrote the following code:
for (int i=0;i<wdContext.nodeFileTab().size();i++)
try {
wdContext.nodeFileTab().getFileTabElementAt(i).setAttInfo(wdContext.nodeFileTab().getNodeInfo().getAttribute(IPrivateView_pdfView.IFileTabElement.T_FILE_DOWNLOAD));
wdContext.nodeFileTab().getFileTabElementAt(i).setBinaryType((IWDModifiableBinaryType)wdContext.nodeFileTab().getFileTabElementAt(i).getAttInfo().getModifiableSimpleType());
wdContext.nodeFileTab().getFileTabElementAt(i).getBinaryType().setFileName(wdContext.nodeFileTab().getFileTabElementAt(i).getFilename());
wdContext.nodeFileTab().getFileTabElementAt(i).getBinaryType().setMimeType(WDWebResourceType.PDF);
wdContext.nodeFileTab().getFileTabElementAt(i).setTFileDownload(this.getByteArrayFromResourcePath("/sapmnt/PCD/global/config/cm/etc/pdf/"+wdContext.nodeFileTab().getFileTabElementAt(i).getFilename()));
catch (Exception e)
wdComponentAPI.getMessageManager().reportException(e.toString(),true);
As result each row download the file in the last row. Is there any other way I can try?

Hi Anita,
you cannot set metadata at element level of a node. When you set the metadata ( example mime type or file name ) for a particular element in the node , it changes for all the element. So you are always getting the file for the last row. ( most recent set metadata ).
Try using the inteface IWDCachedWebResource for file download.
For each row add a button, and associate an action "DownloadFile" for it. Use the following "onAction" for the said action.
public void onActionDownloadFile(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDownloadFile(ServerEvent)
    int selectedIndex = wdContext.nodeFileTab().getLeadSelection();
    IPrivateView_pdfView.IFileTabElement file = wdContext.nodeFileTab().getFileTabElementAt(selectedIndex);
    try {
     IWDCachedWebResource webResource = WDWebResource.getWebResource(
          this.
          getByteArrayFromResourcePath("/sapmnt/PCD/global/config/cm/etc/pdf/"+
          wdContext.nodeFileTab().getFileTabElementAt().getFilename(selectedIndex),
          WDWebResourceType.PDF);
     wdComponentAPI.getWindowManager().createExternalWindow(webResource.getURL(),"Download File",true).open();
   catch(Exception e) {
     // take some action
     wdComponentAPI.getMessageManager().reportException(e.toString(),true);
    //@@end
Hope you get a solution.

How to get selection screen elements and its table reference of a report ?

halo experts
How can I get selection screen elements and its table reference of a report ? . I tried rs_refresh_from_select_options. But I am unable to get the table and field it is referring to
For eg if my selection screen 1000 is
parameters: p_carrid type spfli-carrid,
select-options :s-_connid type sflight-connid.
is there any Fm or method which gives me what are the screen elements( p_carrid and s_connid ) and what table( splfi and sflight ) and field ( carrid and conid )it is referring to ?

The following code is an example of how you might dynamically determine all your PARAMETERS and SELECT-OPTIONS variables at run time. The PARAMETERS and SELECT-OPTIONS only point to a dictionary element--not a specific table. Even though you may say "spfli-carrid" or "sflight-connid", the data type really references the dictionary type and not a specific table/structure.
REPORT ZTEST_PROG.
TABLES sflight.
DATA:
       screen_tab TYPE STANDARD TABLE OF screen,
       wa_screen TYPE screen,
       scrn_nm TYPE string,
       scrn_leftover TYPE string,
       l_type TYPE REF TO cl_abap_typedescr,
       typ_nm TYPE string,
       typ_pre TYPE string.
FIELD-SYMBOLS <fs_data> TYPE ANY.
PARAMETERS p_carrid TYPE spfli-carrid.
SELECT-OPTIONS s_connid FOR sflight-connid.
INITIALIZATION.
LOOP AT SCREEN.
    IF screen-group3 = 'PAR'
      OR screen-group3 = 'LOW'.
        APPEND screen TO screen_tab.
    ENDIF.
ENDLOOP.
START-OF-SELECTION.
LOOP AT screen_tab INTO wa_screen.
    ASSIGN (wa_screen-name) TO <fs_data>.
    l_type = cl_abap_typedescr=>describe_by_data( <fs_data> ).
    IF wa_screen-group3 = 'LOW'.
      SPLIT wa_screen-name AT '-' INTO scrn_nm scrn_leftover.
      TRANSLATE scrn_nm TO UPPER CASE.
    ELSE.
      scrn_nm = wa_screen-name.
    ENDIF.
    SPLIT l_type->absolute_name AT '=' INTO typ_pre typ_nm.
    WRITE:
             / 'Screen Name: ', scrn_nm,
             / 'DDIC Type:    ', typ_nm.
ENDLOOP.
When you get into defining internal tables you can determine those at run time with cl_abap_structdescr. The following is an example of how you might do that. You can loop through the "components_table" and evaluate each field of the structure in this way.
DATA: structure_reference TYPE REF TO cl_abap_structdescr,
      components_table TYPE abap_compdescr_tab,
      components_structure LIKE LINE OF components_table.
structure_reference ?= cl_abap_structdescr=>describe_by_data( any_structure ).
components_table = structure_reference->components.
I don't know if this answers any of your questions but I hope that some of it is useful.

Kindly someone give me the code for this...
This is very urgent..Kindly help...
Thanks in advance,

Hi,
Have you tried looking at the examples that come with the PDK for all of the HTMLB elements? From memory, there should be a small table example or 2 that have different types of columns shown similar to what you want - they have the full source code with them for you to look at.
If you are working in a portal, go to the Java Developer tab and I "think" there should be a tab linking to HTMLB documentation and examples - sorry I can't be more specific but I don't have access to a portal at the moment so am trying to remember.

Reading data from BSEG table with Non-key fields in where clause

Hi All,
    I have to read data from BSEG table based on WBS element field (PROJK). As I'm not passing key fields to WHERE clause system couldnt run the select statement. Since BSEG is a cluster table I cant even create secondary index on PROJK field.
   Could you please tell me, how to improve its performance.

By using package and fetch from BSEG table. gathering all other information to a final internal table.This will reduce the hit to database.And also try to put that data in hashed internal table which is it_bseg....then definetly improve the performance.

Is it possible for the JDBC Lookup in PI 7.1 to read other user's table?

Hi,
I have the requirement of using the standard JDBC Lookup in PI 7.1. The user setup in the receiver JDBC adapter is only a service user that has a read access on some tables that are owned by another user or schema. When I am trying to do the import of Table's metadata, I can only see tables that are owned by the user setup in the receiver JDBC adapter.
Is there any any ways on how the user used in the receiver JDBC adapter can read another user's table (given that it has read access) during the import of Table's metadata?
Thank you in advacne for any response.

How to get Index of a single element in a table

Hi Gurus,
I need to get the index number of the element in a table even if the row is not selected.
I've already searched the forum for this but all i'm getting are selected rows in the table. I need to get the index even if that elemen's row is not selected in the table.
Please advise.
Regards,

Hi,
Could you please specify what exactly you want to do?
You said you want to get the index of an element even if the corresponding row is not selected. But there might be more than one element where the correponding rows are not selected. So it would be better if you could be more specific about what you want to achieve.

How to insert a text edit UI element in a table

hi all,
I want a text edit UI element in a table .I do not want input field because text entered can be very long and whole text cant be seen then.Is there any way to increase the width of input field if i insert an input field ? or what can be other solution for this?

Hi Govind,
You can't insert Text Edit as a cell variant in table. But you can increase the 'Width' property of Input Field, say to 500px or as per your requirement, so that you can display the full text at one go. Or you can bind the 'Width' property to a context and set the width at run time as per the text length.
Thanks,

How to add a new data element for existing table filed(Primary key field)

Hi Experts,
How to add a new data element for existing table field(Primary key field)
For this filed ther is no foreign key relation ships and even check table.
while activating table it is giving message like below.
can you help any one to solve this and wil steps to add new dataelement for existing primary key filed of a table.
Check table (NAMING SPACE/TABLE NAME(EX:/TC/VENDOR)) (username/19.02.10/03:29)
Primary key change not permitted for value table /TC/VENDOR
Check on table /TC/VENDOR resulted in errors
Thanks
Ravi

Hi,
Easiest way is to download the table eg into an Excel table (if possible) or text table. Drop the table from the database. Build your table with the new key field. Build the database table again and fill it.
You can do it also over the database into a new table. Drop the old one. Build the enhanced one and fill it. Afterwards drop your (temporary) table.
Maybe there are other ways, but this works.
Success,
Rob

Reading Data from a Table With an Expert

Hi all - I'm trying to write an Expert in OWB that would read data from a table and create a new table based on that information. I have the table creation part down, but how can I read data from a table with an Expert? From what I've read, Experts only deal with metadata, and there is no mechanism in Experts to actually read data in the tables. Does OraTcl work in Experts? Has anyone ever came across this problem, and if so, how did you solve it? Thanks in advance for your time! - Don

Hi Don
Can also use Java and JDBC from within Tcl, see the routines in this file below, take modify or whatever;
http://blogs.oracle.com/warehousebuilder/ombora.tcl
source <dir>\ombora.tcl
set g_user scott
set g_upwd zzzzzz
set g_hostname localhost
set g_port 1521
set g_srvname ora111
oraconnect $g_user $g_upwd $g_hostname:$g_port:$g_srvname
oraselect "select * from emp" ""
As well as dumping the results to stdout (you probably want to comment that part out and change any other part you don't like), g_res is a ResultSet object you can use to do whatever.
Cheers
David
