Blank Table in Webdynpro

Hello,
I have developed a simple Webdynpro for java application which gets the Employee data based on the Employee Id but when I enter an id and click on the search button nothing displays in the table I have included on the screen.
I have placed relevant code in all the places and did the binding too.
Any help would be highly appreciated.

Hi
Your table may be coming blank due to improper binding of node or because your backed is not returning values properly. First check whether The BAPI or the DB Query that you are firing is returning any values.
Also post the code you have written.
cheers

ABAP Webdynpro: Creating a table on webdynpro screen to enter new data.

Hello Experts,
Does anyone know, how to create a table on webdynpro screen that can be used to enter new data in database?
I have tried to create a Table UI element (with Standard Cell Editor as Input Field) but it is "Display only" if there is no data in the table. This means, while you can use it to modify the data if some data already exist, but you cannot use it to enter new data if no data already exist. What I am looking for is something similar to a Table Control (or Step-Loop) functionalty of a traditional (non webdynpro) SAP screen. How to achieve this in Webdynpro for ABAP?
Thanks in advance.

Even if no data is not there, you can pass blank work areas to table, so now table will blank rows where you can enter the data even if previous data is not there.
below is the sample code to get blank rows in table in order to enter data.
DATA LO_ND_N_EDUCATION1 TYPE REF TO IF_WD_CONTEXT_NODE.
DATA LO_EL_N_EDUCATION1 TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA LS_N_EDUCATION1 TYPE WD_THIS->ELEMENT_N_EDUCATION1.
navigate from <CONTEXT> to <N_EDUCATION1> via lead selection
LO_ND_N_EDUCATION1 = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX_N_EDUCATION1 ).
DATA: ET_DATA TYPE WD_THIS->ELEMENTS_N_EDUCATION1,
EW_DATA TYPE WD_THIS->ELEMENT_N_EDUCATION1.
DO 10 TIMES.
APPEND EW_DATA TO ET_DATA.
ENDDO.
get element via lead selection
LO_EL_N_EDUCATION1 = LO_ND_N_EDUCATION1->GET_ELEMENT( ).
LO_ND_N_EDUCATION1->BIND_TABLE( NEW_ITEMS = ET_DATA SET_INITIAL_ELEMENTS = ABAP_FALSE ).
now table will have 10 rows, here node name is N_education1.
Thanks and REgards

Timeout Short Dump on a Data Query to a blank table.

Hi,
My program gives a short dump on quering a blank table. The dump says timeout.
what could the possible problem be.
regards,

Runtime Error          TIME_OUT
       Occurred on     02/19/2009 at   10:35:35
Time limit exceeded.
What happened?
The program "SAPLE31C" has exceeded the maximum permitted runtime without
interruption, and has therefore been terminated.
What can you do?
Print out the error message (using the "Print" function)
and make a note of the actions and input that caused the
error.
To resolve the problem, contact your SAP system administrator.
You can use transaction ST22 (ABAP Dump Analysis) to view and administer
termination messages, especially those beyond their normal deletion
date.
Error analysis
After a certain length of time, the program is terminated. In the case
of a work area, this means that
- endless loops (DO, WHILE, ...),
- database accesses producing an excessively large result set,
- database accesses without a suitable index (full table scan)
do not block the processing for too long.
The system profile "rdisp/max_wprun_time" contains the maximum runtime of a
program. The
current setting is 5400 seconds. Once this time limit has been exceeded,
the system tries to terminate any SQL statements that are currently
being executed and tells the ABAP processor to terminate the current
program. Then it waits for a maximum of 60 seconds. If the program is
still active, the work process is restarted.
successfully processed, the system gives it another 5400 seconds.
Hence the maximum runtime of a program is at least twice the value of
the system profile parameter "rdisp/max_wprun_time".
How to correct the error
You should usually execute long-running programs as batch jobs.
If this is not possible, increase the system profile parameter
"rdisp/max_wprun_time".
Depending on the cause of the error, you may have to take one of the
following measures:
- Endless loop: Correct program;
- Dataset resulting from database access is too large:
Instead of "SELECT * ... ENDSELECT", use "SELECT * INTO internal table
(for example);
- Database has an unsuitable index: Check index generation.
You may able to find an interim solution to the problem

Access ABAP table in Webdynpro Java application

Hi All
Is it possible to access ABAP table in Webdynpro Java application
Please provide your input
Thanks
Karthi D.

Hi you will connect to the remote SAP system, the
backend, using an Adaptive RFC MOdel. To access database tables, you can make use of existing functions in terms of RFC function modules. For each function module you need, the system generates a corresponding Java proxy class. All the generated proxy classes and interface are bundled together in the RFC model and treated as part
of your Web Dynpro project
In WebDynpro java you RFC by using Model :
Adaptive RFC Model
1. automatically adapts to changes in function module signature
2 provides support for data types and extensibility
3.support for different structure definitions in different backend
systems (release dependent structures, custom adaptation)
Basic principles and guidelines

Make entries in a table in webdynpro abap

Hi all,
We have a requirement to make multiple entries in a Table in webdynpro ABAP.
We have created a table and inserted inputfield as cellEditor
but at runtime it is being displayed in readonly mode we cannot enter anything in that inputfield.
inputfield is binded with a context and table is not in readonly mode.
Please help in this regards
thanks & regards.....
Gaurav Makin

Hi Gaurav,
Make sure the context node bound to the table has cardinality 0..N.
When the app starts you probably need to read the table contents from the database or some other source and populate the contect node.
The table will allow the user to edit values only for the rows that have a corresponding element in the context node.
If the initial content is empty, i.e. no elements in the context node then the user will not be able to edit.
You will need to either initialize the context node with a bunch of elements if the number of entries is fixed and known beforehand, or provide a way for the user to create a new row.
You can do this by adding a toolbar to the table with a create button with a CREATE action and the following method:
method onactioncreate.
data:
lo_element type ref to if_wd_context_element,
lo_node type ref to if_wd_context_node.
lo_node = wd_context->get_child_node( name = 'your node name here' ).
lo_element = lo_node->create_element( ).
lo_node->bind_element( new_item = lo_element set_initial_elements = abap_false ).
endmethod.

Please advice,
RTF template associated with PO Output for Communication (tempalte uploaded). When previewed,
data displays correctly.
When output is viewed from Application, additional blank table cells are added in header area.
These blank table cells are unwanted.
Also :
If I have multiple pages of output, the application is losing the header and footer after the
first page.
If I preview the template from Microsoft Word with the same output, the header and footer shows on
all pages.
Customer said:
'not looking for help designing the template - I have a template that gives
different output when output is viewed in the template builder and compared against the output from the application.
I am looking for assistance on which output is incorrect, and what cna be done to ensure both outputs are consistent'

Merge Cells in a blank table

Can anyone tell me how to merge cells in a blank table. For example - while making the table I may need 3 column in one row and only 2 in the next row. So I merge the cells. I have a laptop and am taking my right index finger and directing the mouse to the cell and then moving and tapping on the adjacent cell with my left index - but I must be doing something wrong because 9 out of 10 times it doesn’t work and I can’t figure out what I’m doing wrong. I’m pulling my hair out.
THANK YOU

Zaby,
You might find it easier to select one cell and then Shift-Arrow to extend the selection.
I assume that you are just making some kind of form and won't ever want to sort the table. Merging and Splitting cells can gum up the works for subsequent operations, so think before you choose that solution to your formatting problem.
