Deletion of data of R/3 table using Web Dynpro

Hi Experts,
I have to delete some records from R/3 table CATSDB using Web Dynpro form. I am using BAPI_CATIMESHEETMGR_DELETE for this purpose. Can you please let me know the steps to accomplish this exercise.
I have displayed the records of CATSDB using one custom made BAPI. Using this BAPI, I am able to display the data. I have created one button called "Delete Data" button on the form. I have called BAPIs using following code:
public void onActionDeleteData(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDeleteData(ServerEvent)
    wdThis.wdGetTimesheetCompController().executeBapi_Catimesheetmgr_Delete_Input();
    wdThis.wdGetTimesheetCompController().executeBapi_Transaction_Commit_Input();
//@@end
However, when I am selecting the record and trying to delete the record, record is not getting deleted. Can you please help me in resolving the issues? What is going wrong?
Regards,
Brian

Hi Ashwani,
I have checked the BAPI - BAPI_CATIMESHEETMGR_DELETE. I am unable to delete the record using even R/3 screen. For deleting the record, I have to provide following four parameters:
PROFILE, TESTRUN, RELEASE_DATA and AGENT.
I don't know what should be the value of TESTRUN, RELEASE_DATA and AGENT. I know only the value of PROFILE. From ABAPers, I have come to know that in order to delete the reccord I must provide the value of COUNTER. However, the BAPI, BAPI_CATIMESHEETMGR_DELETE is not asking me to enter the COUNTER.
Can you please let me know how to delete the record from BAPI using R/3 screen. After that I will try to delete record using Web Dynpro application.
Regards,
Brian

How to create dictionary table using web dynpro?

Dear Experts,
Please clarify my doubts.Im new in this EP development.
Im using EP6 portal with NWDS6 for dev.
My Doubts are :
Im trying to develop a web dynpro application which captures some data and insert/update in Table.
=> If we create a structure Dictionary in web dynpro application will that automatically create the table in Portal database?
=> If it is automatically created how to insert or update that table.
can any one plz help.
thanks and regards,
Viswes.

Hi Visweswara
This will use the concept of EJB.
Refer these for creating Dictionary tables...
[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70929198-0d36-2b10-04b8-84d90fa3df9c]

As far as answer to your second question is concerned,
=> If u create a structure Dictionary in web dynpro application it will not create the table in Portal database..
You can access that table via creating a web dynpro iview in Portal..
Only application can accessed after deployment via iviews in Portal..
Thanks...

Adobe Forms - Table control data Saved in Database table through Web Dynpro

Hello Friends,
I Am facing a Problem in Adobe Forms through Web Dynpro.
i Want to Make Interactive online Adobe Forms - In Table Control user enter the multiple entry in the table control and after that Click on SAVE button , entry will saved in Database table.
Please guide me.
Thanks in advance.
Gaurav.

Hi Gaurabh,
For interactive form you have to check the property DisplayType = native and PdfSource should be a Context Attribute of type 'Xstring'.
For data retrieval, create a NODE and have all the required attributes within that node of AOBE form.
Fetch the data in WDDOINIT.
Also check, that the offline senario for this form is working.
Hope it helps you.

Retriving data using web dynpro

I want to make simple application whic stores data and retrive specified fields using web dynpro. can anyone provide tutorial link to do this

Hi,
The solution to this is very similar to the reports that we write.
1. Create a context node from the dictionary element in the view of the webdynpro component.
2. Now you may be displaying/editing this data in the form of a table in the view layout. For this create a table in the layout and bind the fields of the context to the node you created from the dictionary table in the context.
3. In the layout you also want to have a button SAVE. on the event of this button. Write the code from code wizard where in
a. Read the context of the dictionary table from the context.
b. call method
CALL METHOD lo_nd_group->get_elements
RECEIVING
set = lt_ddictable.
c. update the database table using the internal table lt_ddictable.
Hope you find this helpul.

Update cluster table from Web dynpro

Hi
I am trying to export data to a cluster table from web dynpro using this statement:
EXPORT zhr_sanct_st100 FROM zhr_sanct_st100 TO DATABASE zhr_clrm(ep) ID zhr_clrm-srtfd.
same piece of code work well if I include it in a report program through se38, but If I use it in Web dynpro, it doesnt update the cluster table and there is no error shown.
please reply ASAP.
Vishal kapoor

Thanks for your immediate reply. it worked this way:
IMPORT structure name TO structure name
FROM DATABASE cluster table name
TO wa_zhr_clrm
ID zhr_clrm-srtfd.
initially i missed to insert a work area wa_zhr_clrm, which has all the key fields of the cluster table.

How do u save datas more than one table using net beans ide using JSF

Hi,

I save / delete / update / New master table using POJO (Plain Old Java Objects), database - oracle and Toplink Persistence Unit.
How do u save data more than one table using net beans ide using JSF (I am using POJO) ?
and also Tell me the reference book for JSF.
Thanks in advance.

So, I am using net beans IDE 6.1 from sun microsystem. It is a free software.No, you don't drag'n'drop if you're new to JSF. Switch to source code mode. Write code manually, with the help of IDE for the speed up.
So, please guide me the reference books, articles. I need the basic understanding of JSF, net beans IDE.[JSF: The Complete Reference|http://www.amazon.com/JavaServer-Faces-Complete-Reference/dp/0072262400] is a good book. The [JSF specification document|http://jcp.org/aboutJava/communityprocess/final/jsr252/index.html] is also a good reading to understand what JSF is and how it works.

Can I restore the deleted statistical data from the database tables?

Hi all,
I have deleted the statistical data from the database tables like(Ex: RSDDSTAT, RSDDSTATWHM,..) by mistake through RSA1> Tools> BW Statistics for Infoproviders--> Delete.
Is there any way to restore the deleted data back? Thanks in advance.

Now I'm really confused-
Your first post said
"I have deleted the statistical data from the database tables like(Ex: RSDDSTAT, RSDDSTATWHM,..) by mistake through RSA1> Tools> BW Statistics for Infoproviders--> Delete."
but your last respsonse said
"I have deleted the BW Statistics data, not the actual data in RSDDSTAT tables through
RSA1 -> Tools -> BW Statistics for InfoProviders -> clicked 'Delete' bin to delete data."
If you used the RSA1 -> Tools -> BW Statistics for InfoProviders -> clicked 'Delete' - then you deleted the data from the RSDDSTAT tables. This assumes you accepted the default date range that would have popped up after the clicking on the Delete button which specified to delete thru the current date. If this is what you did, the data is gone. Your only hope is be to recover from a DB backup.
The data in the RSDDSTAT tables is what is used to feed the BW Statistics cubes, generally on a daily basis.

How can we delete the data in e-fact table.

how can we delete the data in e-fact table.

hii,
You cannot delete the request individually but you can one of the following:
1. Do a selective deletion from the cube. RSA1 -> Cube -> Contents -> selective deletion.
2. Delete all the data in the cube and then reconstruct only the required request ids. This would work only if you have the PSA available for all the requests.
3. Reverse posting is another possibility.
hope it helps,

Error while retrieving data from PL/SQL Table using SELECT st. (Urgent!!!)

Hi Friends,
I am using Oracle 8.1.6 Server, & facing problems while retrieving data from a PL/SQL Table:
CREATE or REPLACE PROCEDURE test_proc IS
TYPE tP2 is TABLE of varchar2(10); --declared a collection
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST(dt2 as tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
While executing the above procedure, I encountered foll. error:
ERROR at line 1:
ORA-00600: internal error code, arguments: [15419], [severe error during PL/SQL execution], [], [],
ORA-06544: PL/SQL: internal error, arguments: [pfrrun.c:pfrbnd1()], [], [], [], [], [], [], []

Can anyone please help me, where the problem is??
Is it Possible to retrieve data from PL/SQL TABLE using SELECT statement? & How ?
Thanks in advance.
Best Regards,
Jay Raval.

Thanks Roger for the Update.
It means that have to first CREATE TYPE .. TABLE in database then only I can fire a Select statement on that TYPE.
Actually I wanted to fire a Select statement on the TABLE TYPE, defined & declared in PLSQL stored procedure using DECLARE TYPE .. TABLE & not using CREATE TYPE .. TABLE.
I was eager to know this, because my organization is reluctant in using CREATE TYPE .. TABLE defined in the database, so I was looking out for another alternative to access PL/SQL TABLE using Select statement without defining it database. It would have been good if I could access a PLSQL TABLE using Select statement Declared locally in the stored procedure.
Can I summarize that to access a PL/SQL TABLE using SELECT statement, I have to first CREATE TYPE .. TABLE?
If someone have any other idea on this, please do let me know.
Thanks a lot for all help.
Best Regards,
Jay Raval.
You have to define a database type...
create type tP2 is table of varchar2(10)
CREATE OR REPLACE PROCEDURE TEST_PROC
IS
dt2 tP2 := tP2('a','b','c');
i NUMBER(8);
begin
SELECT COUNT(*) INTO i FROM TABLE(CAST (dt2 AS tP2));
DBMS_OUTPUT.PUT_LINE('**'||i);
end;
This will work.

Deletion of data from change log table and PSA

Hi,
For a DSO I want to delete data from "Chnage log table" and " PSA Tabel".
For the DSO manage screen I have seen " Environment-> " Delete changelog table" from this we can delete chnage log table data as per my understanding.
at PSA Level Mange screen also I have seen " Environment-> " Delete changelog table" from this option also it deletes the data from change log table or it deletes data from PSA table?.
if this option also deletes data from changelog table then how we can delete data from PSA table?
Please clarify me

Hi,
I am not sure what are you referring to from your point "PSA Level Mange screen also I have seen " Environment-> " Delete changelog table". When ever you click on manage for your psa you will be routed to a popup where you can see all your requests in the PSA table & there after if you click on any single request you will get Environment menu option but there wotn be any change log deletion option available. Please check again? Right clicking on your data source will take you to the manage requests for PSA. You can selectively delete the requests as required.
For DSO when you right click on manage you can directly find Delete change log data option in the Environment tab. there you can select the requests you want to delete.
Also if you want to automate the deletion process then you can simply create a chain and include the steps for PSA deletion & change Log deletion accordingly.
Also it is recommended to keep on clearing the PSA table & Chage log data at regular intervals as it saves the disk space & thus helping in performance optimization
Please refer the below doc at SDN, it will be helpful for you in automating the process of change log deletion & PSA deletion.

Adobe form to save data using Web Dynpro ABAP

Hi. I am pretty new to SAP world and trying to learn and work on a task given to me relate to
creating Adobe offline form using Web Dynpro ABAP same time.
I have several questions and hopefully, many gurus like you will provide answers.
I noticed there are many examples creating and using Adobe interactive forms (though not many newer version),
but I didn't see (at least I didn't find any) any detail example on saving data to an internal table (such as fixed assets, vendor master, etc)
using interactive form. Is there any detail explanation/example on this?
I have ask this question in another forum (before I found this forum) but didnu2019t get the answer yet.
2. When I tried to see graphic layout and modify the layout from Web Dynpro, I can't see the graphic layout.
All I see is text list of fields/buttons that I created, but can't see section for graphic layout where I can modify layout.
I am sure I didn't install/configure something correctly.
Anyone has any idea what I didn't do?
I have another question, but I will wait till later after I figure out above ones first.
Thanks for all your help in advance.
John

Hi John,
In the WD4A view, there is a button "Show/Hide Layout Preview".
Click on that button to be able to see the Layout.
Note that this button is next to the Pretty Print button.

How can I open a popup after clicking in a table cell using Web Dynpro?

Hello,
I am using Web Dynpro to create an application and I would like to click in a table cell and then a popup with confirmation appears.
I already have a table with the information that is displayed in the browser. In fact, I just added a column with images that are print icons.
My problem is that I don't know how to implement the method to set the action: when clicking on the print icon, a popup appears.
Thank you very much in advance.

HI Rafael,
Please check the below sample code
To quickly create dialog boxes of a standardized layout (for example, for the confirmation of changes to current data) you can call the CREATE_POPUP_TO_CONFIRM method of the IF_WD_WINDOW_MANAGER. You do not need to create a separate window for this. The dialog box is created automatically by the runtime.
●      The CREATE_POPUP_TO_CONFIRM method creates an object of the type IF_WD_WINDOW; the dialog box can be created using its parameters.
