A better way to delete IT2001 records in batch.,

Hi Gurus,
A little problem here. Due to data source error, I need to delete IT2001 records in batch.
Currently I am using standard report RPUREOPN to do this. But RPUREOPN will not update those deduction in IT2006 quota. So I've to delete & reupload cooresponding IT2006 quota data which is inconvenient.
Is there a better way to do this job? I mean deleting IT2001 in batch and also update the deductions in IT2006.
Thanks in adv!
Br,Kee

After running the report you mentioned above to delete absences/attn you can try running the report RPTUPD00 to revaluate the attendance and absence.

PDE-PLI031 Unable to fetch record from table tool_modulre

Dear ALL
I am creating PL/SQL Libraries in report builder.
but When I try to save the Library to database, a error
PDE-PLI031 Unable to fetch record from table tool_modulre.
Would you please tell me how to solve this problem
and why it coming
thankyou very much
pritam singh

Hi ,
Saving a library (.pll) to database would store the object inside specific tables that are to be created.
If you are using 6i, then you should find toolbild & toolgrnt.sql files which you have to run in the order specified. The above scripts creates the necessary tables and henceforth you won't get those errors while saving.
Hope this helps.
Thanks,
Vinod.

How to fetch records from the database into a combo box?

Hi:
I´m really new with ABLBPM and I´m trying to fetch records from the database to display them into a combo box as valid values for a presentation but I´m using a dynamic method with this code:
for each row in SELECT campo1, campo2 from TABLE
do
solicitudes[] = [row.campo1, row.campo2]
end
return solicitudes
And the debugger says that SQL instructions can be used only in fuctions and procedures that are executed on the server.
Do you know another way to do it?
P.D. Sorry for my terrible english
Greetings

Hi Steve,
Thank you, your idea is perfect, but when I try to run the screenflow where the combo should be filled I get this error:

Sender JDBC Adapter : Fetch records from multiple tables

Hi Friends,
I am using sender JDBC adapter to select few records from DB2 database table.
This scenario is working fine.
Now my requirement is to fetch records from 3 tables. These table are independent to each other. There is no primary key or foreign key.
Please let me know how to write the sql in sender JDBC adapter to fetch records from these 3 tables.
Thanks,
Sandeep Maurya

hi sandeep...
if the tables are completely independent and do not share any primary / foreign key relation ship...
why dont u think towards creating a seperate interface for each of them..
or if u still want to select from multiple table at once..the best way would be to write a stored procedure on the sender side which do all the fetching n processing and pass the final resultset to PI
or u can think towards fetching the data from 1 table and then in UDF do lookup from other tables..which again is tricky and performace intensive

JDBC Sender Adapter - NOT FETCHING RECORDS...

Hello Experts,
I know this was answered in a separate thread (JDBC Sender Adapter - NOT FETCHING RECORDS -PROCESSING STARTED).
However, my question is, Is there a way that we can be notified if a channel has stopped fetching records?
or is there a reporting tool that can be used to check/monitor if a channel is not processing any messages?
Thanks & Kregards,
allar

Hi Sreedhar,
Thanks for your reply.
These case is not being captured by our alert configuration because its not throwing any error.
in the communication channel monitoring, we see only something like this..:
3/16/09 8:25:19 PM Processing started
3/16/09 8:34:20 PM Processing started
3/16/09 8:33:55 PM Processing started
3/16/09 8:32:54 PM Processing started
but no error is being displayed nor sent.
Also, there was a case that the channel just stopped fetching, even though everything is active.
example log:
3/12/09 8:32:54 PM Processing started
We're looking for ways on how we can trap these scenarios as early as possible, get us notified and perform adapter-lock release when needed.
Regards,
allar

Time out error while fetching records from table BKPF

Hi,
I am fetching records from table BKPF using BUKRS & AWKEY in where clause. Query is as follows:
 SELECT BELNR XBLNR AWKEY
 FROM BKPF
 INTO TABLE L_I_BKPF_TEMP
 PACKAGE SIZE 500
 WHERE BUKRS LIKE L_C_EG
 AND AWKEY IN L_R_AWKEY .
 APPEND LINES OF L_I_BKPF_TEMP TO I_BKPF .
 ENDSELECT .
Program is giving time out error. There are 25628 records in range L_R_AWKEY , i m fetching 500 records at a time using PACKAGE SIZE. But the execution of prog stops on this query.
Please suggest something to overcome this problem.

Hi
Rui is right,
if you need to get the data by operation parameters u have to use the fields AWTYP and AWKEY.
In this selection u can omit the company code.
SELECT BELNR XBLNR AWKEY FROM BKPF
 INTO TABLE L_I_BKPF_TEMP
 PACKAGE SIZE 500
 WHERE AWTYP = <......> "<------------
 AND AWKEY IN L_R_AWKEY .
 APPEND LINES OF L_I_BKPF_TEMP TO I_BKPF .
ENDSELECT .

How can i fetch records from 3 tables in a single query without using join

Hi.
Can any body please tell me How can i fetch records from 3 tables with a single query without using joins
Thanx
prabhudutta

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

Writing OR query for fetching records

Hi,
I have dowloaded a custom wsdl and generated a java client from it using Jdeveloper.
I have a method named customObject1QueryPage(QueryInputObj) which is used to query the CRM oD to fetch records.
I have successfully queried using the above method for one condition:-
QueryInputObj param= new QueryInputObj();
QueryType q = new QueryType();
q.set_value("='" + "ABC'");
//q.set_value("LIKE 'A*'");
param.setAccountName(q);
customObject1QueryPage(param);
But now I want to query using "OR" condition with multiple names in the condition and I don't know how to
write query for that.
SQL query would be like "Select * from table where name='ABC' OR name='PQR' OR name ='XYZ' ";
I want to execute same query for CRM oD but have no idea how to write it.
Can somebody please help me as soon as possible.
Thanks.

Hi,
If your intent to Use OR Condition on a field with multiple Values
say, AccountName = 'xyz' OR AccountName= 'abc' the syntax would be *(='xyz') OR (='abc')*
say, AccountName = 'xyz' OR AccountName= 'abc' OR AccountName = 'pqr' the syntax would be *((='xyz') OR (='abc'))OR(='pqr')*
You can find similar example under On Demand Web Service Documentation

Fetch records from Database based on Input value

Hi Experts,
In my mobile application, I have designed one input field with F4 help or input assist. I need to fetch records from database based on that input and need to display records in table.
My question is:
How to fetch the records from database/back end based on the input value and display them as table format as we are doing in SAP ABAP?
Here, I need to fetch the records based on input value available in the UI screen and pass that value to gateway, fetch the records from database and need to bind with table in SAPUI5.
Kindly share the whole process flow with sample code for this requirement. Hope I have explained the requirement in detail.
Thanks In Advance..

Arindam Samanta.

Hi,
Try something like this.
In this, I am passing From date, To date, RelGrp, RelStr, Uname as input. Then I am storing those values in variables and passing this data in Odata request.
OData.read({ requestUri: "http://xxxx:8000/sap/opu/odata/sap/Z188_PO_SRV/pos?$filter=Docdate le datetime'"
                + todateformat+"T00:00:00' and Docdate ge datetime'"
                + fromdateformat+"T00:00:00' and RelGrp eq '"
                + relcode +"'and RelStr eq '"
                + relstg +"'and Uname eq '"
                + username+ "' "},
function (data) {
console.log(data);
When we are giving correct inputs it will goes to Success function and get the data from back end.
In console we can see the data.
Hope this will helps to you.
Thanks&Regards

How to fetch records with two recordset

i want fetch records from the table using two recordset like
ResultSet r1=stmt.executeQuery("select * from pf_data");
i want to take another recodeset
ResultSet r2=stmt.executeQuery("select * from finyr");
I am using Microsoft SQL server as my database.
I am also closing the recordset like r1.close();
then i cannot take two recordset at the same time.

Hi,
This is an example of a Top-N problem, and here's one way to do it:
WITH got_r_num AS
 SELECT item_id, supp_id, rnk -- RANK is not a good column name
 , DENSE_RANK () OVER ( PARTITION BY item_id -- Just guessing
 ORDER BY rnk
 ) AS r_num
 FROM table_x
 WHERE item_id = 2 -- If desired
SELECT item_id, supp_id. rnk
FROM got_r_num
WHERE r_num <= 2
RANK is the name of a built-in function in Oracle, so it will cause lots of trouble if you use it as a column name. (The RANK function is closely related to DENSE_RANK, used above.)
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Point out where the query above is giving the wrong results, and explain, using specific examples, how you get the correct results from the given data in those places. If you changed the query at all, post your code.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002

Hi,
1 ) What is exact audit log message ?
2) Try fetching the count in SQL statement if there are any valid records it will give the count.
May for testing you can use <TEST> in update statement.
3) Have you used taskTimeout parameter ?
4) Are multiple channels polling on same table ?

Fetching records in block

i already implemented one way that fetch all records (3 lakhs) one time , and process those in internal table .
But selecting 3lakhs records at one time abap application server giving timeout error.
some cofigraution required or what.
please guide me.
warm regards.

Hi,
what about doing it package by package ( 1 package = 1000 rows) and process the int. table as you like:
DATA: itab TYPE STANDARD TABLE OF SCARR WITH NON-UNIQUE
DEFAULT KEY INITIAL SIZE 10.
FIELD-SYMBOLS: <FS> TYPE scarr.
SELECT * INTO TABLE itab PACKAGE SIZE 1000 FROM scarr.
LOOP AT itab ASSIGNING <FS>.
... process it
ENDLOOP.
ENDSELECT.
Set the package size high enough that you have not many additional selects
(10.000 or 50.000 should be also ok).
Please be aware that the int. table is only defined inside the SELECT / ENDSELECT.
