Hi Mani,
The sequential files (processed on application server) are called datasets. They are used for file handling in SAP.

What is open data set and close data set

what is open data set and close data set,
how to use the files in sap directories ?

hi,
Open Dataset is used to read or write on to application server ... other than that i am not sure that there exists any way to do the same ... here is a short description for that
FILE HANDLING IN SAP
Introduction
Files on application server are sequential files.
Files on presentation server / workstation are local files.
A sequential file is also called a dataset.
Handling of Sequential file
Three steps are involved in sequential file handling
OPEN
PROCESS
CLOSE
Here processing of file can be READING a file or WRITING on to a file.
OPEN FILE
Before data can be processed, a file needs to be opened.
After processing file is closed.
Syntax:
OPEN DATASET <file name> FOR {OUTPUT/INPUT/APPENDING}
IN {TEXT/BINARY} MODE
This statement returns SY_SUBRC as 0 for successful opening of file or 8, if unsuccessful.
OUTPUT: Opens the file for writing. If the dataset already exists, this will place the cursor at the start of the dataset, the old contents get deleted at the end of the program or when the CLOSE DATASET is encountered.
INPUT: Opens a file for READ and places the cursor at the beginning of the file.
FOR APPENDING: Opens the file for writing and places the cursor at the end of file. If the file does not exist, it is generated.
BINARY MODE: The READ or TRANSFER will be character wise. Each time n characters are READ or transferred. The next READ or TRANSFER will start from the next character position and not on the next line.
IN TEXT MODE: The READ or TRANSFER will start at the beginning of a new line each time. If for READ, the destination is shorter than the source, it gets truncated. If destination is longer, then it is padded with spaces.
Defaults: If nothing is mentioned, then defaults are FOR INPUT and in BINARY MODE.
PROCESS FILE:
Processing a file involves READing the file or Writing on to file TRANSFER.
TRANSFER Statement
Syntax:
TRANSFER <field> TO <file name>.
<Field> can also be a field string / work area / DDIC structure.
Each transfer statement writes a statement to the dataset. In binary mode, it writes the length of the field to the dataset. In text mode, it writes one line to the dataset.
If the file is not already open, TRANSFER tries to OPEN file FOR OUTPUT (IN BINARY MODE) or using the last OPEN DATASET statement for this file.
IF FILE HANDLING, TRANSFER IS THE ONLY STATEMENT WHICH DOES NOT RETURN SY-SUBRC
READ Statement
Syntax:
READ DATASET <file name> INTO <field>.
<Field> can also be a field string / work area / DDIC structure.
Each READ will get one record from the dataset. In binary mode it reads the length of the field and in text mode it reads each line.
CLOSE FILE:
The program will close all sequential files, which are open at the end of the program. However, it is a good programming practice to explicitly close all the datasets that were opened.
Syntax:
CLOSE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the CLOSE is successful or not.
DELETE FILE:
A dataset can be deleted.
Syntax:
DELETE DATASET <file name>.
SY-SUBRC will be set to 0 or 8 depending on whether the DELETE is successful or not.
Pseudo logic for processing the sequential files:
For reading:
Open dataset for input in a particular mode.
Start DO loop.
Read dataset into a field.
If READ is not successful.
Exit the loop.
Endif.
Do relevant processing for that record.
End the do loop.
Close the dataset.
For writing:
Open dataset for output / Appending in a particular mode.
Populate the field that is to be transferred.
TRANSFER the filed to a dataset.
Close the dataset.

Identifying Data sets

It's time consuming to identify the correct data-set for a particular set of fields you want to place on a BP screen. For example: I am trying to figure out what is the data-set for industries. I selected a view called 'Industry', but still it won't appear on the screen. I even referred to "calling application". Still could not. Also I referred to data-set in field grouping. Still not appearing on BP screen. So "Industries" data-set is what I am trying to place.
Can anybody throw some light on a method to figure out data-set for "Industries"

There's the stacking feature - Photo > Stacking > Stack by Capture time. However, that then stacks the image, so what I do is expand the stacks and mark the images with the green label which helps with smart collections or filtering and warns me in case I think one of the frames is badly-exposed and can be deleted. There's no magic bullet though.

Nested Left Outer Join : Data Set

Hi All
I am bit confused about data set used by Nested Left outer join.
Can anyone help me.
Here is sample data:
Tables (Name, 3 Column each, total rows and matched rows if any):
     Table 1
     A     B     C
     Total 20 Rows
     Table 2
     A     D     E
     Total 50 Rows and 10 Matching on      2.A = 1.A
     Table 3
     D     M     N
     Total 15 Rows and 15 Matching on 3.D = 2.D
     Table 4
     M     X     Y
     Total 20 Rows and 10 Matching on 4.M = 3.M
Sql
select *
From Table 1
Left Outer Join on Table 2 on
               2.A = 1.A
-- Data set 1 will contain 20 Rows (10 matching and 10 non matching)
Left Outer Join on Table 3 on
               3.D = 2.D
-- What will be data set? 20 Rows of Data set 1 or 15 Matching Rows?
Left Outer Join on Table 4 on
               4.M = 3.M
-- What will be data set? X Rows of Data set 2 or 10 Matching Rows?
Please have a look and clear my understanding.

select *

The join is including all rows from emp, just like you want.
The WHERE clause is discarding all of those rows. Since all the columns from emp_type (alias t) are NULL, the condition "t.type_id = 1" in the WHERE clause is never true.
Perhaps you meant to include all those conditions in the join conditions, like this:
select *
from emp e
left outer join emp_Type t
    on e.empid = t.empid
   and t.type_id = 1
   and t.end_date is null;Edited by: Frank Kulash on Jan 30, 2012 3:56 PM

On my mini ipad, I cleared the cookies/histories in the safari setting. But what does the advance-setting of the clearing the website data does? What's that used for? Thank you!

On my mini ipad, when I'm on the internet -- a few times I will see a blue small pop-up boxes telling me to allow down/load or add something like the bubble-splash game or something similar. I jusr click ignore and it goes away.. I'm not sure why it's showing up lately.. I'm not sure if it's a virus or hacked in or a web brower matter..
Should I go to the cookies/histories in the safari setting and have it cleared out? Will that help resolve that??
And what does the advance-setting of the clearing the website data does? Sorry, I'm not familiar.. what's is that used for? Should I use that feature as well?? Thank you!

This indicates corrupt files.
A restore should resolve.

[4712] WARNING!!! 'Huh, you set a test object to itself... whats up with dat?' Line 601 in function in file .\tstobj2\ObjArray.cpp

I'm using TestStand 4.0 and anytime I try to intialize my chasis this message shows up in my debugg viewer. I would appriciate any feedback. I have no idea what could be triggering this message or why it's worded the way it is.
[4712] WARNING!!! 'Huh, you set a test object to itself... whats up with dat?' Line 601 in function in file .\tstobj2\ObjArray.cpp

You've hit what was intended to be an internal development warning, but apparently the warning macro used is not compiled out in the release.
This has likely been there since TestStand 1.0 and is nothing to worry about. In most cases it indicates you've called SetPropertyObject or SetPropertyObjectByOffset to set an object that was already set in the specified location. This is a harmless NOP and the warning only appears in attached debuggers, but it "might" be an indication that you have made a programming error.
I launched and exited the 4.0 sequence editor without seeing this warning, so I don't know if it is being triggered by your code module (or sequence, or custom step type, or custom UI, or custom process model, ...) or another part of TestStand that you are using. Chances are good that this warning does not indicate a functional problem. However, if you can reproduce it with a clean uncustomized TestStand install, I'd like to know how you did it.
I've entered a corrective action request to remove this warning.

My calendar date is not automatically changing, what's the proper setting?

My calendar date is not automatically changing, what's the proper setting?

If the population of the ObservableList (independent of any UI considerations takes a long time, then you probably want to do the populations off the JavaFX application thread (e.g. via a javafx.concurrent.Task)).
If you do populate the list in a Task, standard threading cautions apply in terms of not updating items in the scene graph off the JavaFX application thread and ensuring that the system is absent of race conditions, etc.
Look over the documentation of http://docs.oracle.com/javafx/2.0/api/javafx/scene/control/Cell.html and that may help you.
The JavaFX controls such as ListView have been carefully designed to exhibit high performance even when backed by extremely large lists (through the concept of virtualization explained in the Cell documentation). For example, if the backing list is updated but the portion of the list being updated is not within the currently displayed list contents, (I would hope) the update would be very efficient.

What is data sets,parent data,child data in generic technology connector..

Hi All,
I am a new learner to OIM. Please try to give a brief details of data sets,child data,parent data,providers in Generic Technology Connectors..
Thanks in advance..

Description:
You get this error, if you are passing reserved key words to the XML Parser or the XML syntax is wrong.
Cause:
I suppose, you are getting this error from tcImportOperationsIntf's addXMLFile() method. From your error message it looks like, when a file is submitted to XML Parser during the import operation, syntax is wrong.
Solution:
Check the code that is generating the xml file. Easy way to test is : open the xml file in IE. If there is syntax error, IE will throw you the error.
Hope this helps you.
Cheers,
Raghavendra

Report Builder Wizard and Parameter Creation with values from other data source e.g. data set or views for non-IT users or Business Analysts

Hi,
"Report Builder is a report authoring environment for business users who prefer to work in the Microsoft Office environment.
You work with one report at a time. You can modify a published report directly from a report server. You can quickly build a report by adding items from the Report Part Gallery provided by report designers from your organization." - As mentioned
on TechNet.
I wonder how a non-technical business analyst can use Report Builder 3 to create ad-hoc reports/analysis with list of parameters based on other data sets.
Do they need to learn TSQL or how to add and link parameter in Report Builder? then How they can add parameter into a report. Not sure what i am missing from whole idea behind Report builder then?
I have SQL Server 2012 STD and Report Builder 3.0 and want to train non-technical users to create reports as per their need without asking to IT department.
Everything seems simple and working except parameters with list of values e.g. Sales year List, Sales Month List, Gender etc. etc.
So how they can configure parameters based on Other data sets?
Workaround in my mind is to create a report with most of columns and add most frequent parameters based on other data sets and then non-technical user modify that report according to their needs but that way its still restricting users to
a set of defined reports?
I want functionality like "Excel Power view parameters" into report builder which is driven from source data and which is only available Excel 2013 onward which most of people don't have yet.
So how to use Report Builder. Any other thoughts or workaround or guide me the purpose of Report Builder, please let me know.
Many thanks and Kind Regards,
For quick review of new features, try virtual labs: http://msdn.microsoft.com/en-us/aa570323

Hi Asam,
If we want to create a parameter depend on another dataset, we can additional create or add the dataset, embedded or shared, that has a query that contains query variables. Then use the option that “Get values from a
query” to get available values. For more details, please see:http://msdn.microsoft.com/en-us/library/dd283107.aspx
http://msdn.microsoft.com/en-us/library/dd220464.aspx
As to the Report Builder features, we can refer to the following articles:http://technet.microsoft.com/en-us/library/hh213578.aspx

SQL Update a Single Row Multiple Times Using 2 Data Sets

I'm working in tsql and have an issue where I need to do multiple updates to a single row based on multiple conditions.
By Rank_
If the column is NULL I need it to update no matter what the Rank is.
If the Ranks are the same I need it to update in order of T2_ID.
And I need it to use the last updated output.
I've tried using the update statement below but it only does the first update and the rest are ignored. Here is an example of the data sets i'm working w/ and the Desired results. Thanks in advance!
update a
set Middle = case when a.Rank_> b.Rank_ OR a.Middle IS NULL then ISNULL(b.Middle,a.Middle) end,
LName = case when a.Rank_> b.Rank_ OR a.Lname IS NULL then ISNULL(b.LName,a.LName) end,
Rank_ = case when a.Rank_> b.Rank_ then b.Rank_ end
from #temp1 a
inner join #temp2 b on a.fname = b.fname
where b.T2_ID in (select top 100% T2_ID from #temp2 order by T2_ID asc)

The Merge clause actually errors because it attempt to update the same record. I think this CTE statement is the closest I've come but I'm still working through it as I'm not too familiar w/ them. It returns multiple rows which I will have to
insert into a temp table to update since the resulting row I need is the last in the table.

OBIEE 11g BI Publisher; New Data Set Creation Error "Failed to load SQL"

Hi,
I'm trying to create a new SQL data set (from a client machine). I use "query builder" to build the data set. But when I click "OK", it fires the error "Failed to load SQL".
But strangely, if connect to the OBIEE server's desktop and create the data set it works without any issues. I wonder this would be a firewall issue. If so what are the ports I should open.
It's a enterprise installation. And we have already open 9703, 9704, and 9706.
Has anyone came across such a situation?

Talles,
First of all you might have more chance of getting a response over in the BIP forum. Other than that all I can think of is: is your MS SQL Server running with mixed mode auth?

Change master data setting - Vendor reconciliation account

Is it possible to change the configuration of a G/L account currently setup as a vendor reconciliation account (that has a balance) to a regular a balance sheet sheet account?
If yes, what actions do I need to do?
Are there any risks in doing this?
Can I perform a similiar change for a G/L account currently setup as a regular balance sheet account that I instead want to use as a vendor reconciliation account?
Thank you in advance!
Best regards Susan

Hello,
Answers to your questions:
Question:
It is possible to change a reconciliation account into a balance sheet account but the current items in the reconciliation account should be manually moved to another account
Answer:
If there is a single line item posted(whether the balance is zero or not), it WILL NOT allow you change the reconciliation account in the GL master record.
Question:
-New postings will however be posted to the new reconciliation account set up in the vendor master
Answer:
If you want to update a new reconciliation in vendor master, then create a fresh GL Account as reconciliation type for Vendor and update the vendor master with new GL Reconciliation Account. When you have done the new postings, new entries will flow to new Reconciliation Account, but the old entries will remain be there in the old reconciliation GL Account. To move the old reconciliation entries to new reconciliation entries executed F.5D (Balance Sheet Adjustment). Please read the documentation available on transaction code F.5D
Question:
-What inconsistency in data are you referring to below? - No Inconsistency
-What reports would these differences appear in? - No differences
-Is there any risk of making a balance sheet account into a vendor reconciliation account (when baalnces exist)? - Vendor Reconciliation Account is a Balance Sheet Account only. This is a liability account in your Trail Balance.
Hope this clarifies your doubts.
Regards,
Ravi

No data set found when creating a report

Dear all,
This is my first time using BI Publisher, and I am stuck at a very early stage.
I have followed the various steps described in the documentation, up to creating a new report.
When I try to do so, I fail as there is no available data set in the left panel.
Another curious behaviour is that I have first to export and then import sample data as xml for the sample to be saved. Otherwise, when I just click on 'Save as Sample Data', the sample file appears to be associated with the dataset, but disappears at the next logon.
What would cause such behaviours?
Are these issues linked?
Is it a configuration/setup issue?
Or could it be a privileges/roles issue?
Cordially,
Albain

Vitaly,
1. Yes, I checked "More Data Sources" - not there.
2. I tried adding the Field Definitions using Control Panel Add/Remove - no help.
I tried removing the "Field Definitions" and then adding them again - no help.
3. Another machine does have the same version of CR. It is running Vista. Problem machine is running XP.
4. Clicked the "Reinstall" button in the Control Panel Add/Remove - this fixed the problem. I did not need to uninstall the program.
Both machines now exhibit the same list of connection types (with one small exception). Thank-you for your hellp.
.... Warren

           Very urgent.Full marks will be alloted if u give me the correct answer.
Thanks,
Gopi.

Hi,
Due to serveral reasons
1. Check whether you have proper authority in the directory?
2. check the whether any files with same name?
3. use addition message in the open dataset statement so that you can know the system message it getting.
DATA: msg(100).
OPEN DATASET wa_BSEG_file FOR OUTPUT MESSAGE msg
IN TEXT MODE Encoding default.
