Creating a new column in SAP reports

Hi All,
I need to add a new column in, Financials --> Financial Reports --> Accounting --> General Ledger. When I try to create a column, it says Column already exists.
Kindly advise me if it is possible to add new columns in SAP reports.
TIA,
Satish. B.

Hi Satish,
you can't add a column to a system matrix using UIAPI - the only way is to add a userdefined field
And check this thread..

Try this. Execute the following in a SQL window started by a userid that has been granted the USER ADMIN system privilege:

Do a new layout on SAP NetWeaver Portal need more Performance?

Hello,
we want to create a new layout on SAP NetWeaver Portal in the Corporate Design of our company. Somebody said me, that a change from the standard layout needs a lot of more Performance on the server. Is that true?
At the present time our server already works very slowly with the standard layout. Is it useful to change the layout? Or do we need a better server for that?
Thanks in advance!
Best regards,
Ulrike Arndt

Hi,
It depend on how you design your layout.
Use standard light framework and design your layout without heavy weight components.
It increases the performance also.(a little b
it.)

Print data at new line in SAP Scripts

Hi,
Is there any way that i can print data at new line in sap scripts. I am looping my data and its printing in the same line but i need to print it at new line. Is there any formating options or any command to do that.
Thanks

Than you must take all the values from the internal table into the different variables and than print them.
In program:
READ TABLE ITAB INTO WA_TAB INDEX 1.
IF SY-SUBRC = 0.
VAR1 = WA_TAB-FIELD1.
ENDIF.
* read all the lines and fill the VAR variables
In SAPScript:
/E LINE_VAR
/P &VAR1&
/P &VAR2&
/P &VAR3&
/P &VAR4&

Thanks for Your response.
I followed the steps you mentioned. While doing that, it's asking for Read Only Db User ID & Password. If i give new ID & Password it gives the following information.
"A Read Only DB USER is assigned for all Company Database, Adding a read only DB user is irreversible. Do you want to continue"

How to add new folder in sap menu visible to all users

I want to add a new folder in sap menu. i can do it for my user id as it is user specific. I wanna know that how to add a folder so that every user able to see the same i.e irrespective of user-ids.

Hi Ramya,
This can be done in SAP menu instead of User Menu, provided all your users are using SAP menu. If a folder is created in User menu it would be visible only to the user. If it is created in SAP menu and if all the users are using the SAP menu then the folder would be visible to all...
Hope this clarifies your query...
Reward me points...

Adding new item in SAP logon

Hi,
when adding a new item in SAP GUI, we get an option for the connection type------
Custom application server
Group/Server selection
On selection the Group/Server selection
we need to add the System ID, Message server, SAP Router and Group/Server.
Here on adding the first two and then when i go on adding the Group/Server, I get the Error message as
Hostname <message server name> not found.
Is there anything i need to do in the HOST file or the Service file present at the Drivers folder of my local PC.

Hi Subhram
Firstly you need to check if connections to the specified servers are allowed through your network. Check if access is permitted on those group servers from your network.Check your VPN settings.
Secondly check the Saplogon.ini file in the C:\WINDOWS folder. Check if the entries are correctly maintained in there as well.
I hope this helps

Hi,
Read Data warehousing books written by Ralph Kimball or Bill Inmon in order to familiarize yourself with the basic concepts of data warehousing. This is the foundation of the entire thing.
Follow the SAP training materials on BW Data Warehousing, BW Reporting and BW Modeling. There are several books that can help you a lot when getting started. check this link
[http://www.amazon.com/SAP-BW-Book-List/lm/RRWM7R55RBEXQ/ref=cm_lmt_srch_f_2_rsrsrs2/103-7157721-8001426]
After you have a solid BW knowledge, start to review the help.sap.com site.
Hope this helps,
Regards,
Haritha.
