Assuming your rig can support virtual machines, you can use Hyper-V and run another OS there.
Better practice however is to use a dedicated machine and use remote desktop to the server.

Please help me with the proper query for the below problem
Hi,
I have a table RATE which have two columns RT_DATE (date) and RATES(number).
This table have following data.
RT_DATE
RATES
1-JAN-2007
7
2-MAR-2008
7.25
5-JAN-2009
8
8-NOV-2009
8.5
9-JUN-2010
9
I wanted to get the rate of interest on 8-DEC-2009.
Output will be 8.5 as this given date is in between 8-NOV-2009 and 9-JUN-2010. Could you please help me with proper query?
Regards,
Aparna SHi,
That sounds like a job for the LAST function:
SELECT MIN (rates) KEEP (DENSE_RANK LAST ORDER BY rt_date) AS eff_rate
FROM rate
WHERE rt_date < 1 + DATE '2009-12-08'
MIN above means that, in case of a tie (that is, 2 or more rows with the exact same latest rt_date) the lowest rates from that latest rt_date will be returned. In rt_date is unique, then it doesn't matter if you use MIN or MAX, but syntax demands that you use some aggregate function there.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for your sample data, and also post the results you want from that data.
Point out where the statement above is getting the wrong results, and explain, using specific examples, how you get the right results from the given data in those places.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Hi All,
I have a number on the selection-screen.I need to prepare a structure with fields equal to the number provided on the selection screen.please help me with it.
Thanks in advance,
kushagra sharmaHi Kushagra,
Below is one way of doing it.
First create a dynamic internal table, taking number of fields from selection screen using cl_alv_table_create=>create_dynamic_table.
Then create a dynamic structure for that dynamic internal table.
Ex:
DATA:fcat_wa TYPE lvc_s_fcat,
fcat_itab TYPE lvc_t_fcat,
poi_itab TYPE REF TO data,
poi_itab1 TYPE REF TO data,
cha(4) TYPE c.
FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE,
<wa> TYPE ANY.
PARAMETERS: p_num TYPE i. " Number of fields
DO p_num TIMES.
cha = sy-index.
CONCATENATE 'F' cha INTO cha.
CONDENSE cha NO-GAPS.
fcat_wa-fieldname = cha.
fcat_wa-datatype = 'STRG'.
APPEND fcat_wa TO fcat_itab.
ENDDO.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
it_fieldcatalog = fcat_itab
IMPORTING
ep_table = poi_itab
EXCEPTIONS
generate_subpool_dir_full = 1
OTHERS = 2.
ASSIGN poi_itab->* TO <itab>. " Dynamic internal table
CREATE DATA poi_itab1 LIKE LINE OF <itab>.
ASSIGN poi_itab1->* TO <wa>. " Dynamic structure
Hope it helps u.

Here is the procedure
1. Create a new smartforms
Transaction code SMARTFORMS
Create new smartforms call ZSMART
2. Define looping process for internal table
Pages and windows
First Page -> Header Window (Cursor at First Page then click Edit -> Node -> Create)
Here, you can specify your title and page numbering
&SFSY-PAGE& (Page 1) of &SFSY-FORMPAGES(Z4.0)& (Total Page)
Main windows -> TABLE -> DATA
In the Loop section, tick Internal table and fill in
ITAB1 (table in ABAP SMARTFORM calling function) INTO ITAB2
3. Define table in smartforms
Global settings :
Form interface
Variable name Type assignment Reference type
ITAB1 TYPE Table Structure
Global definitions
Variable name Type assignment Reference type
ITAB2 TYPE Table Structure
4. To display the data in the form
Make used of the Table Painter and declare the Line Type in Tabstrips Table
e.g. HD_GEN for printing header details,
IT_GEN for printing data details.
You have to specify the Line Type in your Text elements in the Tabstrips Output options.
Tick the New Line and specify the Line Type for outputting the data.
Declare your output fields in Text elements
Tabstrips - Output Options
For different fonts use this Style : IDWTCERTSTYLE
For Quantity or Amout you can used this variable &GS_ITAB-AMOUNT(12.2)&
5. Calling SMARTFORMS from your ABAP program
REPORT ZSMARTFORM.
Calling SMARTFORMS from your ABAP program.
Collecting all the table data in your program, and pass once to SMARTFORMS
SMARTFORMS
Declare your table type in :-
Global Settings -> Form Interface
Global Definintions -> Global Data
Main Window -> Table -> DATA
Written by : SAP Hints and Tips on Configuration and ABAP/4 Programming

Smartform
you can check this link here you can see the steps and you can do it the same by looking at it..
http://smoschid.tripod.com/How_to_do_things_in_SAP/How_To_Build_SMARTFORMS/How_To_Build_SMARTFORMS.html
SMARTFORMS STEPS.
1. In Tcode se11 Create a structure(struct) same like the Internal table that you are going to use in your report.
2. Create Table type(t_struct) of stracture in se11.
3. In your program declare Internal table(Itab) type table of structure(struct).
4. Define work area(wa) like line of internal table.
5. Open Tcode Smartforms
6. In form Global setting , forminterface Import parameter define Internal table(Itab) like table type of stracture(t_struct).
7. In form Global setting , Global definitions , in Global data define Work area(wa) like type stracture(struct).
8. In form pages and window, create Page node by default Page1 is available.
9. In page node you can create numbers of secondary window. But in form there is only one Main window.
10. By right click on page you can create windows or Go to Edit, Node, Create.
11. After creating the window right click on window create table for displaying the data that you are passing through internal table.
12. In the table Data parameter, loop internal internal table (Itab) into work area(wa).
13. In table there are three areas Header, Main Area, Footer.
14. Right click on the Main area create table line by default line type1 is there select it.
15. Divide line into cells according to your need then for each cell create Text node.
16. In text node general attribute. Write down fields of your work area(wa) or write any thing you want to display.
17. Save form and activate it.
18. Then go to Environment, function module name, there you get the name of function module copy it.
19. In your program call the function module that you have copied from your form.
20. In your program in exporting parameter of function pass the internal table(itab).
SAP Smart Forms is introduced in SAP Basis Release 4.6C as the tool for creating and maintaining forms.
SAP Smart Forms allow you to execute simple modifications to the form and in the form logic by using simple graphical tools; in 90% of all cases, this won't include any programming effort. Thus, a power user without any programming knowledge can
configure forms with data from an SAP System for the relevant business processes.
To print a form, you need a program for data retrieval and a Smart Form that contains the entire from logic. As data retrieval and form logic are separated, you must only adapt the Smart Form if changes to the form logic are necessary. The application program passes the data via a function module interface to the Smart Form. When activating the Smart Form, the system automatically generates a function module. At runtime, the system processes this function module.
You can insert static and dynamic tables. This includes line feeds in individual table cells, triggering events for table headings and subtotals, and sorting data before output.
You can check individual nodes as well as the entire form and find any existing errors in the tree structure. The data flow analysis checks whether all fields (variables) have a defined value at the moment they are displayed.
SAP Smart Forms allow you to include graphics, which you can display either as part of the form or as background graphics. You use background graphics to copy the layout of an existing (scanned) form or to lend forms a company-specific look. During printout, you can suppress the background graphic, if desired.
SAP Smart Forms also support postage optimizing.
Also read SAP Note No. 168368 - Smart Forms: New form tool in Release 4.6C
What Transaction to start SAP Smart Forms?
Execute transaction SMARTFORMS to start SAP Smart Forms.
Key Benefits of SAP Smart Forms:
SAP Smart Forms allows you to reduce considerably the implementation costs of mySAP.com solutions since forms can be adjusted in minimum time.
You design a form using the graphical Form Painter and the graphical Table Painter. The form logic is represented by a hierarchy structure (tree structure) that consists of individual nodes, such as nodes for global settings, nodes for texts, nodes for output tables, or nodes for graphics.
To make changes, use Drag & Drop, Copy & Paste, and select different attributes.
These actions do not include writing of coding lines or using a Script language.
Using your form description maintained in the Form Builder, Smart Forms generates a function module that encapsulates layout, content and form logic. So you do not need a group of function modules to print a form, but only one.
For Web publishing, the system provides a generated XML output of the processed form.
Smart Forms provides a data stream called XML for Smart Forms (XSF) to allow the use of 3rd party printing tools. XSF passes form content from R/3 to an external product without passing any layout information about the Smart Form.
SmartForms System Fields
Within a form you can use the field string SFSY with its system fields. During form processing the system replaces these fields with the corresponding values. The field values come from the SAP System or are results of the processing.
System fields of Smart Forms
&SFSY-DATE&
Displays the date. You determine the display format in the user master record.
&SFSY-TIME&
Displays the time of day in the form HH:MM:SS.
&SFSY-PAGE&
Inserts the number of the current print page into the text. You determine the format of the page number (for example, Arabic, numeric) in the page node.
&SFSY-FORMPAGES&
Displays the total number of pages for the currently processed form. This allows you to include texts such as'Page x of y' into your output.
&SFSY-JOBPAGES&
Contains the total page number of all forms in the currently processed print request.
&SFSY-WINDOWNAME&
Contains the name of the current window (string in the Window field)
&SFSY-PAGENAME&
Contains the name of the current page (string in the Page field)
&SFSY-PAGEBREAK&
Is set to 'X' after a page break (either automatic [Page 7] or command-controlled [Page 46])
&SFSY-MAINEND&
Is set as soon as processing of the main window on the current page ends
&SFSY-EXCEPTION&
Contains the name of the raised exception. You must trigger your own exceptions, which you defined in the form interface, using the user_exception macro (syntax: user_exception <exception name >).
Example Forms Available in Standard SAP R/3
SF_EXAMPLE_01
Simple example; invoice with table output of flight booking for one customer
SF_EXAMPLE_02
Similar to SF_EXAMPLE_01 but with subtotals
SF_EXAMPLE_03
Similar to SF_EXAMPLE_02, whereby several customers are selected in the application program; the form is called for each customer and all form outputs are included in an output request
Advantages of SAP Smart Forms
SAP Smart Forms have the following advantages:
1. The adaption of forms is supported to a large extent by graphic tools for layout and logic, so that no programming knowledge is necessary (at least 90% of all adjustments). Therefore, power user forms can also make configurations for your business processes with data from an SAP system. Consultants are only required in special cases.
2. Displaying table structures (dynamic framing of texts)
3. Output of background graphics, for form design in particular the use of templates which were scanned.
4. Colored output of texts
5. User-friendly and integrated Form Painter for the graphical design of forms
6. Graphical Table Painter for drawing tables
7. Reusing Font and paragraph formats in forms (Smart Styles)
8. Data interface in XML format (XML for Smart Forms, in short XSF)
9. Form translation is supported by standard translation tools
10. Flexible reuse of text modules
11. HTML output of forms (Basis release 6.10)
12. Interactive Web forms with input fields, pushbuttons, radio buttons, etc. (Basis-Release 6.10) -

Please help me with the code!!
Dear All, I am going to simulate a TCP via UDP , and I have been asked for creating some specific methods , also additional helper methods are allowed but I can't avoid implementing any of the functions described below.
I have bold the functions which are ambiguous to me.
[click here to see the detail assignment explanation|http://www.net.t-labs.tu-berlin.de/teaching/ws0809/PD_labcourse/PDF/u5en.pdf|click here to see the detail assignment explanation]
If you see anything wrong please post , thanks.
• rdt connect()
This function sets all the parameters required for connecting to a server. Moreover, it opens a
UDP socket.
• rdt listen()
This function is the server-side counterpart of rdt connect(). It opens a UDP socket for
incoming connections and sets all the required parameters.
• rdt send()
This function takes an arbirary amount of data as input and writes it into a send buffer. It
does not send anything to the network.
• rdt recv()
This function returns the whole receive buffer. It does not really read data from the network,
but only from the receive buffer.
• rdt select()
This function does the whole work of moving data over the network. It behaves similar to the
system call select(), i.e. it blocks until there is some data in the receive buffer. The received
data can be subsequently read with rdt recv(). A flow diagram of the functionality of this
function follows:
– send all()
This function sends all the data in the send buffer over the network to the receiver. If
more than 500 bytes are present in the send buffer, more packets must be sent. The MSS
(Maximum Segment Size) of an RDT packet is 534 bytes.
*– select()*
This is the well-known system call that waits until the receive buffer contains data.
[ I don't know what to do with the buffer , and how to make it empty]
– recv from()
This is the well-known system all recv from() that reads data from the network.
*– statemachine send()*
This is a function that processes a newly received packet. In RDT 1.0 nothing is done here,
becuase the sender does not expect any ACK packets from the receiver.
– statemachine recv()
This function processes incoming packets. In RDT 1.0 the header is removed and the
payload copied to the receive buffer.
– Payload
rdt select() returns at this point if there’s any data in the receive buffer. If not, it starts
from the beginning.
[ where the data should be returned?]
This is my code:

Please Help me with the Work Item agent to agent forwarding error
hi folks ,
This is the error I am getting when I am trying to forward the work item from agent to agent.
"Work item 000000017188: Method SAP_WAPI_FORWARD_WORKITEM not allowed for type F "
Please Help in this regards. its Urgent.
thanks in advance for your help
Krishna ChaitanyaThe F type Workitem cannot be forwarded because it represents Workflow (Also Subworkflow) workitem Id.
You have to find out with workitem which has status W(Dialog Work Item; Represents a Single-Step Task) from SWWWIHEAD table and status should be in process and the TOP_WI_ID should be the value that you are trying to forward.

Is the some hardware or software settings that need to be adjusted?? Please help me quick, I need this running by tonite! (Party)
Thanks guys!maveric,
You can only run an optical cable from nForce to your Home Theater System if you have an Abit NV7-133R. It is the only nForce with Optical in/out. You need to use an RCA Cable to go from your nForce to your Home Theater.
Good Luck,
Richard
