LineChart data tip won't display with single data point?

Hi,
I have a Flex 3 LineChart with LineSeries which use CircleItemRenderer. If there is only a single data point to display, the data tip is not displayed. If there are several data points, each data tip is displayed correctly.
How can I make the datatip appear correctly with even just one data point? Any workarounds for this problem?
Quick googling found that I'm not the only person with this problem. A suggested workaround is to use PlotChart instead, but I don't want to go there unless there is absolutely no good way to solve this problem directly.

Thanks for any clues!!

No one wanted to help me but I figured out that I was not referencing the DSN on the test server, only the local DSN.
The information to connect to the MSSQL database given by my hosting company was not correct for Dreameweaver (or MS Access) either.

Partitioning is possible with data(1 lakh records) or with out data

partitioning is possible with data(1 lakh records) or with out data...if with data, its compulsory to stop database..and its not possible to stop, but i want to partitioning my table for increase the performance...what can i do please help me.

"lahk" is not an internationally recognised term. Please use terminology that is recognised internationally.
You could create a table with partitioning, copy your data into it, then drop the original table and rename the new one to the old name (bear in mind any indexes on it), though this isn't ideal if you have primary/foreign keys etc.
Also, ensure you are licenced to use Partitioning. It is installed as part of the database as standard, but you have to have additional licence to actually use it in production.

Create prompt with date-filter and initialize it with current date

Oracle BI 11 g
Hi!
I need to create dashboard prompt with date-filter and initialize it with current date. How can I do that?
I tried to create repository initialization block and add variable. But I don't know what should I write to DataSource? I tried to use functions Now(), Current_Date, sysdate (for example, SELECT Now() FROM tbl_Calendar) but without results - when I pressed "Test..." button I got errors - something like "Now() is unknown function" or "Incorrect syntax near key word Current_Date".
After that I tied to use Presentation Variable in Prompt, but also without success ((
Please, help me.

I've created Repository Variable "CurrentDate", using SQL-query like this "select convert(varchar(10), getdate(), 104)" and now this variable is being initialized by value "07.04.2011". But I don't understand how to use this varible in DashboardPrompt! What item in list "Default selection" I should choose - "Variable Expression", "Server Variable" or something else? When I chose "Variable Expression" and write "CurrentDate" I got just string "CurrentDate" when preview Prompt. @{CurrentDate} gave me the same result.

PR date in MD04 to be displayed with past date. Even if req. is in past?

Hi All,
I have scenario where the raw material "X" has Order reservations in past let us assume month as May'11. The Procurement time is 10 days and GR time is 2 days and the Lot Size is EX. When we run the MRP in month of June the PR which will be created for Order reaservations will have the "Purchase Requisition" scheduled Forward with release date maintained as the current date and the delivery date as 10 Working days ahead of release date and Requirment date will add 2 more days. And This Requirment date will be displayed in MD04 in Date column. let us assume that we have excuted MRP on 17-June, then for all Past requirments the release date willl be 17-june and Delivery date will be 01-July and Requirment date will be 05-July based on setting said above (Rem: - Saturday and Sunday is holiday).
Client does not want to see the requirment date planned this way. He wants the date in MD04 for PR to be maintained in Past only.
is there any way to make this happen?
Edited by: ANIMESH KUMAR on Jun 17, 2011 7:45 AM

Hi Vivek,
But won't this Setting effect the Production order planning. I mean to say that Only PR should be planned this way, But Planned order must not be affected at all.

Multiple rows with single date

I am using a CDC control task to extract and load data from our OLTP source to our Data Warehouse.
For our Date dimension, we have a DateKey which is a
DATETIME stamp (created using SSAS dimension wizard). Time is always 00:00:00 as a DATETIME
value is required for populating the dates.
Our fact table destination uses this DateKey as a FK.
Our fact table OLTP data source contains multiple records with a single DATE and TIME field. This fine as I can convert the DATE field to a DATETIME using a derived column.
However, as our Date dimension has granularity of a day, all we require for our fact table is the most recent daily record from our OLTP data source.
At present, the data flow task is attempting to write all records and failing on PK constraint.
How would I go about traversing all records for each date and loading only the most recent for that day? Is there a better way to go about this?

If you wish to get only one record for today, you can simply use in your source query:
SELECT TOP 1 ... FROM OLTPdata ORDER BY DEATETIMEcolumn DESC
if you need one record for each date, you may use ranking functions:
WITH Q AS (
SELECT
ROW_NUMBER() OVER (PARTITION BY CAST(DateTimeColumn AS DATE) ORDER BY DateTimeColumn DESC, some tie breaker column) AS ROWNUM,
FROM OLTPData
SELECT * FROM Q WHERE ROWNUM=1

Validate the data in the internal table with the date in selection screen

Hi all,
I want to validate the data in the internal table and get only the records with the input date in the selection screen.
The date is in the select options and please let me know how to get the records only if it satisfies the input date in the selection screen.
Regards,
Shalem

For Ex.
SELECT-OPTIONS: S_DATE FOR VBAK-VDATU
If you want to read one INTERNAL TABLE record
READ TABLE it_tab(internal table name) WHERE vdatu(date field name in the internal table) = s_date
If you want to move more then one
LOOP AT it_tab WHERE vdatu = s_date.
Take the field values in another table and append it. then end loop.
you will get the records which only have the date in select option..
If you want detail code give me internal table name and select option name i will write you the code.

How to convert a string to date and then compare it with todays date???

Hello.
I want to set a format first for my dates
DateFormate df = new SimpleDateFormate("yyyy-mm-dd");
once this is done then I want to convert any string to date object in the above formate
String str="2001-07-19";
Date d = null;
try{
d = df.parse(s);
}catch(ParseException pe) {
pe.printStackTrace();
First of all there is something wrong above,cus what I get for this is
Fri Jan 19 00:07:00 MST 2001
where as it should have been
2001-07-19... to my understanding.
once this part is done I need to get current date in the above set format and compare the
current date and the date I set.
I will appreciate the help.
Thanks

for the output part:
a date is a point in time
the output depends on the format you specify for output
using for example a SimpleDateFormat.
You only specified the format for parsing (which is independent for that of output) so java uses some default format ... see the DateFormat.format() method for details.
for the comparison stuff, I just posted a little code snippet in this forum a few minutes ago.
the hint is: Date.getTime() returns milliseconds after a fixed date

How to display DB specific data in WEBI for users with Single Universe

hi,
I have a WEBI report which is based on Single Universe, which can support both Oracle and SQL Server databases.
There are 2 users for this report.
1) Oracle_User
2) SQLServer_User
When 'Oracle_User' opens report in InfoView, he should see the data from Oracle DB
When 'SQLServer_User' opens the same report in InfoView, he should see the data from SQL Server DB
Please let me know how to achieve this functionality.
Can we dynamically change the Universe connection based on the User who logged into InfoView..?
Thanks,
Vamsee

hi Anil,
Thank you for the response.
I have tried creating 2 connections and restricted each connection for each group, but in Infoview, only one group user is able to refresh the report, whose connection is exported along with the Universe. when the other group user tries to refresh the report, an error is displayed 'You donot have access the data from this Universe'.
So the reason is : 'As Universe can be exported to Repository with only one connection' that connection specific group user is able to access data from Universe Whereas other groupuser cannot( as other connection can't be exported along with the same universe).
As Universe can be exported to Repository with only one connection, how should these connections set for the corresponding groups?
Could you please provide me the detailed steps w.r.t connections restrictions...?
Thanks,
Vamsee

Favicon on MobileMe web site won't display with Safari - OK with Firefox

I have a web site published to MobileME using iWeb - I have added a favicon and updated HTML accordingly. Now after trying every combination of code and searching the Safari, iWeb and MobileMe forums I cannot figure out why my favicon will not display using Safari but will with just about every other browser (Firefox, IE, Netscape are the ones I've tried on a Windows PC - also won't dispaly using Safari for Windows). Any ideas???
I've put the favicon file in the web.me.com/pat.schafer/web/sites folder as well as the web.me.com/pat.schafer/web/sites/sitename folder and added the HTML ref code to every html file - I'm going crazy.

Hi Certified - tried your tips to no avail. I'm beginning to think it's some interaction (bug??) when using a site published to MobileMe (and iWeb?) and Safari. Note I also tried using Windows Safari on a PC which had never viewed the site and it still showed the Apple favico but as previously stated Firefox, and IE on this PC did show my favicon. (I have not tried to load Firefox on my iMac but may try this as well.) I'd try the Apple Support Center but I don't hold up much hope of their being able to assist - I was at the Genius Bar yesterday in the Sydney shop on another matter (broken mouse) and asked about this favicon issue and was told it was beyond the scope of what they can assist with.
Hello Old Toad - thanks anyway for the tip on the OVI slideshow - also thanks to your earlier tips on using OVI I did know about the trick of using a transparent shape but had got around to doing this - I'm still in the early stages of learning using iWeb ... the site in question is just a bit of a "sandbox". In fact I'm pretty much on my way to a bookshop to get a book an HTML and other web design technologies - clearly one must really understand the underlying technology to make these things work.

Pull the data from legacy System into report and display with SAP data

Hi Friends,
My requirement is-
Create report by processing data from SAP tables and prepare output.And Before displaying the output, I have to pull the data from non-sap system which is readymade (It will come as flat file with similar fields as Report structure has) and finally display the records from both SAP and Legacy System by filtering duplicates.

Steps:-
Define the file path on selection screen:-
Selection screen data
    select-options   (s_)
      parameters     (p_)
      radio buttons (r_)
      checkboxes     (x_)
      pushbuttons    (b_)
SELECTION-SCREEN BEGIN OF BLOCK block1 WITH FRAME TITLE text-f01.
parameter:    p_file    type text_512 obligatory.
Start-of-selection.
data : l_fname type string. " File Name
l_fname = p_file .
call function 'GUI_UPLOAD'
    exporting
      filename                = l_fname
      filetype                = 'ASC'
      has_field_separator     = '#'
    tables
      data_tab                = lt_data
    exceptions
      file_open_error         = 1
      file_read_error         = 2
      no_batch                = 3
      gui_refuse_filetransfer = 4
      invalid_type            = 5
      no_authority            = 6
      unknown_error           = 7
      bad_data_format         = 8
      header_not_allowed      = 9
      separator_not_allowed   = 10
      header_too_long         = 11
      unknown_dp_error        = 12
      access_denied           = 13
      dp_out_of_memory        = 14
      disk_full               = 15
      dp_timeout              = 16
      others                  = 17.
if sy-subrc <> 0.
    message e000 with 'Unable to upload file from the PC'(t13).
endif.
lt_data is of same structure as the fields in the file.
For filtering duplicates:-
delete adjacent duplicates from lt_data.
Now display the records using either ALV or using write statements.
You can display the records in any of the way you want.

System won't boot with incorrect date/time

Hey, I setup a computer back home for VNC, however there was a power outage and now the BIOS has reset. Unfortunately it defaults the date to 2099 for some reason, anyway now the computer won't boot (I can't remember the exact error). Anyway the trouble is I can't access that computer now, and it has no monitor hooked up, is there anyway I can force a boot with just keyboard and without setting the correct date in the BIOS (no one with access to the computer could do this).
Appreciate any help.

You can try to just press F1.
I have a similar issue with my home server, the battery on the motherboard is dead so when the pc is powered off for a while it will not remember the clock. When trying to boot the system in such a case it spits out an error where it offers to "ignore" the error if you press F1.
In my case I need to wait until my pc beeps before pressing F1, basically you need to get past the BIOS stage.
With a bit of luck it might work for you too.
Also I hope you have some ntp service running on your system to make sure the date gets set correctly on your system on bootup.

Table data needs to be displayed with horizontal and vertical lines

Hi,
I need to display the data of the table in the SAP script which is having both horiziontal and vertival lines.
the out put needs to looks as it in Excel...where there are multiple records with 5 fixed coulmns each seprated from one another by horizonalt and vertical lines..
Can you let me know how to proceed in SCRIPT ,,,, where the number of records might vary ..and also ..it might continue to second page..
Regards
Senthil

well it is possible but quite tricky.
All you got in SAP-SCRIPT to achieve this is the BOX-Statement.
The BOX statement works with variables for XPOS, YPOS, WIDTH and HEIGHT. what you need to do is:
- calculate those variables during runtime
- add box-statements with those variables.
to calculate those variables you need to count used lines and so on. i hope i showed you a way, rest is a lil brainwork then.

Graph display with no data

Hi,
Is it possible to display a blank graph or no graph if there is no data. The current graph does not contain any values to display and results with the specified rows/columns in Alt Text e.g.
Rows:
Series1
Series2
Series3
Series4
Series5
Columns:
Group A
Group B
Can anyone suggest the best work around?
Thanks

You can check the count of the records for and then display the graph accordingly.
Condition can be like below. Cant provide the exact one without seeing the xml and RTF.
<?if:count(current-group()[NUM!='NONE'])>0?>

SP2010: Different colors for chart bars in Chart Web part with single data series?

Hello,
I've been asked to create a chart for visual display and summary of Status values within a SharePoint list of job positions. The list of positions includes a Status field with the only values being Open and Closed. I created a page that shows the list, and
at the top I inserted a Chart Web part that displays two bars - one showing the number of Open positions and one showing the Closed positions. Because I was having difficulty getting the totals for each Status value to show up in the chart, I followed
the instructions at
http://highbrowse.wordpress.com/2012/07/04/chart-counts-from-sharepoint-lists/ and pointed my chart at the new "Status values" list - this worked well to display the sum counts for each of the two Status values in separate bars.
This was all fine and good, except that because I am only using one data series for my chart, both of the bars (for Open and Closed) show up as the same color. I've been asked to make them different colors but cannot figure out how to do so. Can someone
provide guidance on how I could make the two bars different colors? Thank you so much.
cheers

Hello,
as far as I know, the chart web part does not have any settings to change the color of individual data points or plot data points of a series in different colors. If you only have two values in the series, you could use a pie chart instead of the column
or bar chart. In a pie chart, the different slices have different colors.
cheers, teylyn
