Row to Column mapping

Hi Team,
I have data like below
Table Name Line_Item
Column are
Product_name--------Mapping ID--------Values
ABC-----------------------344-----------------------3
ABC-----------------------345-----------------------Months
BCD-----------------------346-----------------------1
BCD-----------------------347-----------------------Year
Mapping ID is constant value not change in this but values will change ..
my output should be like below format
Product_name--------Period-----------Values
ABC--------------------3--------------------Months
BCD--------------------1--------------------Year
Thanks for you advance ....

Thanks for you response.
Grey, for a product we have only 2 value i.e(ABC product we have 3,Months mapping)
we don't get the below format of data.
ABC-----------------------344-----------------------3
ABC-----------------------345-----------------------Months
ABC-----------------------346-----------------------4
ABC-----------------------347-----------------------Weeks
we get the data like
ABC-----------------------344-----------------------3
ABC-----------------------345-----------------------Months
ZYX-----------------------346-----------------------4
ZYX-----------------------347-----------------------Weeks
OUTPUT should be below
ABC-----------------------3-----------------------Months
ZYX-----------------------4-----------------------Weeks
Please let me know if you have any concerns

Mapping of JTable Rows and columns and paint it to the JPanel

Hi,
I am using JTable and graphics object to draw the JTable on JPanel. But due to some lack of measurement I am not able to draw table cells correctly.
Apart from this on changing the fontSize I have to redraw it according to the requirement. But when the data size increases it draws absurdly.
I am using jTable.getCellRect() api to get the row width and height. Please help to redraw a JTable cell row and height on JPanel.
I am also attaching a sample code with this mail.
Thanks,
Ajay

an easy way would be to use setSize()

Map CdC op transform SEQUENCE and ROW oper column properties

I am using Map_cdc_op transform, for sequence column and row operation column properties, what fields should i choose?
My source table has the following columns:
RMID - primary key int
RMName - varchar
created_date datetime
Last_updated datetime
target table also has above 4 columns plus one rmLogID column with int data type. which is key column in target.
does map_cdc_op transform also take care of the surrogate key column id in target? which is "rmlogid".
thank you very much for the helpful info.

Suneer I am using SQL serverdatabase, this table is dragged to workspace as source:
RMID - primary key int
RMName - varchar
created_date datetime
Last_updated datetime
My task is to capture data changes from this table to target table, for that i a using Map_op_CDC transform, now under the properties SEQUENCE and ROW oper column what fields should i pic.I never used this transform before.
RMid is the primary key in source, rest teh of teh fields are changeable. i track created_dt and last_updated dates for that row.
Thanks a lot for the helpful info.

Need help with Pivoting rows to columns

Hi,
I need help with pivoting rows to columns. I know there are other posts regarding this, but my requirement is more complex and harder. So, please give me a solution for this.
There are two tables say Table 1 and Table 2.
Table1
name address email identifier
x e g 1
f s d 2
h e n 3
k l b 4
Table2
identifier TRno zno bzid
1 T11 z11 b11
1 T12 z12 b12
1 T13 z13 b13
2 T21 z21 b21
2 T22 z22 b22
As you can see the identifier is the column that we use to map the two tables. The output should be like below
output
name address email identifier TRno1 zno1 bzid1 TRno2 zno2 bzid2 TRno3 zno3 bzid3
x e g 1 T11 z11 b11 T12 z12 b12 T13 z13 b13
f s d 2 T21 z21 b21 t22 z22 b22
Also we do not know exactly how many TRno's, zno's, etc each value in the identifier will have. There may be only 1 TRNO, zno and bzid, or there may be four.
All the values must be in separate columns, and not be just comma delimitted. There are also other conditions that i have to add to restrict the data.
So, can you please tell me what is should use to get the data in the required format? We are using Oracle 10g. Please let me know if u need any more information

Something like this ?

How to transpose the data records (rows) to column(lists) using apd

Hi,
how to transpose the data records (rows) to column (lists) using apd in sap bw.
I do not want to use abap routine.only use the transpose rows to list transformation .
Pls provide the step by step procedure .
thanks,
Nimai

Save youe file to transpose as a csv and in the header row of your file for the columns you want to transpose you need to put some soer of a tag before the column name (ie your colum header was for a period budget will be something lie 2011001:ZFIBDD)
1. You will need to create a new apd process (rsanwb)
2. Insert a "Read from Data File" data source object and map it file (,csv)
3. insert a transpose object into your apd process (middle row 4th one over in the transformations section)
4. under the definition tab in the transformation object select all the columns that are to be transposed into rows and move them to the transformed area, the grouping fields section should contain the rows that you want to now be columns
5.under the transformation tab enter in the seperator you selected under the Field Name/Infoobject area (ie. ZFIBDD)
6. under the details tab you need to enter in all the fields to be transformed and tner the transposition field (ie ZFIBDD)
7. Then you can insert a set of transformations and a DSO and link the newly transposed fields into that.
hope that helps

Column Mapping while loading data via tab delimited text file

While attempting to load data I get an error message at the "Define Column Mapping" step. It reads as follows:
1 error has occurred
There are NOT NULL columns in SYSTEM.BASICINFO. Select to upload the data without an error
The drop down box has the names of the columns, but I don't know how to map them to the existing field names, I guess.
By the way, where can I learn what goes in "format" at this same juncture.
Thanks!

You can use Insert Into Array and wire the column index input instead of the row index as shown in the following pic:
Just be sure that the number of elements in Array2 is the same as the number of rows in Array1.

About the number of rows used to map data in Xcelsius

Hi Everyone:
I am using web services to fetch data into Xcelsius. The information I got from web service will increase in time and what I suppose is when I run out of rows to get all data I must open my Xcelsius model and select a greater range of rows on each component to get all the data that the web service is bringing.
Is there an alternative to avoid modifying ranges of data in crontrollers when rows mapped are not enough for the data you are fetching from a web service?
It is a bit confusing, I hope I've been clear enough. I really really will appreciate your opinions. If possible give me technical explanations.
Thank you,
Skull
Edited by: skull_buck on Aug 6, 2009 7:40 PM

Hi Greg
Thanks for your fast reply.
What you suggested is exactly what I am doing now, and also I increased the number of rows allowed to map en Xcelsius which are 512 by default.
I would like to know now, how many rows are advisable to increase? Because I am using some components and you must specify for each one a certain number of rows.
I test mapping 3000 and even 6000 rows but the model is too slow and I was not able to export the swf file in any format.
Thank you again,
Skull

I installed the Forms6i with the patch 12 on Windows XP platform. The installation language is Greek. The only problem i have faced up with the installation is the appearance of some question marks in LOV Column Mapping window ... instead of the Greek translation of the phrases:
Column Names ,
Return Item ,
Display Width ,
Column Title
Is there a specific Windows font that should be installed ....or something else...????
Thanks,,,,

You have to do it from the source code. Click on source, you will find "<xsl:if test="">".
Define your condition in test="/tns:input1=/tns:input2" or check if you source string contains "abcd", i.e. xsl:if test="contain(/tns:source_column1,'abcd')"
hope this will help

How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank

How to accessing current row report column value in Lov Query?

Hi,
which access methods (eg. bind variables, substitutions, ...) for getting the current row report column value can be used in the "Lov Query" property of a report column?
As what I know of and what I have read on the forum there are no bind variables for the report columns. For the "Link Text" property it seems that the column values exist as substitution strings (#COLUMN_NAME#). But they don't work in the Lov Query. => And would be good because of a hard parse each time the Lov query is executed.
The following post (Re: Simulating a correlated sub query in lov
is showing a solution to use package variables for temporary storage of the referenced value, but the only problem with that solution is that if a new record is added with the "Add rows to tabular form" process the package variable still contains the value from the last queried row! Is there a way (variable, APEX package, ...) to determine if the lov query is executed for a new record so that the package can return null?
I know that I could write the package in a way that the value is immediately cleared when lov_pkg.keyval is called (one time read), but then I would have to create several variables if I'm accessing the value multiple times in the query or in another query => I think an one time read solution would be very obscurely.
Thanks for your help

Hi Patrick,
I agree that it's a waste to continually use Ajax to go back to the server to get the contents of a dynamic select list.
There are no bind variables for any row item - but what you do have, as per my previous post, is the value of the data entered by the user in the first row. You can pass this into your application process (using get.add("VARIABLENAME", value)), which can use it to retrieve the correct LOV in your Ajax code - this will give you a "bind variable" that your process can use.
What you could do, however, is generate hidden select lists on your page - one for each possible LOV list and replace the contents of the new row's select list with the contents of the appropriate hidden select list. This is easy to do with javascript (using innerHTML functions). Obviously, though, the usefulness of this depends on the number and size of the select lists.
Even if you don't generate them to start with, you can keep a copy of any select lists returned by Ajax in the DOM for use on new rows. So, if you have retrieved a select list, you will have a copy of it in DOM which you can then copy into the new row. If you don't have the list in DOM, use Ajax to get it, store a copy of it and copy it into the new row.
Which method you use will depend on the number/size of select lists needed. If they are few in number and/or size, I would suggest generating hidden lists. If they are large, use Ajax to get them once, store them and then retrieve them from the DOM when needed.
There is another thread here where Arie recommends going to the server every time to make sure you get the most up-to-date data for the lists. If you want to follow this advice, for this reason, use get.add("VARIABLENAME", value) to pass the value to your process. If this is not an issue, you can use one of the other methods I outlined above.

Andy

Row Selector column on Interactive Report

Hi all,
I have an interactive report based on a custom SQL query. How do I add a row selctor column so I cans select individual rows? I have also tried using a tabular form which also does not display a row selctor column. This is odd as my other tabular forms display a row selctor column.
Many thanks for you help,
Chris

Chris,
Usually when someone wants a row selector, it's to choose a few rows by clicking a checkbox, then doing something with them. I'm guessing that's what you're looking for?
Martin Giffy D'Souza's [blog post|http://apex-smb.blogspot.com/2009/01/apex-report-with-checkboxes-advanced.html] explains one way to do that which should work for you. I haven't tried, it, but it looks pretty comprehensive.
Good luck,
Stew

Hi unnamed,
Suppose you have an id that identifies your record.
Go to Report definiton, tab report attirbutes.
Select the id of your record.
Create a link to the page you want to go to.
Hope this helps.
If not, I suggest you to create a from with report, and analyze the way the wizard has generated it.
