Read and write data from / to cube in CUSTOM_LOGIC BADI

Here are the details:
BPC displays a set of details - with 5 rows and 5 columns. There are 50 additional rows for the 5 columns which are blank to start with.
User changes a cell. BPC 10 only sends that cell which is changed by the user in CUSTOM_LOGIC and WRITE_BACK BADIs.
I need to get other 5 X 5 cells (other than 1 cell, which is changed and being passed in the BADIs) details to determine all the details and calculate the additional 50 rows. After calculating these values, i need to update the cube so that the BPC report refreshes with the data i have updated.
Whats the best way? What are the funtion modules involved in reading / writing? Are there any best practices to read / write data from cube.
Appreciate your help.

Hi Ravan,
Look at my sample write back badi here: http://scn.sap.com/message/14290977#14290977
At the end of the code I have values updated in ct_data. The contents of ct_data will be automatically written to the cube (you don't need to have special code to write data).

Who will write the SOAP message

when wrting simple Webservice .Who will write the SOAP message?
weather it generate automatically? or we need write?
is there any automatic tools are there to generte the SOAP message?
Please send me a Simple Webservice Example?
Thanks in advance
Raju

Check out http://jax-ws.dev.java.net and look at the samples provided. Netbeans 5.5 beta also makes it very easy to publish a web service. All of the hard work is done for you automatically, to you as a developer it looks just like you are makiing an normal method invocaiton, the framework underneath converts that invocation to/from a soap message.

How to write data from Basic Cube to Transactional Cube

Hi experts,
My problem is the following: I have a Transactional Infocube (IC1) and a basic Infocube (IC2). They have both the same structure. IC2 is loaded with data and other data is keyed in IC1.
I would like to write data from IC2 to IC1 and eliminate data redundancy if there can be some.
Can anyone tell me how I can do that?
Thanks in advance

Hi,
Yes , you have to create a multiplanning area ..
In the planning level , filter the value which you want to copy from basic to transactional cube .
Fields to be changed : Planning area and others as per your need..
Field for condition : if you want to copy data from 2006 then give calyear as field for condition.
Parameter group : give the value 'from' as basic cube 'to' as your transactional cube ..

How long does it take to write data from network analyzer

I am using LabVIEW to control two DC power supplies through GPIB-USB and I have a DAQ-6008 generating 8-bit digital output. I am connecting two DC power supplies and the 8-bit digital signal to my circuit and want to measure s parameters (all S11, S12, S21, S22) and write their magnitude and phase to a .txt file in my laptop. It worked but took about 1.5 minutes to write data (magnitude and phase of four s parameters) for a fixed DAQ output and fixed DC voltage by only sweeping 6 points. Is it a reasonable time? Because eventually I will have more than ten thousand combinations and need to record s parameters for all these combinations and it will take too long. I would like to know which part spends more time or how I can reduce the time to write four s parameters. Thanks a lot.

Hello yll,
-So you mean I should delete some of the controls
in the front panel and make them a fixed value or default in the block
diagram to reduce the front panel controls
What Dennis is saying is that your front panel controls are only read once by your program. The are read at the beginning and the value is passed into the while loop. This is the value that will be used, even if you change the front panel. You can verify this by using highlight execution.
-What does it mean that I am
resetting the instrument each time?
Everytime you call the initialize VI, you send a command for the instrument to reset. This is not necessary, since you want your settings to remain for the entire program. You can reset it when you "first" start using it, but as your program keeps going, you do not need to reset it.
-Do I need the initialize VI and
close VI in every iteration or I should have them out of the loops so
all the instrument are initialized and closed only once throughout the
entire process?
That is exactly what you should do.
-For the network analyzer, when you said I only need the
VIs from initialize.vi to read data.vi (the second one from the end),
do you mean that I can delete the close.vi? and why does it make the
program faster?
You should probably add the close outside the loop, as good practise. I would still put the initialize outside the loop.
I hope this helps.

How to read and write data from Excel to TestStand without using LabVIEW VIs

Hi,
How can I read in columns of data from Excel into a TestStand array and write columns of data to Excel from TestStand without using LabVIEW VIs?
I don't think the Property Loader custom step type in TestStand will work because the data I would like to read in from Excel is in a column that is thousands of rows long and the data has to be in the proper format to use the Property Loader to load in an array from Excel.
Thanks for your help.

That example does not use LabVIEW and it does about 40% of what you need to do by calling Excel through ActiveX. If you don't know how to use Excel through ActiveX then you'll need to brush up on that.

How to write data from 24 bit card DAQ card unscaled

Hello
I have a PXI 4462 Data acquistion card to record data. It is 24 bit card. I have two questions about writing data from this card.
1) When acquiring the analog signal the card changes the analog to digital and when writing it scales back to analog signal. I want to write the analog signal in the digital form. How can i do that.
2) PXI 4462 is a 24 bit card, but there is either 16 bit or 32 bit when writing it. So if i write it in 32 bit a byte is not used. only 3 bytes will be used to write the data and one byte wont have any data in it. It takes space on the hard disk. Is there any way to save this one byte so that I will be able to write just 24 bit data without loosing that one byte which would save me plenty of space.
The sampling rate is usually 96Ks/sec.
Thanks in advance
Regards
Nitin

If you want to write 24 bits instead of 32, then you have to change the hi(x) to 8 bits instead of 16. The lo(x) will stay at 16 so the 8 plus 16 equals 24 bits. Simple arithmetic. You asked how to get rid of the upper 8 bits and if you leave it at 16, then you haven't gotten rid of anything.
Why do you think you have to write to separate files? I said do a write of the 16 bit and then a write of of the 8 bit component. It's just two Write File functions to the same file. You could also bundle them together and do a single write but I think there would be a little additional overhead with that.

Read and write data from content repository .

Hi All,
We are using content repository to store some document and images on web center server .
So we have created/setup a content repository on web center .
Please proivde me some documnet /wiki page to get some idea how can i read and write date in
content repository .
You are most welocme to provide some idea /suggestion .
Thanks,
Arun.

Have you already configured webcenter spaces so it can use content server?
Have you installed the content server seperatly from webcenter or as a part of the webcenter installation?
Check if you have the webcenter spaces component installed in content server because without i don't think it will work...
If you already have configured UCM to work with spaces it's quiet easy.
From your groupspace, open the settings page of your groupspace. Go to the services tab. In the left hand side you can enable the documents services. WHen you have done that, you are able to add the document services taskflows to your pages. Just go to a page in your pagegroup and edit it. Open the resource catalog and you will find some extra taskflows you can add.
If you haven't configured UCM and webcenter to work together, here some steps that will help you:
* Integrating UCM with Spaces
     * They both need to use the same LDAP store.
     * Since there is no LDAP server available, we choose for embedded WLS LDAP.
     * Integrating the ucm into apache
          * Stop UCM
          * In /oracle/product/wls10320/WebCenter/ucm/config/config.cfg, check the SocketHostAddressSecurityFilter to contain 127.0.0.1
          * Add the SocketHostAddressSecurityFilter to /oracle/product/wls10320/WebCenter/ucm/admin/bin/intradoc.cfg
          * Add to /oracle/product/wls10320/WebTier/instances/instance1/config/OHS/ohs1/httpd.conf
               include /oracle/product/wls10320/WebCenter/ucm/data/users/apache22/apache.conf
          * Change the mod_wl_ohs.conf file to
               <IfModule weblogic_module>

How can I do?
Thank you in adv and please, reply soon.

We don't have many samples left for Windows Phone 7 + Azure, the closest one to what you want to do is probably:
Using Local Storage with OData on Windows Phone To Reduce Network Bandwidth
this sample uses the local database feature: 'LINQ to SQL', available to Windows Phone 7.1 and 8.0 Silverlight applications, instead of simple file storage but even if you choose to stick with simple file storage I believe you should be able to adapt the
networking related portions of the sample to your particular application.

How do you configure a WCF-SQL adapter to write data from a SQL2012 "always on" database?

Hi All,
I have a BizTalk environment. I have to write the data from BizTalk to the database which is configured using ALWAYS ON availability group.
I use WCF-SQL adapter to write the data. My question is this setup a supported?

The answer is NO.
Refer: Can
I use a BizTalk WCF-SQL send adapter with a SQL 2012 Always on Database?
A snippet quoted below.
In summary (in order of preference):
Disable AlwaysOn Availability Groups / Mirroring on SQL server if you need to connect to this SQL server which has this enabled
Disable transactions and implement logic to be able to handle duplicates .
Disable transactions and handle the duplicates or lost messages with custom logic (e.g. Send twice and compare and implement error handling). You need to write your own DTC handling this which
is probably very complicated.
Disable transactions and live with risk of duplicates or lost messages without handling duplicates.
Refer: SQL Server AlwaysOn feature does not support MSDTC transactions.

BPC 7.5 will extract data from flat file or directly from cube

Hi,
i have a doubt plz give me a solution.
1) previously our BPC 7.0 team extracted data from BI 7.0 through flat file, but now they have upgraded to BPC 7.5 i want to know whether BPC 7.5 will extract directly from our BW infocube or not.
2) please let me know how data extracted from BPC 7.5.
Thanks and Regards

Hi,
If your import file has duplicate record in it then the Status of your DM package for import ends with warning, where all the records in your file might have got accepted but only one last data rows amoung the duplicate rows might have got submitted to the system.
The duplicate records will be rejected and you can see the list of duplicate records as well in the DM package status report.
Like Nilanjan said you can use Append DM Pacakge to submit all duplicate records aswell into the system. But here the problem is it appends the data in flat file with data available in the system.
Say you have 100 for account1 in the system and you run Append DM Package having values duplicate values for account1 say 100 and 200. So after the Append Package execution you will have 100100200= 400 for account1.
So for Append DM package to work in the same way as import, run clear package before executing the Append package.
Hope this helps,
