Experience with Real-time Data Acquisition (RDA)

Hello all,
We are looking into using RDA functionality to quickly move data from ECC to BW and would like to talk to anyone who has had experience using this feature (did it work well, limitations, what to look out for, etc). Would appreciate if you could share your experiences.
Thanks,

Hi,
Real-Time Data Acquisition BI 2004s
Real-time data acquisition supports tactical decision-making. It also supports operational reporting by allowing you to send data to the delta queue or PSA table in real-time.
You might be having complex reports in your BI System, which helps in making decisions on the basis of data of your transactional system. Sometimes (quarter closure, month end, year ending...) single change in the transactional data can change your decision, and its very important to consider each record of transactional data of the company at the same time in BI system as it gets updated in the transactional system.
Using new functionality of Real-time Data Acquisition (RDA) with the Net Weaver BI 2004s system we can now load transactional data into SAP BI system every single minute. If your business is demanding real-time data in SAP BI, you should start exploring RDA.
The source system for RDA could be SAP System or it could be any non-SAP system. SAP is providing most of the Standard Data Sources as real-time enabled.
The other alternative for RDA is Web Services, even though Web Services are referred for non-SAP systems, but for testing purpose here I am implementing Web Service (RFC) in SAP source system.
Eg will be a production line where business wants information regarding defective products in the real time so that production can be stopped before more defective goods are produced.
In the source system, the BI Service API has at least the version Plug-In-Basis 2005.1 or for 4.6C source systems Plug-In 2004.1 SP10.

BI 7.0 Question on RDA (Real Time Data Acquisition)

Those who have all implemented RDA (real Time Data Acquisition) in BI 7.0, could you please tell me if this is limited to only a few of the extractors or available to all the business content extractors. Reason I ask this question is I read that if you have PI_BASIS 2005.1 then RDA is possible, but when I go into ROOSOURCE table in R/3 I do not see the Real time flag checked for any of the transactional Businees content extractors!!
Also does this mean that we need to set this flag manually and if so is this supported by SAP? please throw in expert your responses...
Ram

Dinesh, thank you...after going throught the posts I am still more confsued and not sure if SAP supports any Business content data sources as RDA Capable yet...also if someone has successfully implemented RDA for any of the following applications please do reply back, thank you...

Problem with Real Time Data Acquisition

Hello,
I tried to built a RDA data flow according to the SAP-Help and this blog (/people/kamaljeet.kharbanda/blog/2006/11/13/real-time-data-acquisition-bi2004s), but I ran into a problem. Everything seems to be fine, but even though the daemon is running no new data is added to the DSO. I'll explain in detail what steps I took and hope someone can pinpoint my error(s).
System is BW4 on SPS 17. My datasource as well as my DSObject are in the same system
1.) Created a transparent table with a timestamp-field for generic delta as a local object.
2.) Created a generic datasource from view/table (used the above table), marked it as realtime-enabled and used timestamp as delta-specific field.
3.) Replicated the metadata for my datasource and activated it.
4.) Created a Data Storage Object with infoobjects corresponding to the table fields
5.) Created a transformation between DataSource and DSO
6.) Created a DTP from Data Source to DSO. The type is realtime-DTP.
7.) Created an InfoPackage for Delta-Initial Load. Update mode: Initialize Delta Process -> Initialization with Data Transfer.
8.) Then I changed my DTP (step 6) to "normal DTP" and executed it. Then activated the data in the DSO. The datasets from the table (which i filled with an ABAP-program) were successfully loaded and activated. So now my DSO contains 5 datasets.
9.) Changed the DTP back to "realtime DTP"
10.) Created an InfoPackage for RDA. Adapter is set to "Realtime extraction from SAP System"
11.) Created a daemon, assigned the IP for RDA and the DTP to the daemon and started it up.
12.) Executed my ABAP program to added 3 datasets to the table which is used as a datasource.
So now in my source table there are 8 datasets, but the daemon won't load them. In my RDA-Monitor (trx rsrda) it shows my daemon, the assigned IP and the assigned DTP (status green). Under the IP there's one yellow request (that should be right according to the help), but unlike the picture in the blog (link see above) there's no request under the DTP.
Job overview (sm37) shows an active batch job and some jobs that are ready (every 10minutes a new batch starts and the old one is closed). the job log shows, that the daemon runs, but loads no data...
i think it might be a problem with the delta extraction somewhere, because the intial load works fine and there are no errors anywhere.
Edit: perhaps my settings in the data source unter tab: extraction are wrong?
Delta process: AIE After Images By Extractor (can't change that)
Direct Access: Allowd
real Time: Real-Time DA Supported
Adapter: realtime data extraction (also tried Access to SAP Data through Service API which seems senseless)
Data Format: Fixed Lenght
Anyone can explain what those fileds mean and which one i should use?

Hi again, another thing i'd like to try is to just active a business content datasource which is realtime-enabled and has the ability to dynamically add some values so that i can test if it works. but i have no idea what business content would be applicable here, any ideas on that perhaps?

Real-time data acquisition for HR datasources

Dear Experts,
I have a couple of questions on real-time data acquisition...
a) Can you tell me if any standard HR datasources support real-time data acquisition?
b) Can we apply real-time data acquisition for generic datasources? If yes, is there any difference in the process compared to working with business content datasources when using real-time data acquisition?
Hope you can provide some answers...as always, points will be awarded for answers that effectively address the questions.
Thanks a bunch.

Hi Karthik,
a)The decision to go for SAP remote cube depends on the volume of data and the frequency of queries. It is advicible not to use the SAP remote cube if the data volume is high and also, the query frequency is high. Which module in HR are yuo implementing? In HR, the data volume is generally high. So, if you go for loading the data from R/3 every 3 hours, you are asfe as long as the loading volumes are less. For example, for implementing Time management, I would not advice frequent loads as it is time consuming process. So, make a decision based on the above mentioned lines. If the data volume is not high, I would prefer the SAP ermote cube as it will reduce managing the loads.
b)I mentioned FM extractor just for the sake of control of data selection. You can even go for view/table extractor.
Hope this helps.
Thanks and Regards

Real time data aquisation(RDA)

hi
if i want use datasource for RDA , its support in r/3 side? so its wont support for flat file?
where can i check the data source will support for RDA or not?
once datasource replicated while creating infopackage need to check check box and dtp need to check RDA

goto SAP system
goto transaction SE16
give ROOSOURCE in Table and execute.
in the next screen give ur DATASOURCE name and execute.
this will give the datsource settings check the realtime field if its checked then ur datasource is real time enabled.
else u can enable it by writing a small program.
goto se38
cerate an executable program with the following code
Tables : ROOSOURCE.
Parameters : P_OLTPSR LIKE ROOSOURCE-OLTPSOURCE.
UPDATE ROOSOURCE set REALTIME = 'X'
WHERE OLPTSOURCE = P_OLTPSR
and OBJVERS = 'A'.
When u execute this program it asks for datasource name , give ur datasource name and execute. it will real time enabled.
u can again check it in SE16.
hope this helps.

Issue with Real-Time data acquisition

Hello,
I'm using RDA to extract a non-standard transparent table (Z*) from ECC to BI. When I launch my deamon, my infopackage and my DTP become yellow only 2/3 seconds and green just after, and no data are coming from ECC.
If I check the deamon log I could see following lines :
Job started
Step 001 started (program RSCRT_RDA_DEMON, variant &0000000001977, user ID XXXXXX)
InfoPackage ZPAK_4J6KVMAKPPWI3FYUYAWVLYVWL for daemon 01 is locked

Data package 000001 opened, status set (4 -> 2)
The current application triggered a termination with a short dump.
Upload finished for InfoPackage ZPAK_4J6KVMAKPPWI3FYUYAWVLYVWL for daemon 01
Setting status of InfoPackage ZPAK_4J6KVMAKPPWI3FYUYAWVLYVWL
Status set (3 -> 2)
A short dump is triggered in ECC, MESSAGE_TYPE_X in FM RSC3_DEMON_UPL. Why ???
I have done another extractor (on a HR infotype) and It works fine.
Thanks for your help,

First tip is to not configure the daq task and close the task on every iteration of the while loop. Configure the task before the loop starts and close it after the loop. Only stop and configure the task in the event that any of the configuration data changes.

Display real time data on a plot in a sub VI and main VI

I am building a program to measure and plot real time data. Program has several steps so I build few Sub VIs to make it simple. My problem is I am plotting real time data in my SUB VI(it works fine), but in my main program when I try to get the same plot its not real time data plot. Plots appear at the end of the program. All tips and help would be greatly appreciated. Thanks
I have attached my main VI and Sub VI

LabVIEW program is based on DATA FLOW, now, until the subVI will finish execution (while loop will be stopped), the execution in Main VI will not proceed any further.
If you can pass the reference of 'XY Graph' inside the subVI, you'll be able to update the plot (placed on MAIN VI) from within subVI.
Find attached example for your reference.

How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

I use LabView student Express 7 on a Windows XP system.
Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
Note on license
It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
Problem synopsis:
The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
BEXUS[h][m][s]BEXUS[h][m][s]
[Raw binary data, 7channels*8sub-channels*8bits]
What the groundstation is doing right now:
Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
What I need to change in less than 24 hours:
- Add a "package" counter
- Add a display of the clock data (RTC)
How I planned to implement the changes:
-RTC display:
The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
- Package counter:
Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
Thanks!
PS: even if you are to late (after 25) post anyway!
Why:
-I can learn from it
-the launch might be delayed due to weather conditions
-others might find it amusing!
Thanks again!

BexusII_groundstation.vi ‏46 KB

I have a valid example data file attached to this thread.
If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
The file was saved using a straight save to file VI.
The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
I will monitor this
thread during and after flight to see if anyone can make it in time!
Thanks for the great effort!!

Error "cannot load request real time data targets" for new cube in BI 7.

Hi All,
WE have recently upgarded our SCM system from 4.1 to SCM 7.0 which incorporated BI 7.0.
I am using BI 7.0 for first time and ahve the following issue:
I ceated a new infocube and data source of flat file and succesfully created transformation, and Data Transfer Process. Everything looked fine. I added flat file and checked preview and could see data. Now when I start job to load data in infocube the follwing error is shown "cannot load request real time data targets".
I checked cube type in setting in infcune is shows as Standard. When I doube clicked on error the following message showed up
You are trying to load data into a real-time InfoCube using a DTP.
This is only possible if the correct load settings have been defined for the InfoCube.
Procedure
In the object tree of the Data Warehousing Workbench, call Load Behavior of Real-Time InfoCube from the context menu of the InfoCube. Switch load behavior to Transactional InfoCube can be loaded; planning not allowed.
I did not understand what it is meant and how to set changes. Can someone advice and follow me through.
Thanks
KV

Hi Kverma,
Real-time InfoCubes can be filled with data using two different methods: using the transaction for entering planning data, and using BI staging, whereby planning data cannot be loaded simultaneously. With Real time cube you can select the method you want to use for update as
Real Time data Target can be loaded With Data; Planning not allowed &
Real Time data Target can be Planned; Data loading not allowed
You can change this behaviour by right clicking on cube and selecting Change real time load behaviour and select first option. You will be able to load the data then
