How to extract the historical data from R/3

hi
I am extracting data from R/3 through LO Extraction. client asked me to enhance the data source by adding field. i have enhanced the field and wrote exit to populate the data for that field.
how to extract the historical data into BI for the enhanced field. already delta load is running in BI.
regards

Hi Satish,
As per SAP Standard also the best way is to delete whole data from the cube and then load the data from set up tables as you have enhanced the data source.
After data source enhancement it is supported to load normally because you don't get any historical data for that field.
Best way is to take down time from the users, normally we do in weekends/non-business hours.
Then fill the set-up tables; if the data is of huge volume you can adopt parallel mechanism like:
1. Load set-up tables by yearly basis as a background job.
2. Load set-up tables by yearly basis with posting periods from jan 1st to 31st dec of any year basis as a background job.
This can make your self easier and faster for load of set-up tables. After filling up set-up tables. You can unlock all users as there is no worries of postings.
Then after you can load all the data into BI first into PSA and then into Cube.

  • How to extract audit log data from every document library in site collection using powershell?

    Hi All,
    I have n number of document library in one site collection,
    My query is- How to extract audit log data from every document library in a site collection using powershell?
    Please give solution as soon as possible?

    Hi inguru,
    For SharePoint audit log data, These data combine together in site collection. So there is no easy way to extract audit log data for document library.
    As a workaround, you can export the site collection audit log data to a CSV file using PowerShell Command, then you can filter the document library audit log data in Excel.

  • How to get the complete data from Webdynpro using a RFC

    hi guys,
    A form is created in the webdynpro, when that pdf form is called the user have to provide the key field ie the employee number in the form and then when he press the 'go' button a rfc is called and it gives all the details of the employee in the form. Then the user have to input some fields in the form and he have press the submit button. My problem is here, when the user is going to press the submit button that form will be converted to a stream (binary) of data and it is sent to one of the import parameter used in the RFC.
    I have created a RFC and created a import parameter of data type XSTRING, since i want to see what exactly R3 is receiving from web dynpro i am writing this contant in the sever as a text file. When i saw that text file i cant see the complete data.
    And when i searched in R3 the capacity of xstring is 1024 CHAR, so i dont know how to capture the entire data from webdynpro into my R3.
    I give the code what i worte please tell me am i missing anything in my code, or is there any data type which can hold more than 500kb of data which is coming from webdynpro.

    You have to convert your long string to a table of shorter strings.
    There may be other ways, but one possibility is to use a loop to process you string.
    while (there is something left)
       put the next e.g. 1024 characters in a new row of your table
    endwhile
    If you need to reconstruct your string from the table, don't use simple concatenation since it will remove blanks at the end of lines. Believe me (from experience) sooner or later this will happen.
    Instead you need to either set the subsections of your long string, or insert from the end of your table and keep shifting the contents (probably less efficient) right

  • How to delete the duplicate data  from PSA Table

    Dear All,
    How to delete the duplicate data  from PSA Table, I have the purchase cube and I am getting the data from Item data source.
    In PSA table, I found the some cancellation records for that particular records quantity  would be negative for the same record value would be positive.
    Due to this reason the quantity is updated to target but the values would summarized and got  the summarized value  of all normal and cancellation .
    Please let me know the solution how to delete the data while updating to the target.
    Thanks
    Regards,
    Sai

    Hi,
    in deleting the records in PSA table difficult and how many you will the delete.
    you can achieve the different ways.
    1. creating the DSO maintain the some key fields it will overwrite the based on key fields.
    2. you can write the ABAP logic deleting the duplicate records at info package level check with the your ABAPer.
    3.you can restrict the cancellation records at query level.

  • Open hub Services - How to extract the master data related to a object ?

    Hi Gurus,
    I am implementing OpenHub services for our project, it's on BW 3.5, I have the list of required fields with which I am creating an InfoSpoke. Now I am stuck in some the info objects which are having master data associated with it.
    Example : Business partner(BP) data, when I map the 0BP infobjects in infospoke it's extracting the BP ID (ex: CT065316,CT068638 etc) in flat file but I want the BP name, address & telephone number as well, which are coming from master data table. But I am able to map only 0BP infobjects as a part of ODS/Cube.
    Can any one tell me how to get the master data extracted in the flat file with associated info object???
    Answers will be highly appreciated.

    Edited by: Kironmoy Banerjee on Oct 1, 2009 3:34 PM

    Hi Kironmay
    Please follow the below mentioned procedure to create a transformation. This is applicable for BW 3.5 as well.
    - Enter your infospoke in the edit mode.
    - On the Transformation tab set the indicator for the Infospoke with Transformation with BADI so that the infospoke is activated.
    - This will take you to the Addin implementation/BADI builder.
    - Enter the short text/description for the implementation. The implementation name is always the same as the technical name of the infospoke
    - The implementation of the BADI is always filter dependant.
    - In the properties tab of the infospoke enter your infospoke under the Filter specifications.
    If you do not specify an InfoSpoke under Filter Specifications, then this implementation is valid for all InfoSpokes. This means that this is called up for all InfoSpokes during the extraction.
    - Activate your class
    - From your interface tab page, double click on the Transofrm Method and you will arrive in the class builder page
    - Here you can enter the code
    - To do a look up of the master data you have to write a code similar to the one I've given below. This is just an example for looking up material master.
    IF FLT_VAL = 'Your infospoke'.
        T_DATA_IN[] = I_T_DATA_IN[].
    Select zstd_cost from /bi0/pmaterial into table T_return
    For all entries in T_DATA_IN
    WHERE material = T_DATA_IN-material.
    ...Continue with your code.
    Append output from T_return to your output E_T_DATA_OUT
    - Activate your method. Return to the BAdI builder. Return to your InfoSpoke.
    I hope this helps.
    Thanks.

  • How to extract the red layer from BayerRG8 file with VBAI?

    Dear readers,
    We're currentely trying to build a inspection program using a CVS and two cameras.
    A first question to help us: How can we extract the red layer from a Bayer RG8 image?
    To illustrate a lit bit more: lets take a picture of chilis and tomatoes plants. We would like to extract the red color of the picture to know where the vegetable are and if they are eatable.
    So, in a first time, we just want to see the red layer of the picture.
    On a second step, we would like to extract the poistion of the red areas and rank them according to intensities and store all the relevant data in a .txt file.
    Thank in advance for the time you will spend on that topic.
    Regards

    Maybe including a picture with the info you want would help. It sounds like you could use a detect object step (which works with color images), and you could get the position of all red objects. I would also recommend using the Hue plane instead of the Red plane to look for color since this is more robust to lighting changes. Once you have the bounding box for each red object, you can create a programmatic ROI around it and use the Measure Color step to get detailed color information about your reb objects. Here's a sample inspection that uses colored candy to give you an example of what I'm suggesting. Let us know if more specifically what you are looking for if this doesn't help. The example is in VBAI 2012. Let us know what version of VBAI you are using because this may affect what functionality you can use.
    Thanks,
    Brad

  • How to get the forecast data from SCM into BW

    Hello,
    Is there a table or Function module in SCM F&R  that can be used  to transfer the forecast data from SCM F&R into BW? I dont see any Business content datasources that has the forecast data.
    I would like to get the future forecast data. For ex, if there is a forecast for a material and Site for the next 52 weeks, I would like to retrieve
    the same from SCM. I dont see any business content. The closest would be 0FRE_ANA_WEEKLY_1. But it has only the past data, not the future data.
    Thanks,
    SBS.

    Hi,
    You would follow the same process as you would for getting data from a R3 system to BW, i.e generate datsources on the APO side and then set the extraction to flow from APO to BW. On the BW side, you'll need a source system for the APO, replicate datsources, set up update and transfer rules in the infosource and then load data to the data targets.

  • How to recover the autocomplete data from a Time Machine backup?

    How to recover the Safari 5.1.7 autocomplete data from a Time Machine backup on Mac OS X 10.6.8 (Snow Leopard)?
    To solve other issues (Safari crashing sometimes when saving web pages), I selected:
    Safari - Empty Cache
    Safari - Reset Safari - Selected ALL - Reset
    I could later on recover some Safari autofill data restoring
    HD/Users/~/Library/Cookies/Cookies.plist
    HD/Users/~/Library/Safari/Form Values
    HD/Users/~/Library/Safari/History.plist
    but other autocomplete data is missing, including the one when filling web form search fields in web pages, for instance, and also some username and password login data on some web sites.
    How to restore all such data from the Time Machine Backup?
    Thanks!

    I also recovered:
    HD//Users/~/Library/Keychains/login.keychain
    What else should I recover?

  • How to extract 64 bit data from imaq image using IMAQ Extract VI

    I have LV 8.5.1, Vision 8.5 and need to extract 64 bit data from a 64 bit image and I get the "invalid image" error while using the IMAQ Extract VI.  What version of Vision do I need to allow me to do this? 
    Currently, the work-around I have...
    1) convert the image to 32bit
    2) use the ROI tools I to get the rectangle data I need
    3) then go back to the original image and the convert the image to a 64 bit array
    4) take the rectangle data to extract the data needed out of the 64 bit array data.
    klunky but it works.  I would think that the IMAQ Extract tool should allow me to extract the 64 bit data but it doesnt... forces me to 32 bit.
    suggestions?

    awesome, that does work. 
    Attached DLL slightly corrected and should be OK also "in place" when Dst is not connected like original IMAQ function. Hopefully it works properly now. By the way all IMAQ types are supported, not only U64.

  • How to see the historic data of CAT2

    Dear All,
    I have a question related to CATS.
    Through which table I can get the historical data of an employee which is stored in CAT2 transaction. I tried through CATSDB but not able to get the number of working hours as stored in CAT2.
    I clied on a field of CAT2 and checked the technical details. there I found the table name CATD but when I run SE11 and enter this table name, it display it as a sturcture not as a table.
    Please provide your help in this regard.
    Regards,
    -Neha

    Maximum NUmber of Columns allowed is 1023. So if there are more data than that, I am afraid there is no way to see them all in one screen.
    the better thing to do is to use the Settings>Format List>Choose fields option from the selection screen of SE16 to just choose the fields which you want in the output.
    It is highly unlikely that you are using all the 100 fields so you can very well hide a few of them with no impact on your output.
    As someone else has suggested using a report such as CATSXT_DA will defintiely be a much more useful way of viewing all relevant fields from CATSDB.

  • How to extract the signal out from the waveform by my designated power level?

    Dear all,
         How can  I extract the signal from the waveform accroding to the power level? I read the Trigger&Gate.vi, but this vi extract signal according to the duration time. I want to extract signal according to power level.
         As shown in the following figures, the signal I want to process is between 130000 to 140000, if I zoom in, I can see the the useful signal is between 135400 to 138200. The question is how to extract the signal in the zone?  
        I tried the sub_NoiseEst_And_Chop_Shell.vi in the Packet_based_link example too, but this subvi seemed to be a little slow. Can anybody give me better advice? Thanks in advance!
    Solved!
    Go to Solution.

    I was working on something similar but haven't had time to fully develop it.
    My idea was to use an envelope detector (low pass filter) and then use an energy detection VI on the envelope.
    Here's where I left off
