DataGrid - Excel functionalities

Hello all,
We are trying to develop excel basic functionalities in Flex.
first of all I just want to know if someone heard about code examples that implement basic excel functions in flex advanced/datagrid , such as : drag and drop (but not to other datagrid, to the same data grid) , drag and fill (i.e select row and drag it to other row in the same grid, and it will copy the drag row values  to the one that we drop on) etc .
actually I aware that there aer a lot of standard functions that allow to drag & drop, but the main problem that we have is to "drag & fill", or copy multiple cells to other cells (like excel) in the same grid.
I'll be glad to get any help/direction to solve those problems, Thanks.

Hi,
I am attaching one sample application on Grid drag and drop. Please go through it and let me know if it can helps your requirements. Try to drag and drop any row in the grid then you will come to know how extra row gets created. Copy the file excelGrid.mxml and folder terra into your project src folder. Then run this application.

  • Standard Excel-Functionalities not usable when using BexAnaylzer

    Hi Experts,
    I am using BexAnalyzer as a reporting tool. Query Designer is on 3.5.
    I have safed a few queries within a workbook.
    Next step is to combine results of different queries by using standard excel functionalities (SUM, etc.) to create a new report. This works more or less fine.
    Here is my problem: When I refresh the queries, the excel based report is not automatically updated.
    The happens because standard excel functionalities dont take new numbers in updated queries into consideration.
    Any idea?

  • Issue sorting dates in export to excel

    After exporting to excel, the end-user wants to sort on a date characteristic (posting date), using excel functionalities. This gives an incorrect result:
    01.01.2006
    01.01.2007
    01.02.2006
    01.02.2007
    If we sort on a time characteristic (calendar day), the list is sorted correctly.
    If we run the report via the BEx and then sort (using excel functionalities), it is also correct :
    01.01.2006
    01.02.2006
    01.01.2007
    01.02.2007
    How can we enable the correct sort?
    Thanks for your help!

    Dear Karthikeyan,
    I was also facing the same issue, and the reason was the diifferrence in the protocol of the J2EE WAS and that of Diapatcher.
    check whether J2EE WAS and that of Diapatcher are both on http or on https. If they both are not same, that's the issue.
    Hope it helps!!

  • BSP Excel Web Coomponent

    Good Morning Everybody;
    As you know BSP provides a built-in Excel Web Component.to provide Data Entry for the users extending all Excel functionalities. The excel web componennt in BSP is provided by the vendor "Microsoft Web Components" Ver. 11.0.0.6555.
    The problem we faced, This exel web component in BSP is lack of "freezing columns" as the ordinary excel we have.
    Any suggestion to handle this issue??
    With Regards

    this is not a BSP issue. its Microsoft OfficeWebComponent issue and you may find some answer if you search in MSDN or microsoft forums. As far as i know Excel web component doesnt offer column freezing.

  • Analyzer Security for SAP BPC 7.5 SP6

    Hi ,
    We have recently installed Analyzer add-in on our excel for Adhoc reporting on SAP BPC 7.5 SP6
    But analyzer is not considering the data security restricted for specific region.
    For eg: If a planner is assinged to EUROPE planning role and when he creates reports using analyzer he is able to see the data for all the regions(NA,EMEA,ASIAPAC).
    Is there anyway we can restrict the planners to see the data relevant to their role in Analyzer.
    we had a look at security in Admin client. Is there anyway to handle this.Thanks much.
    Regards,
    Sanjeev

    Hi,
    You can use Bex analyzer for detailed reporting. Both the analyzer and BPC reports can be connected using the normal excel functionalities (in a single excel workbook) so that BPC CV selection will be fed into Bex as variables and relevant data records are displayed in Bex reports. Performance of Bex analyzer is slow. That is one of the main reason it was replaced with BO reporting tools.
    If you are using BPC 7.5NW, then there is a standard functionality called DRILL THROUGH. Using this functionality you can drill down to detailed data in BW.
    Bex and BPC have different authorizations. You can maintain authorizations in BW roles and try to manually replicate same authorizations in BPC (there is also a how-to doc on automating this synchronization).

  • Changing the column order in Table UI

    Hi I researched a lot and since my ALV didnt work Im back to Table ui . I implemented sorting and Export to Excel functionalities in table ui element just like in ALV. But now The client also wants to have the ability to change the order of columns of the table (like in ALV under settings link).
    Could someone just direct me to a proper tutorial or something where i can see the tutorial and make it please.
    Thanks.

    Ok.Just one thing. When we right click on the table on screen then it opens up a user settings where the user can adjust user-specific settings.
    Im just planning to do this. Ill give them this settings with a button on the top of the table. So basically even if i know that the user settings of the table can be opened by right clicking that .But it'll be great if I can put that action of opening up the user settings popup in a button onaction event and placing that button on top of the table.

  • Parent/child issue

    Hello, I need to create a report in which if the user selects a specific parent, it should only allow to select the children under that parent. so e.g. Under time dimension, There is year and Quarter property. so when a user enters 2008 as the year, it should only allow 2008.q1, 2008.q2 etc under Quarter. how do i make this happen?
    Thanks.

    Hi,
    You can use the excel functionalities combined with BPC features. If you want to display the dependants, you can use BAS. If the users are entering the year, then you can use something like YEAR = 2008 and LEVEL = QUARTER, etc.
    Please take a look at the below link from help.sap:

  • Advantages and Disadvantages of BEx Analyzer

    Dear All,

    Hello Ratish,
      The advantages and disadvantages are primarily based on the light weight client and heavy client.
    Excel -
    1. It is heavy weight and needs a client installation
    2. Analysis is easier , as excel functionalities can be used over BI data
    3. People who know excel will like this
    Web-
      1. It is light weight and no installation needed at the client as browser will be available
      2. Can not analyze the data from the report ( you need copy to excel)
    In simple analysts and expert users like excel.
    Users who just view the report and no more analysis will be happy with web.

  • Custom Aggregates in BI (Reporting)

    Hello EveryBody
    Currently, we have Oracle Sales Analyzer (OSA) as Our tool for the Sales Reporting, we are going to replace this tool by BI 7.0.
    Currently, the final users can create customs aggregate in the OSA GUI, this means, that they can create a new item in the dimension as the sum of two other item of the same dimension. For Example, in the Dimension Product, we have the SKU1 and the SKU2 the user can create a new item call SKU3. And this new SKU3 (SKU1 +  SUK2) is avaliable to include in all the different reports where we have the dimension Product.
    I would like to know if we can have this functionallity in BI 7.0? and if this functionality depends of the final users or the IT Team?
    Thank in advance for your help.

    Hi,
    As per the definition of BI we can only read from it. I mean be it any datawarehouse, it will have only read only property.
    The analysts will use the Bex Analyzer to analyze any data in BI and he has the freedom to do anything with the data in the Analyzer using common Excel functionalities, like adding 2 key figures that you have just mentioned here. If he wants to circulate his analysis, he can circulate it to his colleagues using Broadcast or Publish in BI
    You will have to read through these functionalities and see if it matches your requirement.
    And if the analyst is doing some kind of planning activity by adding key figures, then BI has its planning capabilities where in it allows you to write into BI as well.
    Integrated Planning in BI itself is a different domain.
    Hope this gives you an idea of how diverse SAP BI can be !
    Assign points if helpful
    Thanks

  • Convert to formula

    Hello all
    Ib bex Analyzer, there is the option of "Convert to Formula". what is the main options and advanteges of this appliction?
    B.R
    Yuval

    Hi,
    Im not that pretty sure about the usage of this.
    But what I have observed is that:
    1) 'Convert to Formula' converts your input ready layouts into a normal Excel layout.
    2)The input readiness is lost once you convert it into formula.
    3)All the compounded characteristcs are removed from the layout.
    4) If a Key Figures of type % is initially displayed as 70%, then after converting it to Formula, it displays as 70.
    For Eg: If keyfigures for Amounts were displayed as 200INR, $100 initially, then once you click on Convert to Formula, the KFs are displayed now as 200,100 and you can do the normal Excel functionalities now like Sum, Min, Max, Average, Count ,etc.
    The result rows will be displayed now irrespective of the currencies / units in rows. ie: 200, 100 , the sum is displayed as 300.

  • Implementing a file server and backup solution

    Hi there - Looking for sage advice from the experts! Here's my dilemma:
    I have a 1st gen Intel iMac, and I recently picked up the 13-inch aluminum MacBook. Both have 250 Gb drives. I have a fair amount of media and software using all but 9 gigs of space on the iMac. One more Final Cut project should eat the majority of that:-)
    Before I start moving media over to the MacBook and run into the same space issues, I'd like to come up with a storage and back up solution that does the following:
    1. Provides one centralized location for all media (music, photos, video files)
    2. Keep back ups of centralized location AND backups of both iMac and MacBook--I don't want to lose any work in progress.
    I'd love to hear how others manage this problem. Can a Time Machine solve the problem? Am I looking at a RAID solution?
    Thanks for your help!!

    Hi,
    In a case where the same workbook is saved locally and on the application server and this error happens, what is the decisive factor? Meaning why does this happen for some workbooks and not for others? Is it a question of size, number of queries, other?
    Do embedded excel functionalities and update links also interfere?
    Many thanks in advance,
    Fabrice.

  • How to Save Data from DataGrid to Excel Sheet?

    Hi All,
    I am trying to use Adobe Flex 3.0 for making web pages.
    I want to save the data from DataGrid and Advanced DataGrid of Adobe Flex 3.0 to Excel Sheet file. I am trying Flex Help, but didn't find answer for it.
    In the application there is a button for 'save' by pressing which the 'Save As' window should appear.
    And giving the path to the '.xls' file, the data from DataGrid should be saved on that location in .xls format.
    This is my requirement.
    If anybody knows how to do this please help.
    Thank You,
    Sharad

    Hi
    Using document.applet.saveAsCSVFile(); code you can not get data in proper format.
    For  one of my application i have stored the data from Grid to excel.
    But i am not sure about Adobe Flex 3.0, my code will work or not.
    Also you need to make the "Initialize and Script Activex Control Not marked as Safe" as enabled in your IE.
    You can share ur email. So that i can send the code. Here I am not able to paste the code.
    Thanks
