  • Variable Substitution and Dynamic Configuration

    Hi All,
    In Variable Substitution , the name that should be given the the receiver payload should be part of the Source Payload unlike the Dynamic Configuration wherein the file name can be generated dynamically during mapping.
    I have the following questions
    1.Dont we need to write the UDF for the Variable substitution?
    2.Cant we do the Dynamic configuration without writing UDF?If so then how?
    3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
    Thanks in advance

    Hi Shwetha,
    1.Dont we need to write the UDF for the Variable substitution?
    No. Here we are accessing the contents of the payload to the target. So no UDF required.
    2.Cant we do the Dynamic configuration without writing UDF?If so then how?
    Yes and No.
    Because we can set only few Dynamic configuration  values without UDF.
    If both source and target are File, then check ASMA on both sender and receiver. Then u can get the source directory name and source file name for target also without any UDF.Also some other parameters.
    3.In Dynamic Configuration the file name is generated dynamically.But where does the file name come from if it is not the part of the source payload?
    The file name comes along with the source in the payload as a attribute in header. U can view this in SXMB_MONI, and Dynamic Configuration.
    In Dynamic Configuration the file name is generated dynamically.
    No the file name is taken as it is from the source, if u want to change dynamically that u have to do in a UDF.
    I hope this will clear all doubts,
    If nt pl post

  • What´s the difference btwn c/a and e/a?

    PLease diference between C/a and E/a in a model of an ipad, because i do not know which one to buy.

    I am guessing the last characters of the model number end with C/A or E/A. The US versions end with LL/A.  According to the site in the link below, C/A would be Canada and E/A would be Mexico. Just guessing.

  • What is the difference between live auction and bid invitation

    hi friends
    what is the difference between live auction and bid invitation
    thanks
    regards
    vinaykrishna

    Source SAP.    
    BI including Price and non-price variables but LAC Bidding is based on price only.
    BI - Longer response time for Bidders (from days to week) but Bidding short bidding windows (Hours).
    BI - Bidders sees no information on competitors' bid but in LAC Rank,Best Bid , and next bid can be displayed on real time
    BI-Well suited for large variety of goods and services , including ram waterials, services and projects but LAC More suited for commodities or goods and services with standard attributes that vary only slightly from supplier to supplier.
    BI -Sourcing is based on value propositions (.eg. High Quality ,fast deliveries) rather than price but LAC market dynamics of auctions work best when buyer/seller relationship is loosele- coupled.

  • What is the difference between message type and element

    hi,
    When we create a new variable in BPEL we get the option to create 'simple', 'message type', 'element'
    I would like to know what is the difference between message type and element.
    thanks
    Yatan

    A message is part of the service and is usually assigned to one of the operations in the wsdl. For example getPhoneNumer() operation may have an input message of personInput and output of phoneNum. These messages would have a type...maybe of string or decimal or a complex type with multiple values.
    An element is typically a complex type that could be defined in an xsd file.
    When you create a variable in the bpel, you can declare it as a message or a simple type or an element. As I understand it, the simple types are pre-defined in the schema namespace such as string, decimal, date, etc.
    The elements are defined in the xsd files or wsdls and can be a combination of strings, dates, etc or other stuff as well.
    The messages are defined in the wsdl as part of the input/output but they are typically assigned a type just like other variables you create.

  • What is the difference between sy-uline and uline in sapscripts ?

    hi guys,
    what is the difference bt sy-uline and uline in sap scripts ?
    this is an interview question ?
    also how can we draw a line without using above ?

    Hi ,
    sy-uline is a system field.
    No-difference.  Except that uline is used outside
    the Write Statement
    TO draw a line.
    /: POSITION [XORIGIN] [YORIGIN] [WINDOW] [PAGE]
    OR
    Draw a horizontal line by setting the HEIGHT in a BOX command to 0. Draw a vertical line by setting WIDTH to 0.
    /: BOX FRAME 10 TW WIDTH 0 TW HEIGHT '10' CM
    Vertical line 10 CM long
    /: BOX FRAME 10 TW WIDTH '10' CM HEIGHT 0 TW
    Horizontal line 10 CM long
    ALSO
    You can draw a line by setting the Height or Weidth to 0
    and add a frame. E.g. a horizontal line:
    /: SIZE HEIGHT '0' MM WIDTH '200' MM
    /: BOX FRAME 10 TW XPOS '11.21' MM YPOS '14.81' MM INTENSITY 100

  • What is the difference between Topic Keywords and Index File Keywords?

    What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
    RH9.0.2.271
    I'm using Webhelp

    Hi there
    When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
    Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
    As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
    <meta name="MS-HKWD" content="BOFFO" />
    When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
    Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
    Hopefully this helps... Rick

  • What is the difference between Video-out and mirroring?

    What is the difference between Video-out and mirroring? I can't get iPhone 4 video to work on my TV screen
    I have just bought an MD098ZM/A (Apple 30-pin Digital AV Adapter). I am struggling to get it to show a picture on my TV. I know I'm doing something right because the audio is coming out of my TV speakers but no picture on the TV screen.
    I have used the same HDMI channel (on the TV side) with the same cable and my thunderbolt port (MacBook Air) without any trouble - and on the same app (BBC iPlayer download then full-screen mode).
    Now I note that the packaging for the MD098ZM/A says video-out on iPhone 4 but mirroring only on iPhone 4S. I only have an iPhone 4 (not the 4S). Now if the lack of iPhone 4 support for mirroring means that I can't play video material out to my TV, then in what sense is there any video-out capability at all?
    There is only safety and warranty paperwork in the Apple adapter packaging - no help information. And I haven't found further guidance online either.
    I do note somewhere online that it suggests that basic non-mirroring video-out (for this adapter) only works with some external TV sets. Any way of finding out which? I'm using a Sanyo CE32LD90-B LCD TV if it helps.
    So far not doing very well.

    Now found these but have had to give up on this adapter!

  • What is the difference between jsp :include and server side include

    what is the difference between jsp :include and server side include(request dispatcher include method)????
    i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
    Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
    do suggest if u hav ny other diff in this context...

    The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
    If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
    Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

  • What is the difference between Session timeout and Short Session timeout Under Excel Service Application -- session management?

    Under Excel Service Application --> session management; what is the difference between Session timeout and Short Session timeout?

    Any call made from the API will automatically be set to the “Session Timeout” period, no matter
    what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

  • What is the difference between document class and normal class

    Hi,
    Please let me know what is the difference between document class and normal class.
    And I have no idea which class should call as document class or call as an object.
    Thanks
    -Actionscript Developer

    the document class is invoked immediately when your swf opens.  the document class must subclass the sprite or movieclip class.
    all other classes are invoked explicitly with code and need not subclass any other class.
