What is the difference between delivery date and actual goods issue date?

Hi ,
Can you please tell me the difference between Delivery date and Actual goods issue date ?
Delivery data can be be greater than goods issue date?
Thanks,
Ajay

Hi Ajay,
              Delivery date means its the original date on which the delivery should be done.Actual goods Issue date is the date on which goods to be delivered according to the purchase order.There can be delay in the delivery so we maintain 2 objects.
Yes delivery date can be greater than Goods Issue date.
Hope this clears

  • The difference between system restore and last good known configuration

    hi,
    what is the difference between system restore  and last good known configuration.
    in which situation you use system restore ,and in which situation you use last good known configuration.
    very short answer wil be enough.
    thanks
    johan
    h.david

    Last Known Good Configuration deals only with Starting Windows eg. a bad registry or incorrect driver is preventing Windows to start.It recovers the registry settings of HKEY_LOCAL_MACHINE\System\CurrentControlSet
    While System Restore uses restore points to return your system files and settings to an earlier point in time without affecting personal files. Restore points are created automatically every week, and just before significant system events, such as the installation
    of a program or device driver. You can also create a restore point manually.You can undone system restore but there is no such option in Last Known Good Configuration.
    Last Known Good Configuration is disabled in Windows 8 or,Windows 8.1 by default.
    Try using Last Known Good Configuration if you can't start Windows, but it started correctly the last time you turned on the computer.
    Try using System Restore to return the system to an earlier point in time when things worked correctly.

  • What is the difference between Category Mgmt and Spend Analysis?

    Hi Friends
    What is the difference between Category Mgmt and Spend Analysis?
    Regards
    Chinna Krishna

    Hi Chinna
    Here are my two cents on this questions
    1. Catagory Management : It pertains to all sourcing activities that a purchasing group does for a specific catagory of items ( say tyres, bearings, etc. in automobile industry scenario OR steel sheets, electric motor, etc. in consumer durables industry scenario) in order to meet companies strategic goals like cost, quality, delivery and new product introduction. It also involves the strategic sourcing piece for that category. Typically it can include following activities for a category which is being managed
    - Identifying current and future business & technical requirements
    - Constant vigilence and analysis of supply market for that category ( and also identifying new sources)
    - Lauching various projects within category focussed on cost reduction, quality improvement, delivery improvement. This may include some of activities like supplier analysis. RFx, Reverse auctions, contract negotiation, etc.
    - Monitoring the category specific supplier performance
    Category Management team typically consists of cross functional team and it is iterative process (continuous improvement).
    Category Management in covered to some extent in E-Sourcing application and its analysis is covered in Spend Analytics application. Fully blown category management is on road map of SAP but none of the current functionalities addresses it fully.
    2. Spend Analysis: This involves analysis of the spend at highest level of organization. To improve the data quality, it typically involves spend data standardization & enrichment, supplier normalization and spend categorization. Once you have clean data, one can slice and dice the data to gain insight into the spend and identify opportunities for launching the various initiatives focussed on cost, quality and delivery.
    SAP Spend Analytics application covers this spend analysis capability.
    Its a long answer and hope it helps you.

  • 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's the difference between "local reminder" and "push notification?

    A friend has been bugging me about this, does anyone know what's the difference between "local reminder" and "push notification" in an iPhone app?

    In a nutshell, local notifications are popup notifications from applications on your phone, based on data that's already on the local phone.  Push notifications are popup notifications you get when new info (like an email, tweet, or update from something like Facebook) gets pushed to your device from a server.

    1.What is Format Payments (SEPA Structured)?

    2.What is Format Payments (SEPA Unstructured)?

    The customer is checking Note.791226.1.
    However, he says that he cannot understand these two differences.
    Please teach me.
    Thanks.

    From the European Payments Council website:
    Remittance information: structure the unstructured
    The SEPA Credit Transfer Scheme permits the end-to-end carrying of remittance data on a structured or unstructured basis appropriate to the nature of the payment (the remittance information usually contains details of the contract underlying the transaction such as an invoice number, for example). The length of the remittance information in the SCT Scheme is fixed at a standard length of 140 characters and banks are obliged to pass on the full remittance information.
    The EPC supports a proposal developed by the European Association of Corporate Treasurers (EACT), which allows companies to agree on a structure for the remittance information. The EACT suggestion on how to structure the "unstructured" remittance fields allows companies exchanging a credit transfer to agree, among other, on information to be transmitted in a specific manner. Banks will carry remittance information structured in such an agreed way unaltered throughout the process chain.

  • What is the difference between smart forms and scripts.?

    what is the difference between smart forms and scripts.?

    Differences between Smartforms and SAPscript
    a) Multiple page formats are possible in smartforms which is not the case in SAPScripts
    b) It is possible to have a smartform without a main window .
    c) Routines can be written in smartforms tool.
    d) Smartforms generates a function module when activated.
    e) Smartforms can create web enable forms like XML
    f) smartforms itself contine subroutine pools need not to main separetly like in case of scripts
    Request you to refer the following links
    www.sap-img.com/smartforms/smartform-sapscripts.htm
    www.erpgenie.com/abap/smartforms_sapscript.htm
    Sapscript vs Smartforms
    Difference with SMARTFORMS vs. SapScript(SE71)
    The Following are the differences :-
    a) Multiple page formats are possible in smartforms which is not the case in SAPScripts
    b) It is possible to have a smartform without a main window .
    c) Labels cannot be created in smartforms.
    d) Routines can be written in smartforms tool.
    e) Smartforms generates a function module when activated
    Scripts are client dependent whereas smartforms aren't.
    Upto 99 main windows are possible in scripts and only one in smarforms.
    To create multiple main windows in scripts, you just have to give the window type as MAIN whnever you create a window.
    Scripts still exists but smartforms are in use from 4.6c version, now the lastest version of these two is adobe forms
    SAP Smart Forms is introduced in SAP Basis Release 4.6C as the tool for creating and maintaining forms.SAP Smart Forms allow you to execute simple modifications to the form and in the form logic by using simple graphical tools; in 90% of all cases, this won't include any programming effort. Thus, a power user without any programming knowledge can
    configure forms with data from an SAP System for the relevant business processes.
    Advantages of SAP Smart Forms
    SAP Smart Forms have the following advantages:
    1. The adaptation of forms is supported to a large extent by graphic tools for layout and logic, so that no programming knowledge is necessary (at least 90% of all adjustments). Therefore, power user forms can also make configurations for your business processes with data from an SAP system. Consultants are only required in special cases.
    2. Displaying table structures (dynamic framing of texts)
    3. Output of background graphics, for form design in particular the use of templates which were scanned.
    4. Colored output of texts
    5. User-friendly and integrated Form Painter for the graphical design of forms
    6. Graphical Table Painter for drawing tables
    7. Reusing Font and paragraph formats in forms (Smart Styles)
    8. Data interface in XML format (XML for Smart Forms, in short XSF)
    9. Form translation is supported by standard translation tools
    10. Flexible reuse of text modules
    11. HTML output of forms (Basis release 6.10)
    12. Interactive Web forms with input fields, pushbuttons, radio buttons, etc. (Basis-Release 6.10)
    Reward Points if useful.

  • What is the difference between undo tablespace and online redo log files.

    what is the difference between undo tablespace and online redo log files. I am confused
    as per my knowledge undo tablespace is used to store the undo information when a table is being updated so that, just incase we need to rollback a transaction we know what was present in the table earlier.
    when a transaction fails the SMON performs the rollback of the data.
    This undo data is stored in the undo tablespace and read consistency if any is enforced.
    is my understanding till here correct?
    Now, can this undo data/before image not be stored in the redo log buffer and online redolog files?
    can redo-log files not store this information?
    in fact, is it that when undo tablespaces exist in a database, the undo data/before image is stored in both the undo tablespace and also the redo log files?
    kindly clarify my doubt.
    thank you.

    This question has been asked many times before. The answer is always the same.
    Yes, redo contains the before image of data (and the after-image). Therefore, it **COULD** be used to roll back a transaction.
    BUT... Redo is written sequentially. Using it to rollback your transaction would involve reading through all the redo written by maybe thousands of other people. It would be painfully slow.
    Your transaction is, however, directly linked to just the UNDO that it generates (which is JUST the before image of the data). So, your undo is your undo and doesn't share space with anyone else's undo. Therefore, using it to roll back YOUR transaction is fast.
    The fact that undo is only the before image of the data also makes it faster than wading through a sea of before and AFTER images as you'd find in redo. About twice as fast, in fact, since there's half the data. Roughly.
    Redo also gets written and flushed to disk whenever there's a commit, 3 seconds are up or too much (1MB, actually) redo gets generated between flushes caused by other factors. Your redo gets flushed when those things happen, even if you haven't actually committed your transaction. And redo logs recycle themselves, meaning that your redo -even if your transaction hasn't been committed yet- can be over-written by later transactions. Try rolling back when that's happened, if redo was the source of your rollback data!
    Undo, however, cannot be over-written if the transaction has not been committed. Ever. If you don't commit for three years, there will be three years' undo stored in your database (assuming you had the space, of course!).
    I could go on, but that will do. Redo is there fore RECOVERY, after catastrophe. Undo is there for read-consistency (and the occasional change of mind). Two different functions. Two different mechanisms. Each one highly tuned to doing what it does, why it does it, most efficiently and effectively.
