How to create global toolbar for some common operation like add, delete etc

Hi,
I want to create one global toolbar which contains buttons for common operations such as add, delete, modify etc.
I have one globl .jspx page and in its center facet, I am loading my each screen's .jsff page.
Now I want to create global toolbar on my .jspx page and when I click on toolbar's add button at that time it should call, currently loaded .jsff (loaded in center facet of .jspx page) backing bean's add method.
How can I get the instance of currently loaded .jsff backing bean in my toolbar's backing bean and also I need it with its current state( means whatever UI components have values I should be able to get it in my instance).
Regards,
Devang

Hi,
since page templates don't support method expression arguments there are two options I can imagine
- define a contract between the toolbar buttons and the availability of a managed bean available for the consumer page. If for example each page has a managed bean like <viewId>_toolbar then the Toolbar could reference exposed methods on this bean (which must be consistent)
- Another option is to have the page passing in the EL string to access the iterator to operate on as an attribute of the template you use. Then you create a ValueExpression from it and call it for the button action events that you point to the managed bean you deploy with the template

  • How to create global groups for end users

    Just started deployment of Lync 2013.  We do not host our exchange / mail internally.  It is a hosted solution (not exchange).  We do use outlook though.
    It has been a long time since I set up Lync (Since OCS 2007 / 2007 R2)
    Can someone please tell me how to create groups for all users on the Lync Client and populate them from groups in AD.Right now we are using Spark and we have decided to use Lync.  In Spark it queries AD every day and populates the groups from AD
    groups that we have defined.
    I know that users can create there own groups, but we prefer to have every client have every group (department) and those in department listed below rather than them have to manually add them individually.
    Thanks for your direction.
    John

    Hello john,
    Lync Client can't use AD group or Exchange mail group. You can't create Lync client group with AD GPO. each Lync user can create their own group in Lync client and of course can delete.
    You can not manage Lync client within the
    group as the centeral. There is no such
    feature in Lync. you can examine 3rd party applications. for example ;
    http://www.vytru.com/contacts-manager-for-microsoft-lync.html
    Regards
    Zulfikar CAGLAR
    The statement is incorrect. You CAN use Distribution Groups from Active Directory in Lync Client:

  • How to create global object for a number of views?

    Hello,
    Let's say I have 5 different views in a certain component.
    I would like to open a connection to a DB and share this connection between all views.
    Can somone please show/explain me where do I do it on the component and how do I access this connection from the views?

    Hi Roy,
    For getting the connection, you can create the datasource in the "Visual Administrator" and you can get the connection from the datasource. By doing this, you can retrive the connection from the connection pool.
    Refer the link to create the datasource and accessing it from the java code.

    How To Ask Questions The Smart Way
    Eric Steven Raymond
    Rick Moen
    Write in clear, grammatical, correctly-spelled language
    We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
    So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
    Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
    More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

  • How to create a PR for each Maintenance Order

    Dear All,
    Please guide me how to create a PR for each Maintenance Order.
    I test on Ides, I have some Maintenance Orders, all of them require the same stock material. When I run MRP, system always create one PR for all requirements. I don't know how to change.
    Regards,
    QuangDD

    Hi,
    As you planning for Stock Items, by running MRP, system will create single PR only. If it is non stock items, then it would be possible to create different PR based on Orders.

  • How to create a object for IPageItemControlData?

    how to create a object for IPageItemControlData?

    From the header comment you'll see that IPageItemControlData is an Interface of PageItemWidget. That must've been an InDesign 1.0 or 1.5 feature predating kPageItemBoss, because except for the same comment even in InDesign 2.0 SDK the only further reference is a copy in the comment of its sibbling IFrameControlData which was removed with InDesign CS.
    The IID and kPageItemControlDataImpl are probably only around because deep under the hood there must be some kind of conversion provider waiting to do its job on a very old document.
    I guess the closest in today's functionality will be IHierarchy.

  • How to create an extension for generated type idoc

    Hi all,
    Can u please look into this
    How to create an extension for generated type idoc ?  for example Idoc type BATMAS02

    Enter transaction WE30 (ALE->Extension-> IDOC types->Maintain Idoc type)
    - Type in your name of the extended IDOC type (usually starting with 'Z') and click on the Basic IDoc type, click the create icon.
    - Click on Create new and enter a description and press enter.
    - Click on ZIDOCTYPE01 and then on the Create icon.
    - Enter ZIDOCTYPE as the segment type, click on Segment Editor.
    - Enter a description for your segment type and create.
    - Enter a description for your segment, enter each field required in your IDoc and press enter to validate.
    - Save and generate, press back
    - To release the segment choose Goto, Release from the menu.
    - Check the box on the line of your segment.
    - Save, back and enter.
    - Your Idoc type structure should be displayed with your new segment.
    - Save and back.
    - To release the Idoc type choose Extras, Release type from the menu and Yes.
    ALE FUNCTION MODULE ENHANCEMENTS
    Having extended the IDOC type to contain additional fields for an inbound or outbound application, you now want to enhance ALE function modules for populating the additional segment on the outbound or applying the additional segment data on the inbound application.
    The core working code for ALE processes for a given application area is always encapsulated in ABAP/4 function modules. These function modules are associated with such control information as message types and process codes. So the ALE process checks this control information and derives the name of the function module to invoke for that particular IDOC processing from certain database tables. These function modules contain objects known as customer functions, which can be considered SAP Enhanced user exits. A function module is called at a particular point during the processing of the main program or function module, and it can be used to influence data processing at that point by adding code to the customer function. The customer function behaves like a normal function module and has import and export parameters, tables (internal tables) statement, and exception processing. Unlike a conventional user exit, customer functions give you the ability to modify only data available to you by the function moduleâs parameters and internal tables. While most ALE/EDI function modules are supported by customer functions, there are ALE/EDI processes that still use conventional user exits. There are a few ways to determine which function module to enhance for a given message type/process code:
    • For master data distribution, from SALE go to Extensions -> Master data distribution -> Setup additional data for message types. Search for message type DEBMAS in this example. You see an entry for DEBMAS associated with function module MASTERIDOC_CREATE_SMD_DEBMAS. This data is stored on table TBDME. The function module names for all master data message types follow this pattern: MASTERIDOC_CREATE_SMD_messagetype. This function module calls another function module of name MASTERIDOC_CREATE_DEBMAS or MASTERIDOC_CREATE_messagetype. Search for the words customer function, and you find several hits that can be used to add code to the function module.
    • From WEDI got to Control -> Inbound process codes -> Inbound with ALE service -> Processing by function module (transaction WE42), or from WEDI go to Control -> Outbound process codes -> Outbound with ALE service -> With function module (transaction WE41). There will be function modules associated with the process codes. For inbound, the function modules usually follow this pattern: IDOC_INPUT_messagetype: for example, IDOC_INPUT_CHRMAS for inbound characteristics master.
    • Use transaction WE57 or from WEDI go to Development -> Message/Application Object. The entries list the function module, Business Object, message type, and IDOC type that are used for inbound ALE/EDI interfaces.
    Customer functions are not specific only to ALE and EDI but also to all programs/modules in SAP R/3. Customer function is a SAP enhancement component; the other two types are menu and screen enhancements.
    All customer function exits are maintained in SAP enhancements and are found by using transaction SMOD. After executing transaction SMOD, pull down (F4) on the enhancement name field, and execute again. This provides you with a list of all SAP enhancements available. SAP enhancements are grouped by development class pertaining to an application area. Choose Application development R/3 SD master data distribution for development class VSV to lead to a screen that lists VSV00001 as an enhancement (see Figure 5). Press Component +/- to display its function exit components. There are four possible components listed, all of which are function exits (and are function modules) that are called from the ALE function modules in the form Call Customer Function Î001â. This is a special occurrence of the ABAP statement Call. Go to item Exit_SAPLVV01_ 001, which you need to enhance for the Customer Master outbound example of an IDOC extension. In the ALE-function module MASTERIDOC_CREATE_DEBMAS, the statement CALL Customer Function 001 is translated in the background to call component EXIT_SAPLVV01_001. Although this function exit can be edited using transaction SE37, you will use a simpler approach.
    When you use SAP enhancements and their components, you manage them with an SAP object known as a project, which is like an envelope containing the selected enhancements and their components. A project can be used to control the execution of components and to transport them to other clients and instances in SAP. Basically, the process involves creating a project, including enhancements and components that are to be enhanced, editing the components, and then activating the project. The following process creates a project for our example Customer Master IDOC extension:
    • Execute transaction CMOD.
    • Enter name of project, say CSTMAST1.
    • Click on Create.
    • Enter a description of the project.
    • Save.
    • Click on SAP Enhancements.
    • Enter VSV00001 for Enhancement.
    • Save.
    Once youâve created the project, edit the function exit components and activate the project. Remember that the code in the function exit enhancement will execute only if the project is activated. In fact, this is a convenient SAP enhancements feature, whereby the work in progress (developing code in the customer function) will not affect users of that application. When the code is completed, the project can be activated so the enhanced functionality takes effect. It can also be deactivated for maintenance.
    As mentioned earlier, customer functions (function exits) are embedded in ALE function modules and can be used to influence the creation and modification of IDOC data on an outbound application or to post additional or modified IDOC data to an inbound R/3 application. Function exits are similar to regular function modules, with import/export parameters, tables (internal tables), and exceptions.
    The two important factors to consider while developing the customer function are:
    1. The point in the ALE function module where the function exit occurs
    2. The data made available by the customer function that can be modified or posted to the R/3 application, based on the direction.
    Because some function modules have several customer functions, it is critical to choose the function exit best suited for that particular enhancement. Do not attempt to perform activities that the function exit is not designed for. The importance of this point is illustrated by the following description of enhancing function modules for outbound and inbound ALE interfaces.
    Outbound interfaces. In an outbound ALE interface you use function exits (customer functions) to populate additional segments created by an IDOC extension or to modify the existing IDOC data segments as per business requirements. Previously, you identified that enhancement VSV00001 has a component EXIT_SAPLVV01_001 (function exit), which can be used for populating the additional data segment Z1SADRX that you created in the IDOC extension ZDEBMASX (IDOC type ZDEBMASZ, based on Basic IDOC type DEBMAS02). You also learned that the ALE function module that calls this function exit is MASTERIDOC_CREATE_DEBMAS, which has a statement Call Customer Function 001.
    Browse the function module MASTERIDOC_CREATE_DEBMAS using transaction SE37. You will find that this customer function is invoked for every segment of IDOC type DEBMAS02. In fact, the function exit is called soon after the creation of an existing segment has been populated with data and appended to the IDOC data table (internal table). Also, the function exit is exporting the message type, IDOC type, and the segment name and is importing the IDOC extension type. It is also passing the IDOC data internal table. This indicates that the ALE function module is allowing you to populate additional segments for every existing segment and modify the existing segmentâs data.
    Letâs write ABAP/4 code to accomplish the task of populating IDOC segment Z1SADRX with a contact personâs business address:
    • From SE37, display function module MASTERIDOC_CREATE_ DEBMAS.
    • Find Customer Function 001.
    • Double-click on 001.
    • The function EXIT_SAPLVV01_001 will be displayed.
    • Double-click on INCLUDE ZXVSVU01.
    • You will be asked to create a new include object. Proceed as desired.
    • Enter code (as in Listing 1).
    • Be sure to perform a main program check (Function Module -> Check -> main program) and extended program check (Function module -> Check -> Extended check).
    Now that you have extended the IDOC and enhanced the ALE function module based on the requirements for the contact personâs business address on the Customer Master, letâs test the interface. You should create a logical system and define a port for this interface. You should also configure the Customer Distribution Model to indicate that message type DEBMAS is being distributed to this logical system. The only difference in configuration between a regular outbound ALE interface and an enhanced one is the partner profile definition. While maintaining the outbound parameters of the partner profile, make sure the IDOC type is ZDEBMASZ. The fields for Basic IDOC type and extension type are automatically populated with DEBMAS02 and ZDEBMASX, respectively.
    To maintain the contact personâs business address of a customer:
    • Use transaction BD12 or from BALE go to Master Data ->Customer -> Send and send that Customer Master record by executing the transaction after filling in the relevant fields such as customer number, message type, and logical system.
    • Use transaction WE02 or WE05 to verify the IDOC created. You should see the new segment Z1SADRX populated with the correct data.
    With SAP releases below 4.5B, you cannot capture changes to business address through change pointers because a change document object is not available for capturing business address changes, and also earlier releases have not been configured to write change documents for a contact personâs business address. If you would like this functionality, you can either create change document objects, generate function modules to create change documents, and perform ALE configuration to tie it in, or make a cosmetic change to the contact person screen data while changing the contact personâs business address so that it gets captured as a change to the Customer Master. Subsequently, the ALE enhancement that you performed captures the contact personâs business address.
    Inbound interfaces. The process for enhancing inbound ALE interfaces is similar for outbound, with a few exceptions; specifically in the coding of customer functions (function exits) for the ALE/EDI function modules.
    The first step is to create an IDOC extension for the specific Basic IDOC type by adding new segments at the appropriate hierarchy level: that is, associated to the relevant existing segment. Populate the data fields on the new segments with application data by the translator or external system/program before importing them into the R/3 System. Then, find the ALE function module that is invoked by the inbound processing. By browsing through the code or reading the documentation on the function exit enhancements using the SMOD transaction, identify the function exit in which you should place your code. The technique used in the code to post the additional or modified IDOC data to the application can vary based on the application rules and requirements, the data available at that point in processing, and the application function modules available to update the application tables. It is important to search first for application modules that process the data and see if they can be called within the function exit. If the additional data in the extended segments in specific to a custom table or resides in nonkey fields of a single or small set of tables, you may be able to update it directly by SQL statements in the function exit. This approach should be carefully evaluated and is certainly not highly recommended.
    Another option is to use Call Transaction from within the function exit to process the additional data. For example, in the case of message type WMMBXY for inbound goods movements from a warehouse management system, the standard interface creates batches for materials, but does not update its characteristics. In such a case, you can use Call Transaction MSC1 to create the batch and assign characteristic values to it from within the function exit provided.
