How to access ouput of one async process in another async process

Hi
I have two asynchronous processes.In the second process i would get all the data of a particular purchase order. how do i need to access this information in first process. when i do an invoke acitivity it's not generating any o/p variable .pls help me out on this
thanks
ravi

You need to put a "Receive" activity where you want to receive you asynchronous answer and link it to your partner link. Then you'll be able to create an output variable.
Have fun!

  • How to access a method in webservice catalogued component in BPM Process

    Hi
    Can anyone explain me how to access a method in webservice catalogued component in BPM Process using an imported jsp in bpm process.
    Thanks & Regards
    Ashish

    If Class B only has a reference to an Interface A, and that reference points to a concrete instance of Class A, then of course Class B can still call the method on Interface A. The method for concrete instance Class A is called behind the scenes.
    That's how interfaces work. That's what they're good for.
    Look at the code in the java.sql package for examples. Connection, Statement, ResultSet - all are interfaces. But behind the scenes you're using the concrete implementations provided by your JDBC driver. You don't know or care what those classes are or their package structure. All you do is make calls to the java.sql interface API, and it all works. - MOD

  • How to pass data from one internal session to another internal session

    hi all sap experts ,
    How to pass data from one internal session to another internal session and from oneExternal session to another external session.
    Except : Import and Export parameters and SPA/GPA parameters.
    Tell me the otherWay to pass data ..
    Plz
    Thanks in advance

    hi,
      abap memory management u will understand about this concept.
    the import /export parameter will help u that passing data between two internal sessions by using abap memory.

    Passing Data Between Programs
    There are two ways of passing data to a called program:
    Passing Data Using Internal Memory Areas
    There are two cross-program memory areas to which ABAP programs have access (refer to the diagram in Memory Structures of an ABAP Program) that you can use to pass data between programs.
    SAP Memory
    SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens (see below).
    ABAP Memory
    ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse. For further information, refer to Data Clusters in ABAP Memory.
    Filling Input Fields on an Initial Screen
    Most programs that you call from other programs have their own initial screen that the user must fill with values. For an executable program, this is normally the selection screen. The SUBMIT statement has a series of additions that you can use to fill the input fields of the called program:
    Filling the Selection Screen of a Called Program
    You cannot fill the input fields of a screen using additions in the calling statement. Instead, you can use SPA/GPA parameters. For further information, refer to Filling an Initial Screen Using SPA/GPA Parameters.

  • How to pass data from one internal session to another

    Hi SAP Experts,
    How to pass data from one internal session to another and from One external session to another external session. I used import and export parmeter and SPA/GPA parameters. What is the other way to pass data?

    Thank you

    Memory Structures of an ABAP Program
    In the Overview of the R/3 Basis System you have seen that each user can open up to six R/3 windows in a single SAPgui session. Each of these windows corresponds to a session on the application server with its own area of shared memory.
    The first application program that you start in a session opens an internal session within the main session. The internal session has a memory area that contains the ABAP program and its associated data. When the program calls external routines (methods, subroutines or function modules) their main program and working data are also loaded into the memory area of the internal session.
    Only one internal session is ever active. If the active application program calls a further application program, the system opens another internal session. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack.
    The memory area of each session contains an area called ABAP memory. ABAP memory is available to all internal sessions. ABAP programs can use the EXPORT and IMPORT statements to access it. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
    All ABAP programs can also access the SAP memory. This is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters are often used to preassign values to input fields. You can set them individually for users, or globally according to the flow of an application program. SAP memory is the only connection between the different sessions within a SAPgui.
    The following diagram shows how an application program accesses the different areas within shared memory:
    In the diagram, an ABAP program is active in the second internal session of the first main session. It can access the memory of its own internal session, ABAP memory and SAP memory. The program in the first internal session has called the program which is currently active, and its own data is currently inactive on the stack. If the program currently active calls another program but will itself carry on once that program has finished running, the new program will be activated in a third internal session.
    Data Clusters in ABAP Memory
    You can store data clusters in ABAP memory. ABAP memory is a memory area within the internal session (roll area) of an ABAP program and any other program called from it using CALL TRANSACTION or SUBMIT.
    ABAP memory is independent of the ABAP program or program module from which it was generated. In other words, an object saved in ABAP memory can be read from any other ABAP program in the same call chain. ABAP memory is not the same as the cross-transaction global SAP memory. For further information, refer to Passing Data Between Programs.
    This allows you to pass data from one module to another over several levels of the program hierarchy. For example, you can pass data
    From an executable program (report) to another executable program called using SUBMIT.
    From a transaction to an executable program (report).
    Between dialog modules.
    From a program to a function module.
    and so on.
    The contents of the memory are released when you leave the transaction.
    To save data objects in ABAP memory, use the statement EXPORT TO MEMORY.
    Saving Data Objects in Memory
    To read data objects from memory, use the statement IMPORT FROM MEMORY.
    Reading Data Objects from Memory
    To delete data clusters from memory, use the statement FREE MEMORY.
    Deleting Data Clusters from Memory
    please read this which provide more idea about memory

  • How do you switch from one iTunes account to another on your apple tv?

    How do you switch from one iTunes account to another on your apple tv?

    Welcome to the Apple community.
    I assume you do mean a different account and not simply a different iTunes library. Unfortunately, in order to switch accounts, you would need to log out and log in to the second account.

  • HT201320 How can I switch from one email user to another?

    How can I switch from one email account to another?

    You have to select between the two accounts in the mail app.
    Say for instance that you are reading an email in your XYZ email account. Tap the button in the upper left corner of the mail app to back out all the way to where you can see all of the email accounts.... Tap InBox, then tap XYZ email Account and that will take you back to the main MailBoxes window.
    Is that what you want to know? There is no way to simply "toggle" between the two accounts.

  • How to move Tablespace from One disk group to another disk group in RAC

    Hi All,
    I have 11gR2 RAC env on Linux.
    As ofnow I have problem with disk group. I have 3 disk group which is almost full - 98%. I have added one NEW disk group and want to move some of the Tablespace(TBS) from OLD disk group to NEW diskgroup and make some free space in OLD disk group.
    Can any one suggest me how to move TBS from one disk group to another disk grup without shutting down the instance.
    DB is in Noarchive mode.

    Hence I am trying something and findout below steps but not sure how useful it is:

    2- Copy the file to new diskgroup using Either RMAN or DBMS_FILE_TRANSFER.
    3- Rename the file to point to new location.
    4- Recover the file.
    5- Bring the file online.
    I had move 240M TBS from OLE to NEW.
    These steps run successfully so I think this is valid for noarchive mode.Hence want to confirm..so inform me please.
    Thanks :)I have doubt in my mind:
    1. You database is in noarchivelog mode
    2. You're taking tablespace offline
    3. Suppose you're moving a file of size 10GB(or any larger filesize) to another disk group
    4. Now after moving the file, you're trying to bring the tablespace online............NOW
    tablespace will need recovery. if the required data is inside the SGA then it is ok. But if the data has been flushed, then?
    if step 2 and 3 has taken significant time, then most probably you'll not be able to bring that tablespace online.

  • How to access an attribute(this is referencing to another class) in a class

    Dear Gurus,
    I have to read an attribute of a class and that attributes type another class.
    I have intantiated the class and my question is how to read the attribute. I know I can not dirrectly read the attribute since this is another class. I think I have to first reference the attribute right? Please advise me.
    My code looks like below:
    data: lo_fpm                                 type ref to if_fpm.
    data: lo_msg_mgr                        type ref to if_fpm_message_manager.
    data: lo_component_manager    type ref to cl_fpm_component_manager.
    lo_fpm = cl_fpm_factory=>get_instance( ).    " cl_fpm_factory is a class which has a static method get_instance
    lo_msg_mgr = lo_fpm->mo_message_manager.
    lo_component_manager = lo_fpm->mo_component_manager.
    The above statement is giving syntax error. I do not know why.
    The basic difference b/n the two methods is if_fpm~mo_message_manager    type ref to if_fpm_message_manager    and
    mo_component_manager     type ref to cl_fpm_component_manager.
    Any help would be appreciated.

  • Calling BPM Sub Process from another BPM Process - Stuck at Sub Process

    Hi
    JDeveloper 11.1.1.6, BPM 11.1.1.6, WLS 10.3.6
    I am trying to Call a BPM Process from another BPM Process. Both the processes are defined in the same BPM Project.
    Both the Processes have 'None' Start and End activities.
    The 'Parent Process' has a 'Call Activity' which calls the 'Sub Process'.
    The Sub process takes a parameter of payload object as input and returns output (also same payload object)
    I have passed the payload object from parent to sub process in the 'Data Associations'.
    The Start and End activities in the sub process also have the data associations set where I am passing the payload object from parent process to child process.
    When I run the process and see the Enterprise Manager console - Audit Trail / Flow tabs,
    Flow Tab - The progress of the process is showing only till the Calling of the sub process in the Parent Process. It does not show the Sub Process.
    Audit Trail Tab - Shows that the Sub Process is called but has not reached to the End of the Sub process.
    The audit trail does not have links to the sub process activities.
    I cannot see any exceptions as well in the audit trail.
    How can I find out why the process is stuck? Or what is going on in the process?
    Please let me know if my explanation is not clear?
    Thanks for any help
    Regards
    Sameer

    Thanks for replying.
    I have another Sub Process with Start and End events as Message Events and used Send Task and Receive Task (Implementation : Process Call) in the Main process to invoke the sub process asynchronously.
    Then, the Sub Process is shown in the 'Flow Trace' as child of the main process.
    In this particular one, I used 'Call Activity' to call the sub process.
    So the Audit trail is showing the sub process as a child.
    But what I was trying to say is that the audit trail did not have links to the entries in the 'Event' column (in Enterprice manager - instance window). (like Instance entered activity, Instance left activity etc).
    I was intending to use these links to see the payload information and try to debug if there is any problem with the code.
    The actual problem I was trying to say in the post is that, even after the user responds to the activity (User Task - Approval) in the Sub process,
    the audit trail is not proceeding further.
    In the Sub process definition, after the user task, there is End with none implementation.
    Hope it is clear now.
    Thanks and Regards

  • Invoking bpel process from another bpel process in same app server

    Hi,
    When I invoke a bpel process from another bpel process in the same oracle AS
    1. Is it a SOAP call or is there any optimization?
    2. If there is some optimization where can I configure this?
    3. Is there any similar optimizations if I invoke a bpel process from a
    java application deployed in the same server? If so can you please provide
    a sample?
    Thanks for your help
    Raj

    By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
    It can be configured at domain level:
    Parameter: optSoapShortcut (SOAP local optimization)
    Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
    The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".

  • How to handle more than one message coming from an async BPEL in a sync BPEL process?

    Here is the scenario,
    Sync process A is calling an Async process B and Async process B  is developed in such a way that it is returning more than one message to sync process A, how you will handle those messages in sync process A?

    As durga said, its a wrong design, you will have issues in real time. You wont get the response back most of the time. It can be otherway around, async is waiting for sync process.
    Change your design or provide what is your use case below, we can think of which design suits you.

    I have 2 game centers on 1 Apple ID and it will only access 1 of them may someone tell me how to access the other one

    You don't have to use the same ID for iCloud as you do for purchasing.  You can just set up iCloud using your other ID. 
    If your have already have another account, you have to go to Settings>iCloud, tap Delete Account, choose Keep on My iDevice when prompted, set up your new account with the other ID, turn on your iCloud data syncing and when prompted, choose Merge to upload your data to the new account.

  • How to move phones from one CUCM server to another?

    How easy is it to migrate IP phones from one CUCM server to another?
    The situation is this:
    A vessel currently sitting in dry dock has 14 IP phones onboard which currently register with a CUCM server half way round the world (literally). As you can imagine there is quite a fair amount of delay for the signal processing, not to mention the connectivity being over a VSAT link. This being a temporary solution.
    A CUCM server has been configured and installed on the vessel with all the relevant partitions, route patterns, trunks etc. The phones have also been added to the new server ready for migration. The only real thing that will be different when the phones are migrated is the Directory Number on each phone. Both CUCM servers are running software version 7.1.3
    The phones currently pick up their local IP addresses via a local DHCP server which assigns 150 TFTP Server IP Address for the remote CUCM server. Is changing the the TFTP Server IP address to the local CUCM server enough to have the phones register with the local server.
    This is not something I've tried before so would appreciate feedback or any comments that may indicate anything I missed along the way.
    Thanks,
    Ric

    Hi Ricardo,
    On the DHCP scope created for the voice vlan change the Option 150(TFTP Server IP address) to the new CUCM and remove/delete the remote CUCM IP address just to ensure that phones once after registering to the new CUCM will not fetch any config from the remote CUCM as the DN's of the phones are changed on the new CUCM please ensure this.
    Apart from this i dont see any challenges as the firmware of the IP Phones will also remain same as CUCM version is same.
    Hope that helps.

  • How to access constructor that is not public from another package

    Hi,
    We have a class that has a constructor in package se.company.internal that looks like:
    DraHw(){
    Then from a HwTest class ( packge se.company.function.hw) we want to access this class but we cannot make the constructor public.
    Any ideas on how we can create an instance of DraHw when testing without making constructor public?
    br,
    //mike

    > we want
    However do you in fact actually need to?  And if you do that are you breaking the design of the other app?  Obviously there is in fact a way to create the class so perhaps you should study that first to insure that there is not some designed way to do what you want.
    > How would that 1:1 one class look like?
    I REALLY suggest that you look at the original design again.

Maybe you are looking for
