How to pass data from one Form to another Form

I am writing a Login form to allow user to access MySQL but the Authentication is taking place in another form that actually does the work
how do I pass the username and password form the Login form to the worker form.

1. don't do these stuffs on the UI classes, let them only be responsible for displaying UI.
As for the passing information back and forth from separate objects (forms are classes and form instances are objects) you can read up on the various appropriate design patterns, especially those implemented in MVC models.

How to pass data from one session to another?

What does SAP memory use to pass data between sessions?
What is the syntax of "Export to ..."? Where is it used?

hi suman vijay,
EXPORT obj1 ... objn TO MEMORY.
Exports the objects obj1 ... objn (fields, structures or tables) as a data
cluster to ABAP/4 memory .
EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key. Exports the objects obj1 ... objn (fields, structures or tables) as a data cluster to the database table dbtab.
IMPORT f itab FROM MEMORY.
Imports data objects (fields or tables) from the ABAP/4 memory . Reads in all data without an ID that was exported to memory with "EXPORT ... TO MEMORY."
IMPORT f itab FROM DATABASE dbtab(ar) ID key. imports data objects (fields, field strings or internal tables) with the ID key from the area ar of the database dbtab .
EXPORT obj1 ... objn TO MEMORY.
If you call a transaction, report or dialog module (with CALL TRANSACTION , SUBMIT or CALL DIALOG ), the contents of ABAP/4 memory are retained, even across several levels. The called transaction can then retrieve the data from there using IMPORT ... FROM MEMORY .
Each new EXPORT ... TO MEMORY statement overwrites any old data, so no data is appended.
EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key
The database table dbtab must have a standardized structure .
The database table dbtab is divided into different logically related areas ( ar , 2-character name).
You can export collections of data objects (known as data clusters ) under a freely definable key (field key ) to an area of this database.
IMPORT allows you to import individual data objects from this cluster.

How to pass data from one component to another

Hi all,
We have added a button on "ICCMP_BTSHEAD" component, which will open a new popup component (Zcomponent), which will have some fields related to the order. Can anyone please tell us how to pass the ticket/ entity value to the new component so that it can be used there. Any pointers will be highly appreciated. Thanks.

How to pass data from one page to another

i have a table with multiselect and i want that in the moment i select some rows and press on a button in the other page should be displayed only those data i have selected from previous one.... how can i do this? any link or example for this case?
thanks in advance :)

If the data you are retrieving from the excel file is just a few fields, then you can get them all on the first page and store them as public variables and use those variables on the different pages. But if you are getting a lot of data per page, then it would still be a good idea to get them all on the first page but store them as arrays. Then, on each page you can use the array you need.

How to pass Data from one form to the other

Hi all
Can any one suggest me how to pass data from one form to the other form, which i zoomed from the original one?
I tried to do this by passing parameter in Event Procedure but i am getting error msg when i am opening the zoomed form.
If any one of u have any idea, give me a reply
Thank you
Suhasini

If you choose the second alternative you should erase these global variables after the second form is opened
You can erase the global variable using:
erase('global_var')

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,

Solved!
Go to Solution.

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

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 ..

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.

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

OBIEE 11g How to pass variable from one prompt to another prompt in dashboard page.

How to pass variable from one prompt to another prompt in dashboard page.
I have two prompt in dashboard page as below.
Reporttype
prompt: values(Accounting, Operational) Note: values stored as
presentation variable and they are not coming from table.
Date prompt values (Account_date, Operation_date)
Note:values are coming from dim_date table.
Now the task is When user select First
Prompt value “Accounting” Then in the
second prompt should display only Accounting_dates , if user select “operational”
and it should display only operation_dates in second prompt.
In order to solve this issue I made the
first prompt “Reporttype” values(Accounting, Operational) as presentation
values (custom specific values) and default presentation value is accounting.
In second prompt Date are coming from
dim_date table and I selected Sql results as shown below.
SELECT case when '@{Reporttype}'='Accounting'
then "Dates (Receipts)"."Acct Year"
else "Dates (Receipts)"."Ops
Year" End FROM "Receipts"
Issue: Presentation variable value is not
changing in sql when user select “operation” and second prompt always shows
acct year in second prompt.
For testing pupose I kept this presentation
variable in text object of dashboard and values are changing there, but not in
second prompt sql.
Please suggest the solution.

You will want to use the MoveClipLoader class (using its loadClip() and addListener() methods) rather than loadMovie so that you can wait for the file to load before you try to access anything in it. You can create an empty movieclip to load the swf into, and in that way the loaded file can be targeted using the empty movieclip instance name.

How to pass data from one UIBB to anothere UIBB in OIF/GAF - FPM

Dear all,
as of now i am using FPM only for displaying data from different components.
now i would like to pass the data from one UIBB to another by calling second UIBB on action of a button. (instead of using standard path in GAF scenario)
how could i achieve this. is there any difference mechanism's for UIBB's of single component and UIBB's from different different components.
it would be great if some one can explain or help me reg this issue on both OIF and GAF FPM's.
Thanks in Advance.
Best Regards,
Kranthi kumar Palle.

I've actually combined these two approaches to data sharing - I've passed a class reference in the shared data component. This is nice (in my opinion) because it is very obvious where the data is coming from and who it is shared with. It also means that there is not a huge overhead in passing data through the shared context, because you are just replicating a reference to a class instance.
And - you don't have to deal with singleton classes :-). So if you want/need to extend your implementation at a later date (for example embedding multiple instances of the same "app" in the one window - or suspending and resuming to another instance of the same app you can then do this. (NB - suspend resume to launch another FPM app does not work because of this (amongst other things)).
NB a shared data component need not be faceless! I certainly have "shared data" UIBBs that also have UI components - possibly not best practice - but it certainly can be done.
Cheers,
Chris

Passing data from one frame to another frame

hello all, i am having a problem with passing data from one frame from another. I have a main frame when you click on connect button it display the second frame(class) that has 2 text fields and 2 buttons. When i click on connect it check if the data is correct. If the data is correct i want that frame to close and pass the data back to main frame. How can i do that.
thank you

hello all, i am having a problem with passing data
from one frame from another. I have a main frame when
you click on connect button it display the second
frame(class) that has 2 text fields and 2 buttons.
When i click on connect it check if the data is
correct. If the data is correct i want that frame to
close and pass the data back to main frame. How can
i do that.
thank you
the original problem sounded like an ideal opportunity to use Modal Dialog. if you want one frame to display another to get user input then you need to stop the method in the main frame from executing until you recieve a valid input.
you can use your own class and keep all of the components that you have in the connect frame but you would have to extend JDialog instead of JFrame.
there is a way around it!
if you must use JFrame for both, then you need to have access to the main frame in the connect frame, maybe pass the pointer to the constructor??
anyway, when the connect frame is done with its duties, you have to use the pointer to call another method in the main frame that will continue the process. otherwise main frame doesn't know when connect frame is done and by that time, the method in main frame that instantiated the connect frame has long since died.
also, it allows things to happen in the other window that you may not want to happen until the connect frame is done
typically users of software start clicking around on things and you could have three or four connect frames going at the same time
it's really best to use a Modal Dialog, it really can look just like a JFrame!!!!!!!!!!!!!!

Pass data from one VI to another one

Hi,
I try to control a event structure in a VI with a boolean command from a second VI. I have been advised to "build a connector to pass any data from one VI to another one".
Below an simple example: my goal is MyVItwo gives the result of a 2 numbers addition only when the boolean "MyBooléen" value changes in MyVIone.
How can I realise this?
Thanks
PB

It is not entirely clear what you are trying to do. I think that what you want is a main vi/subvi setup. The boolean control would be in the main vi and would be monitored by an event structure. When the value of the boolean changes the subvi would be activated. I have attached an example showing how this is done.
In order to use a vi as a subvi you build a connector box. In order to do this you just right click on the vi icon at the top right of the front panel and select show connector. You then wire connections on the connector block to controls on the front panel. You insert the subvi into your main vi by choosing "Select a vi" on the functions pallette and browsing to the subvi.
If you absolutely have to pass the data from one vi to another while running in parallel there are a number of ways to do it. Global variables will certainly work but are generally avoided by experienced LabVIEW programmers due to their potential caveats and the break in data flow. An alternative to global variables is the functional global, also called a LV2 style global. This is basically a non-reentrant subvi with an unitialized shift register which allows for data to be stored. For more information search this forum for LV2 globals.
Another alternative is to obtain a reference to the control and operate on that reference. You could also use queues, notifiers, or occurences. Search the examples which shipped with LabVIEW for examples on using these operators.
If you need any more information feel free to post back here.

Passing data from one screen to another(web-dynpro) in SRM sourcing cockpit

HI Experts,
i am facing problem in passing data from one web-dynpro screen and assigning the data it to another web-dynpro screen.
my requirement is that when ever user selects a contract in PROPOSE SOURCES OF SUPPLY screen popup and press only assign only button, the data of the contract should be copied to the shopping cart.
i have already used the BADI BBP_DOC_CHANGE_BADI, but unfortunately it was not working.
so i tried to use the context, element and other web-dynpro fields to pass the data, i am able to pass the data from the popup to the second screen and able to assign it.
but when ever i deselect the shoppping cart which has been assigned with the data of the popup and select another shopping cart the data of the above shopping cart is cgetting changed.
i am unable to figure out the exact reason why this is happeing.i have written code in the ASSIGN ONLY button method to fetch the popup data and in the WDONMODIFYVIEW method of the second screen to assign the popup data to the shopping cart.
i have tried to bind the elements using the BIND_TABLE, BIND_STRUCTURE, BIND_ELEMENT, BIND_ELEMENTS methods, but nothing is working.
can anyone suggest me where i am making mistake and try to solve the issue.
Thanks
Tanveer
