Link BOR Event with ABAP code (program or function)!

Hello experts,
I am trying to link program or function to bor event. Change of data in HR IT0002 trigger event CHANGE of PERSDATA Object. I need to execute some ABAP code (program or function) on CHANGE event, so I have to link event and ABAP code.
Question: is it possible and how?

Hi,
It is very much possible....
You can use the Workflow & use BO as PERSDATA & this workflow can be triggered on event change.
& You can write your code ...

Generate BEx Variant with ABAP

I would like to create lot of BEx Variant automaticlly on a Workbook. But now, I just found the Variant stored in table VARID(ID) , VARIT (Text) , VARI ( ? ) and TRDIR .
But the data which stored in these tables are not I want.
How could I do this ?
Thank you.

Liang,
What is the version of BW/BI (3.x or 2004s) you are using?
In BW 3.x these are stores in VARI & VARID
In BI 2004s these are in RSRVARIANT & RSRVARIANTDIR
You can look athe function modules RS_VARIANT_CREATE, RS_VARIANT_DELETE and RS_VARIANT_EXISTS.
But if you are using 2004s , forget it these functions are not useful anymore.because when you create variants in 2004s they gets stored in RSRVARIANT & RSRVARIANTDIR, but the function modules are looking at VARI & VARID tables.
Hope this helps.

Can I use AWT elements in a JSP, and so could I generate events with them?

This is because I�m doing a simple JSP that showing a button, my JSP is:
<html>
<%@ page import="java.awt.*" %>
<%! Button b = new Button("Hola!!!"); %>
<% add(b); %>
</html>
But when I tried to see the button in the browser, my JSP generates the following:
Compilation of '/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java' failed:
/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java:79: cannot resolve symbol
probably occurred due to an error in /gep/alterno/23_mayo/mr4.jsp line 7:
<% add(b); %>
Could somebody help me please?.....
Can I use AWT elements in a JSP, and so could I generate events with them?
Thanks!!!

There are 2 ways to run a web page dynamically:
1) Reload the page via use of javascript or some other scripting language.
2) Use an applet to regularly check a URL for the data
Remember, as Paul pointed out, JSP's only generate HTML output. AWT components need to run inside a JVM not a just the browser.
I could recommend an applet but you may have problems with IE6 not supporting java. Otherwise there shouldn't be too much of a prob.
If you prefer to use an AWT/Swing setup (for example an application) rather than a JSP setup, Webstart is good for delivering online applications which operate standalone or remotely.
When you consider that the Java-Plugin and the Webstart puligin are about the same size it's just a matter of weighing up who your target clients are and whats easiest.

Need to monitor event ID with Event Level :Critical , Also how to generate (powershell or otherwise) an event with Event Level :Critical

Need to monitor event ID with Event Level :Critical , Also how to generate (powershell or otherwise) an event with Event Level :Critical

Hi
First, we Need to clarify what do you want.
1) You want to Monitor a Windows Event with the severity "Error" (there is no Critical for Windows Events, only Error").
2) You want to create an Event in SCOM. I think you if you talk about "Event" in SCOM you mean actually an Alert.
There is no direct way like a tool/powershell script of only creating an Alert in SCOM only if you are going to use the SCOM SDK
http://msdn.microsoft.com/en-us/library/hh329086.aspx or using the Orchestrator Create Alert activity.
If you want to create a SCOM alert depending on a Windows Event you either can create a rule
http://technet.microsoft.com/en-us/library/ff730470.aspx or a Monitor

Generating Event with Subvi Control on Main Vi

We are creating a code in which on pressing set up button( present on main vi front panel ) we are calling one subvi as pop up window which further contains some boolean controls and every boolean control has further one subvi associated with it, when we press on that button a window comes that has several numeric and string control, what we want is after entering all values on numeric and string control and after pressing ok button, these val;ues should get updated to the sequence list present on main vi front panel, i have tried to do this using queue but what we want is that on pressing ok button( present inside subvi) we need to generate a event on main vi that it should dequeue elements to the list only when that ok button is pressed, i have tried to do it using value signalling property node but this is not working, i am not getting how to do this or there if there is any other better way to do this
I have attached the code for reference.

A better way to do this would be to enqueue the state that the event case is calling from the instrument state. Then you don't have to poll the global variable and worry about signaling the event.

Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

Error generating report job with the task name 'FSRM_Report_Task

Anybody have any ideas?

Hi,
From the error message, it failed because of "invalid argument: storagetype = '101' ".
101 means the storage type is "system" + "cache". Is there any change on your storage before the issue occurs? For example whether the source storage is changed?

How can I detect an external trigger and then generate an event or occurance

I have a PXIe-1065 chassis with a PXIe8030 controller, PXI-6653 timing module, PXI-6542 Digital IO, and PXI-6259 DAQ board, running LabView 8.5. I need to detect a trigger (100 ns TTL pulse) from an external device then start a process on a GPIB device. Is there a way for me to detect this trigger and then generate an event, or an occurance ? Can I do this without polling a device? Can any of this hardware generate an interrupt that LabView can detect?

My screenshot was only an example how you can approach the issue. I wasnt saying that you should try it with AI....
Just take a closer look into the DAQmx Events and you will discover something like this:

Programatically change control focus to generate and Event......

I'm adding some user enhancement (anti-screw-it-up functions) to insure the desired process is executed.
Primary question: If I have an event that is handles by a value change in a text control, (event happens when you hit Enter or exit control with mouse) will the event also occur if you exit the control by programatically changing the focus to another control ?
I'm going to try and set up a temp vi to test this but wanted to see if anyone had tried this and if it works or not. My other option is to set up multiple event cases but I was hoping to use a single case to handle everything.
A few details, I have a test system that tests a product automatically when the product is placed in a cradle and the cradle is moved into position and activates a prox sensor. At end of test, system waits for prox sensor to de-activate before resetting the system.
If a unit fails, there are rework options and the unit can be retested. When it fails, a label prints defining the failure modes and provides a failing serial number. When the unit is retested, the failing serial number is entered into a text control. I want the re-test sequence (queued up in the Event) to occur when either 1, a failing serial number is entered or two a button is pressed (with mouse) I'm pretty sure pressing a button would in turn automatically create the text control change event so my button can probably be a dummy button just for appearances.
Where the hole is if the user enters a failed serial # and doesn't exit the control and then engages a pump to start the test. I can use a 'Empty Path/String' function but the control will continue to show empty as if nothing was entered until the Enter key is pressed or the mouse is used to exit the control.
If I can generate the event by changing the focus, then it will insure that if a failing s/n is entered, the re-test sequence occurs and if nothing exists in that field, it performs a first time test.
A little long winded for sure but any thoughts are appreciated.
Can't really post any simple code as this feature is in my top level vi and I have a really big app that doesn't warrant uploading.

Solved!
Go to Solution.

Actually, changing the focus alone did not trigger the event but I was able to then utilize the Empty Path/String function to drive a Value(Signaling) node for the control.

INTERFACE AND EVENTS IN ABAP OO

Can some one explain me the real time need with example for use of interfaces and events in abap objects
(asking interface and events along doesnt mean that i am relating them).
<removed_by_moderator>

Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.

Why and how to use events in abap objects

Dear all,
Please explain me why and how to use events in abap objects with real time example

Hi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...

Events in ABAP runtime.

Can Any one explain me the events in ABAP runtime with proper example please.

Hi Srnivas,
Here are the events in order
Classical Report Events:
Initialization
At selection-screen
at selection-screen output
start-of-selection
end-of-selection
top-of-page
end-of-page
Interactive Report Events:
Above events and also,
at line-selection,
at user-command,
at pfn
The following events occur at runtime of a typical report program which uses logical databases:
Event keyword Event
INITIALIZATION Point before the selection screen
is displayed
When you start a program in which a selection screen is defined (either in the program itself or in the linked logical database program), the system normally processes this selection screen first. If you want to execute a processing block before the selection screen is processed, you can assign it to the event keyword INITIALIZATION.
AT SELECTION-SCREEN Point after processing user
input on the selection screen while the selection screen is still active
The event keyword AT SELECTION-SCREEN provides you with several possibilities to carry out processing blocks while the system is processing the selection screen.
START-OF-SELECTION Point after processing the selection screen
The event START-OF-SELECTION gives you the possibility of creating a processing block after processing the selection screen and before accessing database tables using a logical database. You can use this processing block, for example, to set the values of internal fields or to write informational statements onto the output screen.
At the START-OF-SELECTION event, also all statements are processed that are not attached to an event keyword except those that are written behind a FORM-ENDFORM block
GET <table> Point at which the logical database
offers a line of the database table <table>.
The most important event for report programs with an attached logical database is the moment at which the logical database program has read a line from a database table (see Accessing Data Using Logical Databases ). To start a processing block at this event, use the GET statement as follows:
Syntax
GET <table> FIELDS <list>.
After this statement, you can work with the current line of the database table <table>. The data is provided in the table work area <table>.
GET <table> LATE Point after processing all tables which
are hierarchically subordinate to the database table <table> in the structure of the logical database.
To start a processing block at the moment after the system has processed all database tables of a logical database that are hierarchically inferior to a specific database table, use the event keyword GET as follows:
Syntax
GET <table> LATE FIELDS <list>.
In analogy to report programs that use only SELECT statements (see table in Comparison of Access Methods ), the processing block of a GET <table> LATE statement would appear directly before the ENDSELECT statement in the SELECT loop for the database table <table>.
END-OF-SELECTION Point after processing all lines offered
by the logical database.
To define a processing block after the system has read and processed all database tables of a logical database, use the keyword END-OF-SELECTION.
The following events occur during the processing of the output list of a report program:
Event keyword Event
TOP-OF-PAGE Point during list processing when
a new page is started
END-OF-PAGE Point during list processing when a page
is ended
The following events occur during the display of the output list of a report program:
Event keyword Event
AT LINE-SELECTION Point at which the user selects a line
AT USER-COMMAND Point at which the user presses a function key or enters a command in the command field.
AT PF<nn> Point at which the user presses the
function key with the function code PF<n>
With the selection screen, ABAP/4 offers an interactive element also for report programs. You can define a selection screen without having to bother about all the details required in dialog programming.
The selection screen is always processed directly after a report program is started. The user can enter field values and selection criteria on this screen.
Reward points if useful.
Cheers,
Swamy Kunche

Responding to two user events with same name

LV 2013, Win 7, & LVRT 2013, PharLap OS
I have a situation where I create an ARRAY of User Events, one for each "domain" .
A "domain" is an area of DAQ: there is a SCXI domain, a CDAQ domain, an EtherCAT domain, several domains dealing with TCP instruments etc., about 25 domains all told. The name of the event is "New Channels This Domain".
When a new configuration comes to the PXI from the host, I sort out the channels by their domain and generate a user event for whichever domains have channels that have changed: more channels, fewer channels, differences. If a domain has no channels that have changed, I do not generate an event for it.
There is a handler for each domain: in that handler, I pick out the event for this domain from the array, and register to receive it. I have an event structure that responds to the NEW CHANNELS THIS DOMAIN event. Since it is an array, then no matter which domain I select, the name of the array is "New Channels This Domain".
All this works fine.
Now I have a situation where it makes sense to have one handler for TWO domains.
I can pick out TWO elements of the array just fine, and register them both. (See attached pic) But now, in the EDIT EVENTS FOR THIS CASE list, I have TWO events called "New Channels This Domain". I can select one for one case, and the other for the other case and it seems to work.
--- Is there any heartache ahead with this scheme?
--- If I change the events in the clusters before, is it going to confuse LabVIEW?
--- Is there something I can do to change the name of the event after I pick it out of the array?
--- Is there something I SHOULD do at that point?
Like I said, it seems to work, but I'm leery of it staying that way - I've had event structures disturbed before (LV2010) when changing cluster order.

Thanks, Greg for that link. I gave kudos to the idea of the COERCE TO TYPE function, and it seems like it would do the trick, but as of LV2014 it's still not on the palette.
My question still remains: is it necessary? Will the event structure remember that it's supposed to use the SECOND event named "X", through all edits and recompiles? My guess is no, but I'll listen to alternative stories.
I've been using the Coerce to type for this and enums in versions 2011 through 2014 since learning about it. I've seen no issue using it in these cases. I'm guessing it doesn't behave in an expected way for extreame uses which is why NI doesn't release it yet.
As for would it always know to go to the second event if they are named the same? My guess is yes. They maybe named the same but they have different references. I would think it would be just like having two controls with the same label. You should never do this, but if you did, and made a local variables on one and wrote to it, it would always write to the correct control. It would never write to the different control with the same name. Now even if this is the case it could be confusing to a developer looking at the code, which is why I strongly suggest having unique names. But if you don't I suspect every thing would work fine, just have a bold comment or something explaining what each case actually is handling.

How to use web service with ABAP Web Dynpro

Hi.
do you know, how to web service with ABAP Web Dynpro?

Hi,
If you have a webservice ready with you then you can generate a proxy from SE80 and you can use that. You just have to create a port and assign to that generated proxy(CLASS) and you are good to go.
Let me know if you need more information.
Thank You,
