Subcontracting with Error Handling

Dear All,
we have some subcontracting materials. If the warehouse do the good reciept and the one of the components is not at the subcontractor stock they get an error.
Now they came up with the question if it is possible that this materials went to the COGI and once a week they solve this problems.
kind regards,
Bernhard

Hi Bernhard,
COGI is not enabled for this situation, and the reason I can think of is that the system is calculating online realtime the moving average price of the received material, by summing up the costs of the issued materials. Therefore the information on which and how much of the components were issued must exist at the time of receipt, and cannot be later processed like in COGI.
I know this doesn't help with your problem, but at least now you can better explain to your users why the stock must be accurate.
Regards,
Mario

BPM with error handling

Hi,
I have a BPM scenario as follows,
Receive input file thru HTTP protocol
Send it to SAP thru sync XI protocol
Response from SAP has a field with status code
If the code says its success, then send response back to 3rd party and place the input file in archive dierectory.
If the code says its failed, then send an email with error description and plance the input file in error directory.
I would like to have a breif hint on the step-wise process flow in BPM technically.
Thanks,
Karthik

Thank you all.
I would like to follow the solution suggested by Tarang Shah as below
1. Receive step to receive the HTTP request
2. sync send to send the data to SAP and get the response back
3. then the switch where
if status = 'OK' then
1.async send --- to send rseponse to the directory u want
2.async send ---here the message will be the one specified in step 1 which will go into Archive
otherwise
1.async send --- to send the mail using mail adapter
2.async send ---here the message will be the one specified in step 1 which will go
into ERROR folder
Now my question is 'Do we need correlation in this case or will the refMessageID in the SAP response be internally correlated to MessageID of the request message in step 1?'
Please clarify.
Thanks,
Karthik

Powershell 4.0: Problem with error handling inside Eventhandlers - Powershell has stopped working

Hallo!
Please see the attached sample code. This code simply show a small WPF-Dialog.
Test 1 (showing the problem)
Simply run the program. You will see Powershell crashing "Powershell has stopped working".
The cause of this is the devision by 0 inside the Eventhandler.
We would normally expect, that the exception should be handled by the trap.
Test 2 (showing normal operation)
Simply remove the comment in line 28 ($i=1/0).
This activates an exception outside the Eventhandler. Now the Trap will be executed normally.
--> The exception can be handled by the Powershell Devloper.
Can anybody help? Why does the Error management via Trap not work inside Eventhandlers?
Thanks for some assistance and ideas!
Regards
Heike

Mastermind / Parse string with error handling ....

Ok I am not going to hide the fact this looks like a homework question, honestly I already handed it in and now this is bothering me that I couldn't figure it out.......
We had to make a mastermind client/server game only using text no graphical everything runs fine but how would one do error catching on this. (code posted below)
Basically the user types in the command "guess r r r r" (guessing that the secret code is red four times ) and it parses it and assigns guess[] with the r and checks it based on the randomly generated color. The problem that I have is that is if someone makes a typo for example guess r rr r. How would one stop it from crashing from an out of bounds array request?
if (command.matches("guess.*"))
                           int white = 0;
                           int black = 0;
                           String phrase = command;
                           String delims = "[ ]+";
                           String[] guess = { null, null, null, null, null, null, null };
                           guess = phrase.split(delims);
                           for (int i = 0; i < 4; i++)
                                if (color.equalsIgnoreCase(guess[i+1]))
                         black++;
                    else if (color[i].equalsIgnoreCase(guess[i+1]))
                         white++;
                    else if (color[i].equalsIgnoreCase(guess[i+1]))
                         white++;
                    else if (color[i].equalsIgnoreCase(guess[i+1]))
                         white++;
               if (black == 4)
                    anwser = "You WIN!!!!!!!! KIRBY DOES A SPECIAL DANCE FOR YOU \n (>'.')> (^'.'^) <('.'<) \n";
                    gamePlaying = false;
                    commandChecker = true;
               else
                    turn++;
                    commandChecker = true;
                    anwser = "You got " + black + " black and " + white + " white it is your " + turn + " turn \n";
               if (turn >= 10)
                    anwser = "You Lost =( , try again, the anwser was " + color[0] + color[1] + color[2] + color[3] + "\n";
                    gamePlaying = false;

if(guess.length!=4){

I should add that usually the best way of avoid array index out of bounds exceptions is to avoid ever hardcoding things like
for(int i=0;i<4;i++)The 4 there is dangerous.
It's safer to use the length
for(int i=0;i<guess.length;i++)And the same applies to List(s) and the size method. Again usually that's a better idea but in your specific case anything more or less than 4 is not only a looping problem it would cause logical errors in the rest of your code... it is an exceptional case and should be dealt with specifically in your code.

LabVIEW for Mapping of Network Drives with Error Handling

Is there a way to do the following easily in LabVIEW?
- List drive letters and network paths of existing mapped drives on host PC
- Check if a desired mapped drive is connected and if its disconnected reconnect to it
- Receive related errors that may occur during attempting a connection to a mapped drive (i.e. path cannot be found, etc...)
I know how to do most of this in VBScript but I'd like to avoid having ANY code for the work I'm doing be "non-G"!
Thanks for your time!

Error Handling in info-package strangely doesn't work

Dear All,
I'm trying to load master-data from R3 containing time-dependent attributes which, I know, are sometimes overlapping. As I still want to load the correct part of data, i've set Processing - via PSA and Error Handling - "Updating valid records, reporting possible" with number of errors more than the dataset itself. However, the load still fails and what is more interesting, all records in PSA are marked as "green" whereas the errors are reported in a log.
And what makes me wonder even more is that the same info-package from the same DS is loaded in a test system OK - with errors handled and "trashed" in PSA and remaining updated in Info-Object MD.
Does anybody can help to resolve this strange problem as i can't honestly see the difference in global settings of test and productive systems that could allow this...
Thank you in advance

Hi,
Here you are extracting data for master data with one of the attribute as time dependent . So there are two more fileds are neccessary in extraction ,i.e, 'from date' and 'to date'.
And it seems there is overlapping of this range for two records. Make sure it in PSA with record numbers. And make sure there will be no overlapping.
With rgds,
Anil Kumar Sharma .P

General Error handling

I've managed to get myself confused with error handling in Forms 6i.
If I have a trigger that does a 'commit-form' like this
commit_form;
IF NOT form_success THEN
RAISE form_trigger_failure;
END IF;
EXCEPTION
WHEN OTHERS THEN;
END;
and the commit_form fails due to a mandatory field being missing (or similar) then what happens first?
Does my ON-ERROR trigger fire?
Does the form_success check fail and raise form_trigger failure?
Does my exception block get used?
Or does more than 1 happen??
I could - of course - find the answer to this through debug but I'm looking for a more generic answer if possible.
Thanks - Sean.

What happens first? The forms validation process runs and informs user that the field is required.
Does On-Error fire? Yes, if you have one in your form.
Does the form_success check fail and raise form_trigger failure? Yes -- but ONLY if your On-error raises Form_trigger_failure. If it does not, you have lots of problems.
Does my exception block get used? Yes. Raising Form_trigger_failure causes control to pass to the exception handler. But I never use an exception handler except when I code SQL commands.
Now... After commit_form, you should also check Form_Status. Read the help topic on the Form_Success built-in.
My standard C00_Commit program unit does this:
COMMIT_FORM;
IF :SYSTEM.FORM_STATUS <> 'QUERY'
OR NOT FORM_SUCCESS THEN
RAISE FORM_TRIGGER_FAILURE;
END IF;
END;

Error Handling: VI response to any error

Hey guys,
I need to make sure a piece of code executes whenever there is any error in the VI. I'm pretty new to Labview, and cannot wrap my head around "extracting" the errors, so I can pass them into an error handler... All I want, is for my code to find out that there is an error, take some action, and then stop execution.
Any help is greatly appreciated, thanks!
Solved!
Go to Solution.

You simply wire the error wire to the selector of a case structure. Click on file/new/from template/frameworks/SubVI with Error Handling

How to handle BEA-382108 error in route error handler?

Hi,
I have a proxy service with error handler at route level. when any wrong inputs are given to this proxy the Biz will generate fault with error as BEA-382108
having error message as XPATH can only be done for XML or MFL content. This is error is handled by system error handler but not by route error handler.
Can any tell me how to handle this error in route error handler...?

In route Error Handler.
Add If condition and add fn:contains($fault,"BEA-382108") in the if condition, and add your code/logic that you want to implement in case of this error in IF condiiton.
Let me know if this helps.

Karan

Subvi dll error handling

Hi everyone
I have a basic/principal question regarding subvi's and associated error handling.
Say I have an DLL which contains a function that takes input a and b, outputs c and d and that I want to wrap this function call (plus additional logic) into a SubVI. I can imagine this done in two ways with error handling:
Which one is the most "correct" (or pretty or smart) way to do it?
Best regards
Wuhtzu

First off, I agree with nathand that you do not need the case structure (the Call Library Function Node handles it).
Second, if you are wrapping DLL functions, take a look at the import DLL tool. (Tools->Import->Shared Library in the menus). It will create wrappers for your DLL functions -- then you just have to test them and make some tweaks
For example, if you have a parameter which is a pointer, the tool will make you an input and an output (since it can't tell which it is meant to be, and might be both). Often you really just want it as an input or just as an output, so you have to change that (and make sure, if an output, that you have someplace to put it; in some cases you will need to make a constant of that type and pass it into the Call Library Function node, and then pass it out.
I have had a lot of success using this tool, and it saves a lot of repetetive grunt work.

Report and Alert don't executed in the error handler with a JMS proxy service

Hi,
I'm working with OSB 11.1.1.4.0 and I'm facing a problem with the error handler of my JMS proxy service.
My error handler contains two main elements :
- a Report action
- an Alert with a JMS destination defined
When the business service failed the message remain in the queue. It's the expected behavior.
The problem is :
- the report is missing
- the alert is raised but missing in the JMS destination defined in the Alert setting.
I've noticed if I add a Reply with Failure or Success, Report and Alert are successfully executed.
Unfortunately the message don't remain in the JMS queue.
What can I do in order to have my report/alert done and the JMS transaction rollback in order to keep the message in the queue ?
I've already met this problem in the past with alsb v3 and my solution was to add Service Callout in the error handler in order to externalize these actions.
This solution is not convenient and I hope another solution is possible.

Inventorying workgroups can be difficult, especially when it comes to remote access and network security. Because workgroups are not centrally managed, some of the items discussed in this
wiki article on preparing your workgroup environment may require you to visit each machine individually.
For non-domain credentials, you do not use the <systemname>\<user> format, you simply enter the user name. Regarding how to enter the credentials, if you have an account that uses the same username and password on all machines and is an administrator
on all of those machines, then you can enter that in the All computers credentials page of the wizard. You can also do this if they are different user names. However, if some machines have an account with the same user name, such as Administrator,
but different passwords on each machine, you will need to use the Manually enter computer names discovery method, and then enter the information for each group or each machine.
As you can tell, workgroup environments can quickly negate any benefit that the agentless inventory nature of MAP provides.

LV7.1 Strange behavior with Automatic Error Handling occuring when it shouldn't [LV 7.1 Pro on WinXP for Tablet PC's]

[LV 7.1 Pro on WinXP for Tablet PC's]
I recently let a rather large LV app of mine run in the development environment while I was out for a couple of days. Upon returning I found that the app had hung for ~22 hours waiting for an answer to an Automatic Error Handling (AEH) dialog proclaiming an Error 7 in New File without any indication of the VI hierarchy that called New File. I set about ensuring that AEH dialogs would not pop up and have not been able to discover how I could have possibly received one in the first place.
Subsequent investigation revealed:
Neither AEH option in Options>Block Diagrams were checked.
Network problems had occurred around the time that the app had hung. All file paths are network paths when running in the development environment, so the cause of the error was most likely valid, even if the AEH dialog appearance wasn't.
My app has only one instance where the New File primitive is used by me. That subVI and all others above it in the hierarchy DO NOT have the AEH property enabled. The error out cluster of New File in my subvi is wired.
My app has three instances where New File is called from a vi.lib vi (Open/Create/Replace File.vi, Open Config Data.vi, and Prompt Web Browser Path.vi), none of which have the AEH property enabled. Nor does any of their calling VI's. All three instances also have their error out cluster wired.
A utility to examine the AEH property of all VI's (with all top level and dynamic VI's loaded) in memory reported that only 1 of 308 vi's ( RGT Does File Exists.vi from the Report Generation Toolkit) had that property true. That vi has no subVI's other than the File/Directory Info primitive and no calling VI's in common with any of the vi's that call New File, except a top level VI.
As long as 'Enable automatic error handling dialogs' remains unselected in options>block diagram, I am unable to get an AEH dialog for either the New File or File/Directory Info primitives in a test VI with AEH property enabled and their error out clusters unwired no matter what invalid path I pass to the functions. As soon as the options>block diagram>Enable AEH dialogs' is selected, both primitives fire AEH dialogs with no error out wired and don't when wired. i.e. works as advertised.
In other words I can find no reason why I should have gotten the problem AEH dialog...
I cannot afford for this app to hang because of a network problem, other portions of the app that were running concurrently correctly handled the error and, had the AEH dialog not appeared, the app would have made corrections or shutdown in an orderly fashion.
Any ideas?

Very good.
Write Characters to File.vi>Open/Create/Replace File.vi>New File
New File throws the error. Open/Create/Replace strips the hierarchy from the source of the error. Write Characters passes it to the General Error Handler. I never looked above O/C/R file in the hierarchy except for enable automatic error handling property. The tip-off should have been to realize that O/C/R file was stripping the hierarchy from the error and look above that.
The real irony is that Write Characters was being used to log error cluster data to an error log file...
Save as... Copy without updating... the OEM 'Write Characters to File' is gone from this app.
Thanx (a bunch)

Issue with SRDemo error handling

Hi All,
Glad the forums are back up and running. In debugging some error-handling issues in our own application, I found an issue in the error handling code of SRDemo. I thought I'd post the issue here, as many of us (myself included) use some SRDemo code as the basis for our own applications.
The issue can be found in the oracle.srdemo.view.frameworkExt.SRDemoPageLifecycle class, specifically in the translateExceptionToFacesErrors method. I'll show the code that has the issue first, and explain the issue afterwards:
        if (numAttr > 0) {
            Iterator i = attributeErrors.keySet().iterator();
            while (i.hasNext()) {
                String attrNameKey = (String)i.next();
                 * Only add the error to show to the user if it was related
                 * to a field they can see on the screen. We accomplish this
                 * by checking whether there is a control binding in the current
                 * binding container by the same name as the attribute with
                 * the related exception that was reported.
                ControlBinding cb =
                    ADFUtils.findControlBinding(bc, attrNameKey);
                if (cb != null) {
                    String msg = (String)attributeErrors.get(attrNameKey);
                    if (cb instanceof JUCtrlAttrsBinding) {
                        attrNameKey = ((JUCtrlAttrsBinding)cb).getLabel();
                    JSFUtils.addFacesErrorMessage(attrNameKey, msg);
            }Now, this bit of code attempts to be "smart" and only show error messages relating to attributes if those attributes are in fact displayed on the screen. It does so by using a utility method to find a control binding for the attribute name. There are two issues with this code, one obvious, and one that is a bit more subtle.
The obvious issue: if there is a binding in the page definition, it doesn't necessarily mean that the attribute is shown on the screen. It's a good approximation, but not exact.
The other issue is more subtle, and led to errors being "eaten," or not shown, in our application. The issue comes if you are using an af:table to display and update your data. In that case, the findControlBinding will not find anything for that attribute, since the attribute is contained within a table binding.
Just posting this as a word to the wary.
Best,
john

somehow, this message got in the wrong thread....
Hi Frank,
Yes, I simply scripted it out this way to contrast the behaviour if the first attribute was read-only vs not read-only. I found the issue on a page in our app that was simply drag-and-drop the VO from the data control on the page.
It's quite annoying, because our particular use case that hit this error is a "save" button on the page. If the commit operation doesn't return any errors (and it doesn't in this use case!), we add a JSF message saying "save successful" - then the attribute errors are further added later in the page lifecycle, so we get 3 messages: "Save successful" and "Fix this error" and "Tried to set read-only attribute" - quite confusing to the end-user when the only message they should see is "fix this error."
At any rate, the fix is to simply re-order the attributes in the page definition - that doesn't affect the UI at all, other than to fix this issue.
John
it was supposed to be something like:
Hi Frank,
Thanks for the reply. I was simply posting this here so that people who use the SRDemo application techniques as a basis for developing the same functionality in their own apps (like me) can be aware of the issue, and avoid lots of head-scratching to figure out "what happened to the error message?"
