[CATS] Exit CATS0002 and message handling

Hi,
In CATS regular (CATS Web Dynpro), I implemented CATS0002 for defining values when the user does not fill them himself/herself and I able to do it fine!
My requirements are to dispay a warning message that the system had to do so (because in some circumstances, it is a mandatory field) but I cannot manage to display that message because CATS0002 has not MESSAGES output parameter.
Messages should be displayed if the user is still on the first screen (Input) or has already navigated to the second screen (Review).
I tried to :
- call FM 'MESSAGE_STORE'
- use some MEMORY ID to transfer the informations to CATS0003 where there is a MESSAGES output parameter but this is really cumbersome since the user is able to do roundtrips between screen "Input" and screen "Review". Besides, as I corrected the entry, I am not able to (easily) determine where it appeared in the first place.
Thanks in advance for your help.
Best regards,
Guillaume

Hi Andrea.
I am not sure if this is what you are looking for:
http://help.sap.com/saphelp_nw04/helpdata/en/82/04b340be3dff5fe10000000a155106/content.htm
Seems that there is a JavaScript Library for Portal.
In WebDynpro events are triggered as described here:

Tool Pallete - Advanced - Message Handling Script/Script

We have few clarifications in OEDQ.
Tool Pallete -> Advanced -> Message Handling Script/Script:
we can write Java Script to define processing logic that acts across all the records in a message, or that acts selectively on only the first record in the message.
I tried writing Java Script for Data Validation and to display the message.
Java Code:
Public static void main(String[] args)
int EMPNO;
if(EMPNO = "123456")
system.out.println("Invalid EMPNO");
else
system.out.println("Valid EMPNO");
When we try to run the processor, We are getting the below error.
"error during process preparation
error in script: Error compiling Script: Missing ; before statement"
We are not getting error when we try to write a C program for the Message Handling Script.
C program:
var res=' '
var res1=' '
var res2=' '
if(input1=='US'){
res='Valid Country Code';
output1=res;
else if (input1=='UK')
res1='Valid Country Code';
output1=res1;
else
res2='InValid Country Code';
output1=res2;
Could you please let us know whether Java code can be used in Message handling script and can we have the header "Public static void main(String[] args)" in the script.
Thanks for your time.

Hi,
See the OEDQ online help here
Search for "Script" and "Message Handling Script"
You can use JavaScript or Groovy but NOT Java. Also the script needs to adhere to certain interfaces to allow it to be called by EDQ. See the examples provided.

I have created a customer exit variable and keep getting yellow message

I've created a Cusomter exit varialbe and when I run the query I keep getting this to pop up.
initial range-sign for cusomter exit variable timezone is corect
initial range-opt for cusomter exit variable timezone is corect

Hi Immich,
there might be the case in your customer exit where you are setting the variable value to blank.
for e.g.
cust_name = ' '.
where cust_name is your variable that ur filling up using the customer exit, instead of setting it to blank set its value to '#'.
i.e.
cust_name = '#'.
It will work fine and you will not get this message any more.
Hope this helps to you, and correct me if my understanding is not right.
Thanks

User Exit CATS0002 Validation

Hi Gurus,
I need to validate a field in cat2 transaction for a field . if the user enters a value other 1 then i need to validate that field providing an warning message "Number of days should not exceed 1 for a given date".
and then user should input the proper value (i.e, 1).
I incorporated this validation in User Exit CATS0002 CATS: Supplement recorded data.
in which i need did the validation for enrich_table-catsquantity as mentioned below.
IF enrich_table-catsquantity > 1.
      MESSAGE w667(lr) WITH 'No.of days'
                            'should not'
                            'exceed 1 for'
                            'a given date'.
       ENDIF.
1. If this condition becomes true the message will be triggred. then after executing this message staement will it alow the user to enter proper value ?
2. any other method of validating ?
Please help regarding this.
Thanks
ramu

Hi Kiran,
This sounds very interesting to me and I would like to learn more about the use case.
But first I need more information about your system landscape.
Do you run the use case on NW 70 EhP 1 or 2?
I strongly recommend NW 7.0 EhP 2 and I am convinced you get it done easily with BRFplus.
Calling BRFplus rules can be achieved by RFC or WebService call or locally in ABAP. Maybe take a look at a package called SFDT_DEMO_OBJECTS.

Receiver AS2 Adapter : Empty Message Handling

Hello Experts ,
We are trying to work on following requirement .
File -> PI -> AS2 ( File) ( We are using Pranke to drop our message to the receiver system) (MDN ack too is in place )
There are times when none of the source records are valid and we have an empty payload post mapping.
In AS2 adapter we are using StrictXML2Plain.
Scenario works fine for all target messages which have data and a file is created at the receiver end. MDN ACK works fine too.
Problem is when we have empty target payloads , We get following error in communication Channel monitoring.
Information
SEEBURGER/AttribMapper: Finished succesfully, 1 properties set or deleted

Message entered AF MP exit bean and will be passed to the JCA adapter now.

Has anyone handled such situation ? Is there any workaround at the SAP end to handle this issue ?
Or is this to be handled at the Pranke end ?
Attaching the Seeburger AS2 monitor error as well for empty messages ,
State

Hi,
here is the my requirment one source -> two target interfacess (0..1)
If u have 2 target interfaces,then this is not suffice..... u should make it as 0..unbounded both in operation mapping and message mapping.
But based on ur requirements posted above i guess u have only one inbound interface at a time based on some conditions....
But,
<messages>
<messages1>
based on condition first message type not created in mapping.
<messgaes2>
The error u r getting is because.... u want only one interface in target at a time....
Then u should not generate Message1 also in the target.
So avoid mapping to message1 if u want only message2.
If both message1 and message2 are created in target means... it is triggering for two interfaces.... so avoid one message1 or message2... based on some conditions u have..
Still nt solved do post...

JMS paging store - what is difference between bytes and messages threshholds?

          You can activate and configure both "bytes paging" and "message paging". What
          is the difference? Why use one or the other or are both required?
          Thanks,
          John


Hi Mr. Black,
          Cool name.
          Message paging is based on number of messages. Bytes paging is based
          on the size of message payload (properties, body, corr-id, and type),
          where the payload does not include the header size. One can set
          either or both -- if both are set, paging kicks in as soon
          as the first threshhold is reached.
          As for which one to use, you may wish to set both. The former
          accounts for large numbers of small messages, and the latter
          handles large messages. (eg 1000 small 10 byte messages
          will charge 10,000 bytes toward quota but actually use up
          128,000 bytes of JVM memory once the header is thrown in...)

I exited iMovie and lost my project. I am able to find it in Finder, under the Movies tab, but can not get it back to a project in iMovie. Is there a way to restore it?

Please help! I exited iMovie and lost my project that I've been working on for days... I am able to find it in "Finder" under iMovie Projects... but I am unable to open it as a Project in iMovie. I am using iMovie '11, with no time machine, and I'm on a MacBook Pro.

I fully sympathise with you, as I recently experienced the same issue (as have many others).
Projects always appear as normal in Finder in the Home folder Movies/iMovie Projects (or on an external disk at the top level in Movies/iMovie Projects). Nothing looks untoward there.
However, when iMovie is opened again after an editing session, the most recent project worked on does not appear in the listing of projects in iMovie's Project Library - although it is still listed in the Finder folder . This happens for no apparent reason - no unexpected quits, freezes, or crashes, and nothing else out of the ordinary. iMovie is simply not recognizing the project. It can't even be opened by double-clicking on the project in Finder.
Here are a number of links to other topics on this issue (there may be others I've missed):
https://discussions.apple.com/message/21370074#21370074

https://discussions.apple.com/message/21157079#21157079
Sorry to bombard you with all these links, but as you will see there are others here reporting the same problem. No solution has been forthcoming unfortunately.
Be sure to provide feedback to Apple - in iMovie's menu click on iMovie > Provide iMovie Feedback, then complete the online form.

Customer Exit Variable and Condition in a Query (Sequence of Execution)

Hi,
For a query i defined a Customer exit variable and a condition....
Which will first execute...wether it is a Variable and then Condition or vise versa
Is there any way we can control sequence of execution
My requirment is first to execute the condition and the variable how can i control this
Thanks

Hi
In your customer exit you will be having a field by name I_STEP which will help you to handle the time of execution of the variable.

Whenever you try to save a PDF file to a location other than the default location ('My Documents'), Firefox freezes & you have to go to the 'Task Manager' to exit Firefox and stop the error, so you can load Firefox again.

Whenever you try to save a PDF file to a location other than the default location ('My Documents'), Firefox freezes & you have to go to the 'Task Manager' to exit Firefox and stop the error. I have Windows XP (Media Center Edition) and all updates (Firefox, Adobe PDF, Microsoft, virus protection, etc) are installed. This has only been a problem since Firefox 4, and isn't a problem in Internet Explorer.

Hi David,
Thank you for your detailed question. It sounds like the real issue is pdf files. Are there any antivirus/firewalls that might be blocking this specific file type? or are there any preferences in your control panel that might be blocking this?
Do you have any stored preferences for PDF files in Firefox?

Receiver file adapter creates empty files, Empty-Message Handling SP19

Hello,
We have just upgraded the system to SP19.
One of the new features is that it should be possible to determine how XI messages with an empty main payload are to be handled in the receiver file adapter.
If the parameter Empty-Message Handling is set to 'Ignore' no file should be created if the main payload is empty. In our case an empty file (size 0 kb) is still created even though the main payload is empty and the flag is set to 'Ignore'.
Has anybody experienced the same problem?
// Best regards Hans

This should work:
Use your own adapter module that parses incoming message and checks if it has any record sets in the document. If it does not have any record sets, then set the message to empty and then give this modified message to File receiver.
For example, see the example code below:
Module imports..
Audit log import..
DOM imports/SAX imports..
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          try {
               // get the XI message from the environment
               Message msg = (Message) inputModuleData.getPrincipalData();
               AuditMessageKey amk = new AuditMessageKey(msg.getMessageId(),AuditDirection.INBOUND);
               Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"RemoveRootTag: Module called");
               XMLPayload payLoad = msg.getDocument();
               Document doc = parseXmlFile(payLoad.getInputStream());
               if(doc != null){
                    if(!doc.getDocumentElement().hasChildNodes()){
                         Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Document is empty!!");
                         payLoad.setContent("".getBytes());
                         msg.setDocument(payLoad);
               // provide the XI message for returning
               inputModuleData.setPrincipalData(msg);
               } catch (Exception e) {
               // raise exception, when an error occurred
               ModuleException me = new ModuleException(e);
               throw me;
               // return XI message
          return inputModuleData;
     private Document parseXmlFile(InputStream xmlpayload) {
          try {
               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
               factory.setValidating(false);
               //        Create the builder and parse the file
               Document doc = factory.newDocumentBuilder().parse(xmlpayload);
               return doc;
          } catch (SAXException e) {
          } catch (ParserConfigurationException e) {
          } catch(IOException e){

Hi,
Reprocessing IDocs with errors
Outbound (BD88)
Once the error has been determined and corrected it is not necessary to resend the IDoc again. You simply resend the IDocs that have already been generated.
Using the IDoc overview screen you need to take note of the following for each IDoc that was not processed:
Error number: 2, 4, 5, 25, 29
Error number: 30 (Execute Check IDoc dispatch to process)
IDoc number
Using the Error number, the IDoc number and the transaction BD88 , with the required message type you can resend the IDoc. Match the error number with this transaction and execute the function for the IDocs incorrectly processed.
Just check the below link, u will get all IDOC related Interview questions

Message handling with multiple lines to display

We have a requirement to issue an error message during dialog processing (PAI) and I'd like to use standard message handling if possible. The syntax
MESSAGE W008(ZTM) DISPLAY LIKE 'I'.
gives me a dialog box but handles the message as an error hence processing stops and the user returns to the screen. I want this functionality but with the ability to display several lines in the message pop up box. I've looked at the function modules POPUP_DISPLAY_MESSAGE but this displays only 1 line and POPUP_TO_CONFIRM which handles multiple lines but doesn't stop processing (unless further code is added to handle the response). Can someone suggest a standard of way of achieving this requirement or how to handle a response as an error in the subsequent processing after a call to function module POPUP_TO_CONFIRM.

hi,
you can handle like this.
call function 'POPUP_TO_CONFIRM'
