How to raise a exception if the incoming value for a source field is empty

Dear all,
I have a scenario where the source and target structures are as follows :
The output for the above transformation logic is
The occurrence for field id in source and target is 1:1 Even if i don't provide the input value for id field,
system is not throwing any runtime exception.But if the field tag id is missing in incoming payload, then
system throws exception.
1) *** How can i raise a exception it the value for field id is empty
2) As the target structure occurrence for field id is 1:1 why system doesn't throw exception for null value
Regards
Koti Reddy

1) *** How can i raise a exception it the value for field id is empty
You need to impliment the check to throw the error
2) As the target structure occurrence for field id is 1:1 why system doesn't throw exception for null value
You are sending a blank value " " and the same is being passed. if you remove the tag from source xml it'll throw the error

How to raise an exception in the badi

Hi friends..I've got the badi to be used for my object.Badi workorder_confirm
requirement is " if data is entered in one field leaving a field emprty,it should give an error message saying "Field is mandatory". I can make use of ERROR_WITH_MESSAGE exception for the message to be generated..
but dont know the syntax of it..please provide me with the statement how the message needs to be raised

Looking at the BAdI Documentation it says this:
Note that in the methods, no system messages may be sent. The only
exceptions are the AT_SAVE and AT_CANCEL_CHECK methods. Within these
methods, a system message may be issued, but only if you trigger the
exception ERROR_WITH_MESSAGE (for AT_SAVE method) or NOT_ALLOWED (for
AT_CANCEL_CHECK method) at the same time.
Note also, that within the methods the "commit work" instruction may not
be carried out because this would lead to incorrect data in the
database.
So the only thing you can do is use:
RAISE ERROR_WITH_MESSAGE.

Raising cx_rsrout_abort exception in Start Routine of Transformations

Hello Abap OO Gurus:
This is likely a very simple question but I'm brand new to Abap OO and despite reading and searching, I cannot convert some old abap code used in the start routine of business content in BW to be used in the Transformation start routine in SAP BI.
My Start Routine inside a BI 7.0 transformation rule has a method declared like this:
METHODS
start_routine
IMPORTING
request type rsrequest
datapackid type rsdatapid
EXPORTING
monitor type rstr_ty_t_monitors
CHANGING
SOURCE_PACKAGE type tyt_SC_1
RAISING
cx_rsrout_abort.
The Exception "cx_rsrout_abort" has replaced what used to be a simple ABORT data field. The old code I want to replace was just "abort = 1'.
But now it seems like I have to use TRY... ENDTRY statement to raise Exception "cx_rsrout_abort". I am inside the abap code of the Method "start routine"
METHOD start_routine.
*=== Segments ===
Could some kind soul educate me as to how to raise the Exception "cx_rsrout_abort" inside the Method start routine?
thanks in advance, David

Tx HDev:
we are almost there... I have that PDF but never got thru to the rest of the Appendix B as my project is just too crazy...
When try what Appenix B suggest..
"raise exception type CX_RSROUT_SKIP_RECORD."
I get the following Warning msg which makes sense...
"W:The exception CX_RSROUT_SKIP_RECORD is neither caught nor is it
declared in the RAISING clause of "START_ROUTINE".
The METHOD statement in the start routine never declares another exception other than cx_rsrout_abort as seen below:
 METHODS
 start_routine
 IMPORTING
 request type rsrequest
 datapackid type rsdatapid
 EXPORTING
 monitor type rstr_ty_t_monitors
 CHANGING
 SOURCE_PACKAGE type tyt_SC_1
 RAISING
 cx_rsrout_abort.
Maybe NW2004s has a bug here... I'm hoping that a SAP Developer reads this posting and can enlighten us all... otherwise I'll have to post a OSS msg
So the mystery is still how to do
"raise exception type CX_RSROUT_ABORT" and make this equal to ABORT = 1
which makes the start routine skip a record
tx again, David

How to handle message "Exception condition "CNHT_ERROR_PARAMETER" raised"?

Hi,
Whenever I try to open Web Dynpro Comp./Intf->Views using transaction SE80, I am getting a short dump showing message "Exception condition 'CNHT_ERROR_PARAMETER' raised'. In the analysis, I have found that A RAISE statement in the program "CL_GUI_HTML_VIEWER============CP" raised the exception condition "CNHT_ERROR_PARAMETER". Since the exception was not intercepted by a superior program, processing was terminated. Can anyone help to get rid of this problem?
Thanks & Regards.

hi,
Looks like, ITS services are not fully active or not compeltely published.

How to log the exception using Log action in Oracle Service Bus

Hi,
Whenever an exception is raised how to log the exception using Log action in oracle service bus.After logging where I have to find the logged message.

It would be in the log file for the managed server which ran the request. If you are logging the message at a lower level than your app server, however, you won't see it. You should be logging the exception at Error level.

How can we handle Exception Branch in BPM effectively

Hi,
I want to capture errors occurred in PM during runtime by using special "Exception Branch".
For example If i define exception branch for one black then any step within that block thrown error then automatically it calls that corresponding exception branch within that block. Now i want to identify which step within that block has thrown error and what is the error.How can i achieve this?
Thanks and Regards,
Sudhakara

Hi Sudhakara,
Generally we use control step to raise an exception, Please go through this link for better understanding:

How to write the exceptions in function module

dear all,
how to write the exceptions in function modules with example.
thanq
jyothi

Hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
· The RAISEstatement terminates the program and switches to debugging mode.
· The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*" IMPORTING
*" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*" EXPORTING
*" VALUE(ITAB) TYPE SPFLI_TAB
*" EXCEPTIONS
*" NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
wa LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
EXPORTING
id = carrier
IMPORTING
itab = jtab
EXCEPTIONS
not_found = 1
OTHERS = 2.
CASE sy-subrc.
WHEN 1.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Or
just have to decide what exceptions u want and under what conditions.
then declarethese exeptions under the exceptions tab.
in the source code of ur function module.
if
like this u can code .
now when u call the function module in tme mainprogram.
if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
in the fm u can program these sy-subrc values and trigger the code for ur exception.
Please reward if useful
Regards,
Ravi

BPM: How to Raise Alert and Restart together ?

The requirement is like this.My Integration Process receives a message, performs a 1:N split and undergoes further processing using Transformation steps. I want to ensure the following in case any one of the Transfofrmation fails(Because of some coding error in the step):
1. Raise an Alert
2. Should be able to restart the Process again from the
   failed step once the Transformation code is fixed.
3. To raise an Alert for any file adapter level errors,
   and to restart the processing of the message once the
   file adpter error is resolved
I have tried the following approaches, but it does not help me achieve all of the above condition.
I have put the Transformation step in a Block and introduced an exception branch with one control step which raises an Alert.
Issue: This will raise an alert when the step fails, but it ends the BPM with a Processed status and hence I will not be able to restart the BPM.
So I put another Control step immediately following the Alert step which raises an exception. However I have not handled this exception. Hence when a step fails, I am able to raise an alert as well as the BPM gets errored out.
Issue : However, now when I restart the process in swf_xi_swpr, The process restarts with the Control step which was used to throw exception. It does not restart with the Failed mapping step.
To raise Alerts for Adpter level errors which might occur before the message comes to BPM, I have defined alert category and rule in runtime workbench. However, the Alerts are not triggered when the file adapter fails.
Please share any ideas on how to achieve all the 3
requirements together.
Thanks in advance.

Hi Joachim!
I was facing a very similar problem in my BPM modelling.
Is there really no other chance than to loop (and maybe wait some time) over the critical (e.g. networking down, ...) parts of the BPM to have some active notification via alerts AND a possibility for retry?
In my opinion this would a very inflexible way of doing error-handling stuff - if so - is it about to change in the upcoming releases?
Currently I guess I can have:
a) either ALERTING (by catching exception and raise alert)
OR
b) convenient retry mechansisms via "SWF_XI_SWPR" (by not catching exceptions at all and let the relevant block become "errorenous") ...
Any other suggestions ...?
Many Thanks,
Andy
