How to handle success/fail chains

I'm still getting the hang of this LabView programming style and have found a repeating (and annoying) design pattern that I'm sure others have encountered. I have a long series of steps to perform. Each step is a prerequisite of the next step and each could fail. So I've found myself creating these massive nested case structures so that step 2 only gets called if step 1 succeeds, step 3 only if step 2 is OK, etc. YUCK!
What is the Right Way to handle a chain like this?
Thanks,
Keith.

Vi's only begin executing when all their inputs are satisfied, right? Well, make use of that by paying attention to all the data your VIs can generate - or might need.
Say you have three VIs (A, B and C) that need to execute in the order listed. What information does A output that B would need? Regardless of exactly what A and B do there is one piece of information that will be there 90% of the time. I am speaking of status. A needs to let what comes after know whether an error occurred during its processing. Likewise B needs to know if an error occurred before it started.
The mechanism that LV provide for this status communications is the Error Cluster. It contains a boolean that serves as a basic error flag (T = error, F = no error); a numeric that can hold a general error code to specify in general what the problem is, and a string that you can put as much information as you want to identify the issue.
Stringing VIs together using the error clusters is an excellent way of structuring linear code - and can make your applications more robust. At least 90% of LV programs that appear to "lock-up" or "freeze" are due to errors that don't get reported.

How to handle delta failed process chain steps

Hi All,
I have a query regarding process chains were in processstep has delta load and there is dependency between the predeseccor and successor process steps,then
if the delta load fails due to any one of the following reasons
1) due to remote_icp locked the prtclr Infoobject the process step is executing .
2) due to any psa records errors and so on
Then how to handle delta and see that correct delta records were updated .
Because again for the nextday loads if the previous delta is incorrect it will give pop-up message that it is not possible.
If any suugestions pl guide me.
thanks

1)Remove the lock by force from sm12 or wait till the lock is gone.Then see if the delta data has come till the PSA.Mark failed delta load RED and back it out from target.Then read everything in manually from PSA to target.
In process chains u can go the monitor entry for the failed load by..highlight chain..click log icon..give selection..for proper selection..see the failed node..right click..display messages..click on process monitor.
Sometimes even if infopackage is run successful manually,next steps in the chain do not kick off.
Use Siggi's excellent blog on this..(it works really well)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
2)Make request RED and back it out from target.
Correct records in the PSA and read everything in manually from PSA to data target.
Then use Siggi's blog.
If data hasnt come to PSA do a delta repeat.
Always check yesterday's chain run about 1-2 hrs before today's chain kicks off.
cheers,

How to handle the failed records from the table when using DB Adapter

Hi,
I am reading some records from table using DB Adapter inside my synchronous BPEL process. Say like reading 100 records from table in between after successful reading of 90 records an error occured in 91st record due some various reasons(like DB down, Connection interrupted etc.). Then how to handle this situation, whether i have to read all the records from the begining and is there any option to continue from where it stopped reading.
Can please anybody help me out in the regard?
Thanks in advance
Regards,
Aejaz

we had the same requirement some time ago and had two option:
1. ask the R/3 development team add a deletion indicator in the table (and thus not actually deleting the record). this deletion indicator could then be used like for any other standard datasource
this option was however refused, due to huge data volume after a while
2. at the end of the load we copied the ZTABLE1 to ZTABLE2. then in the begin of the load (day after) we compare the data of table1 to table2. entries available in table2 but not in table1 are deleted, and we put a 'D'. in deletion indicator; as we only keep the deleted entries for one day, the volume of the new table is acceptable.

Hi
You will have to check if the Tax_Code of RMA being received is the same as the one in the related sales order.
If not you will need to use the same tax_code.

How to handle a failed transaction in Syclo Agentry SAP Work Manager 5.3

Hello Experts,
I have a transaction created on work order time entry.
For some reason, when the transactions fails (when clicked on transmit button), the transmit stops as soon as the error is thrown from ECC.
However, this transaction remains on the client and is not deleted.
when a new transaction is created on another object and transmitted, it still retains the previously failed transaction and tried to transmit it again.
Because of this, the transmit stops again and it fails.
Is there anyway to remove a transaction which has failed already? What is the best way to handle such scenario.
Thanks for the help!
Best,
Arihant Kothari

Arihant,
The Error handling within the application / editor does not have a one click type solution to just remove a pending transaction. As Jason mentioned the behavior is to stop when an error occurred so the user can correct and continue. In some cases this may mean removing the transaction through the removal of the associated object from the mobile device (clear option frequently) that when the object is cleared the associated transaction is also deleted allowing the pending transactions behind the current one to proceed.
The editor allows for error handling steps to be defined to execute upon error so that potentially you could log the transaction data off to the side for handling later and then continue processing. This of course requires there to be manual back office involvement monitoring the logged data for resolution and next steps.

Can you connect to a wifi source on the device? Enable wifi in settings on the device itself. If you don't have wifi at home, there may be a local hotspot you can use for this.
The reason this happens is carriers don't want people downloading huge files that would slow their network as well as eat up your data plan.

/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
Errors in monitoring of process chains can be categorized into 4 different sections...
Master data - Full Update
Master data - Delta Update
Transaction data - Full Update
Transaction data - Delta Update.. in terms of loading of data which can be due to server shut down or system maintenance... errors due to incorrect entries in the OLTP system in which case you'll have to fix the errors in the PSA and manually load the data...
Otherwise it can have errors on Attribute change run being locked by some other job... Aggregate Roll up failing because of attribute change run being run at the same time... Problem with hierarchies and save hierarchies...
There can be problems with the data store activation if the ODS object contains any incorrect request sitting inside it... then, you need to delete the incorrect request and reload the data again...
In case of Transaction Delta failure, you'll have to request for a repeat either manually in the infopackage or using the repeat option if available on right clicking the load event...
For Master Data Delta failures, you need to do an Re-init by deleteing the previous initalization condition in the "initalization option for source systems" in the menu scheduler or reschedule the enitre chain... because, master data generally do not support repeat of last delta ...

How to Handle SAP SUS XML Acknowledgment

Hi folks,
I have a scenario here where the SAP R/3 system sends a Purchase Order document to SAP SUS through a SAP XI Mapping.
After processing the P.O. document, the SAP SUS system, automatically, returns a Acknowledgment message (ns: http://sap.com/xi/XI/Message/30) to SAP XI.
I need to implement a BPM scenario where SAP XI processes this Acknowledgment message and Logs it into my Monitor System (JDBC Adapter). Actually, the SAP XI needs to send to my Monitor System the status (Success or Fail) of the P.O. processing by SAP SUS.
How can I handle this Acknowledgment message with a BPM Scenario? Is it possible?
Best Regards,
Nascimento

Hi Thiago,
Currently in BPM you can do this with ASYNC-SYNC Bridge design.
You can not dirrectly access the content of the ACK, however the BPM shows different behaviours based on the ACK status. E.g. if the ACK contains a success message the BPM will continue in its normal process, if the ACK contains a permanent error, it will either stop or go through an exception branch (provided such a branch has been defined). Have a look at the documentation: http://help.sap.com/saphelp_nw04/helpdata/en/43/65ce41ae343e2be10000000a1553f6/content.htm It doesnt"t state the above mentioned behaviour in detail but says that you need to define an exception branch.
The trickiest part is always to find out, when you will get a transient vs. as permanent error ack. If you are using ACKs with Proxies refer also to this link http://help.sap.com/saphelp_nw04/helpdata/en/29/345d3b7c32a527e10000000a114084/content.htm and this http://help.sap.com/saphelp_nw04/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/content.htm
Receiver adapters that run on the Adapter Engine support system acknowledgments if they are requested by the sender. Acknowledgements are triggered when a message is successfully processed by the adapter or if an error occurs while it is being processed. Receiver adapters do not support application acknowledgments. The RNIF and CIDX adapters are exceptions to this rule, since they also support scenario-dependent application acknowledgments. Sender adapters of the Adapter Engine do not request any acknowledgments.
However IDoc adapter is requesting application acks. Therefore you have to disable acks for this scenario using report IDX_NOALE.

How to handle stored procedure response having multiple queries

Hi Friends,
While working in JDBC to RFC scenario,I faced an issue that my stored procedure is having multiple SQL queries in it. First Select and then update and again some select options.So,how to handle the response of the stored procedure. I read that while using sender JDBC
" db.processDBSQLStatement=<SQL-Select-Statement>
Either specify a valid SQL SELECT statement to select the data to be sent from the specified database, or specify an SQL EXECUTE statement to execute a stored procedure that contains exactly one SELECT statement "
So, please suggest me is there any other way to catch the output of the stored procedure.Because, if select statement is working fine but if any other quires fails then data inconsistencies can happen.Kindly help me out.
Thanks and Regards,
Nutan

Hi nutan,
>>Already exception is handled in SP.But,issue is that select will never fail so, sender adapter will get the resultset from select and continue process.But if later any other query fails in SP adpter wont be getting any response.
Along with exception you need to handle the case when some other query fails. A SP is like a procedure which will do a certain list of activities before providing the output. So during this activity if some query fail then you can send back the response with a message!!!! And in XI handle this error (by routing it to some error receiver etc)
>>I need to try something like creating a temporary table and inserting the resultset of slect statement in that. and perform all other operations and after successful completion of all the queries.Again i want to get all the values from the temporary table. So,whether I can write such query in the sender communication channel.Please suggest me for this.
Approach looks ok, but think of the delay for JDBC sender adapter. IT will invoke your SP and will wait for it to fill a table and do all the processing. I guess this may become a issue for you.
Check on the frequency of this interface and message size before taking this design approach

How to handle empty Dats field received from SAP RFC response

Hi All,
I am invoking a SAP RFC which gives me a Dats field in response.
A valid dats fields is successfully received by my pipelines.
But when an empty Dats field is received, My pipeline fails and i get error.
How to handle the empty Dats field from SAP

Hi Anant,
This is because the legacy SAP adapter accepted RFC messages with date field empty. In the new version, the same call results in an error. WCF-SAP adapter doesn't allow blank XML nodes.
You need to use the below custom pipeline component as a workaround.
Refer:
Pipeline component for enabling legacy behavior in WCF-SAP adapter.

Now i want to debug ABAP step in Process chain which was completed successfully (This is Monthly load).
I have tried to debug the back ground job but it throws an error message in middle of the debugging.
Could you please tell me how to debug ABAP step in completed Process Chain.

1.Go to RSPC to view all the chains.
2.There click on any chain which you want to run/view.
3.Click on the log view(shift+F1) to view all the previous runs of the chain and whether they have failed or successful(here you can select 1 day,week ,month etc in the display range)
4.If you want to modify the chain /add a process type /change the variant then click (Ctrl+F9) and do the changes.
Even you can change the start variant in change mode for manual scheduling>right click on start process typeselect display variant--now select start Direct Scheduling/ API or Metachain
under direct scheuling option you can trigger it by setting start immediately /Date-time/After job/event whatever you want to do
Else you can make it part of a Metachain consisting of different such small local process chains.
Now Click on Schedule (F8) to run this chain manually.
5.For Monitoring use Tcodes SM37/RSPCM/SM50
Also you can use BWCCMS.
I usually prefer sm37 to view all the background jobs but SM50 is also useful.
6.debug loop can be used to debug a process chain.(you have to specify here the gap between one event been triggered and the next subsequent process starting)
to capture process in debugger go to SM37(job overview) or to SM50(process overview)
Hope this would help you.

How To Handle Error Message In TCD Recording?

Hi All,
I tried recording a transaction (my own transaction) by not enterring value in an obligatory field. the error message came. but when i executed the script, it showed an error. but actualy, the error message was expected right? how to handle this situation? i tried with tcd and sapgui recording. both gave almot the same result.
i am including the script which i have written.
MESSAGE ( MSG_1 ).
*TCD ( ZCUST , ZCUST_1 , ECC ).
SAPGUI ( SAP_1 , ECC ).
ENDMESSAGE ( E_MSG_1 ).
v_mno = &tfill.
v_msg = E_MSG_1[v_mno]-msgtext.
v_mtp = E_MSG_1[v_mno]-msgtyp.
If Msg Type is E *** **** It Has To Be E ****
IF ( v_mtp = 'E' and v_msg = 'Account no AC02 does not exist EXIT = X').
logtext(0,'Passed').
ELSE.
log(v_mtp).
log(v_msg).
logtext(1,'Failed').
ENDIF.
End Of The Condition For Message Type E ******

I have recording messages using the TCD command.
My script (very simple):
MESSAGE ( MSG_2 ).
TCD ( ME21 , ME21_1 , R3 ).
ENDMESSAGE ( E_MSG_2 ).
In the MESSAGE command interface, I defined rules to allow several kind of messages.
Execution: 3 mesages found:
      * transform PR into PO
       MESSAGE     MSG_2 [1,009 sec]
         RULES MSG_2 = XML-DATA-01
        Message MODE EXIT TYPE ID    NR
        [1]      'A'         'I'   06    456
        [2]      'A'         'W'   'ME' 080
        [3]      'A'         'E'   'ZE' 029
         TCD    ME21                 [0,545 sec N] Target sys R3 -> ZDA010A219
        S06017 Standard PO created under the number 8201075606
           Tgt System Z_A219->R3->ZDA010A219 (ZDA 010 ... HP-UX ORACLE)
           CALL TRANSACTION ME21 ME21_1 XML-DATA-01
           03 MESSAGES FROM ME21 ME21_1 XML-DATA-01
           I 06 456 Release effected with release code 00001
           W ME 080 Delivery date: next workday is 02.05.2007
           S 06 017 Standard PO created under the number 8201075606
       ENDMESSAGE E_MSG_2 (&TFILL = 0)
As you can see, 3 messages are found but the &TFILL variable is still 0.
I guess (but cannot test yet) I would manage to record those messages using SAPGUI command.
Is there anything wrong with my script?
My SAP_BASIS component is in version 620. I'm not using the ultimate version of eCATT (no WEBDYNPRO command, etc.). Could it be an explanation?
Thank you in advance,
Olivier

How to handle error message during PAI?

Hi Experts,
Need help here.
In my dialog screen, I have a field which is typed 'QUAN'.
In entering different format , e.g. with non numeric value or a negative value, an error message appear and it does not process the MODULES inside the chain or FIELD MODULE ON REQUEST.
Does anyone knows how to handle this kind of error. I need to display into a separate screen the errors I encountered coz I'm creating a new RF transaction.
Points will be rewarded.
Thanks in advance.

Hai
in your case(RF case) it is other way...
yes you can use
field x_currency module check_currency.
in module check_currency.
you have to display errors in another screen say 200.
in that there will be 4 fields, all are display only fields.
X_MESSAGE-MSGV1 of type sy-msgv1
X_MESSAGE-MSGV2 of type sy-msgv2
X_MESSAGE-MSGV3 of type sy-msgv3
X_MESSAGE-MSGV4 of type sy-msgv4
you populate the messages with these fields and then display it in the screen.
method check_currency.
*--do all your checks here....
       if error
         clear x_message.
        x_message-msgv1 = 'Enter Valid Employee Number'(004).
        leave to screen 0200.
      endif.
    endif.
ENDMODULE.                 " VALIDATE_Currency
in screen 200 PBO you need to format the message
using the below logic.
       Method for formatting the message
method message_format.
    data : lt_text type table of tline,         "text table
           lx_text type tline.                  "work area
    refresh lt_text.
    clear lx_text.
    concatenate x_message-msgv1 x_message-msgv2 into lx_text-tdline
      separated by space.
    append lx_text to lt_text.
    clear lx_text.
    concatenate x_message-msgv3 x_message-msgv4 into lx_text-tdline

How to handle the quotes('') in the procedure?

How to handle the plsql error occuring in the exception block

We know how to handle exceptins which occur in BEGIN block.
But am unable to catch the exception in the exception block. Am writing an erroeneous code so that the control will go to exception block and there is also one plsql error, but am unable to handle that error, it's returning the error to the calling environment.
DECLARE
cnt NUMBER(5):=0;
BEGIN
select 'debalina' INTO cnt from dual;
DBMS_OUTPUT.PUT_LINE(to_char(cnt));
EXCEPTION
WHEN invalid_number THEN
DBMS_OUTPUT.PUT_LINE('error has occured inside begin block');
cnt:='deba';
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('error has occured inside begin block');
END;
please suggest me how to catch this exception?

Hi,
DECLARE
cnt NUMBER(5):=0;
BEGIN
select 'debalina' INTO cnt from dual;
DBMS_OUTPUT.PUT_LINE(to_char(cnt));
EXCEPTION
WHEN invalid_number THEN
DBMS_OUTPUT.PUT_LINE('error has occured inside begin block');
cnt:='deba';
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('error has occured inside begin block');
END;
First of all your namee exception which you have posted i.e invalid_number itself is wrong.
You need to use named exception VALUE_ERROR for catching the exception in the main block.

2 cnt NUMBER(5):=0;

5 DBMS_OUTPUT.PUT_LINE(to_char(cnt));

8 DBMS_OUTPUT.PUT_LINE('error has occured inside main block');

error has occured inside main block
PL/SQL procedure successfully completed.Your doubt regarding catching the exception in exception block, you can execute as below, by nesting a Begin block inside the exception block itself.

14 End;
15 END;
