Hi,
I Agree with all the comments.
Just to add - You can check, if the RFC is up well in advance before the call of your FM 'ZMB_EXTPR_SELECT'.
You can use the FM 'RFC_GET_SYSTEM_INFO' and check if the RFC is working fine..If RFC is not working fine then don't call the FM 'ZMB_EXTPR_SELECT'.

FPM: Error while creating component Configuration

Hi,
I have installed ABAP trial version (NSP), but without loopback adapter. So, now for every WebDynpro application, I have my manually change link from "http://<mymachineName>:8000" to "http://localhost:8000".
I create an application on FPM component: FPM_OIF_COMPONENT, then an application configuration for this application.
I open this Appl. config. in se80 and press "Start configuration". Now I try to create new component configuration.
After maintaining description and transport information, I save it.

Partner Profile vanishes in BW system

Hi All,
We are facing a recurring issue which happens in BW QA system after we refresh is from the BW production system.
After about a week or so after the refresh, the data loads halt in the BW QA system and the BW team gets an error "EDI partner profile not available".
After i checked, i found that the logical system name entry for the EDW QA system (i.e. self system entry) is missing from the table EDPP1 and also from transaction WE20.
I re-created it in WE20 and the entry automatically got created in EDPP1 table.
My question is : I suspect that some job or application program is deleting this entry. We checked the background jobs but no luck.
How do i resolve this error. The client has come up with this question and he wants an answer as to why this
entry is being automatically.
Can you please help?

R/3 Client Copy : Problem in BI.

Hi All,
Our Basis team have done the R/3 production copy to R/3 quality recently. These has created the problem in my BI development system.
We have a working BI development system which is connected to R/3 Quality as well as R/3 development and all standard data sources were succesfully implemented in BI dev from R/3 Quality previously.
After this Client coply i could not able to see any data source related to R/3 quality in my BI Dev system.
I have checked the RFC connection and it is OK.
I have checked the R/3 Quality also. All my CMOD routines have been removed.
I could not able to see data sources in RSA6 also.
As per my understanding this should not happen after client copy.
I do not want to retrasport all the tasks from R/3 dev to R/3 quality again.
Please suggest .
Regards,
Macwan James.

Hi,
Once you copy/refresh the R/3 Qty with R/3 Prod you loose all Transports and settings, you need to re-import the TRs from R/3 Dev to R/3 Qty. Before that you need to set all settings between BW qty and r/3 qty.

640 - No event raised for Infotype 19 (SWEHR1/2/3)

G'day all,
I'm trying to raise events when Infotype 0019 is inserted/changed/deleted.
I've had a poke through SWEHR1/2/3 to find similar entries. Most of the Person related infotypes are linked to Objects with an ultimate parent object of EMPLOYEEI. As such I've tried as an initial test to get the CREATED event of this object raised.
In SWEHR1 I've created an entry as follows:
Ob - P
IT - 0019
Obj.Type - EMPLOYEEI
In SWEHR3 I've created entries as follows:
Ob - P
IT - 0019
Updat - INS
Obj.Type - EMPLOYEEI
Event - CREATED
Ob - P
IT - 0019
Updat - UPD
Obj.Type - EMPLOYEEI
Event - CREATED
(This second update entry was simply to see if my problems were related purely to insertion.)
When I create a 0019 record for an employee no event is getting raised.
I've debugged through the Function HR_EVENT_CREATE while executing PA30 and in the end it calls SWE_EVENT_CREATE with everything looking fine. However no event is raised.
We are on 640 basis supp.pk 15 now. OSS note 904851 was found and applied while we were still on 14.
I can't find anything else on OSS, this forum or WUG that seems applicable.
There aren't any ST22 Dumps, RFC issues or System Log entries.
Can anyone shed light onto what I may be missing??
Many thanks,
Mark

G'day all,
Just a quick update. I received the following response from the MIT WUG which solved my issue. I've been waiting to see if I could get the same response from Alla here to be able to fully award points... oh well.
Have fun,
Mark
>>>>
You are right OSS note 904851 partially fixing the problem. It's required to have an active WF in order to publish an event.
We are having the same problem with HR events and I got a replay from SAP support.
Its an error in business workflow which has been corrected by the note no. 913330. Please implement it and the problem
should be solved."
I tested it and it's correcting the problem.
Thanks, Alla Ostrowsky.

BDLS Conversion after System Copy fails

Hi All,
We are doing a Homogeneous System Copy on a AIX 5.3/Oracle 10.2.0.4/ SAP ERP 6.0 environment.
After the system copy we had to run BDLS to convert logical system names in tables. Except for 3 tables namely EDPP1, TBD05 and TBD06 the BDLS run was successful.
We tried to convert the logical system names in these tables by running BDLS for these tables individually however they failed again.
The error was - "Error in field of table. Manual correction required"
I checked SAP Note 121163 and it is mentioned in this note -
"If the new logical system name already exists in the system, it can cause errors for tables in which the logical system is key field or
unique index (for example, COFIO1). In this case the number of converted entries is smaller than the number of selected entries."
And in this case a manual post-processing is required. How do I go about doing this manual post-processing?
1. Should I maintain these directly at the table level - which is cumbersome as there are a lot of entries?
2. Or using a small ABAP program?
Please let me know if any other information is required frommy side.
Thanks, Dibya

Hi,

BI System Copy of disconnected systems

I am SAP BI person and need some suggestion regarding the BASIS expertise.
If I have two BI systems (Say BI-1 & BI-2). I do not have any transport path maintained nor any connection between these two servers.
If I develop some objects in BI-1 system, can I copy to BI-2 system using some mechanism or custom software. I can also go with the system copy.
Here I have two questions:
1. If both the systems are running on different OS platform
2. If both the systems are running on same OS Platform
What would be the possibility in above mentioned cases? Can I copy the system or objects?
- Danny

Hi,
Here I have two questions:
1. If both the systems are running on different OS platform
Transport it, else copy the CoFiles and DataFiles from B1 to B2 and try
2. If both the systems are running on same OS Platform
What would be the possibility in above mentioned cases? Can I copy the system or objects?
If your Basis team is strong you can do it.So you need basis help.

BDLS - Client Independent Table

Hi All,
When I execute BDLS, there are two options there, one is conversion of client dependent and independent tables and the second is conversion of client dependent only.
In a BW system, what are the differences of these two options and which one should be used after system copy ?
I can't understand from the standard documentations provided.
Please share. Thanks.

After system copy

Hello
I have connected my Productive BW 7 system with a 3rd party DB.
After the basis perform a system copy from Productive BW to Quality BW are there
any after copy activities to refresh also the connections and the datasources for this connection to point to the
3rd party quality DB?
I mean for ABAP system we can perform through transaction bdls etc. some after copy activities.
Are there similar activities between BW and DB connect systems.
Thank in advance..

ABAP Dump due to RFC Function module call in another thread

Hi,
I am facing some problem since yesterday. In one of my executable program I am calling a RFC fm as below mentioned
REPORT ZREPORT.
CALL FUNCTION 'Z_XXXXXXXXX'
      STARTING NEW TASK L_NAME
      DESTINATION IN GROUP 'TASK'
      PERFORMING RETURN_INFO ON END OF TASK
      EXPORTING
        P_exp1       = l_emp
      TABLES
        R_VBELN      = r_it_vbeln
      EXCEPTIONS
        NO_DATA_TO_PROCESS = 1
        OTHERS             = 2.
wait until v_task = 1.
update ztable.
Due to some data inconsistence one of the SAP function
module which I am calling in my function module Z_XXXXXXXXX
is generating dump with message type X. Since there is data inconsistence it is generating dump that's OK.
But the problem i am getting is, report ZREPORT is generating dump at WAIT statement saying illegal statement even though I am calling that function module
Z_XXXXXXXXX as a separate new task.
Can somebody help me.
Thanks,
Amara.

hi, Amara
I agree with Rich said, and do a simulate test in my server, here is the analysis.
Assume we have a RFC, like this:
FUNCTION ZGZL_DUMPTEST.
*"*"Local interface:
*" EXPORTING
*"     VALUE(OUT) TYPE I
*" EXCEPTIONS
*"      CONVERT_FAIL
data:a type i.
a = 'A'.
ENDFUNCTION.
And call this RFC like you way:
REPORT ZGZL_DUMPTEST .
DATA:
SEMAPHORE(1) VALUE SPACE,
LC_OUT       TYPE I.
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
if we run the RFC in se37 directly, obviously it will occur a rumtime error CONVT_NO_NUMBER, and dump.
But if we run the above application to call the RFC, we will get a different runtime error CALL_FUNCTION_REMOTE_ERROR.
Error Analysis in ST22 like this:
An error occurred when executing a REMOTE FUNCTION CALL.
It was logged under the name "CONVT_NO_NUMBER"
on the called page.
I think that means the application receive the runtime error from RFC when call <b>RECEIVE RESULTS</b>.
In normal CALL FUNCTION, the external application will accept the rumetime error throw from FM, that's correct, because it let the caller can handle these runtime errors.
In you case, you said RFC run in a new task, yes, that's true, so you can call the RFC like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
It will goes well, no dump. Why? because we don't use RECEIVE RESULT. RECEIVE RESULT will bring the result from FM, also bring the runtime error from FM.
So if you want to call the FM and receive the result, handle the runtime error in FM inside at first.
like this:
CATCH SYSTEM-EXCEPTIONS CONVT_NO_NUMBER = 1.
    a = 'A'.
ENDCATCH.
IF SY-SUBRC = 1.
    RAISE CONVERT_FAIL.
ENDIF.
And then you call FM like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT
          EXCEPTIONS CONVERT_FAIL = 1.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
That's will be ok for your scenario.
Hope my reply is useful.
thanks

Hi,
possible solution could be a ConversionException in you RFC Adapter because of mismatching data types in your source and receiver message.
Just goto RWB an monitor the Processing Details for Cluster Node Server of your adapter in the Channel Monitoring.
Afterwards you have to adjust your importing or exporting structure of the used RFC function module.
Cheers,
André
