JCO Exception in Background calling

Hi,
i am trying to upload data using sap standard uplaod programs throug a java application using JCO.
Unfortunately these standard programs sometimes pops up with a info message and i am getting these exceptions for Suppressing unwanted SAP GUI screens from BAPI/RFC when calling them from external system in background

i want to call these sap standard upload programs completely in backgroung through JCO.how can i do that??
how can i suppress info messages in standard programs when called externally???
any help will be appreciated...
thanks in advance

Hi Gregor,
The Messages i am getting i.e. "Session 1: Special character for 'empty field' is /" is one of the GUI information messages that the standard SAP uplaod program is popping.
i want to suppress these messages when calling them through an external system so that they can be called in background.
The standard program is using the batch input method.
Thanks and Regards
Berry

Hi Yolanda
Please refer the following links
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/f3f93ee7-0c01-0010-2593-d7c28b5377c2

Also which Patch level are you using for BI 7.0 . Your basis team should set the Integration of RSPLAN i,e web based planning modeller . Also hope you created the Input ready query correctly with Key figures having property set to Data can e changed using a planning function or by user.
Also check on WAD if you have configured the button group correctly to the planning function.
Hope this helps

RFC Adapter - JCO Exception - Please Urgent

I am developing a scenario from File--RFC integration. I am using File and RFC adapter to perform this transaction.
The File Adapter is picking the file properly and the trnaformation (Mapping Program) is also happening properly. But the RFC is throwing the following error. I got this error info from the Runtime Workbench.
Exception caught by adapter framework: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZPS_XI_ACTIVITY_CREATE in remote system (RfcClient[BAPI_CreateActivity_Receiver]):com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR
Error Delivery of the message to the application using connection AFW failed, due to: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZPS_XI_ACTIVITY_CREATE in remote system (RfcClient[BAPI_CreateActivity_Receiver]):com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR.
The RFC is executing without any problem when I execute this from the transaction SE37.
I have created communication channel in Integration Directory in appropriate manner.
I also created RFC destination in the XI system (TCODE SM59) and the same is using in the "Receiver Determiiation - Service".
I have not done any configuration at SAP R/3 side. Is any config required at R/3 end for this scenario - please let me know.
Please throw some light on this. I will greatly appreciate your help.

Friends,
Please suggest on this vague problem that I am facing. Your help would be greatly appreciated.
1. I am using SAP-PS (Projects & Systems) BAPI 'BAPI_BUS2002_ACT_CREATE_MULTI' to create the activities for a project. According to this BAPI documentation,
- First call 'BAPI_PS_INITIALIZATION' before make this BAPI call
- After BAPI call, we should use 'BAPI_PS_PRECOMMIT' and 'BAPI_TRANSACTION_COMMIT'.
2. Hence, I have developed Z-Func Module with Initialize, BAPI call - then Pre Commit and Commit.
3. This is executing from SE37 without any issues. Other parameters to make a remote call is also set properly.
4. To make sure that, I made a JCO call from Java Program using PDK for Java. This is also working fine.
5. But when I used this in the XI scenario (File-XI-RFC) this is showing ABAP dump and this is invoking from Pre-Commit module.
I couldn't figure it out why it's happening like this.
I did lot of troubleshooting and the details are as follows for your reference.
1. The mapping program is working fine without any issues. I confirmed this by writing these input values to the file (ofcourse lot of pain) inside the function module. All the values have been parsed by XI and coming to Func Module as expected.
2. No issues with logical destinations (SM59).
3. I have tried other options such as clearing the Cache...etc.
Hence, please throw up some light. If any body tried with these kind of BAPI (needs initialize, pre-commit and commit) I really appreciate your effort.
Can we enable the debugging of func module when the XI makes a call...? - I tried with Standard options that seems doesn't work.

Hi Gobinath,
      Check your SLD configuration. Looks like there is some problem with the parameters specified for your logical system..

Hi,
It seems that the SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.
First try pinging <IP address>. If there is no reply, then Boot SAP Gateway host required.
Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway
The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc.
Hope this helps.

Com.sap.mw.jco.JCO$Exception: (127) JCO_ERROR_FIELD_NOT_FOUND:

Hi All,
I am getting this error while communicating with the back-end BAPI. It says that Field IT_RETURN not a member of TABLES
com.sap.mw.jco.JCO$Exception: (127) JCO_ERROR_FIELD_NOT_FOUND: Field IT_RETURN not a member of TABLES.
Please note that I understand that this erro might come when we do not have required return structure in the BAPI. However I have debugged both the backend R/3 and frontend J2EE code and I am sure from backend BAPI is returning this structure.
To add to my surprise, I am not facing this issue every time. Sometimes this works perfectly fine without giving any error. I am suspecting this to be a communication issue between two layers.
Please suggest your inputs how should I move further to fix this issue.

Hi,
Open your RFC in ABAP editor.
Check the import parameters.
Compare them to what you are passing from your JCO call.
You will find the mismatch.
For further reference refer the document [How to Handle Import and Export Parameters of ABAP Function Module (RFC Enabled) In Java|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/608391c6-dc79-2c10-2c8c-c72861822b12?QuickLink=index&overridelayout=true]

JCO Exception 106, 102 and 104 (Very Urgent)

Hi Expert,
My scenario is File to RFC i am getting the following error.
Initially i got this error
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: resource error: could not get a client from JCO.Pool: com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool RfcClient[CC_BSV_XXXX_CTR_DIST]29fe2a7e92383d2b97a0e235d1501a19 is exhausted.

Thanks In advance,

Venki,
I guess you are not an XI person.
You can contact any XI/PI person in your organization and tell them to do mention changes in Integraion Buider: Configuration. And then check.

Hi Swapna,
Please check the logon group properties for SAP system in t-code SMLG. If there is any issue with logon group then it might cause for this issue.

PI 7.31 (single stack) posting to RFC configuration gives this error: om.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: String index out of range: 0 (raised by system extern ...

Getting cryptic error while trying to post to a custom RFC from PI 7.31 single stack.
com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: String index out of range: 0 (raised by system <extern>|pidevhost)
Does anyone recognize this error and/or know of detailed instructions for registering custom RFCs in PI 7.31. I could possibly have configured the target wrong but no error says so.
This is a File-->PI-->RFC scenario. The file processing is super simple and a configuration I have used successfully before. I would assume I'd get a different error if it couldn't parse the file.
Jody

Not shure if you already did but try getting some details with XPI Inspector. Also increasing log level for this category might help. You also may wanna check authorization (even if this should show with a different error text) in ECC using ST01.
My guts feeling is that there is something wrong with payload / signature of RFC.
Cheers
Jens
