RFC model creation problem in NDS

Hi All,
I am facing a strange problem while creating a RFC model in NDS.
After providing all the logon informations to server, the editor says "Connect to SAP gaetway failed. Unknown hostname..."
Where as I can connect to SAP system through the SAP gui using the same logon details.
The Hosts file does have entry for the hostname.....Tried using a newer 7.0.10 version, but problem still persists.......
What might be the loose end here!!!!!!!!
As far I know, NDS uses tcp/ip protocol to connect to servers & the Host file entries should help it in getting connected to SAP.....
Does it use some other layer to connect??? HTTP???
Any pointers are welcome. Thanks in advance..
Regards,
Sandip

Hi Sandip,
It fetches and populates values from SAPLOgon.ini file stored on you machine.
Same file is used to show system list in SAPGUI logon pad.
So, If you are getting system on logon pad then it should show same in the dropdown.
One more point:
Is you backed system uses message server to rought to hte server? If so, then provide Host or IP of the message server instead oh Application server.

Cannot find the maps stored in import manager during port creation

Hi All,
I am unable to find any maps that i saved in import manager during port creation ,the maps are not showing in dropdown list during port creation in console.Do i need to store the maps that i have in import manager in specific place under mdm server,so that i can see them during port creation.
All i need to do is assign my import map during inbound port creation,but i cannot find any maps in console.
Could I know whether i am storing my maps some where other than default location.
Thanks
Aravind

Hi Aravind,
First of all check the remote system assigned to ur Port. After that go to import manager. When u logon to the import manager, u get a window "Connect to source". Mention the same remote system over there.Select the file type.Browse the file and map the fields,values,field matching and save the map. then unload the repo and assign the map to the port.
Second way is, u create the port first and give any particular remote system to it. Put the file (u want to use for mapping) in the ready folder of that port and in connect to source window select the type as port, remote system(ame as used port port) and port.then map and save. unload the repo and assign the map to port. Ready folder will be in ur server at location: C drive or D drive->SAP MDM 5.5 ->server->distributions->repo name->inbound->port code->ready. For this option, Ur port type should be manual. After assigning the map u can change it to automatic or keep it manual as per ur requirement.
Hope this solves ur problem.
Regards,
Dheeraj.

Why T-RFC Port canu2019t handle Partner Profile Segment Release Version.

Can TRFC Port handle the segment release of each of the segment if configured in Partner Profile.
As per sap, in Partner Profile, if we maintain the two field "Seg. Release in IDoc Type" and "Segment Application release" to a SAP Release lower than the current release version then all the segment populated by the IDoc adapter should be populated as per the lower release structure.
For test Purpose I have created two IDoc using File Port and TRFC port and for both of then I have maintained the Partner Profile Fields "Seg Release in IDoc Type" and "Segment Application Release" as 46C although the latest release is 701.
In the IDoc there is a custom segment ZE1PMX with two Version Release 46C & 701. 46C is having 7 Fields and 701 is having 9 fields.
Test using TRFC Port: Using TRFC port the IDoc that is getting generated are not having the segment structure of release 46C instead of that it is taking the segment structure of latest release 701 which is having 9 fields.
Test using File Port: Using File port the IDoc that is getting generated are having the segment structure of release 46C instead of latest release 701 which is having 7 fields which is desirable.
I have also done these testing in other SAP release like 700 and found that while saving the partner profile with a lower segment release number it throws an warning message as "Segment definitions missing for release 620/620" and IDocs are not getting generated with a error status Code 2 "Segment E1BPMEPOITEM1 is unknown in Release 620 /". But from release 701 sap allows us to save the Partner Profile without warning and also creates the IDoc without error but the segments takes the latest release structure instead of the release maintained in the Partner Profile.
If any one has already done some investigation on this issue please let me know why there is a difference in TRFC Port and File Port. Is there any other configuration that is missing for T-RFC Port.

Hi Dennis
This forum is focused on [SAP NetWeaver Gateway|http://www.sdn.sap.com/irj/sdn/gateway], i.e. the (relatively) new OData/REST-orientated mechanism to expose ERP data and functions.
You're talking about the ('classic') Gateway i.e. the service that runs on port 33<SYSNR>. As a result, you are better off posting in the forum that covers that Gateway, i.e. [Application Server Infrastructure|SAP NetWeaver Application Server;
The names do make it confusing, for sure.
Good luck!

Can't run form from Form Builder 10g - Port configuration problem?

Hi,
I have installed the Database (10.2.0.1.0) and the Developer Suite (10.1.2.0.2) on two Linux machines (Red Hat Enterprise Linux ES 4 Basic).
If I enter the frmservlet-URL manually everything seems to be fine.
In one case I enter http://127.0.0.1:8890/forms/frmservlet, in the other http://127.0.0.1:8889/forms/frmservlet; in BOTH cases I get eventually a dark square and the status bar says "Applet oracle.forms.engine.Main started".
HOWEVER, if I create a simple form with Form Builder and click on the Button with the green traffic light ("Run Form"), the form runs only on the machine where frmservlet listens on port 8890.
On the other machine (frmservlet configured to listen on port 8889) Firefox pops up, the URL "http://127.0.0.1:32979/6dOrpwghCqnp8PhMT7KVT533m3IaArqFbPqPBOztZXWYSsNy" gets called, and nothing else happens. The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and it stays like this forever.
I assume this is a port configuration problem, but I don't have a clue where to start.
Any suggestions how I should proceed are greatly appreciated.
Thank you very much in advance!

Hi Frank,
Thank you for your reply.
I doublechecked my configuration.
In the dialog Edit --> Preferences --> Runtime the Application Server URL is set to "127.0.0.1:8889/forms/frmservlet".
However, when I attempt to run the form, the URL "http://127.0.0.1:33140/W2dwbV9eXS2fPkuKlxNhCxFWdEihwDviat2uV7ycrSotqwDN" gets called.
The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and that's it.
I wonder how the port number 33140 got selected. Interestingly, this time it is a different number; last time it was port 32979. In fact, the port number seems to change each time; I tried again and now it is 33189.
I will now try to set the port number for the frmservlet to 8890.
I choose Edit --> Preferences --> Runtime and set the application server URL to "127.0.0.1:8890/forms/frmservlet".
I stop the container, open /home/oracle/OraHome_1/j2ee/DevSuite/config/default-web-site.xml and change the port number to 8890:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-site PUBLIC "Oracle Application Server 10g XML Web-site" "http://xmlns.oracle.com/ias/dtds/web-site.dtd">



<web-site port="8890" protocol="http"
display-name="Oracle Developer Suite 10g instance of Oracle Containers for J2EE Web Site">

 
 
 <default-web-app application="default" name="defaultWebApp" root="/j2ee" />

<web-app application="forms" name="formsweb" root="/forms" />


<web-app application ="reports" name="web" root="/reports" />
<web-app application = "reports" name="demo" root="/repdemo" />
 
 <access-log path="../log/default-web-access.log" />
</web-site>
I restart the container, start Form Builder, connect to the database, and open my test form.
When attempting to run the form, the URL "http://127.0.0.1:33437/Pl0n3ky9vmU5z37A7ScBnQhsGwq3jwuzJpgTAKWPMOYIzT8K" gets called (again a new port number, apparently picked radomly within a certain range) and nothing happens: "Waiting for 127.0.0.1...".
However, when I enter the URL http://127.0.0.1:8890/forms/frmservlet I do (eventually, after confirming that I trust the certificate etc.) get a darc rectangle and the status message "Applet oracle.forms.engine.Main started", which tells me that my setup can't be that far off target.

Port Mapping Problem with AEX

I have a new Airport Extreme and a problem that did not exist with the Airport. I connect a Toshiba network camera to an Airport Express, set as a WDS remote, with the netcam connected to the wired ethernet port of the Express. I can see the netcam, which also functions as a web server, on the internal 10.x.x.x address, and have reserved a discrete 10.x.x.x address via the MAC/DHCP reservation function of the Extreme. Just like the older Airport which did this without a hiccup, I should be able to map a port (e.g. 1200) on the public IP to port 80 of the internal 10.x.x.x address, then access the netcam on the internal network from any browser (http://67.x.x.x:1200). My cable modem is just that: no router involved other than the Airport Extreme. I'm using the latest Extreme and Express firmware, and am either missing something with the new Leopard firewall, overlooking something else, or dealing with a product flaw. Any help is appreciated and Happy Holidays.

I have forwarded the port (have tried several different ports actually) in what I think it the correct way: using the Airport Utility, connected to the Airport Extreme, and, under advanced options, selected port mapping, entered the public TCP port of 1200, then the private 10.x.x.x IP address of the netcam (which I can access from the internal network with no problem), coupled with the private TCP port of 80. I then attempt to access the netcam from the Internet by entering http://my cable modem IP address:1200 (or another port to which I've attempted to map). This method worked for two years with the Airport, but, with the Extreme and Leopard (simultaneous transition), I'm stumped. After reading other about other port mapping problems, I reserved an IP address for the netcam based on its MAC with no positive results. I also set the firewall through the Security icon in System Preferences to allow all incoming connections. Thanks for taking the time to respond.

RFC Port

Is it necessary to create RFC port when I am sending IDOCS to XI? If no then under what circumstances do we need to create a RFC port. Why do we need to create the distribution model through SALE transaction.

Hi Sonia,
If you are sending IDocs to XI ....
1. You need to maintain a Partner profile for XI in your R3 system using transaction we20.....
2. Now the message type of that IDoc will be listed in the Outbound table of the partner profile.
3.Now the port that entry of messsage type will be using --- should be configured in we21
4. The RFC destination that port will be using should be created using transaction sm59
You dont need to configure any ALE settings at the XI side....
**Reward points if helpful..

RFC Message: Internal Problem, in REDWOOD CPS.

We have Redwood CPS 7 connected up to SAP IS-U Supply.
We keep getting random RFC errors when executing a script.
Any Idea
ERROR LOG   *******************
ABAP_RUN: R/3 call BAPI_XBP_JOB_OPEN failed
RFC error: XM034
RFC Message: Internal problem (function BAPI_XBP_JOB_OPEN)
TCTRETURNS/        : deleted
/ERROR LOG   *******************

Hi,
if this is a random issue I assume that the authorizations of the CPS communication user are OK, otherwise please verify:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/49/bb35b8623a489aa63abd9f5ebf2448/frameset.htm
If this random issue happens only if you execute your custom script, I would assume that the script wants to create a job with invalid data. For example: some data is missing or wrong like start date/time, job class, job user, job name.
Let's analyze what you have posted here:
RFC error: XM034
RFC Message: Internal problem (function BAPI_XBP_JOB_OPEN)
-> XM034 point to the XMI log
-> use transcation RZ15 to analyze the XMI log
-> XM034 means "problem detected" (see appendix 8 of document ftp://ftp.sap.com/pub/icc/bc-xbp/BCXBPDOC70V3.pdf)
I locked into the code and indeed it seems that function BAPI_XBP_JOB_OPEN returns this message if the job cannot be created.
So if Sys- and XMI-Log cannot help you in solving this issue, I would create a message for dev. support.
Cheers,

WSDL version used for port creation in SOAMANAGER for Netweaver 7.01 SP-5.

Hi,
Does SOAMANAGER refer to a particular version of WSDL while creating the logical ports for consumer proxies. I'm asking this because after one of the upgrades in our ECC system we find that the authentication configurations of the port are automatically done based on the WSDL now, however this was not the case earlier.
Also logical ports created manually are giving runtime exception (Soap FAult Code : 1). Does logical ports creation necessarily have to be done from WSDL.
Please throw some light on the above, if any of you have faced this issue already.
Regards,
Avishek.

We got a reply from SAP that from NetWeaver 7.0 SP3, logical ports will be created based on Security policy mentioned in WSDL. We can however override this by creating the port manually and the SOAP fault code error can be resolved by manually entering the SOAP Action for each method of the Service in the 'Operation Specific' tab of the Logical Port details.

Port A000000016 is not an RFC port

Hi,
While configuring ALE/IDOC configuration I am getting below error while distributing Model View.

I have generated the partner profiles and that is showing port A000000022 is assigned with the rfc. but this Model View is picking A000000016 port again & again and throwing error. This all happened after we did the refresh from prod system.
Will appreciate early help.

Go to WE20 and select the partner system to which you are communicating. now select the

you A000000022 here for all the message types in the distribution model.* Even if one message

In addition also check if the port A000000022 has correct RFC Specified thru WE21.

Photosmart printer D110A CN732A How do I solve a port match problem?

operating system: windows 7
Error message: port match
Any changes made to your system before the issue: No
When I go to print something It tells me it's printing, but then never does. The explanation is always just the simple "error". I've used troubleshoot, re-started everything and ran the diagnostic test which told me it was a port match problem. My printer will still copy.

Hi there,
Try downloading and running the print and scan doctor located here:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03275041&cc=us&dlc=en&lc=en
It can fix a lot on its own and if not give a better idea of what is going on.
Best of Luck!

WRT54G (ver 7)-port forwarding problems (eMule)

Hi I want to use the eMule file sharing program and the problem is I cannot forward any ports (this problem already occured at other programs too) ... Im sure Ive typed in the correct port ranges, and used the correct IP-adress... I tried to use static IP adress, furthermore ive disabled the "Block Anonymous Internet Requests " option, without any success... I cannot find any firmware updates for this version either... pls help

Please open the router configuration interface at http://192.168.1.1/ (or whichever address you use to configure the forwardings). Click on Status on post the full status of your connection.
Also post the exact settings which you use for the port forwardings.
On the computer to which you forward and which is running the emule server, open a command prompt window, enter "ipconfig /all" and "netstat -aon". Post the full output of those two commands as well.
For few more things to check see this Checklist.

Doubt in RFC Port

I created RFC destination and then when I try to create RFC port for the XIServer and I don't see the RFC destination when I click the input help. Is there some equivalent of actiavtion in R3. I went back again in RFC destination and I see the destination is very much there. The name of my RFC destination is ZXISERVER2. Does that make a difference.

Hi Sonia,
To log in to the R/3 or XI system there will different types of users like dialog users,system users.
Dialog users are the one who will log in to the system via log on pad.
System users will log in to the system directly. The system user and password should be provided in the RFC destinations so that it will directly log in to the system during runtime or execution of any interface.
>>i]When I say Remote Connection it shows up as user02 in the logon screen. Why is this happening?
You might have given dialog user id because of this it is showing log on screen again. Ideally it should go through the as u click on the remote connection if u are using system user details.
Regards,
Prasanthi.
