HTTP Connection to ABAP System - Query String Not Allowed message

Hi All,
We are trying to create HTTP Connection to ABAP System on a SAP ECC system.
Following entries are added
1 Connection Type: H
2 Target Host: Host name
3 Service Number: HTTP Port name
4 Path Prefix: /sap/XI/engine/?type=entry
It is not allowing me to enter Path prefix as "/sap/XI/engine/?type=entry". It is throwing a warning message as "Query String Not Allowed message".
As per the documentation it is mentioned that - If the system displays the Query String Not Allowed message, you can ignore it.
It is not allowing me to save the entries succesfully . I need to remove the path refix entry then only i am able to save other wise it is not allowing me to proceed at all.
Please let me know what entry i can put for the same or let me know how can i ignore and proceed by saving the path prefix as "/sap/XI/engine/?type=entry".
Please provide your valuable help on this.
Regards,
Nanda

Load balance for HTTP Connection to ABAP System (Type H) RFC connection

Experts,
For proxy we are using HTTP Connection to ABAP System (Connection type H) RFC connection in PI to get connected to ECC. I only see the option to use Target host in the Target system settings than Load balance option. In general ABAP Connection (Connection type 3) has Load balancing status option in Target system settings.
My requirement is I should use a logon group with the message server when PI connects to ECC. How can we achieve this? At the moment I can only use the Central Instance or any dialog server (App server) in RFC but not a logon group.
Thanks in advance.
Mahesh

Hello Michal,
Thanks for your response.
Part of this problem has been solved right now...the http port on the R/3 server is 8002 and not 8000!!
Changing the port solved my problem from XI to R/3.
But the R/3 to XI error persists with the same behaviour. I have checked with BASIS, no firewall exists in between.
I have used the ip add while creating the http conn....do I have to change this elsewhere?

SM59 Error in HTTP connections to ABAP Sytems

Hi All,
My scenario is to connect to XI systems... I need to create a RFC destination (HTTP connections to ABAP Systems) in SM 59 with below details.....
Target host: xyz.abc.com
Service No. : 0000
Prefix path : /sap/xi/engine?type=entry
But SAP GUI is not accepting the character "?" ...
Can any one tell what can be done to avoid this error?

HTTP connection to ABAP runtime failed

I am building a scenario where XI picks up a file from a directory and pushes an IDoc to ECC. I have configured the interface with the Design tool, and I believe my setup in the Configuration tool are correct too, however I am encountering an error when testing the scenario by means of --
Tools --> Test Configuration.
The testing tool is giving me the following error upon processing the reciever determination:
HTTP connection to ABAP Runtime failed.
Error: 403 Forbidden
URL: http://serveraddress:port/sap/xi/simulation?sap-client=100
User: PIDIRUSER
First of all, I am not sure who the PIDIRUSER is, I assume it's a system user? Second, given that this error is a HTTP connection error, I am lead to believe that the issue lies somewhere in the RFC connection from XI -> ECC. I am not sure why exactly it's attempting to connect via HTTP as my communication channel is using the IDoc adapter with an RFC destination to connect to ECC. Possibly I have configured this incorrectly. I have read about having to configure a RFC adapter when posting messages from R/3 to XI, does the same apply when posting an IDoc from XI to ECC? Does anyone have any other thoughts as to why this error may be occuring? Thanks in advance for your time and help.

Hi
Try this
note 517484
1) Activated all services
2) In Integration builder, receiver communication channel make sure you have entered proper
host service number
path = /sap/xi/enigne?type = receiver.
3)Go to SU01 > type PIISUSER and reset the user's pw
Check out this might be helpful
http://help.sap.com/saphelp_nw04/helpdata/en/89/05793c05f0807be10000000a11405a/content.htm
1.Did you maintain Client, userid, password, and lang information in SICF transaction -> sap/xi/engine? Double click on service and check whether you have entered correct information.
2.Then you might check the roles of the XIISUSER in SU01. In some case there are some double roles, i.e., two times the role SAP_XI_IS_SERV_USER assigned. One might have the date of the last update, the other one might have apparently the older version. Delete the older roles manually and the error should disappear.
3.to send messages to xi you need a service id / pwd which is specific to your landscape usually its xiappluser. Contact your basis group for password.
4.
- Activated all services on the r3 system.
- Create HTTP connection to XI from r3
sm59-> http connetons to r3
- let us say you have created a HTTP connection in the integrationserver_XI, make sure in its settings the prefix path is set to /sap/xi/engine?type=entry. Also check its log on credentials, you can use xiappluser.
- IN Integration builder, receiver communication channel make sure you have entered proper
host service number
path = /sap/xi/enigne?type = receiver.
5. can you also try the following;
Visual Admin -> start the service,
"com.sap.aii.af.ms.app".
I don't know this Forum no fhats why i copied.
Thanks

HTTP connection to ABAP Error

What is this error"HTTP connection to ABAP Runtime failed. Error: 403 Forbidden URL: http://dst01pi:8001/sap/xi/simulation?sap-client=100 User: PIDIRUSER" ?

Make sure user PIDIRUSER has role SAP_XI_ID_SERV_USER.

Farm Remote App 2012 R : Your system administrator does not allow the use of default credentials to log on to Work Resources

Hi
Here is the situation:
I have a Farm with 3 servers W2012R2 in a Domain
Server1                           Server 2
Server3
RDSession Host            RDSession Host
RDSession Host
Connection Broker        Connection Broker (Passive)
RD Web Access
2 DNS Alias : - poc.mydomain.local (Use for the RD Web Access and points to Server1
                  -poccb.mydomain.local (Use for the Connection Broker and points to Server1)
I have setup the Connection broker in HA with Server2 as Passive Server : DNS Round Robin poccb.mydomain.local (Server1)
The certificate Manager has generated 2 CA certificates :
- 1 for the RD Web Acc (poc.mydomain.local
-1 for Connection Broker SSO and for publishing
I have created 1 Group Policy for these 3 servers and 1 GP for my client Windows 7 SP1.
Server GPO :
Computer/Administrative Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Security
Always prompt for password upon connection=Disabled
Require use of specific security layer for remote (RDP) connections : SSL (TLS 1.0)
Set client connection encryption level : High Level
Client GPO
Computer/Administrative Templates/System/Credentials Delegation = Allow delegating default credentials (Concatenate OS defaults with input above)
TERMSRV/POCCB.mydomain.local
I use no Gateway and in my collection,I have activated SSL (Like in my Server GPO)
I have now problem with SSO.
Connection with remote desktop client with server name = poccb.mydomain.local
Your system administrator does not allow you the use of default credentials to log on to the remote computer poccb.mydomain.local because its identity is not fully verified
If in my client GPO I add the physical name of the 3 servers, it works :
TERMSRV/Server1
TERMSRV/Server2
TERMSRV/Server3
Open RDP Files with server name = poccb.mydomain.local
if my connection broker connects me on Server1 , no problem
But If I arrive on Server2 & Server 3=
Your system administrator does not allow the use of default credentials to log on to Work Resources
I have searched on internet. No result for " to log on to Work Resources"
Any idea ? Thanks for your help

Hi,
Thank you for posting in Windows Server Forum.
Firstly check that, your user is using domain\username to enter the credential in the dialog box.
Now for a try, you can edit .rdp file with notepad and just place “enablecredsspsupport:i:0” line in it, save it an launch to check whether you are facing same issue.
As you are using windows 7 then upgrade to RDP 8.1. Also as you have already enter the FQDN name of server under “Allow delegating default credentials”. For a try please enable and configure for all the remaining settings as follow and check the result.
Start / Run / gpedit.msc / Computer Configuration / Administrative Templates / System / Credentials Delegation, and make sure you have the following four options enabled and configured:
Allow Delegating Default Credentials with NTLM-only Server Authentication
Allow Delegating Default Credentials
Allow Delegating Saved Credentials
Allow Delegating Saved Credentials with NTLM-only Server Authentication
Finally, open a command prompt and use “gpupdate /force” command to apply the policy directly.
More information:
Remote desktop credentials did not work
Hope it helps!
Thanks.
