Trusted RFC and Remote logon not possible due to Nat'd IP addresses

Hi,
We are trying to connect our SolMan 4 to our cusotmers ECC 6 and BI7 systems, the systems are off site and the IP addresses for the customers systems are nat'd when they come in and go out from our Network.
The problem we get is that we cannot set up Trusted systems or Remote Logon to these systems due to issues with the Nating of the IP adresses. We can set up all standard RFC's after adding the the appropriate addresses into the hosts file and they work fine. But the trusted RFC does not set up properly and the BACK rfc from the satelite system does not get set up properly. What appears to happen is that when you try to start a remote session SAP goes to the satelite system and finds the Instance Name and the local IP address rather than the NAT'd IP address and try's to open a session from there. I found this by going into the trusted RFC in SM59 and then going to Extra's, System Information, Target System, this then tells me the Target System information, where it shows the System ID and IP address (which is the incorrect IP address).
Anyone know how we can get the system to try to have the correct IP adress in the target system information so that we can get Remote Logon's to work??
Cheers

Hi Carl,
Based on your explanation about Nating,, how will the RFC determine to connect to Solmans internal IP after it has been directed to the IP for the Router connection.
I feel it is like configuring a jump of RFCs from one IP to another in a single chain.
Can this be done ?? I mean we have to specify an IP in the RFC connection right.. so how will the automatic jumping of IPs be done.
Sorry not answering the question but its very interesting and wanted to know.
Also went trough note # 148832, might help.
Regards,
Kaustubh.

Server0 getting down and logon not possible ( error in license check)

Hi Guys,
I rebooted my SAP server and after that server0 is in disabled mode, well both the boxes seems to be green but the server0 node in disable mode as if it is maintained by some parameter and I have changed it, which is not the case, also there is no log with dev_server0 since then. I have followed 723909 note and also copied the parameters of a running server but didn't get success. Also when I am trying to login through SAPGUI its giving me error " Logon not possible( error in license check)" while the license is already installed.
dev_w0 log says

Purchase requisition from sales document' not possible due to a credit bloc

hi experts,
i have to confirm delivery date and quantity for some purchase order items but i'm not able because i receive following message:
Subsequent function 'Purchase requisition from sales document' not possible due to a credit block'
Purchase requisition belongs to a sales order which has customer 10000.
The customer 10000 was block from FD32 but now i have unblock the customer from FD32, i have assigned customer to a category risk which is only a warning. (in OVA8 risk category 002 static check, reaction C, status/block uncheck )
There is any possiblilities to confirm quantity ?? I mean ... i understand that sales order was created when the customer was block due to credit limit exceded ... but now the customer is not blocked.
What should i do?
Thank you.

Hi Dan
If you want to confirm the delivery date then change the static check reaction to B . in OVA8 . But if you change the static check reaction to A , you can do Delivery and billing also

[SOLVED]wlan0 up - Operation not possible due to RF-kill

Hello everyone.
I've encountered trouble trying to activate my wlan0 interface and I was wishing that someone here might be able to help me.
$ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether
My attempt at trying to activate wlan0 renders the following;
$sudo ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill
Unblocking everything with RF-Kill does not seem to change much in particular:
$rfkill list all

Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes
$sudo rfkill unblock all
$rfkill list all
0: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
Enabling/Disabling the wifi-button on my keyboard only changes the Hard Blocked-parameter of hp-wifi. The Soft block remains unchanged regardless of me trying to unblock all with rfkill.

It is worth mentioning that this problem has remained persistent throughout multiple linux distributions that I've tried on my laptop. The Wifi works fine in Windows 7 but as soon as I switch to any linux distro it stops working.
I intend to put your advice to good use so any help would be very appreciated.

As I can see you have two wireless interaces, when i see only phy0 with rfkill, it's maybe your hp-wifi that force to disable phy0 interace. I think if you blacklist the driver it might allow phy0 to be enabled.
Please download and install lshw available in the community repo and enter in a terminal :
$ lshw -c network

Logon not possible (error in license key)

dear sir
I had a temporary license which got expired yesterday. but i received the permanent license today
and i wanted to install it on the solution manager server, but when i 'am trying to log in ,it throws
an error at the bottom that " logon not possible (error in license key ) "
pl given a solution
thanks

Logon using SAP* in client 000.
Probably you need to maintain profile parameter login/no_automatic_user_sapstar = 0 and restart the system before you are able to logon with user SAP*

Error - Logon not possible; none of the active logon procedures is possible

Dear Gurus,
I'm trying to configure SSL with User mapping to SICF service: NWBC.
-SSL configured with STRUST transaction and I see that it is working via Internet Explorer
-SICF service NWBC was set to: "Required with Client Certificate (SSL)"
-User mapping was set like described in this article: https://help.sap.com/saphelp_nwmobile71/helpdata/en/17/1514e9b7eb4f74b0b49327b8f2a662/frameset.htm
But I get error:
Logon not possible; none of the active logon procedures is possible
Any idea ?
Please advise,
Dimitry Haritonov

Hi,
I would try to check logs first. In transaction SMICM you can set up level of logging for ICF services. So set it up to the highest possible level (this one actually dumps whole content of HTTP request, so maybe that's not necessary) and try logon again. You should get a reasonable info and you can try to figure out why it fails.
Cheers

Mapping for ND_FORM to ND_FORM not possible due to recursion

Hi Experts,
I am trying to define external context mapping...with the steps..say there are two components ZOMP1(in which i am using other component) and ZCOMP2(this is used in zcomp1)
1. IN the component zcomp2 I define ZCOMP1 under the used components
2.in the component controller of ZCOMP2 under properties tab I create controller usage of zcomp1 and two entries are created
3.I go to the context tab of component controller of zcomp2 and drag and drop the ND_FORM node from ZCOMP1 to context node of ZCOMP2
when I do a check I get the error
Mapping for ND_FORM to ND_FORM not possible due to recursion
Don't understand why am I getting this error though the node I am trying to map is not recursive?
This is what I see in long text of error:
Message no. SWDP_WB_TOOL263
Diagnosis
Mapping from ND_FORM to ND_FORM is not permitted, as ND_FORM has its own mapping that refers directly or indirectly to ND_FORM.
System Response
The mapping can neither be created nor used.
Procedure
If you receive this error message when you check a context or when you update the mapping to context node ND_FORM, delete the mapping to ND_FORM using the context menu function with the same name.
Please help,
Anubhav

Hi Anubhav,
following restrictions apply on recursion nodes:
1. You cannot nominate a recursive node to act as the data source in a context mapping relationship. Recursive node structures are restricted to the scope of a single controller.
2. The root node of a context cannot be used for a recursion.
Please check this...

Hi Sreeni,
i did check in all the below Tcode as you adviced.
1. Clear all record at SM13, LBWQ / SMQ1, Setup tables, RSA7 for particular datsasource or application..
2. For LBWQ provide date range and delete not required records.
I did not get the 3rd point " Need to clear in CLINTS of R/3 system" of your reply.
what does that mean?
I checked all the above tcodes and got the same message as no queue or data exists".
I went SBIW tcode and activated my data source and try to change the Update mode but still it is throwing error message as "Change of update is not possible due to open V3"
Please help me out.
It will be very helpful for me if you could share steps or docs regarding this issue.

Subsequent function '' not possible due to a credit block

Hello Experts,
We have the dynamic credit check at delivery, so while creating the deliery a pop-up message comes with the exceeding credit limit and allows us to save the delivery. After releasing the delivery with VKM5 when we try to enter the picking quantity in Picked Qty column we are getting the error Subsequent function " not possible due to a credit bock. Even though the delivery is released why it is again doing the credit check. How to over come this issue.
Thanks,
Sreehari.

Hi Ravi,
While creating the delivery if we enter both the delivery and picking quantity then it is throwing the error message, now it is being released with VKM5 transaction. In this case there is no second time credit check is happeing while doing PGI.
In case while creating the delivey if we enter only the delivery quantity (not entering pick qty) and save the delivery then also it is shows the delivery is blocking due to credit check. But after releasing it with VKM5, when we enter the pick quantity in the delivery (to do PGI) it again throwing the error message of credit block. The credit check is happening again in picking.
Please let me know how to resolve the issue.
Thanks,
Sreehari.

Good issue from delivery not possible due to credit block

Hi gurus,
Please help me on this issue.while doing PGI for the delivery i am getting the following error message."Good issue from delivery not possible due to credit block "The simple credit check is assigned for the sales document type.iam doing free of charge delivery.
What are all the possible ways to get such error
Regards
Vis

but system behavior is not set in transaction OVA8, means combination of risk categories and 03 is not set.
I think you are checking the wrong risk category, please check once again the Risk category of the payer in FD32, what is it assigned and also check OVA8 with this risk category.
If you find the above settings are correct as per your observation, try to create a fresh cycle so that you will get the correct results as per your settings in delivery.
In your case what you are saying is correct, may be the risk category is changed recently this you can check the change log of the payer customer in FD32( if any change takes place).
If possible try to past the screen shot of both.
thanks,
srinu.
