Load balancing after ECC 6.0 upgrade
Hi
I we this configuration on ECC 6.0 upgrade:
SAPGUI 7.10
SAP_BASIS 700 Patch level 15
SAPportal ESS
Webdispatcher Installed
Internal ITS
Single sign-on
Can somebody assist as with identifying the problem with load balancing (PUBLIC) E.g. When running ESS remuneration package via the Sapportal. we have configured ITS-Based GUI Services on transaction SICF for customised ZESS_PZ11PDF service.
When we have load balancing group on the load balancing does not work, because I see somebodyu2019s payslip
but when using one app server I see my own payslip. Please help.
Hi PR,
Please take a look at the following link:-
http://help.sap.com/SAPHELP_NWPI71/helpdata/EN/28/75153a1a5b4c2de10000000a114084/frameset.htm
"You can only use the SAP message server for HTTP load distribution if
the browser is the direct client of the message server. If another
component lies between the client (browser) and the message server, (for
example, the portal), you cannot use the message server to distribute
the load."
When using the External ITS you could balance the load using the message server and logon groups. In 700 this functionality is not present if there is not a direct connection to the client (Firefox or IE). So you will have to install the webdispatcher to balance the load.
Hope this helps

Error in WBS Element Hierarchy load after ECC 6.0 Upgrade
Hi All,
After ECC 6.0 Upgrade in R/3, we are doing test load in a Test server. While doing, we have encountered an issue with 0WBS_ELEMENT Hierarchy load. The message in the monitor is like below.
"Node ID 00014240 has not been included in the hierarchy
Message no. RH207"
When I run the same hierarchy in another system which is not upgraded , it works fine.
Anybody has faced similar kind of issues and can throw some light on this issue?
Thanks,
MohanTry activating the Heirarchy in R/3 and re-trigger the load, error is very specific to structure of the hierarchy. there is a possibility that this Hierarcy could have got inconsistent after the upgrade.

PI connections to Load Balancer on ECC
Hi All,
I have a doubt regarding PI connections to ECC.
Where can we check how does PI connect to ECC.
What is url or host name and port it is using.
what is the protocol.
also if there is a load balancer used for ECC. How should PI connect to it.
ThanksHi Prabhu,
--> If you want to know whether the ECC system is connected your PI system or not.
-->If you want to import the interfaces like RFC and IDOC from your ECC into PI system we need to have connection from PI to ECC.
-->Its quite simple while creating the name space select the radibutton import of rfc and idoc from the sap systems permitted and maintain the required parameters and under imported objects try to import the RFC or IDOC if the connection is established with ECC from PI list of IDOCs and RFC's will be displayed.
-->other wise it throws connection to ECC is not established.
-->It does not matter whether we are sending the IDOC or receiving the IDOC from ECC.Because the connection is not dependent on these factors.
-->For connection with ECC port is not required.But in the case of Idoc scenario it is required.

No blank first column in Excel after ECC 6.0 upgrade
Hi,
I am facing a weird issue. There was a recent upgrade to ECC 6.0, after the upgrade the excel sheets that are downloaded from SAP transaction COOIS do NOT have a blank first column.
Is there a way to fix this issue, some external applications use this excel report to read the data and it is really difficult to fix all those applications. Please do let me know if you have any clue.Try activating the Heirarchy in R/3 and re-trigger the load, error is very specific to structure of the hierarchy. there is a possibility that this Hierarcy could have got inconsistent after the upgrade.

SAPLFAGL_ITEMS_SELECT runtime error in FAGLL03 after ECC EHP 7 upgrade
Hi all,
We have recently upgraded to SAP ECC to EHP7, after this we are getting SAPLFAGL_ITEMS_SELECT runtime error in FAGLL03 report.
Runtime error is not about a time out
I have searched for a note but could not find any on this problem.
Information on where terminated
The termination occurred in ABAP program "SAPLFAGL_ITEMS_SELECT", in
"FAGL_GET_ITEMS_BSEG". The main program
was "FAGL_ACCOUNT_ITEMS_GL ".
In the source code, the termination point is in line 412 of (Include)
program "LFAGL_ITEMS_SELECTU08".
Thanks in advance,Hi,
Check this SAP note1578577 - FAGLL03: Dump DBIF_RSQL_INVALID_RSQL. Another one is 1728986. Cannot check further as I am not aware of exact patch level.
If this does not help kindly raise it to SAP as dump is in standard object.

BSP iview not working after ECC 6.0 upgrade
Hi,
We are using MSS application in our portal.When we click the Employee list under manager profile it redirects us to a new page aontaining 3 to 4 iviews like general data,Personal data(Par file based iview) etc
After selecting the employee all data pertaining to the employee appear in these iviews(data comes from SAP HR system).There is one more iview that represents the emergency information of the employee that is a BSP iview.Few days before we have upgraded ECC 4.6 to ECC 6.0 after this upgrade we are getting values in all par file based iview but the data is missing in the BSP iview.
Can anyone help?
Regards
ImranHi,
Are you getting any error? After upgrade do you activated the bsp service through
T Code: sicf
then Service Execute, then
defalut_host --> sap -->bc --> bsp --> sap -->your BSP Application Name, then right click and Activate.

Open Dataset for input in BINARY MODE not working after ECC 6.0 upgrade
Hi All,
Our requirement is to download an XML file from the application server and there is a customized program to download these files.
This program uses the statement, Open dataset ...for input in BINARY MODE
and it works perfect for 4.7. There were no issues. But, after the upgrade to ECC 6.0 this does not work.
When the data is read in ECC 6.0 , it is shown in some special characters and it could not be opened with XML editor and the file is not completely downloaded. I read through the forum and tried the following statement as well,
Open dataset....for input in LEGACY BINARY MODE.
After this statement, there were no special characters, but there is a blank space introduced before every character.
Example : TEST(actual)
T E S T (After the legacy binary mode)
Could you please let me know if there is any solution to rectify this problem. Appreciate your help.
Thanks a million.
Edited by: Manikd on May 12, 2011 3:52 PMBut this program was already using BINARY MODE and after upgrade this is not working. I know, it may work in TEXT MODE. However, I cannot change the whole program to TEXT mode now.

Problem with ITS after ECC 6.0 upgrade
Hi All,
I am facing problems with customized ITS application created based on CATW. It does not work properly after an upgrade to ECC 6.0 from 4.7. Some of the screens user interface is different when i compared that of with 4.7. I came to know that ECC 6.0 uses the Integrated ITS where as 4.7 uses the Stand-alone ITS. What is the difference between them? Is there any way to deactivate the Integrated ITS and run the application on ECC 6.0 as it was before on 4.7?
Any help much appreciated.
Thanks,
Naga BokkisamHello Naga,
can you be more specific about the differences between 4.7 and ECC 6.0? Are you using the SAP GUI for HTML (~webgui 1)?
With best regards,

Browser Load Slow after 10.4.6 upgrade
All my browsers - Safari, Camino, Firefox - load pages really, really slow after upgrading to 10.4.6. The browsers are all the latest versions. I've read it could have something to do with the recent Java update, but haven't found a good way to resolve the issue. My internet connection is fine.
Any suggestions? Thanks. Terry.I have 4.2.2.1 and 4.2.2.2 set in at least one of my locations. I havenn't noticed that much diff' personally. Many do gain from this inclusion. It's fairly well known by now.
I guess the main point would be that it is an ISP issue as opposed to a Safari problem.
Apple Forums are under supported and sometimes won't load. When I get puzzled I use http://www.dslreports.com/forum/macdsl as a Test. It is an interesting Apple oriented site and loads "instantaneously" for me.
Good Luck, JP -
Final Issue Indicator not set in maitnenance order after ECC 6.0 upgrade
Hi,
We encounter this problem after upgrading to ECC6.0 from SAP R/3 4.6C
Final issue indicator (RESBD-KZEAR) is not being set in maintenance order (IW33) for sub-component non-stock items in General Data page
Would be great if anyone could guide in this regard
Detailed Scenario:
1) Maintenance Order is created (IW31) is created in plant A
2) For non-stock items, reservation created by maintenance order creates a purchase requisition
3) Account Assigned STO (against maintenance order) is created from purchase requisition
4) Transfer Posting done from Plant B (351 movement) for complete qty
5) GR at Plant A done (101 movement) for complete qty.
6) Final Issue Indicator is not set in General Data page eventhough the complete quantity is delivered.
Thanks

Edited by: muthukumarv on Apr 2, 2010 9:03 PMHi,
Please check in the STO if the "Delivery completed" indicator is checked or not?
If Yes, then search some correction notes of SAP and get it implemented or raise OSS message with SAP to get the Final Issue indicator to be set in maintenance order.
If No, then ask your MM consultants to investigate that. They can check the config of "Goods Receipt" Or check if the total quantity GR has been done Or some Under delivery/ Over delivery tolerance has been maintained.
Thanx.

Impact on BI after ECC 6.0 Upgrade from Ehp 3 to Ehp 4
Hi All,
We are planning for an upgrade of our ECC 6.0 System from Ehp 3 to Ehp 4.
Could you please provide me inputs in what needs to considered in terms of BI system?
I know the following thing:
1) Delta Queues must be cleared before the upgrade starts but what needs to be considered for FI and CO Data Sources.
Any SAP Documentation available?
Thanks,
NeeleshWhat version of BI is yours...3.5 or 7.0???
Unless the ehp4 is bringing some functional changes to FI or other functional datasources which needs to be replicated on to the BI side.
i think the below link might help.
Technical news brought with EHP3 and EHP4 compared to ECC6
Thanks

Load balancing not functioning
Is load balancing actually supposed to load balance? I have two servers in the failover group, with 125 DTUs on one and 0 on the second one. The documentation is a little vague on this and it says that the load balancing will only take effect if one server goes down (meaning if you have three equal servers and one drops the new connections will be distributed across the two remaining servers).
Is there a way to balance between my two Sun servers?Yes, load balancing is supposed to balance load. This is not restricted to the case of failover.
But load balancing happens only at certain times in the lifecycle of connections/sessions. It can occur when a DTU connects, when a smart card is inserted or removed, when a user logs out or when a kiosk session exits. For a new connection or token, it obviously occurs only when there is not yet a (non-"idle") session for the connecting token. Load balancing happens before the login prompt is shown, so if the client sits showing a login prompt for a long time, it will not be rebalanced when the user actually turns up and logs in. (Only with NSCM there may be load balancing after the user has entered her name.) Load balancing does not happen, if the user never logs out or if a kiosk session never exits. This includes cases where a kiosk session loops internally between user sessions instead of exiting - that is one of the reasons for the '-t timeout' option of the Sun Ray Windows Connector kiosk session type.
Sessions may accumulate on one server as you describe, if you don't use mobile sessions (smart cards or NSCM) and your users rarely log out or your kiosk session never exits. You may easily get into this situation, if one server is down or slow to come up when all the DTUs connect after a cold (re)start or other downtime.
Other reasons why loadbalancing may fail are:
- The server group isn't formed properly. The servers page in the admin GUI or the utgstatus(1M) command must show all servers in the group as trusted, online, up and available. (This must be true from either server.)
- You forgot to include the -g option to utpolicy(1M), when setting server policy on the command line.
- You manually edited the auth.props(4) file and disabled it. -
ML1000 RPR load balancing and multicast problem
Hello,
We have SDH network consisting in a STM16 ring with 7 ONS15454 MSPP nodes, sw version 9.0.1. In each node we have a ML1000-2 card connected in a RPR configuration through VC4-8C(8x155Mbs) circuits.
My questions:
Q1 We had expected the ring to balance itself but instead 90% of the traffic is going anti-clockwise which is the direction of the POS-0.
Q2 We are not able to transmit Multicast packets and we sometimes have problems with udp losses. Could this be due to a bad configuration of the ML-1000? Should we investigate higher in the core switches(6500’s)?
ThanksManuel,
I just published a document on load balancing on the ML card. (ML Load Balancing after 5.doc).
Check the document section in the Optical Forum.
Also check the on-line configuration guide.
http://www.cisco.com/en/US/docs/optical/15000r9_0/ethernet/454/guide/45490a_mlcardovw.html
As for question #2. o may find some answers on multicast in the load balancing document or configuration guide. If not, I suggest opening a TAC case so they can verify your ML configuration.
Hope this Helps,

Apache HTTP proxying for load balancing only to a group of non-clustered WL servers
Hi,
We're running WL Server 6.1 SP 2 on Solaris 2.8.
For the Apache HTTP proxy plugin, if you use the WebLogicCluster http.conf option,
do the WL servers you want to load balance across have to be part of a WebLogic
cluster (if you are prepared to do without failover, as I know it would need to be
a proper WL cluster to replicate session info for failover). Can you load balance
across a group of non-clustered WL servers, and maintain the user session to the
one WL server so that it doesn't switch between servers on alternate requests for
the same user session, or must the servers be configured as a WebLogic cluster?
Paul
We find that if you have a collection of WL servers that are not configured as a
cluster, that it will load balance alternate requests to each server, but it will
not pin a user to a single machine according to their session so for 2 servers, 2
differetn sessions get created, one on each machine.
Is this because it doesn't normally do this, but sends the user alternately to a
primary then secondary which works in a cluster because the session is replicated.
I thought the secondary was only used when the primary failed.

You don't have to use the clustering option. To get failover, you'll have to
use the JDBC persistence option of WL.

The primary/secondary stuff requires clustering. If Apache continues to
"load balance" after the first request, you need to either use JDBC session
persistence or use a different load balancer (like mod_jk for Apache or a
h/w load balancer with support for sticky).

ECC 6.0 UPGRADE - BW 3.10
We are planning to upgrade our source system from 4.6C to ECC 6.0. We are on BW 3.10 ( But planning to upgrade to BI 7.0 once after ECC 6.0 upgrade)
Would like to know,
1. Do we need apply any plug-in requirements to accommodate the ECC 6.0 compatibility?
2. Will the existing BW 3.10 work without any issue with ECC 6.0?
( We are not going to do any change with new Business content available with ECC 6.0)
3. What are the other precautions, we need to take in order to work BW 3.10 with ECC 6.0?
Advance Thanks.refer replies here:
