Issue - A system erroe has occurred in lock management

Dear Friends ,
I have the below issue in my workflow .
When i am executing the workitem from the SAP Inbox (SBWP) it is showing the below message in the status bar .
" A system erroe has occurred in lock management " . & not allowing me to open the workitem .
I searched in forum , but could not able to track the exact cause of the problem .
Any suggestion to resolve the issue will be highly appreciated .
Regards
Prabhu

Thanks for the reply .
Usually when ever a object gets locked by some other user id it shows the message like
" Object locked by user id " . Yah i have checked SM12 , there is no entries for that user .
I think this issue is due to some other reason . Any idea please suggest .

This issue happened just 1 day back and still continues somtimes .

No WF-BATCH is not locked . This issue does not happen every time , it happens some times .other wise workflow runs fine .
I will tell you when i checked abot the error message by clicking F1 help i got the below message details-
An error occurred in lock management when attempting to set a lock on table SWWWIHEAD.
The data cannot be processed at the moment. The data is displayed.
So i think there is some issue happens in updating the entry in the table which happens some times , and gets rectified automatically . But the workflow which gets affected by this error does not start .
so any idea on the same .

BAPI_GOODSMVT_CREATE ERROR: A System Error Has Occurred While Locking

Hi All,
I am having a problem with a Z program that I am writing.
Basically, it uses the BAPI mentioned in the title. The program will read excel file that is being uploaded, and then will segregate the line items by 200 lines.
That means, if I were to upload 1000 line items, the BAPI will be called and executed 5 times (1000/200 = 5).
However, when trying to upload 10000 line items, I received this error after around 3000 line items.
"A system error has occurred while locking".
This happens when IMPORT parameter TEST_RUN is set to 'X'.
I found this after some googling: http://sap.ittoolbox.com/groups/technical-functional/sap-basis/lock-entry-system-error-1674434
I am hoping for your expert thoughts on this.
Thank you.

A system error has occured while locking

Message no. M3021 : A system error has occured while locking
I get this message in TCODE MM42 (IS RETAIL) after mass updating articles using TCODE MM46.
The lock table size was increased from 4 MB to 10 MB and still the issue occurs. It looks the lock table can store only 3600 entries, is there a way to increase number of entries.
Thanks
Jagadhish Natarajan

First, is this mass update going to happen on reguarly?
If no - you may want to further increase enque/table_size until it can finish this one-time run of the mass update.
If yes - you may want to work with your SAP basis guy and read note 13907. From your side, you may need to reduce the volume of this mass update. From the basis side, they need to determine a proper size for the enqueue table size.

A system error has occurred while locking

Hi, we encountered the error "A system error has occurred while locking" when executed transaction mm01. They said it's because the same material was launched in VL02n (outbound delivery) How can I check if it was really because of VL02n? they said that the lock was already deleted by Basis. Is there any tcode I can check where it really came from? thanks so much!

Hi,
If you are authorised for TCode - SE37 then execute the Function Module "TRANSACTION_CALL_VIA_RFC" and then enter TCode SM12 and execute. And then follow the option as suggested in earlier post.

Encountered : A system error has occurred while locking, pls help

Dear All..
pls help..
while executing some of our remote function module we encountered some locking error.. the message returned by SAP is :
A system error has occurred while locking
from message class : M3 #021
the remote function module is running bapi_goodsmvt_create in background..
the question is.. why this error occured and how to solve it ? and what is the root cause.. ?
because the error is only happened once (until now) we cannot simulate to get the error again.. so it is hard to find out the root cause..
thanks for the help..

Hi,
I am also having the same problem. I am running the BAPI_MATPHYSINV_CHANGECOUNT' to count the Articles.
When I print the error on screen, some the data shown as counted. Some are not changed and some with the following error.
System error while locking the data
Furthermore I went to the BASIS and saw that when we run this particular program its showing the locks on MARC and several tables with the same System ID from which we run the program
Can anyone come up ? Its getting too hard to resolve.

HT201413 i have an iphone 3gs and everytime i try to restore it on itunes it just keeps saying an unknown erroe has occured (29) can anyone help me with this

i have an iphone 3gs and everytime i try to restore it on itunes it just keeps saying an unknown erroe has occured (29) can anyone help me with this??

Hello Laura,
Thank you for posting in the Apple Support Communities. I found an article that has information about Error 29:
Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. Follow Troubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

System Error occured during lock management in activating BI Content.

In trying to activate BI content, 'InfoObject Actual for Netweaver Demo', on clicking install after selecting the grouping settings, i get the error message
"System error occurred during lock management"
What causes this problem and how do i successfully install BI content?. Please assist.

Hi,
The error indicates missing or inactive message/enqueue server or network problems.
Please follow the steps below to help troubleshoot the problem
1. Logon to each server separately and goto SM12->Extras->Diagnostics to test the connections for the enqueue server. This will test the access of each server.
2 Use SMGW and SM59 to test the RFC connections. See SAP Note 47682.
You may want to have your network administrator/Basis people test the connections & analyse the network.
Use the message server/logon group testing tool "lgtst" (Note 64015), & the "niping" program (Note 500235) to diagnose the network.
Have a look at attached note 124562 in order to check if you have a hostname resolution problem.
Check your DNS / network setting that this kind of problems can not lead to blocking situations of the dispatcher.
To avoid the blocking of the dispatcher you can set the parameter
rdisp/reverse_name_lookup = 0 to avoid such situations.
Best of luck.
Rgds,
Colum

When taking a test for a job application the new tab opens up and tells me a system error has occurred

I have to take a talent assessment test for a job application but when the tab comes up it tells me I have a system error has occurred. What does that mean?

Hi Bob,
I have question that I hope you can answer. I am trying to decide how to set up my wireless network with a 4th generation Airport Time Capsule (802.11n) with a 5th generation Airport Extreme (802.11n). I have read that you can extend your wireless network, but I am unsure which device I should have connected to the modem, etc., or what setup is the best way to utilize these devices. I want to setup my wireless network and get the most out of each device while making it so that internet connection is "excellent" throughout the house. In addition, I also want to be able to use Time Capsule or Airport Etreme to back up with Time Machine. Basically, I don't understand what it is that I have and how to use it in the best way.
Any help with this matter would be greatly appreciated.
Thank you,
Michael

System error occur during lock managment?

Hi all !
When I open the adminstrator workbench I am gettting the error " System lock occured during lock managment.
I can open other sessions such as RSPC, RRMX etc.
Can anyone help in this regard?
Regards
Durai

Hi,
I can suggest how to access administratoe workbench without using T.code:RSA1.
Go to T.code RSD1 then in Menu >Environment>Object Browser via AWB.
Try this for time being to access RSA1 and inform to BASIS guy he will solve the problem.
Assign points if helpful

An error occurred in lock management when attempting to set a lock on table

Hi All,
I am getting the error 'An error occurred in lock management when attempting to set a lock on table SWWWIHEAD.'
Sometimes the workitem is not created by the Workflow due to above error & this happens rarely but keeps coming.
cany anyone guide or help me how to correct this problem.Is it happening due to my custom code making locks on the above table?
Thanks in advance.
Pls do reply

I think you should not use any code to lock the table SWWWIHEAD. Please let us know why you are writing code to put lock on this table.
Thanks

DMP 5.1 = 5.2 Upgrade Issue? "An error has occurred..."

I upgraded from 5.1 to 5.2, and the VP and DMP upgrades went fine (other than the one 4305 I managed to "brick" in the process). But
on the DMM upgrade, not so much. All seemed to work well, except when trying to access the DMM admin post-install I get the following error message: ("An error has occurred. Click on the button below to try again. If this does not work, please contact your system administrator.)
I suspected a DNS misconfiguration issue on the initial upgrade, but after verifying forward and reverse DNS FQDN's everywhere, I did a clean 5.1 build and upgrade to 5.2, and still the same issue.
Everything else seems to work fine. AAI is accessible and it sync's with SaS, and there are not other visible errors reporting anywhere else along the way, but I can't seem to get past this (Tomcat?) error.
Ideas?
Thanks...
Mike

This is a known issue that is being addressed.
Description
Certificate disappears after upgrade from 5.1 to 5.2
Solution
Regenerate Certificate by changing Hostname (can be the same hostname, just select “OK” w/o changing the name).
SnS First, then DMM
Reboot Server
This is from the AAI interface...
Let me know if this works..

System error 258 has occured

Hi,
I had a working XE on XP until now, but today I got a system error during startup:
"The OracleMTSRecoveryService service could not be started.
A system error has occured.
System error 258 has occured.
A wait operation timed out."
It is possible to connect through sql*plus, but the HTML DB doesn't work. I don't see any problem in alert_log. The OracleMTSRecoveryService can be started manually, but HTML DB is still out of order. What could cause this error?
Thanks,
Lajos

After a new XP startup the error has dissapeared. I could reproduce the problem after OS restart, but shutdown and new startup helped me. I have not changed anything, I don't know what was the reason.

Transpot error" system error in lock managment"

Hi ,
When Iu2019m transporting infoobjects from BI DEV to BI Q while importing its showing u201Csystem error in lock managementu201D.
When I drill down the error its showing the following message.
Message no. AD025
Diagnosis
A system error has occurred in the lock management function.
The system was unable to determine whether a lock entry existed for the selected object.
System Response
The selected object could not be locked.
Only display mode can be used.
Procedure
Make a note of the error code and inform your system administrator
And In the error its not showing specific infoobjects ,when I searched forums I got one note 928044, but I skeptic that it works .
Please provide some inputs ASAP.
Thanks
chaitu

You didn't mention whether you are seeing this error message while building the transport/request or at the time of applying on BIQ....
Anyways, if you are seeing this message while trying to create a new transport for your infoobjects:
Please make sure all your infoobjects are not in any other *open" requests already? That is, if you have any other requests that are still open, try "releasing" them before trying to create the new transport/request.
Hope this helps.

Adobe Acrobat, An internal Error has Occured

As per usual with this product, when ever you need it most an extremely annoying issue happens!
All I am trying to do is open a damn .pdf and every time I attempt this, I get the same ol' issue "An Internal Error has Occured"
Seriously, I thought this may have been sorted out by the plethora of people working at Adobe by now.... But No!Even if I try to open Acrobat Pro, it does the same shite!
Ok,
So after an Adobe uninstall, Adobe system clean followed by re-install I can now get Acrobat to run but ONLY when given administrative control. I still am unable to get .pdf's to open on their own with out the 'internal error has occured' pop up! However, I am able to open Acrobat then drop the pdf into it, which then opens it!!! Kind of *******' annoying really!!!

Not sure if you've found a solution, I have not.
Not sure what else I can do aside from reformatting the drive and reinstalling the OS an load software from scratch. I've restored the system to last October, removed and reinstalled Acrobat Pro X to no avail. This problem is only affecting my install of Acrobat X Pro as all PDF files open without error in FoxIt Reader.
I'm not a systems guy, so I wouldn't have a clue about what to look at in the registry. Any suggestions?
Thanks!
