Abap/SIGCHILD_default profile parameter

Hi All,
I tried to add the parameter abap/SIGCHILD_default in instance profile and it's value as 'on' but I recieve a message - 'Unknown parameter abap/SIGCHILD_default, a check cannot be performed', 'Parameter value not permitted'.
I already referred the Note 790017 - sy-subrc of CLOSE DATASET if FILTER addition used and our SAP release is 701 EhP4.
However, still I continued and now parameter is added into the profile and profile is activated after SAP restart.
Any idea why it says that parameter not permitted? And I think still this parameter has no relavance in our system because we recieved that particular message ?
Thanks and Regards

Hi Juan,
Thanks for quick reply.
I found another note similar to what you said, for e.g. Note 903245 - VMC Profile Parameters are not known in RZ10/RZ11, however parameters are different.
This note suggests, 'You can add VMC parameters with RZ10, also if RZ10 doesn't know the parameter name. Important is, that the kernel knows it. If the kernel doesn't know the parameter too, it will be ignored.'
Please confirm, is it the similar case here with 'abap/SIGCHILD_default' ? In earlier note I pasted it was written - 'In the SAP Kernel 7.00, the profile parameter abap/SIGCHILD_default is available since Patch Level 0'. So I think for our SAP Release 701 this parameter is already available for our kernel and it will work fine despite that 'unknown parameter' message in RZ10 ?
In RZ11, I see the same messgae - 'The parameter name is not known'.
Thanks & Regards

Profile Parameter to execute Abap Program at user logon.

Hi Experts
I've written a small printer selection program to change the users profile parameter.
Is there another profile parameter that can be given to execute this program automatically
when the user logs on.....The reason why I'm looking for a profile parameter to do this is, that only
certain users need to have this happen at logon.
Kind Regards
Vic

Hi Javi,
I don't think you need a custom process chain for this. You can use delivered Process Chain for logic and hard-code your script name in the package. In that script you can call BADI that has your ABAP program inside.
You can find guides how to build BADI here:[How to Pass Parameters to Custom Logic BADI using START_BADI|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20f4252d-98ca-2b10-e689-f85085ae2d12] or here [Creating Custom Script Logic Keyword BADI's - BPC NW|Creating Custom Script Logic Keyword BADI's - BPC NW;.
Method IF_UJ_CUSTOM_LOGIC~EXECUTE has IT_CV as one of parameters. In your script you probably have to use *XDIM_MEMBERSET to get parameters from DM prompt. IT_CV will have all XDIM members.
Please let me know if you have any other questions.

Setting profile parameter icm/HTTP/error_templ_path

Hi, I have a SAP Enterprsie Portal installation with only java stack (no abap stack),
i want to set a profile parameter icm/HTTP/error_templ_path,
please direct me how to set this parameter,
also, i need this parameter to be applicable for the SAP web dispatcher, i mean it should be effective for all java instances (i have 2 java instances),
please help,.......................as there is no ABAP stack, i dont know where to set this parameter

That parameter you mentioned describes of where the error templates can be found
You can generate your own static or dynamic error pages for the ICM
which are sent to the client if an error occurs. Use this parameter
to specify the directory in which the ICM can find the pages.
If this parameter is not set, the ICM returns its own static error
page.
For information about how to generate the error pages, see the
documentation in the SAP Library or using the Help Portal.
SAP Web Application Server -> Client/Server Technology ->
Architecture of the SAP Web Application Server -> SAP Web
Application Server Components -> Internet Communication Manager ->
Error Handling Using the ICM.
Eventhough u have only java stack u'll have an ICM.
Since the value for the parameter is just a string mentioning the path of the folder which contains the customised web pages.
Mention the same path in all the instance profiles (in your case 2 java instances).

Profile parameter for to change password

Hello everyone.
Is there any profile parameter to change the password after certain number of days say 30 days. I see there are profile parameters for lenght , uppercase, lowecase but is there one to change the password after a given period of time.
Thanks.
Neha.

> I checked the profile parameters using the program RSPARAM. But I am not able to find a parameter to prevent the old password from being used at least ten times. I also checked in the table TPFET.
>
login/min_password_diff min. number of chars which differ between old and new password
> And also can we prevent the password being same as user id.
>
> Should these parameters be changed in the deafault profile or instance or start profile.

It depends ... you may decide this by discussing with BASIS team and as per your Company SOP. I prefer Default profile. But never use Instance profile.

Dear all,
After Ecc 6.0 installation......we want to activate one profile parameter na in RZ10, RZ11. Can anyone guide me how to activate that profile parameter, give the profile parameter name also..... Thanks in advance

Hi Harish,
To activate the profiles please do the foll:
Go to t.code RZ10 and enter the profile name you want to activate, use the pushbutton to display profiles that are available then choose the profile and activate it. Stop and restart the SAP instance for the profile through CCMS.
ABAP program RSPARAM helps you to find out the Parameters which are active for a given SAP instance.

Here's a simple perl script that should help you get what it is you're looking for - you can add all the parameters you want to search for, I just took a few of them:
#!/usr/bin/perl -w
use strict;
use sapnwrfc;
SAPNW::Rfc->load_config;
my $rfc = SAPNW::Rfc->rfc_connect;
my @parms = (   "login/min_password_lng",
          "login/password_expiration_time",
          "login/fails_to_session_end",
          "login/fails_to_user_lock" );
for my $x (0 .. $#parms) {
     my $rcc = $rfc->function_lookup("SXPG_PROFILE_PARAMETER_GET");
     my $slr = $rcc->create_function_call;
     $slr->PARAMETER_NAME($parms[$x]);
     $slr->invoke;
     print "Value for $parms[$x] is: ".$slr->PARAMETER_VALUE."\n";
$rfc->disconnect();
And running it, you'll get:
[dhull@397 scripts]$ ./read-profile.pl
Value for login/min_password_lng is: 7
Value for login/password_expiration_time is: 90
Value for login/fails_to_session_end is: 3
Value for login/fails_to_user_lock is: 6
[dhull@397 scripts]$
If you need to get your perl environment read to make RFC calls to your SAP system, check my series of blogs on how to do so here:

SSF Profile Parameter ssf_md_alg

I need to set an SSF Profile Parameter value, due to a legal requirement in Portugal regarding invoice certification.
The parameter is ssf_md_alg and i need to set it to 'SHA1', but i don´t know where to set SSF parameter values.
Can anyone help ?
Moderator message: relation to ABAP development unclear.
Edited by: Thomas Zloch on Jan 19, 2011 6:14 PM

Hello Anatoly,
I had exactly the same issue with a SSF library provided by SBKontur (RU). Their library "KonturSSF.dll" could not be loaded by ssfrfc.exe on the frontend, the trace file contained something like:
=================================================
=== SSF INITIALIZATION:
===... SSF initialization file C:\Program Files (x86)\SAP\FrontEnd\SAPgui\ssfrfc.ini found.
===...SSF library is C:\Program Files (x86)\SAP\FrontEnd\SAPgui\KonturSSF.dll .
===...SSF trace level is 5 .
===...SSF hash algorithm is SHA1 .
===...SSF symmetric encryption algorithm is DES-CBC .
===...completed.
=================================================
=================================================
=== LOAD SSF FUNCTIONS:
===...could not load SSF library C:\Program Files (x86)\SAP\FrontEnd\SAPgui\KonturSSF.dll .
After some investigation I found out by calling the ssfrfc.exe directly in a Windows command box with option -D, that the library had dependencies to Microsoft's C runtime libraries MSVCP120.DLL and MSVCR120.DLL.
Unfortunately, this is not logged into the SSF RFC Trace File dev_ssfa*, but only shown as error message in a popup window if you execute ssfrfc.exe directly as mentioned before.
So you should try this in order to find out if there are dependencies with your special library.
Kind regards

Profile Parameter : Time out for executing query on the web

Hi gurus,
I am executing queries on the web directly. This can be done from query designer with the button that says "Execute query on web". The problem is that for queries that take more than 600 Secs to run, I get an Application timed out error. Queries that take less than this run smoothly.
Can anyone please tell me the profile parameter associated with this particular setting. It is not rdisp/max_wprun_time, I know for sure since the value for this profile parameter in my system is 9999. Please help.
Thanks & rgds,
Sree

Profile parameter icm/host_name_full is not set correctly

Hi All,
I am working on Solution Manager 4.0. When I execute TCODE "SOLUTION_MANAGER", it gives the following error:
Profile parameter icm/host_name_full is not set correctly (see long text)
When I click on "Long Text", it gives me the following message widow:
Message Number: SOL_GRAPHIC002
Diagnosis
The graphic cannot be displayed, since the profile parameter icm/host_name_full is not set correctly.
Procedure
Set the profile parameter icm/host_name_full correctly.
For more information, see SAP Notes 434918 and 677118.
I have referred to both the notes above. In note# 434918, it says that I need latest kernel patch (which is 150).Also the icm/host_name_full parameter parameter was not there in Solution Manager, so I created in the following manner:
Parameter Name =icm/host_name_full
Parameter Value=smgdcs1s.example.com
But however, the error continues to be the same.
Kindly help me asap.
Thanks in advance.

User Profile Parameter ID KVS not work

Hi,
I've got some troubles with parameter id KVS. I set it in my user profile,
parameter = KVS
value = B2
description = Version (CO)
when I call report GPCQE53LSADXCC16KZ1R96N5156001, there are two fields with this parameter,
and their value remain "0" instead of "B2".
I need to put the parameter value on one of this two fields, how can I do?
Could someone help me?
thank you in advance,
Fede

You can run Incremental Sync from user profile 3-4 times. This will delete the user profile from SharePoint UPA.
Now, we need to run UPA clean job timer job available in Job Definition inside central administration.
This is a by design issue which you have raised. But, to get it done on the same day you need to follow above mentioned steps. This would be done in some hour and cannot be achieved in 4-5 minutes. So, your original request is a by design issue and can be
done i some hours.
Thank You, Pallav S. Srivastav ----- If this helped you resolve your issue, please mark it Answered.

Configuring profile parameter for a table lock object

Hi Experts-
I want to set the 'wait time' (_WAIT) parameter as a profile parameter for a table lock object.
I have created a lock object on a ZTable. I lock and unlock this object in exclusive non-cumulative mode through the enqueue and dequeue lock object function modules. These generated FMs are invoked via my custom function module.
My function module will run in the background as a scheduled task in R/3. I execute the Enqueue FM at the start of the FM and keep the table locked until the last step finishes in my FM and then I Dequeue it. I want to have the processing wait and retry the Enqueuring FM at set intervals in case the one run doesn't finish entirely and a new run of this same job kicks off.
Thank you,
- Vik.

Set the wait parameter = 'X'. These means that if it encounters a lock, then it will wait a certain time for the lock to be released. This certain time is a system value set by your basis team. I don't imagine it being a very long time.
CALL FUNCTION 'ENQUEUE_EZPIPHYINVREF'
       EXPORTING
            MODE_ZPIPHYINVREF = 'E'
            MANDT             = SY-MANDT
            _WAIT             = 'X'.

Profile parameter for passwords - conflicting documentations.

Greetings!
I've encountered an issue with profile parameter login/password_max_idle_productive
Integrated help in SU01 says:
You can use the profile parameter login/password_max_idle_productive to define the point as of which the validity of the productive password ends. The time is calculated from the date of the last password change plus the number of days specified in the profile parameter. Password-based logon is then not possible from this point.
This makes this parameter redundant (we have login/password_expiration_time ).
SAP Library says (see link below):
Specifies the maximum period for which a productive password (a password chosen by the user) remains valid if it is not used.
Which suggests that the time after which passwords are considered expired is calculated from last logon date plus whatever is the parameter value.
SU01 help specifies explicitly how this parameter works but it conflicts with a more ambiguous description found in the SAP Library. The observed system behavior on logon is in line with SU01 help, but report RSUSR200 does not list the user as having an expired productive password.
We're on ECC 6.0, release 701 with support package 3. I could not find any SAP notes relating to this issue.
Has anyone encountered this issue before or have I just run into an odd glitch?
[SAP Library|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/22/41c43ac23cef2fe10000000a114084/frameset.htm]

It sounds like you have a requirement to set the expiration time (when the user has to change the password) which is for a different user group than those for which you want to disable an idle password. Currently, both are global settings and affect both user groups (actually, all users of type DIALOG and COMMUNICATION - only SERVICE and SYSTEM type users are not affected).
In that there is an option for you... but be aware of license implications... or you can upgrade to 7.02 early next year (I think this is the correct release, time and release "alias" for it..) and then the config your security policies client dependently!
Currently, your best option is to not set these two global parameters illogically and monitor the user group manually from RSUSR200.
In the wild, many folks use the user type difference to workaround this, but that is also global to the user type so they are excepted from the expiration time as well. Additionally, not all functionality is available to them on the client side (e.g. SAP Logon Tickets won't work) and the authority-checks are even slightly different on some special cases.
Personally, I don't understand why users with authorizations to make purchase requests only should change their passwords more often (expiration time) or be more active (idle time) than those with SAP_ALL etc.
> I hadn't considered SSO since we do not currently use it.
SSO solves several of these problems by deleting the password completely...
Cheers,
Julius
