Hi Abhishek,
Thanks for your information.

 First Problem
I am not able to create the user from portal directly. Its showing the fallowing error.
An error occurred in the persistence; contact your system administrator.
so i had created the users in WAS by SU01.
Second
We have some users at production server ( Assume 5 users ). and those users need to be mapped at portal. So that those users can directly enter into portal and operate on SAP system .
If u dont mine Please provide with me the steps to fallow
Third
i had created some transactional Iviews that are working fine when i am log in with Administrator( super administrator role). The problem is that the reports are not showing when i am log in with general user ( with out super administrator role ) .
Its showing the error
Could not able to look up the system.
And the problem with user mapping also .
For aministrator its working fine .and for a general end user ( created on WAS )
i am not able to provide user mapping. Its showing
There are no systems available for user mapping for the selected principal
wat could be the problem ?

How to stop the users from changing the Decimal in SAP

How to stop the users from changing User Profile

Hai,
It is not possible to restrict SU3 to display, because it has only S_TCODE has the authorization object.
If you really want to restrict users from changing their profile you have to remove the SU3 access and give SU1 or SU2 which gives access only to Personnel details and Parameters.
Hope this helps.

How to restrict the user from making any changes in Sales order- item level

Hi to all
How to restrict the users from making any changes in sales order at item level if the same sales order is released by senior user through status profile.

Anish Parikh
Edited by: anish parikh on Jan 24, 2008 5:16 AM

Hi Anish,
This can be achieved through the roles and authorization.
This can be done through the basis team. they can create user profiles and roles.
For the roles they assign some transaction codes so that they can view the only assigned tr. codes.
Like that ur requirement can be done.
Also u can prevent the user to change any fields in the sales order screen (VA02). for that please modify the authorisations.
Hope i answers.
Reward points if useful.

How to retrieve the data from SAP database.

Hi Pals,
How to retrieve data from SAP R/3 System to my third party software. I will make my query little bit more clear. There is a list of assets entered and stored in the SAP system. For example 3 mobile phones.
1) Mobile 1- Nokia
2) Mobile 2 - Samsung
3) Mobile 3 u2013 Sony
Now think I do not know what all assets is there. I have to retrieve the data and get it on my third party software. Just display the list of assets. Lets say SAP XI is also there. Now how will I map it and get the details.
Please give me step by step method.
N.B: Just to read the data from SAP database.
Please make the flow clear step by step.
Thanking you
AK

Hi,
You can use RFC or ABAP Proxy to make synchronous call with SAP.
Under RFC or ABAP Proxy Program you can get the data from SAP tables. Direct access to SAP Database is not preferrable even if its possible.
The better way to go for RFC or PROXY.
You will send the request from Third party system and the it will be as input parameters from RFC/ Proxy it will response based on it.
This got it all..

How to restrict the user from accessing other screens before submittingdata

Hi All,
I have some screens developed in Webdynpro ABAP and all these have been linked to Portal as pages. In Portal If i click on the link in detailed navigation i can see the corresponding screen on the right side. Now in one screen i have to input some data and submit the data, Now my problem is if i enter some data and before submitting the data if i click on any other link in the detailed navigation, that corresponding screen is opening and all the data of the previous screen is lost.
Can any one suggest me, how can i restrict the user from accessing other screens before submitting the data of that screen from portal perspective.

Hi Prasanna,
The pages can be restricted from the user access by using the ACL permission or you can restrict the page by making invisible in navigation area which you do not want to show to the user . Open the page properties and select navigation category in the drop down and select the Invisible in navigation area property to yes.By default this property is No.Change the property for all pcd pages which want to hide from user access.
Hope this helps you...

How to secure the users from deleting the work items

Hi all,
I have a question like this.........whether we could secure the users from deleting the work items by someone in the Project and also assigning a specific user to allow them to delete the idoc.
Please help me on this as this is critical.........
Thanks in advance
Chakri

One of t he possible way is, ask the basis team to create users as Service Users and you can determine whether the login user is whether a service or dialog user by using the a bapi BAPI_USER_GET_DETAIL under the exporting parameter logondata with field USRTYP where if the logged in user is Service user then this field will be populated as S if the user is a dialog user then it will be populated as A.
Now in more efficient way of fixing this is get the list of users for whom you donot want to give the authorization of deleting workitems and assign the appropriate role for all the listed users...
for roles and authorizations i hope the basis team is the right team to consult....

How to stop the users from saving the PO when there is error message

Hi Guru,
The error message had appeared but the user still can choose to hold the PO even though there is an error.
They do not want to let the user to have a choice to save the PO once there is an error.
Please advice where i can out this checking in.

Dear Sally,
As per OSS: Note 606728 - Hold Functionality of the PR & PO - Gaps.
The only way you can stop the hold functionality is by implementing the BADI: ME_PROCESS_PO_CUST.
I am copying the OSS text for your reference.
Summary
Symptom
It is possible in the system to create/hold a purchase order (PO) referencing a held purchase requisition (PR), but your business process requires that this not be possible in your installation.
Other terms
Hold, ME21N, ME52N, Parking, Save without Check, Held PR, PO referencing a held PR, Commitments, reduction of PR by a held PO
Reason and Prerequisites
Cause: The functionality is not provided in EA-PS 110.
Prerequisites : You must be on EA-PS 110 to implement this note
Solution
You can implement some customer BAdI's provided by SAP to get this functionality. Note that customer implementations of the BAdI's provided by SAP are upwardly compatible. The text that follows gives details of how to implement the customer BAdI's to accomplish this functionality.
This functionality might be provided in future releases. However, we cannot make any binding statements at this time in regard to the scope of this development and when it will become available.
The following are the steps required to implement the customer BAdI to give an error message when a user tries to create a PO referencing a held PR.
1. Go to transaction SE18. Enter the definition name as ME_PROCESS_PO_CUST. Select the push button display.
a) Choose Implementation -> Create.
b) Enter an implementation name. Choose Enter.
c) Enter a short text to describe the purpose of the implementation, then save the implementation.
d) Select the tab interface, then double-click the method "process_item".
e) Create a message to issue a message that the PR is on hold.
f) Enter the following code in the method:
                    DATA: LS_MEPOITEM TYPE MEPOITEM.
                    DATA : MEMORY     TYPE EBAN-MEMORY.
get current data from business object
                    LS_MEPOITEM = IM_ITEM->GET_DATA( ).
Check if the PO references a PR and check if the PR is not on hold
If the PR is on hold give an error message
                      IF NOT LS_MEPOITEM-BANFN IS INITIAL.
                        SELECT SINGLE MEMORY INTO MEMORY
                        FROM EBAN WHERE BANFN = LS_MEPOITEM-BANFN
                                    AND BNFPO = LS_MEPOITEM-BNFPO.
                        IF MEMORY = 'X'.
                           MESSAGE E900(ZM). "The message that you have created in step 6
                        ENDIF.
                    ENDIF.
g) Activate the implementation.
2. If you do not want to let the user put the PO referencing a held PR on hold, you have to also implement the BAdI ME_HOLD_PO. The following are the steps to implement the BAdI.
a) Go to transaction SE18.Enter the definition name as ME_HOLD_PO and click on the 'DISPLAY' button.
b) Go to Implementation -> Create.
c) Enter an implementation name, then choose Enter.
d) Give some short text to describe the purpose of the implementation, then save the implementation.
e) Select the tab interface. Double-click the method IS_ALLOWED.
f) Enter the following code in the method:
                    DATA : IM_BEKPO_WA TYPE BEKPO.
                    DATA : MEMORY TYPE EBAN-MEMORY.
                    *-Look if the PO refers to a Held PR
                    LOOP AT IM_BEKPO INTO IM_BEKPO_WA
                           WHERE NOT BANFN IS INITIAL.
                             SELECT SINGLE MEMORY INTO MEMORY
                             FROM EBAN WHERE BANFN = IM_BEKPO_WA-BANFN
                                        AND BNFPO = IM_BEKPO_WA-BNFPO.
                             IF MEMORY = 'X'.
                    *-Do not allow the PO to be kept on hold
                    *-if the PO is refering a held PR
                               CH_ALLOWED = ' '.
                              ENDIF.
                    ENDLOOP.
g) Activate the implementation.
I hope it helps.

How to delete the data from SAP R/3 DB table from BW

Hi,
I am facing an issue... I have populated the data into custom r/3 DB table by running a user exit.I am getting the data and loading(Full Load) it in BW ODS. But my problem is when i rerun the user exit it is giving me a short dump saying "SAPSQL_ARRAY_INSERT_DUPREC". when i delete the enteries of DB table it is working fine. But this fine in development.but i production i cannot do this.So i want to delete the DB table enteries by an ABAP program and call this ABAP program using Process chain when my ODS data LOAD is successful. How to go About this.
P.S: I want only to delete the DB table enteries not the DB table.....
Thanks and Regards
Sairam phani

Sairam,
why don't you just add the code for deletion of records into that user exit, so it would first delete entries and then write new ones.
Alternatively, you could use a Process Chain to trigger an event in R/3, and by that event a scheduled job would run, deleting entries from that table.
As I don't know details of the solution you're implementing, that's all I can think of now.
Cheers,

How to Restrict the users from changing the Default variant of report.

Hello everybody,
The requirement is to restrict the users to save and overwrite the default layout variant (Layout for higher managenet)set for the report, but at the same time they should be able to change and save the other layouts for which they are having access.
I have written the logic in the program which is working fine for all the scenario when we execute the report. But the logic doesnt work if the user is selecting the layout on the output screen of the report.
for e.g if the user runs the report using the layout varaint for which he is having the authorization then he gets the all 4 options so he then he can select the layout for which he is not authorized and he can overwrite.
i have debugged and check as i have found that after the report output is shown all the layout paramater is controllled by the statndard SAP objects.
Can anyone help me out in this issue.
Thankyou in advance.
*to get the default layout variant.
w_save = 'A'.
if p_vari is initial.
    clear disvariant.
    disvariant-report = sy-repid.
    w_variant = disvariant.
    call function 'REUSE_ALV_VARIANT_DEFAULT_GET'
      exporting
        i_save     = w_save
      changing
        cs_variant = w_variant
      exceptions
        not_found = 2.
    if sy-subrc = 0.
      p_vari = w_variant-variant.
    endif.
endif.
*logic to check user authorization to change the layout setting.
if p_vari = c_layout.
    if not sy-uname is initial.
      select single * from agr_users
              where agr_name = c_role
              and   uname    = sy-uname.
      if sy-subrc = 0.
        w_save = 'A'.
      else.
        w_save = ' '.
      endif.
    endif.
endif.
Regards,
Satish.

Hi Maine,
Thanks for your reply.
As you mentioned for your own program, you can control the parameter "I_SAVE", when calling "REUSE_ALV_GRID_DISPLAY".
so already i have use the same logic and control the parameter through I_SAVE and here i am calling method ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY instead of "REUSE_ALV_GRID_DISPLAY".
and it works fine when we execute the report but the logic doesnt work when the user tries to change and save the layout variant on the output screen of the report.

Satish

How to get The users from a Collaborator that is type Group.

Hello, I'm trying to get the users (and their emails) of a collaborator inside a Master Agreement that is type group.
I've tried the following methods:
1- Using a IBeanHomeLocator to get the GroupIBeanHomeIfc (with the static variable of sHOME_NAME) and then trying to get the Group with the DocumentId that the colaborator's method (getDocumentId()) returns and the GroupIBeanHome method findGroup().
The result was null
2 - Using exactly the same method as before, but instead of using the DocumentId, I did a query, in order to get the field USER_GROUP_OBJECT_ID, to get the Id of the group.
The result is still null.
I'm not sure if there is a direct way to get it, or if i'm misusing the GroupIBeanHomeIfc.
Thanks in advance!

Hi Oscar,
In the document collaborator class there is a method getCollaboratorType() which returns CollaboratorTypeEnumType and there are certain values assigned to them.
user - A user collaborator
group - A group collaborator
contact - A user contact
So, hashcode of 2 returns the group.
Please have a look in to the below code.
collaborators = doc.getCollaborators();
     if(collaborators.size() > 0)
        collabIter = collaborators.iterator();
          while (collabIter.hasNext())
             member = collabIter.next();
             collabType= member.getCollaboratorType();
             hashValue= collabType.hashCode();
                if(hashValue==2)
                          collabName= member.getDisplayName();
                          throw new ApplicationException("collabName:" +collabName);
In the above code collabName returns the name of the group, with this you can search for the specified group using IbeanHomeLocator for group and then you can get the members in it and their mail Id's
Hope it helps you and let me know if you need any assistance.
Thanks,
Raj.

How to prevent the User from loading more than one seq file?

Hi,
I would like to prevent the tester operator from loading more than one test sequence. Any ideas how to do it?
Thanks
Rafi

Hi Marty,
Marty_H wrote:
Hello mhousel,
Testexec.exe by default loads the sequence files that were last open when it runs. It is often desired behavior to have multiple sequence files load automatically.
[Mark Housel] Maybe for some but certainly not for me.
This should be easily handled by TestStand without any problems. What do you mean by "chaos ensues"?
Certainly Teststand doesn't care a bit how many sequences are open. But, when my sequences open they initialize HW of the ATE associated with
that sequence file during the sequenceFileLoad callback. e.g. I allocate TELNET handles to a terminal
server that connects to multiple console within the system and als for
the UUT.
If a second sequence opens it knows nothing about the other sequence and again tries to open a TELENT session to the same port of the
terminal server and obviously fails, so my sequence reports that it
can't properly initialize the ATE HW. Bad juju!
Are your sequence files set to run automatically when they are loaded?
I guess so. Other than the trick of logging in as the special noExecution user and having special code in my sequence and modified Process Model I have no idea how to prevent a sequence fronm "runnin" when opened.
If you want to prevent Testexec.exe from loading multiple files, you should be able to close out one of the open files when it loads and that sequence file should not load in the future. I hope that helps.
The trick I read somewhere else of modifying the Testexec.uir file to never re-load a sequence file automatically seemes to have covered up solved the problem.
Thanks,
Mark

How to extract the data from SAP using Msaccess tool ?

Hi Experts,
Purpose u2013
Want to extract the data in a better way rather than using the T.code u2013 SE16
regards
Kedar Kulkarni

Hi,
Try this...
Please use the standard ABAP program "RIACCESS".
Before using the program "RIACCESS", you need to install the PS utilities, which are part of SAPGUI install CD.
It is available in the "\SAPGUI\PS directory".
Then do the followings :
1. Select transaction code SALE -> Systems in network-> Define RFC Destination.
2. You will need two RFC destinations (TCP/IP connections for the front-end workstation).
Setup the two RFC destinations PS_ACCESS_1 and PS_ACCESS_2 and you'll have to get them to point to wdpsastr.exe and wdpsatab.exe respectively.
3. Then execute RIACCESS and choose PS_ACCESS_1 to generate access tables.
The system must also be able to access the RFC-DLL files (librfc2.dll, librfc3.dll, librfc4.dll, librfc5.dll, librfc6.dll, vrfc.dll).
Please note that Access only supports tables with up to 255 fields.
