  • Best practice for standard security role

    Hi, I'd like to know which is the best practice for standard role use, some people tell me that a standard role should never be used, that a copy must be made and assign the users to the copy, but then, why should SAP bother creating the standard role?

    They are provided as a template for you, and you can copy them into a different namespace and make changes there before generating the profiles and authorizations.
    Why you should use a copy of them is because SAP will also update them sometimes. If transactions change in the standard menues with SP's and upgrades, then you will find them in transaction SU25.
    If you do a search on "standard AND roles" in the SDN then you will also find more detailed infos and opinions on the use of them.

  • Is there any best practice or standard for database object naming ?

    Hi
    Thank you for reading my post
    is there any standard or best practice for databse objects naming ?
    for example how should we name columns of a table ? should it be like TOTAL_VOTE or TOTALVOTE and many other items.
    Thanks

    what does oracle suggest as a naming schema for tables , fields , views. indexes , tablespaces , ... If you look at the data dictionary you will see that not even Oracle keeps rigidly to any specific standard, although there are tendencies :)

  • Best Practices for standardizing long text for EP GUI version

    Hello, I have a question that is related to standardizing best practices for all portal applications that use EP
    1) The portal team has recommended activating the GUI version from portal to allow the long text to have the same features as the standard GUI.  Since this solution is per transaction, we will need to identify what transactions need to have this temporary solution built in.  Also, business users will need to remember which transactions they will access via portal or GUI.
    (2) Even though the long text function is activated via GUI per transaction, the system will prompt a message of u201CRuntime Error!  Program C:\Program Files\Microsoft Office\OFFICE11\WINWORD.EXEu201D.  This may create frustrations to the users each time they maintain the long text.  The risk of this may be losing the use of long text throughout the maintenance orders, production orders, notifications, material masters, equipment masters, maintenance task lists, production routings, etc.
    All feedback welcomed
    Thanks Mark

    I found the solution, make everything in Illustrator (well text anyway) at a big size then bring it ibto Photoshop in a dicument 1024 x 576 (so no widescreen pixel ratio) then when saving document bring size of Image to 720 x 576 then you get great anti aliased pictures.
    Solved.

  • Best Practice, naming conventions and Ownership of accounts NEWBIE

    Hi Guru's please be gentle with me, I'm a sales manager in the UK and have been asked to check for best practices in naming accounts and who should own accounts in CRM 2011?For example I have Accounts with several sites and many contacts? How should I name
    these and who should own these? The office manager or the sales account manager that handles sales directly?
    Please help, I'm getting stressed. I think these are very simple for such a bunch of super gurus...

    Hello iBrummie,
    Regarding the Accounts and their sites, you can always use accounts and sub-accounts. To achieve this you should create the main Account in CRM and afterwards you can create the sites using the account entity as well and afterwards linking them with the
    main account using the "Parent Account" lookup field.
    About the ownership, CRM's security model works essentially with:
    Business Units
    Teams
    Users
    Security Roles
    This depends entirely on the way your company works but what I would do (assuming that the accounts information is shareable in your company) is to make the sales accounts the owners of the records and provide read/write access at a business unit level to
    the office managers.
    Here is some more info on the matter:

    How role-based security can be used to control access to entities in Microsoft Dynamics CRM
    Please mark as answer if I managed to help you.

  • Naming convention best practice for PDB pluggable

    In OEM, the auto discovery for a PDB produces a name using the cluster as the prefix and the database name suffix, such as:
    odexad_d_alpcolddb_alpcolddb-scan_PDBODEXAD
    If that PDB is moved to another cluster, I imagine that name will not change but the naming convention has been violated.
    Am I wrong and does anyone have a suggestions for a best practice naming the PDB's

    If the PDB moves to another cluster, OEM would auto-discover it in the new cluster.  So it would "assign" it a new name. 
    As a separate question, would you be renaming the PDB (the physical name) when you move it to another cluster ?

    Now we need to publish our services on the internet. I am looking for the security mechanism that I should apply in order to make the services secure. I may even like to verify that the request invoking service A is only coming from specified context.One approach we followed at a customer :
    - SOA was installed within internal firewall zone
    - A F5 BigIP Load Balancer was setup in DMZ. This load balancer terminated one way SSL connections coming from service consumers over internet. The load balancer forwaded the request to a pool of apache of web servers within DMZ
    - The Apache web servers had a redirection rule which forwarded the request to the soa server ports within the internal firwall zone. The internal firewall was opened to allow connections between apache web servers and soa server ports.
    - WS Security Username token/plain text password was used for message level security at the soa services layer.
    Some alterations you can do :
    1. enforce 2 way ssl and make load balancer to validate the CN of the client certificate. This can make sure only authorized clients are to make calls to the service
    2. OR setup some sort of IP filtering at DMZ firewall i.e. allow traffic only from authorized clients IP addresses to the load balancers virtual address for this specific service.

    Dear,
    Usually the role nomenclature is for the company as a whole
    Hence the std way is as below
    XX- 2 leter to repsenet the module
    XXXXXXXXXXXX-To represent the function(example-phy inv)
    XXXX-to repsent the plant it is applicable
    XXXX-to present- is it create/change/display/execute....
    XXXX- to repsent the variant
    hence it is as below
    Role is as below
    XX:XXXXXXXXXXXX:XXXX:XXXX:XXXX

    Hi Gurus,

         GT_ ,  GS_ ,  LT_  ,  LS_   ??????? 
    Regards

    Hello
    I use the following naming conventions:
    - G = global variable
    - L = local variable
    - T = internal table
    - S = structure
    - D = field
    That's how the combinations look like:
    - GT_ITAB     = global itab
    - GS_STRUC = global structure
    - GD_FIELD   = global field
    - LT_ITAB     = local itab
    - LS_STRUC = local structure
    - LD_FIELD   = local field
    Function module parameters have to stick to the following rules:
    - I = importing
    - E = exporting
    - [C = changing -> never used]
    - IT_ITAB = imported table type (itab)
    - IS_STRUC = imported structure
    - ID_FIELD   = imported field
    - ET_ITAB = exported table type (itab)
    - ES_STRUC = exported structure
    - ED_FIELD   = exported field
    Depending on their semantics TABLES parameters look like:
    - IT_ITAB = imported data
    - ET_ITAB = exported data
    - XT_ITAB = changing data (import & export)
    Here are the conventions for FORM routine parameters:
    - UT_ITAB = using itab (data are usually treated like constants; no changes will be transfer - although possible - to the calling program)
    - CT_ITAB = changing itab (if it is semantically an exporting itab then one of the very
    first statements in the routine is: REFRESH ct_itab. )
    - US_STRUCT
    - UD_FIELD
    - CS_STRUCT
    - CS_FIELD
    Conventions for class/interface parameters:
    - IT_ITAB = importing table type
    - IS_STRUC = importing structure
    - ID_FIELD = importing field
    - ET_ITAB = exporting table type
    - ES_STRUC = exporting structure
    - ED_FIELD = exporting field
    - RT_ITAB = returning table type
    - RS_STRUC = returning structure
    - RD_FIELD = returning field
    Conventions for class/interface attributes:
    - MT_ITAB = table type
    - MS_STRUC = structure
    - MD_FIELD = field
    - MC_CONST = constant
    <b>Question</b>: Are there any advantages of such elaborated naming conventions?
    My answer to this question is: Yes, definitively.
    I believe that the advantage of semantically differentiating TABLES parameters of function modules is quite obvious:
      CALL FUNCTION 'Z_BAD_NAMING'
        TABLES
           itab1 = ...
           itab2 = ...
           itab3 = ... .
      CALL FUNCTION 'Z_GOOD_NAMING'
        TABLES
           it_itab1 = ...
           et_itab2 = ...
           xt_itab3 = ... .
    I also believe that my naming conventions clearly enhance <b>readability </b>and <b>maintainability </b>of my programs.
    Regards

  • Project naming best practices

    hi
    the naming conventions for coding Java applications are clear to me. I'm  wondering what the best practices are for naming Java projects e.g. when creating a new project in NetBeans IDE or in BitBucket?
    thanks.

    the naming conventions for coding Java applications are clear to me.
    They are? What are they? Different orgs have their own naming standards. Other people have to be able to read, understand, maintain and enhance your code so standards are important.

    No one but your own business users and IT team even cares what you name your projects.

  • Best Practice : Creating Custom Renderer for Standard Component

    I've been reading the docs and a few threads about Custom Renderers. The best practice seems to be to create a Custom Component where you need a Custom Renderer. Is this the case?
    See [this post|http://forums.sun.com/thread.jspa?forumID=427&threadID=520422]
    I've created several Custom Renderers to override the HTML provided by the Standard Components, however I can't see the benefit in also creating a Custom Component when the behaviour of the standard component is just fine.
    Thanks,
    Damian.

    It all depends on what you are trying to accomplish. Generally speaking if all you need is for the user interface output to be changed then a renderer will work just fine. A new component is usually made in order to provide some fundamental change in server side functionality not related to the user interface. - Ponderator
