What is a logical component & Solution

Hi gurus,
I have a very basic query on Sol Man terminology.
1. Logical Component - what is it?  Why its used?  What is its relevance to the satellite systems I would add to Sol Man system?
2. What is a Solution?  How is it related to the satellite systems?
Any help would be help.
Thanks
Abdul

Hi Abdul,
A logical component is a placeholder for a true component in your system landscape.
For instance SAP R/3.
To this logical component you link your satellite systems with their details.
For instance Dev SAP R/3 Client 100, Production SAP R/3 etc.
The logical component you use everywhere you need to reference your R/3 system.
This way, if your actual R/3 satellite system location or version changes you only have to change it in one place.
A solution contains the systems in your system landscape. Which systems you combine in one solution depends on your business processes. All systems that are touched by your business processes are combined in one solution. The business processes refer to the satellite systems through the logical components.

  • Solman_setup - Solution / Logical Component

    hi,
    I just completed Solman 7.1 upgrade. Currently working on solman_setup. Just realized that the at start the "Specify Solution", it by default used another Logical component and Solution. However, we are using another logical component/solution in all work center applications.
    Need some help, if this is possible to reassign the logical component/solution so that the solman_setup are applicable to another one?
    Can it be possible / should necessary to Redo the solman_setup?
    Would appreciate your feedback.!!
    Thanks,
    RajS

    Also under the trans  SOLMAn_SETUP //  
    You have to "simply" run again in solman_setup all activities that are
    flagged as "Update Needed" (for System Prep & Basic Config).
    Concerning the Managed systems, mainly (as far as concerning RCA) the
    solman_setup -> Managed system configuration doesn't need to be
    re-executed.

  • Logical component in SolMan using SMSY

    Hi,
    What is a logical component and why is it necessary. Why do we create that in our solman system for the landscape.
    Also i was going through one tutor in rkt-solman link for creating logical component. It shows for a r/3 system. Is the same selection valid for the Netweaver component also.
    Help required and shall be appreciated as well.

    Hi,
    First of all thanks for the reply.
    One thing is while i create a new system with assistant, and select the product as netweaver and proceed it asks me to select the main instance. What is this main instance. Say for me the system i am adding is the one having J2ee engine and portal plus trex on it. It doesnot have the ABAP instance. So what should be my selection. Should it be only WebAS Java or java + portal + trex.
    Secondly what i did was i selected java and EP and Trex and proceeded. It didn't give me the option of entering the System Number and Message Server. In the next screen the only option i had was to assign logical component. If i select the box then it asks for client but the box for client is disabled.
    Don't know what to do. Also RFC anyway is required. In such a case what should be the case. How should i create those RFC's and what RFC's are required for the same.
    Lot of questions. Hope to get the detailed reply.
    Answers will be rewarded nicely.

  • XI 3.0 and BW 3.5 system type/logical component in Solution Manager

    We are in the process of performing an upgrade for ERP 2004, XI 3.0 and BW 3.5. Initially this is being done in the sandpits. All systems are configured and connected our Solution Manager to download the packages.
    We are unable to determine what type of system the XI 3.0 and BW 3.5 should be configured under. For example, previously we had an issue where ERP was configured as ECC 5.0 rather than ERP 2004. This was causing an issue in MOPZ where the upgrade option wasn't visible in a maintenance transaction. The same issue is now happening for XI and BW.
    Please advise on the system type (logical component to use) for XI 3.0 and BW 3.5 in Solution Manager as SAP have made it very confusing. Currently both are under type Netweaver 04.
    Regards,
    -Rohan

    Hi
    I believe that SAP hasn't upgrade option for BW 3.5, Check link:
    https://service.sap.com/solman-mopz
    Upgrade
    a "straight" upgrade for SAP Business Suite (upgrade from SAP ERP 2004 to SAP ERP 6.0, for example) is not supported by Maintenance Optimizer
    Upgrade with an Installation of an Enhancement Package is supported for SAP ERP, SAP SCM, SAP SRM and SAP CRM

  • Solution Manager - Logical Component for SAP Netweaver EHP2

    Hello,
    I installed the newest SAP Netweaver Ehp2 (with usage type AS ABAP only) for a future integrating with BI_CONT (SAP BI requirement). So... what I want to know is... I want to do an update of support packages to the latest Stack (SPS) and in this product version (NW EHP2) the latest stack is stack 06 !! But I ´m facing with a problem which is, because I have to maintain this system in Solution Manager (for Maintenance Optimizer activity)...so what I want is configure this new system on Solution Manager Ehp1 (with SPS 23) but in tcode SMSY I didn´t found this Product in Logical Components for I can apply this system to my Solution... I only see SAP Netweaver with EHP1 and not with EHP2 which is the version that I want to apply this new system. (This is mandatory task, because without it, I will not be able to download the support packages for NW 7.0 EHP2)
    Tell me two things... first if this level version of Solution Manager that I have here (SPS 23) have this product in logical components, and two... if not it, is necessary to raise the level of Solution Manager support packages (to latest stack SPS 25) for I can see that logical component SAP Netweaver EHP2?!
    Thank you very much
    João Dimas - Portugal

    Hi João,
    You can verify if the EHP2 is available (if) in your system, this can be done once you are in SMSY -> Product Definitions -> SAP Netweaver where you should able to see the EHP2. If so, then it's a matter of marking the leading Product & Product Version under the Header Data ->Change Product Assignment where you can use the drop down arrow to select the Product and Product Version. If it's not available, then by checking the 'Free Product / Select Product Version' then use the drop down arrow to select the product & Product Version, once you selected that then click on copy and mark that as active and save.
    Then you need to create a new logical component in System Group & logical Component under SAP Netweaver, then assign the system to the logical component. Once this is done you can use the logical component in a solution and create a maintenance transaction.
    I hope this help you to proceed further, thanks.

  • How To create a maintenance project - logical component missing?

    Hi experts,
    we plan to activate ChaRM in our Landscape.
    We don't have created a maintenance project in solution_manager cause there is a logical component missing.
    I followed the instructions of the tutorial on  https://websmp206.sap-ag.de/~sapidb/011000358700006932702005E.sim (Creation of a maintenance project).
    I recognized there is the logical component "ZCHANGE REQUEST MANAGEMENT" missing.
    This seems to be a modified origin SAP Component.
    Does anyone know where to find these component?
    Maybe with informations what has to be changed for the Z*copy or is this only a 1:1 copy?
    Does anyone have a detailed document for configuring ChaRM on SolMan 7.0 (Mailadress is visible on my business card)
    thanks in advance
    kind regards
    Thomas
    Helpful answers/documents will be rewarded, surely!

    You need to set up your solution and therefor define a logical component in SMSY. For instance the logical component might consist of your ERP E, Q and P systems.
    This logical component is added to an SMI Project. It basically tells the SMI project which systems are involved in the process. After that you will have to create an IMG project, CTS project, release the SMI project to the Change Request Management and generate Maintenance Cycle and Task List (this is all being done in SOLAR_PROJECT_ADMIN).

  • Managing more than one logical component in SMSY Current System Assignments

    Hi,
    I have a problem with managing logical components in TA SMSY in my Solution Manager System, in the section "System Groups and logical Components". I want to maintain more than one logical System e. g. from Type Application Server ABAP --> SAP NETWEAVER APPLICATION SERV.
    That means e. g. i want to maintain 2 or more Demo Systems from different Servers or Instances of the same Product Version in the same logical Component .
    What I want to know is, is there a way to display these logical components in tne  "Current System Assignments" - View in that form
    Logical Component is e.g. : SAP NETWEAVER APPLICATION SERV
    product/main instance is   : SAP NETWEAVER [Application Server ABAP]
    Product Version | Development System | Demo System | Training System | Production System | ...
    |--|||--
    |
    SAP NW 7.0        |                                         | ZB1: 100           |                               |                                     |

    Thanks for your quick answer,
    but i have to say, that this is not exactly what i've been lookin for.
    What I need in my System Landscape is to have each demosystem as a logical Component from the same type (e.g. SAP NETWEAVER APPLICATION SERVER ABAP).
    So that in Change Management in a Maintenance Optimizer Transaction i can choose between each demo system in my System Landscape (from the type SAP Netweaver Application Server ABAP) that i will maintain in Maintenance Optimizer, e.g. download a new SP Stack.
    My Intention is to create new logical components from type  SAP NETWEAVER APPLICATION SERVER ABAP in my Namespace e.g. ZSAPNW01, ZSAPNW02, ... and to maintain the types of systems (Demo, Development, Training etc ...) for each logical component.
    Is this the only Possibility?
    Or do i can also display my logical components the way i descriped beyond?
    >
    Product Version | Development System | Demo System | Training System | Production System | ...

  • No monitors pulled for self defined logical component

    Hi,
    I have defined a system landscape in smsy and created solution landscapes in the sm. For some systems I had to create a new logical component.
    My problem: Although RFC destinations work fine, for all systems within the new logical component no monitors are pulled out of rz20.
    If I use a SAP-defined logical component it works.
    I use Solution Manager 3.2.
    Is there any documentation for this problem or does anybody know a solution for this?
    Thank you and best regards,
    Tim

    Hi again,
    I thought about the problem and tried several things. The problem is not the self defined logical component. The problem is the product definition. I can`t monitor systems, which I created as product SAP ERP in smsy. The check "SAP System ..." doesn`t appear when I want to setup System Monitoring.
    Does anybody have an idea what I do wrong?

  • Logical Component after upgrade

    Hi,
    I have slight confusion.
    We upgraded our SCM system from SCM 7.0 to SCM 7.01 (Ehp1). now our product version is "EHP1 FOR SAP SCM 7.0"
    and Product instance is "SAP SCM ENHANCE PACKAGE"
    in logical component which is used in Charm and monitoring.
    following are the  current details
    logical componenet:  Z_SCM
    Product/Prod. Instance SAP SCM [SCM Server]
    product version: SAP SCM 7.0
    Now i want the correct assignment of logical component which includes product version and product instance.
    How do I get same logical component name with new product instance, so that my charm and monitoring is not affected.
    Its same case for PI.  from SAP netweaver PI(7.11) to SAP Netweaver (7.3)
    BR,
    Shyam

    Hello Shyam,
    Sorry, you are correct, the logical template needs to be copied from a system group and SAP SCM 7.0 and SAP SCM 7.0 EHP
    are in different system groups, and you won't be able to pick up your SCM 7.0 systems in the SCM 7.0 EHP logical.
    What might be possible, and I don't know if it would be practical is to retire  Logical Z_SCM that was based on SCM 7.0, and by retire I mean remove, and then create the same nameed Logical Z_SCM but copied from the template of SCM 7.0 EHP, then you could see your SCM 7.0 EHP systems and pull them into the new logical Z_SCM and add that back to the solution.
    I have not tried this, but if you have a test environment you could try this to see. Logically it should work. Its certainly something you could prove or disprove on a test system.

    Paul

  • Can't assign system to logical component

    Hello everybody,
    I try to configure my Maintenance Optimizer. I have created a system with main instance SAP ECC Server. In view Landscape components i can see my system in node systems->sap erp. When i try to assign a Logical component SAP ECC an a massage "Logical component SAP ECC cannot be assigned to this main instance" is displayed and component is not assigned.
    What have I wrong made? What should I check/configure?
    Regards
    Bogdan

    If you go to help.sap.com and SOlution Manager and look for the assign logical components menu item you will find instructions on this. Basically from SMSY click on the system then on top left menu tree select "Other Objects"
    when the popup comes up enter the system id in the "System field"
    Then at the bottom of that popup you should see an icon like to pieces of paper called"Intalled product versions" click on that and you get another popup to show products installed on the box. If it is not listed in the bottom , you can use the top section to select the product using free product selection , then you should see this error disappear as you have identified the main instance it is talking about and furthermore you should be able to then assign it to a logical component

  • What is the logic for 2LIS_17_I3HDR to pick a order as completed on time?

    Hi, Experts:
    I am working on PM using 2LIS_17_I3HDR to load data. In 2LIS_17_I3HDR, there is a field called "orders completed on-time". I am wondering what is the logic for 2LIS_17_I3HDR to identify if an order was completed on time. I would assume it compares some kind of completion/finish date with a planed/schduled comletion/finish date. Would someone please tell me what fields in what table or in transaction IW39 DOES does 2LIS_17_I3HDR  use for this?
    Many thanks!

    Hi, Ram:
    Thank you for the reply!
    The key figure is ZHLAFIH_TGERL (Number of On-time Closed Orders). I saw some SAP programs refering to its component type "DZHLAFIH_TE" too.

  • Monitoring "check aborted jobs" not possible - Logical component issue?

    Hy Experts,
    we are facing a problem setting up system monitoring in our Solution Manger system.
    We want to check if a specified job is finished sucessfully - if it is aborted we want to receive a mail.
    In another system the monitoring as described is fully functional.
    In this scenario we are facing a problem:
    Error Text:
    The logical components SAP NW REDWOOD CRONACLE and Z_SYS_MONI have different products
    Message no. SOLAR170
    Diagnosis
    This component change can prevent the processes and scenarios which you have copied from the BPR into the "Structure" tab, in transaction SOLAR01, from running in the assigned system, or assigned transactions, IMG activities, etc. may not exist in these systems. For example, transactions or IMG assignments copied into the previous product context do not yet exist in the project.
    If the same systems are assigned to the new and old logical components, the change is not critical.
    System Response
    The system sends a warning and accepts the change, but no data is automatically converted or adjusted.
    Procedure
    If you are unsure whether your assignments will still be in the component systems after the component change, perform the function "Environment - Refresh Buffer" in the transaction SOLAR01. Errors in this program are objects which do not exist in the system.
    Actual product of the logical component "Z_SYS_MONI" is ECC5.0.
    The other (working) is using the logical component "SAP NETWEAVER APPLICATION SERV" instead of the above used "SAP NW REDWOOD CRONACLE "
    How can this error be fixed OR
    How to monitor jobs with logical component ecc5.0?
    Any help will be rewarded!!!
    Thanks in advance
    Tom

    Detailed Info:
    The working solution is assigned to ECC 6.0 AND to SAP Netweaver 7.0 (2004s).
    The selection in business process repository - it-platform - monitoring is assigned to SAP Netweaver 7.0. -  but we have ECC5.0 - even if I create the system/logical component new under Netweaver 2004 (6.40) it won't work
    It seems not to be possible.
    But how to monitor a job in ECC5.0 - think it is possible.
    Any ideas?
    Please help!
    OK
    Seems not to be possible!
    Set to solved - but this is not the way to solve problems dear SAP

  • SAP Delivered Logical Component Inactive, SAP CRM 5.0

    I would like to use the SAP CRM 5.0 Logical Component as Delivered by SAP. The systems are already upgraded but I cannot seem to Acitvate this in transaction SMSY. CRM SERVER 4.0 is active and can be used.
    Anyone have any ideas?

    Hi Romina,
    Yes you can install it later not just for CRM but for any SAP Solution from the Business Suite or SAP NW04s.
    You have to start JSPM and select Install Additional Usage Type and select JCRM.
    Make sure after you install the new type to check your software components
    http://HOST:5XX00/sap/monitoring/SystemInfo. to see if all your components are in the correct stack.
