Differences between APO and R3 sysytem.

Hi everybody,
                    Can anyone list out the differences between the APO system and the R3 system.A detailed explanation will be helpful.

Hi,
APO
APO is the supply chain tool from SAP.
BW is the data layer for APO.
SAP APO is for Demand Planning and is a component of mySAP SCM. It enables dynamic supply chain management and which in turn includes applications for detailed planning, optimization and scheduling, allowing the supply chain to be accurately and globally monitored even beyond enterprise boundaries.
SAP BI is a reporting tool in SAP. It provides a complete view of the company. The solution is part of SAP NetWeaver and provides the tools needed to make the right decisions, optimize processes, and measure strategic success: data from all enterprise sources are merged effectively and can be comprehensively analyzed, business-critical factors can be monitored using external and internal benchmarks, the most important KPIs can be passed on to all the relevant forces in a company in real time, strategies can be rapidly adapted to changed market conditions, and the results of analyses can be graphically represented in a wide variety of formats, such as grids, graphs, and maps

What is APO and how it is related to BW
SAP Advanced Planner and Optimizer is a component of the mySAP Supply Chain Management solution that you use for planning and optimizing supply chain processes at a strategic, tactical, and operational planning level.
With APO - Simultaneous Material & Capacity Planning is possible, as against R/3 PP
APO Planning is capable of taking all the constraints into consideration with Planning for Capacities/Scheduling
APO Resource (workcenter in R/3) does a Capacity availability check before scheduling an activity, if capacity is not available, it finds the immediate next available slot & schedules the activity there. This is not possible with R/3

  • SNP planned order availability date difference between APO and ECC

    Hi,
    I have observed that SNP Planned order availability date is not matching between APO and ECC. Details are as follows.
    I ran SNP Optimizer with bucket offset of 0.5. After publishing the optimizer created planned orders to ECC, only start date is matching.
    Example:
    I am using PDS as a source of supply.
    Fixed production activity in SNP PDS is 1 day.
    GR processing time: 3 day
    After running optimizer planned order is created with dates explained below.
    Start date/time: 09.05.2011 00:00:00
    End date/time: 12.05.2011 23:59:59
    Availability date: 16.05.2011 00:00:00
    Because of bucket offset defined as 0.5 optimizer planned order availability is start of next monday.
    After publishing this planned order to ECC dates on the planned order is as follows.
    Start date: 09.05.2011
    End date: 09.05.2011
    Availability date: 12.05.2011
    I have not maintained any scheduling margin key in ECC. Also if I dont define the GR processing time, planned dates between APO and ECC always match. Can anyone explain the impact of GR time on the availability date.

    Venkat

    Hi Venkadesh,
    What's "state stamp"? Do you mean different time zone?
    note : 645597  mentioned by Nandha is very helpful:
    In standard, CCR will use duedate - "the available date of the output product".
    Nandha's words "In SAP APO, if the receipt date of the primary product deviates from the
    end date of the last activity of the order, the receipt date
    always identifies this as inconsistent. You cannot rectify
    inconsistencies of this type by using CCR."
    I guess in your PDS or PPM, the output product is not assigned to the End of the last activity. Someone changed it?
    Please CIF the PDS or PPM again.
    If you really want to apply a note, please use note 815509 as you're using planned order,
    and system will use order end  date in CCR instead.
    GR time is always considered. BR/Tiemin

  • Difference between APO and SCM

    Hello All,
        I am new to SAP...
        Can somebody tell me the difference between SAP APO and SAP SCM.....
    Regards,
    Mary

    Hi,
    SAP Advanced Planning and Optimization (APO) is the planning component of mySAP SCM, the supply chain management solution provided by SAP.
    SAP APO is used to make strategic, tactical and operational decisions and supports you in performing the following planning activities:
    Demand Planning (DP)
    Supply Network Planning (SNP)
    Production Planning (PP)
    Detailed Scheduling (DS)
    Deployment
    Transport Load Builder (TLB)
    Transport Planning and Vehicle Scheduling (TP/VS)
    Global Available-to-Promise (gATP)
    SAP's endeavor into the advanced planning solution market was with the name SAP APO. There are other APS solutions in the market from Oracle, Manugistics, i2 and a whole host of other companies providing specialized planning solutions
    Over the years SAP has brought the SAP APO solution under a wider umbrella called SAP SCM. Since version 4.0 of APO it has been called SAP SCM. So in the release strategy of SAP you will find SAP APO 3.1 followed by SAP SCM 4.0
    SAP SCM is a more complete solution that covers planning, networking, coordinating and execution. In addition to SAP APO, which is still the core of SAP SCM, there are other applications such as SNC (Supplier Network Collaboration - erstwhile ICH), SCEM (Event Management), EWM (Extended Warehouse Management) and SPP (Service Parts Planning)

  • Difference between zero and blank values

    Is there a way for the system to determine the difference between zero and blank values. One can have a zero allowed for the 0 value to actualy be there in the KF but is there a way that a macro can be written by which we can use the differentiation between the zero ( a value) and blank (no value) in the KF
    I have tried to look for an explanation on the service.sap.com and sdn but was not able to find anything.
    Thanks in advance

    Thanks for your reply. You mentioned something about the "fixing" setting that could make the "0" displayed in the planning book. Could you elaborate?
    Also, in the post from user "APO APO" on 5/8, the author seemed to indicate they could see the "0" in the planning book, as quoted below:
    "I have already made the zero allowed arrangement for that in the planning area and can see the 0 values in the planning book but I am not being able to make the macro get the results."
    I just want to find out if there is any way the user can visually distinguish b/w the "0" and blank values. If not, it'll be very confusing to the users. I understand the macros can distinguish b/w them.
    Thanks in advance.

  • Difference between PDS and PPM and which one should be used for SNP /ppds?

    Hi Gurus,
                 Just wanted to know what are the difference between PDS and PPM ?
    1. For what industrial products we use PDS and PPM in SNP and PPDS?
    2. which one can be refered to clients?
    Please let me know it will be really great if anyone let me know the answers
    Thanks & Regards,
    Raj

    Hi Rajkumar,
    I have given below the detailed comparative account of PDS Vs PPM. Please copy and put it in an excel sheet in different columns and then read which is easy to understand.
    PDS
    1. Production Data Structure (PDS) in APO 3.1 & Run Time Object (RTO) in 4.0 and above versions
    2. Master Data Object
    3. Useful for scenarios where the compoenent has got different validity periods
    4. Used as Master data Basis for Planning in SAP-APO
    5. Contains active Master data from iPPE (Integrated Product and Process Engineering) generated from a production version
    6. PPDS PDS & SNP PDS can be used as master data for planning
    7. Change Management, variant configuration & Phantom assemplies are supported in PDS
    8. Sub-contracting in SNP is fully integrated with R/3 is supported in PDS
    9. Direct transfer of SNP PDS from R/3 is possible
    10.Rapid Planning Matrix can be generated
    11. Not possible to maintain PDS directly in APO and can be used only in combination with R/3
    12. The transfer of data changes is simpler
    13. Not possible to create alternate SNP-PDS in std system for different mode combinations
    14. PDS can be automatically generated from two sources ie R/3 and iPPE
    PPM:-
    1. Production Process Model
    2. Master Data Object
    3. Cannot be used for scenarios where the component has got different validity period
    4. Used as Master data Basis for Planning in SAP-APO
    5. Contains active Master data generated from the combination of routing (BoM & receipe) and production versions
    6. PPDS PPM & SNP PPM's can be used as master data for planning
    7. Not supported by PPM
    8. Not supported by PPM
    9. Not possible here. SNP PPMs will be generated via PPDS PPMs
    10. Not possible
    11. PPMs can be directly created in APO and can be modified without R/3 also.
    12. Little Complex when compared to PDS
    13. Alternate SNP-PPMs can be easily created
    14. PPM can be generated automatically generated only from R/3
    PDS is used in industries wherein there are multiple components or assemblies having diffeent production versions whose validity periods are different.  PPM is being used typically in process industries, chemical industries.  PPM is very simple in its usage and very flexible in operations in terms of modifications at APO level and can be referred to client depending on the business requirement

  • Difference between PPM and PDS, PPDS and SNP

    Hello Gurus,
    I'am a beginer to APO so could you please let me know about the difference between PPM and PDS? Also the difference between SNP and PPDS/
    giri

    Production Version in ECC can be transferred to APO as:
    PPM - Product Process Model or,
    PDS - Product Data Structure
    These form the basis master data for Planning in APO
    SNP - Supply Network Planning & PPDS - Production Planning and Detailed Scheduling are two Modules in APO for planning purpose.

  • Difference between Null and null?

    What is the difference between null and NULL?
    When is each used?
    Thanks,

    veryConfused wrote:
    There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

  • Difference between GUI_UPLOAD and WS_UPLOAD

    Hi,
    Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
    Thanks,
    Satish

    I would suggest to always use the GUI_UPLOAD.  I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
      data: filename type string.
      filename = p_file.
      call method cl_gui_frontend_services=>gui_upload
             exporting
                  filename                = filename
                  filetype                = 'ASC'
             changing
                  data_tab                = iflatf

  • Difference between char and varchar, also the difference between varchar2

    Hi,
    Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

    Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
    Example 1:
    SQL> create table tchar(text1 char(10), text2 varchar2(10))
    2 /
    Table created.
    SQL> insert into tchar values('krystian','krystian')
    2 /
    1 row created.
    SQL> select text1, length(text1), text2, length(text2)
    2 from tchar
    3 /
    TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
    krystian 10 krystian 8
    Example 2:
    create table tvarchar(text varchar(10))
    SQL> select table_name,column_name,data_type
    2 from user_tab_columns
    3 where table_name = 'TVARCHAR'
    4 /
    TABLE_NAME COLUMN_NAME DATA_TYPE
    TVARCHAR TEXT VARCHAR2

    Hi,
    They are both used for 10Gig interfaces.  The difference is the connector type.
    SFP+ is LC and X2 is SC.
    You can not put an SFP+ into an X2 slot or X2 optic into a SFP+.

  • Difference between ok_code and sy-ucomm

    Hi,
    Can any one tell me the difference between ok_code and sy-ucomm

    Hi,
    Actually OK_CODE and SY-Ucomm are the same. But experts suggest use of OK code for following reason:
    In each PAI event that a user triggers by choosing either a pushbutton on the screen or an element in a GUI status, the corresponding function code is placed into the system field SYST-UCOMM or SY-UCOMM and placed in the OK_CODE field (as long as the function code is not empty). Empty function codes are placed in neither the SY-UCOMM field nor the OK_CODE field.
    In your ABAP programs, you should work with the OK_CODE field instead of SY-UCOMM. There are two reasons for this: Firstly, the ABAP program has full control over fields declared within it, and secondly, you should never change the value of an ABAP system field. However, you should also always initialize the OK_CODE field in an ABAP program for the following reason:
    In the same way that the OK_CODE field in the ABAP program and the system field SY-UCOMM receive the contents of the corresponding screen fields in the PAI event, their contents are also assigned to the OK_CODE screen field and system field SYST-UCOMM in the PBO event. Therefore, you must clear the OK_CODE field in the ABAP program to ensure that the function code of a screen is not already filled in the PBO event with an unwanted value. This is particularly important when the next PAI event can be triggered with an empty function code (for example, using ENTER). Empty function codes do not affect SY-UCOMM or the OK_CODE field, and consequently, the old field contents are transported.
