Fiscal Period and MM period.

Hi all,
Can somebody explain the difference b/w Fiscal Period and MM Period in business context. Detail explanation will be helpful.
thanks & regards,
Prashant Rathore.

Dear,
Fiscal Year Definition
Usually a period of twelve months for which a company regularly creates financial statements and checks inventories.
The fiscal year may correspond exactly to the calendar year, but this is not obligatory.
Under certain circumstances a fiscal year may be less than twelve months (shortened fiscal year).
Fiscal Year Structure
A fiscal year is divided into posting periods. Each posting period is defined by a start and a finish date. Before you can post documents, you must define posting periods, which in turn define the fiscal year.
In addition to the posting periods, you can also define special periods for year-end closing.
In General Ledger Accounting, a fiscal year can have a maximum of twelve posting periods and four special periods. You can define up to 366 posting periods in the Special Purpose Ledger.
What is the Use of Fiscal Year
In order to assign business transactions to different time periods, you must define a fiscal year with posting periods. Defining the fiscal year is obligatory.
You define your fiscal year as fiscal year variants which you then assign to your company code. One fiscal year variant can be used by several company codes.
You have the following options for defining fiscal year variants:
Fiscal year same as calendar year
Fiscal year differs from calendar year (non-calendar fiscal year). The posting periods can also be different to the calendar months.
You define your fiscal year variants in Customizing for Financial Accounting as follows: Financial Accounting Global Settings ® Fiscal Year ® Maintain Fiscal Year Variant (Maintain Shortened Fiscal Year)
MM Periods
Closing operations are periodic tasks and can be subdivided in FI as follows:
u2022     Day-end closing
u2022     Month-end closing
u2022     Year-end closing
The closing operations component helps you prepare and carry out the activities required for day-end, month-end, and year-end closing. For this purpose, the system provides a series of standard reports that you can use to generate evaluations and analyses directly from all of the posted account balance. The system helps you carry out the following:
u2022     (Time-based) accruals/deferrals of expenses and revenues
u2022     Creating the balance sheets and P&L statements
u2022     Documenting the posting data
Prerequisites
To carry out the closing operations in G/L accounting, you first need to carry out the closing operations in the subledger accounting areas you are using. These include:
u2022     Accounts receivable and accounts payable accounting
u2022     Inventory accounting
u2022     Asset accounting
u2022     Payroll accounting

  • Significance of IN PERIOD and FOR PERIOD

    Hi experts can any one explain me
    What is Retro calculation? and significance of IN PERIOD and FOR PERIOD while Retro calculation. If possible please explain with an example.
    Thanks in advance.
    vamsi.

    Hi,
    Retro calculation done automatically by SAP \
    weh you make changes in master data in back date retro run will take place.
    The retroactive accounting date or limit determines the exact date until which master data and time data can be changed in the payroll past. The retroactive accounting limit is based on the following values:
    1.Per payroll area (payroll control record): Earliest possible retroactive accounting period
    2.Employee hiring date
    3.Per Ijndividual employee the feild Earliest personal retroactive accounting date Payroll Status infotype0003.
    If the date set for each payroll area differs from the date specified for the employee, the later date is used.
    The most important thing to remeber is with regard to retroactive accounting limit for an employee is the hire date of the employee., one can neither run retro from a date prior to the Hiring date nor he can make any changes to master data prior to hiring date
    Retro is triggered in a payroll if u hav done master data change of an employee. This means 1) Any change in an infotype triggers retro. 2) Retro is also field dependent in an infotype.
    This is configured using view V_T582A under frame "Retro Accounting Trigger".
    Also note,
    1) Control record - PA03 contains earliest retro date, meaning retro cannot be run previous to that date for all employees in that payroll area.
    2) Infotype 0003 contains a field "earliest master data change" meaning during next payroll run retro will run from that particular period onwards for that employee.
    3) Infotype 0003 contains a field "Earl.pers. RA date" meaning retro cannot run beyond that date for that employee. (this field values are stored in table PA0003)

    Hello sir Every time I do the process of registration in Mogah Apple Store and the period and the period of the account is lost I do not know what the problem is there are people who enter into my account and change email We ask God to help you have an account I can not restore it the way I do not know where and I do not speak English Aalit Aalit help me I'm in a state of panic for your reply eagerly awaited
    This old Emily Hope you reply and help me [email protected]

    For what it's worth, you posted this in 2011, and here in 2014 I am still having this same issue. Over the last two days, I have had to unlock my apple account 8 times. I didn't get any new devices. I haven't initiated a password reset. I didn't forget my password. I set up two factor authentication and have been able to do the unlocking with the key and using a code sent to one of my devices. 
    That all works.
    It's this having to unlock my account every time I go to use any of my devices. And I have many: iMac, iPad, iPad2, iPad mini, iPhone 5s, iPod touch (daughter), and my old iPhone 4 being used as an ipod touch now.  They are all synced, and all was working just fine.
    I have initiated an incident with Apple (again) but I know they are just going to suggest I change my Apple ID. It's a simple one, and one that I am sure others think is theirs. I don't want to change it. I shouldn't have to. Apple should be able to tell me who is trying to use it, or at least from where.
    Thanks for listening,

  • Review period and Selection period in Enterprise Compensation Management

    Dear all,
    Anybody can explain about review period and selection period???
    Theory says u2026
    Review period
    The period when manager can plan and submit recommendations through MSS
    Selection period
    The period which system retrieves the set of objects (Org units, positions and employees) for compensation on portal.
    But I am bit confused with thisu2026 when this review will happen? In the beginning?
    Say example
    If itu2019s a merit increment and 01.01.2011-31.12.2011 is the valuation periodu2026 and we will give the increment in effective 01.01.2012 .Then when it be will the review period  and when it will be the selection period?
    Anybody can explain with examples plsu2026.
    Thanks and Regards
    Richard

    Hi Richard,
    You supplied the correct definitions, but your explanation is not correct. 
    The Review Period is that period of time the manager can access the system to enter the recommendation for a pay change.  In your example it might be 12/15 to 12/31.  Only during this period will the review be available for entry.  The 1/1 effective date is set in the Item attributes. 
    The Selection Period indicates for which employees the manager can make recommendations.  For example, if a person is transferred on December 20th in the above scenario - you would want the first manager to still create the recommendation and the individual not to appear for the new manager.  Thus, you would put 12/15 as the beginning and ending date for the Selection period.  Each manager would then see his/her direct reports as of that date in the recommendation area.  If you put 1/1/ to 12/31 in this field, any manager of the individual during the year could see and make entries in the recommendation area for the employee.
    Hope these examples help.

  • Consolidating with fiscal periods and calendar periods

    Hi, Does anyone have any information out there on how to configure the system to pull data for fiscal period for some companies and calendar period for other companies?  Or any horror stories about trying to do it that way.
    Thanks.

    Stacy,
    For consolidation as a whole only one fiscal year variant is allowed. However, there is possibility of collecting data of different fiscal year variant and using appropriate currency translation rates as per that units fiscal year variant.
    For example, if you have consolidation fiscal year variant as 31st March ending and you have one unit X as fiscal year variant 31st december ending, in this case the 12th period data of consolidation unit X will be translated using exchange rate as on 31st dec and not as on 31st March.
    Hope this might be helpful to you...though no direct response to your question.

  • Fiscal year and posting period

    Hai friends,
    I have a requirement like this,
    when I choose say 02/2008(posting period/fiscal year or posting period and fiscal year) in the Variable.  I also get data for the last twelve months….so my report would have
    02/2008,01/2008 ,12/2007…………………………………….03/2007.
    This variable should default to current posting period/fiscal year. So when somebody logs in he sees the current month and last twelve months.He can then change it to whatever he wants.
    The way I see it is that I have to write a customer exit and create a variable in which in “to” we will have current fiscal year/period and in “from” will have “Current fiscal year/period-12”.
    How to do this.
    Any help will be rewarded.
    Thanks in advance.

    Hi,
    Your approach is right.
    If you want the values to default and allow the users to change it, you should put the code under STEP I.
    WHEN 'variable'.
    IF I_STEP = 1.
    REFRESH e_t_range.
    CLEAR l_s_range.
    l_s_range-sign = 'I'.
    l_s_range-opt = 'BT'.
    l_s_range-low =  'Current Value - 11 periods'
    l_s_range-high = 'Current Value'
    APPEND l_s_range TO e_t_range.

  • COPA Report current period and previous period issue

    Hi Gurus,
    I have defined COPA report (Tcode KE94) based on line items. Now I want all values to be displayed based on an entry parameter in terms of period. That is to say that  If I give input values of "010.2013" as a period entry , my report should display the values for the the period specified i.e. 010.2013 in the first column and in second column  values for the period 009.2013 should be displayed and in the third column values for the period 001.2013 till 010.2013 should be displayed cumulatively.
    For this, I choosed the character "period/year" in General data selection tab, clicked "Variable on/off" tab and gave values "From"  as well as "To" for the Global Variable "OFP"  which is Curr.fisc.per./year.
    For the 1st column (1st column which is suppose to display the values according to selection parameter), along with the character "company code" , I choosed the character "period" and clicked "Variable on/off" tab and gave value "From"  as well as "To" for the Global Variable "OFP"  which is Curr.fisc.per./year.
    For the 2nd column (2nd column which is suppose to display the values for the immediately preceeding period of the selection parameter), along with the character "company code" , I choosed the character "period" and clicked "Variable on/off" tab and gave value "From"  as well as "To" for the Global Variable "OFP"  which is Curr.fisc.per./year. While doing so, I selected operator as "-" and choosed offset as 1.
    For the 3rd column (3rd column which is suppose to display the cumulative values from the beginning of the fiscal year till the period mentioned in the selection parameter), along with the character "company code" , I choosed the character "period" and selected 001 in "From" and 016 in "To" tab.
    Company Code selected in all the three columns is same and I have selected actual values i.e. 0 for "plan/actual indicator" tab.
    When I run the report through Tcode KE30 , I give values as "010.2013" for the From and To selection tabs. System shows the values as per the selection parameter in the 1st column which is correct  but display values same as per coulmn 1st in the 3rd column which is wrong because it should be cumulative. 2nd column is blank. 
    How to display the values for the immediately preceeding period and for cumulative period?
    Regards,
    makrand

    Dear Ajay,
    Thanks for the reply. Here are the screen shots.
    For the general data selection tab
    For the first column "current month" i.e. for the month
    For the second column "Last Months"
    For the third column "Cumulative" i.e. year to date
    Following is the result of KE30
    Values for the period 010.2013
    You can see that values in the report for the period 011.2013 contains value for the previous period which is 59090.21
    This value is matching when the report is run for the period 010.2013.
    But in both the reports,the figures for Current month and YTD (year to date) are same.
    Please let me know what setting is required in the current month column.

  • Budgeting and Planning periods in Comensation Management

    Hi guys,
    Do budgeting periods and Planning periods have to be the same in compensation management? Based on the SAP documentation, I understand that planning period can be different from budgeting period? What if my client has budget period from 01/01/2009 to 12/31/2009 and his planning period from 04/01/2009 to 03/31/2009? It should not matter to me since we are assigning the budgets to the adustment types. What are your views on this? Can you please let me know @ the earliest?
    Thanks in advance
    Sri

    HI,
    You can have different budget period and planning periods...it depends upon how the client wants it but you need to check how the amount assigned to an employee is deducted and from which budget period..
    eg. budget periods
    01.01.2008 31.12.2008
    01.01.2009 31.12.2009
    Planning period 01.04.2008 31.03.2009
    Planning period is overlapping 2 budgets hence will the amount for april to december be deducted from first budget and for the remaining 3 months from the second budget period.

    Hi Vamsi,
    Thanks for your response and our company metalink account has been expired, and Oracle no longer support us.
    I want to confirm that, do you mean that I update the adjustment month on gl_period_status, then the system can generate the 'missing' inventory accounting period and purchasing period, and also other periods that should be existed?
    Thanks for kindly help!

  • How to add FISCAL YEAR, Period and Day to cube.

    hi,
    I am using SD EXTRACTORS (2LIS_11_VAITM, 2LIS_11_VAKON, 2LIS_12_VCITM and 2LIS_13_VDITM) and directly updating each corresponding ODS and cube.
    All the extractors only have FISCAL VARIANT has the time characteristic. So, all my ODS contains only one time char - fiscal variant and other dates (liek document created date etc. (not a time char)).
    Now, I want to use fiscal period, fiscal year and fiscal day in my cube. I have added these time char in my cube.
    My question:
    1. how to get FISCAL YEAR, FISCAL PERIOD and FISCAL DAY get updated. Do I need to map to document created date in update rules or Do I need to use some functional module.
    Pls note I am bringing only FISCAL VARIANT from R/3 into ODS and then to CUBE.
    PLS REPLY.

    thanks sundar..i got your point..but I have one question
    All the cubes (sales, sales condition and billing) have the sales order number (VBUK-VBELN) and item number (POSNR-VBUK). But info objects used for these fields in sales cube and sales condition cube are same but for billing it is not same.
    Can I combine all cubes (sales order, sales condition, billing) in muliti provider.
    1. Sales order cube (from VAITM)
               Sales order number (VBUK-VBELN) --  (0DOC_NUMBER)
               Sales Item (VBUK-POSNR)              --  (0S_ORD_ITEM)

  • Return current period based off of current fiscal year and date

    Good Afternoon,
    Is there a way in the webi that I can create a dimension that always reflects the current Fiscal Month based of Fiscal year and date? I have a report that I am trying to show sales for a customer based off the current fiscal month. I would like this report when refreshed to be based off this fiscal month dimension instead of showing each fiscal month or changing it manually. What is the best way to do this?
    I have attached an image that shows current numbers by period (month) and then the YTD Totals. I would like to have my 'Period' column always reflect the current period and the Total column to reflect that months totals based off the period column. So for this period (3), instead of seeing 3 lines for each month I would just see the '3' and the total as $541,310.46, monthly as 412,502.09 and my YTD as 1,080,091.06.
    Any help is always appreciated!
    Thank you,
    Tiffany

    Hi,
    Create a variable
    FlagVar=If([Period]=Max([Period]) In Report;"Show";"Hide")
    And apply block filter of FlagVar=Show
    Are these coming TotalSales  MonthlyGoal YTDSales directly from universe? If they are calculated at report level then you might want to use NoFilter. like =NoFilter([YTDSales])

  • Using fiscal period and Fiscal quarter reporting seemlessly in a BI Query

    Hi,
    We have a very specific issue. Reporting the Fiscal Period( in our
    case we have 53 fiscal periods) and Fiscal Quarter( we have 4 quarters)
    in the same query seamlessly as we would have done using Calander Month
    and Calander quarter in other reports that uses SAP delivered standard
    time dimensions.
    However unlike the Calander time dimension (SAP provided all
    possible...0CALDAY, 0CALWEEK, 0CALMONTH, 0CALQUARTER, 0CALYEAR) where you have all of these inside your info provider, you can get
    aggregation on week, month, quarter etc in your query seamlessly, The Fiscal Year/Period offers a problem in doing report seamlessly.
    When we delve into Fiscal realm, SAP only provided with 0FISCVARNT,
    0FISCPER, 0FISCYEAR and a special period 0FISCPER3. It doesn't provide
    anything like 0FISCQUARTER etc and rightly so, because you can have
    only one 0FISCVARNT in the Time dimension and can have related periods
    (0FISCPER) only for a Row of data in your infocube. For example if you need to model as per the Fiscalweek, you can create a custom Fiscal year variant (Say z1) and can configure to have only 53 periods (Mapped to 0FISCPER) representing
    53 Fiscal WEEK. Similarly for mapping Fiscal Quarter you can create
    another fiscal year variant (Say Z2) and have only 4 periods (mapped to
    0FISCPER also in this case) to represent the 4 Fiscal Quarter. However
    the issue is that for one record you can only map either of those and
    not both since you can only have one Fiscal year variant in one row of
    data in the info provider.
    For example
    If I have two rows OF DATA coming from different sources (One FOR
    Fiscal Week and another for Fiscal Quarter) I can have the following in
    my info provider.
    1> Example data in Fiscal
    Char1 Char2 0CALDAY 0FISCVARNT 0FISCPER Quantity
    X  ......  y .....10/22/07 ....Z1 ....           43’2007 .......10
    X .......  Y .....10/22/07 ....Z2 ....          Q3’2007 .......20
    The issue is how do I report the Quantity in a query in Quarter Q3 as
    (10 + 20 = 30) since both the rows corresponds to FISCAL Q3’2007?
    (Please note that Fiscal week 43’2007(For VARIANT Z1 ) actually is
    Fiscal Quarter Q3’2007( For Fiscal Variant Z2) as per our
    configuration of Fiscal Year Variant configuration Z1 and Z2)
    The same is very simple when I have infoprovider with CALENDAR Time
    dimensions , for example if we don’t have any fiscal reporting
    requirement and just report on calendar time dimension the record in
    the info provider would look like the following ( example)
    2> Example Data in CALENDAR DIMENSION
    Char1 Char2 0CALDAY 0CALWEEK 0CALQUARTER Quantity
    X ........ y .......10/22/07 .......43’2007 .......Q3’2007 .......10
    X ........Y .......10/22/07 ....... 44’2007 .......Q3’2007 .......20
    Here we can use both 0CALQUARTER and get the data aggregated on the
    quarter level in addition to the 0CALWEEK.
    To solve this issue, One option that we are thinking of Using 0CALQUARTER to represent the
    Fiscal Quarter and use Update rule to populate this one. For example
    THE example 1 can be as follows.
    1A> Example of using 0CALQUARTER along with 0FISCVARNT and 0FISCPER
    Char1 Char2 0CALDAY 0FISCVARNT 0FISCPER 0CALQUARTERE Quantity
    X .......y .......10/22/07 ..............Z1 .......43’2007 .......Q3’2007 ..............10
    X .......Y .......10/22/07 ..............Z2 .......Q3’2007 .......Q3’2007 ..............20
    In this case we would populate the 0CALQUARTER by the actual Fiscal
    Quarter and then can use both as per example 2 above. But this is not a
    smooth option since we have various other info providers to join and
    report based on solely Fiscal Quarter etc…
    I am certain that this issue have already been solved by somebody as this bound to happen in any finance application.
    Would appreciate if we can get some light on this regarding the data modelling, reporting etc.
    Thanks
    Arun G.

    You have yourself suggested a solution, which is fine,
    Other option is to have a new characteristic Fiscal Qtr in all the infoproviders ans update the same using a routine in the updaterule depending on the fiscal year variant.
    for eg. for transaction with variant Z1 in one case you can say if fiscal week 01 between 01 to 13 the Fiscal Qtr should be update with1 and if it is between 14 to 26 then update fiscal qtr with 2 and so on.
    For other Variants Z2 you write a different login in the routine ans so on.
    so for all the data irrespective of the variant you will have the qtr as either 1 or 2 or 3 or 4 and you can report on this fiscal qtr.
    assign points if it helps.
