MM02 forecast periods

Hi,
in mm02 in forcasting tab the forecasting periods where it will store that value,
or else how to get that value for perticular material,
THX

Hi,
1. History periods:
The number of historical values the system uses for the forecast.
If fewer historical values exist in the system than specified here, the system includes all the existing values in the forecast.
If this field remains empty, no historical values are used to carry out the forecast. However, this is only possible in the case of manual initialization.
2. forecast periods:
Number of period splits for which a forecast should be created.
3. Periods per season:
Number of periods that belong to a season.
Procedure
You only specify a number
if the forecast model is a seasonal model
if you want the system to carry out a seasonal test
4. Initialisation periods:
Number of historical values that you want to be used for initialization.
If fewer historical values exist in the system than specified here, the system includes all the existing ones.
If the field remains empty, no historical values are used to initialize the forecast.
5. Fixed periods:
Number of periods for which the system will not recalculate the forecast values in the next forecast. The fixed periods start with the initial forecast period.
Use
You enter a value
in order to avoid excessive fluctuations in the forecast calculation or
because production can no longer react to changed planning figures in the specified horizon.
Hope this helps.
Award points if useful.

How to copy actual data into current forecast period

Hi gurus.
I need your guidance on how to copy actual data into current forecast period.
This is my case. Let's say I have the following figures for my actuals:
January 2007 Actual = $110,000.
February 2007 Actual = $120,000.
March 2007 Actual = $80,000.
April 2007 Actual = $100,000.
Now, my user want to choose any month as the basis for her forecast for the remaining periods. Let's say, she wanted to choose April 2007 Actual as the basis for the remaining forecast periods, so I should be able to display the following figures in my planning folder:
May 2007 Forecast = $100,000.
June 2007 Forecast = $100,000.
July 2007 Forecast = $100,000.
August 2007 Forecast = $100,000.
September 2007 Forecast = $100,000.
October 2007 Forecast = $100,000.
November 2007 Forecast = $100,000.
December 2007 Forecast = $100,000.
Can someone guide me on how to do that?
Points will be given to good and best answers.
Thanks.

Hi Fulham,
Technical answer:
First, you need to allow your user to indicate wich month is the reference for the copy. I suggest you to add a new key figure in your actual layout (a 'customizing' layout) that your user will use as a flag:
January 2007 Actual = $110,000
January 2007 Flag = 0
February 2007 Actual = $120,000
February 2007 Flag = 0
March 2007 Actual = $80,000
March 2007 Flag = 0
April 2007 Actual = $100,000
April 2007 <b>Flag = 1</b>
<i>(Help to a fox or an abap exit you can check that only one month is 'flagged')</i>
Then, in the corresponding level for the data input, you use a function exit in Abap, which will:
- read the previous customizing layout help to API_SEMBPS_GETDATA so you can get the flagged month and its actual amount ($100,000)
- generate the news rows into the table XTH_DATA which will be automatically posted in the level with the actual amount
Is that clear?

Requesting detailed config and setup for forecast 'period splitting'

I have searched the SAP community, and found little detailed information about configuration and setup for SAP forecast 'period splitting'.
I have selected the standard scenario in the 'Splitting Indicator' (1 - 2 - 4) in MM03/MRP3 for splitting month periods into weeks - AND - I have set the MRP Type found in MM03/MRP1 to 'VV' as specified (with "obligatory forecast indicator set on, which supports forecasts to be used as a basis for MRP).
Doing so has not resulted in my monthly inputted forecasts being split into weeks.
I am thinking that there is some missing configuration that is needed. Please advise if you can.
Thank you

Bert,
Now I am more curious than ever. You mention that your forecasts are not generated by SAP, but are generated by an external forecasting program, using requirements type VSF.
This sounds like your interface program is entering Planned Independent Requirements, not forecasts (for VV MRP type, the MRP element for forecast requirements is called "FORERQ" and not "IndReq"). The field to which you refer ("Splitting indicator" in the MRP3 tab) has no impact on Planned Independent Requirements. To my knowledge, it only works with the integrated forecast generation program that is commonly used in VV MRP type.

Automatic reorder point planning -forecast view

Hi
Our client want to implement automatic reorder point Planning.
Reorder point quantity was maitained from last 3 years but MRP type is 'ND' as they are not using MRP.
Now i am changing MRP type to:VM and in forecastting view: i maintained model as:D constant model period indicator:M
His periods:60 , forecast periods:12 initialization:X tracking limit:4000 selection procedure:2 reset automatically
Is it ok ? than can i run MP30. and the client wants to run for many materils(2000).
How can be run for many materials.?
Regards,
srihari.M

Dear,
In automatic re-order oint planning , system uses past consumption data (historical data) to forecast future requirements. The system then uses these forecast values to calculate the reorder level and the safety stock level, taking the service level, which is specified in MRP2 view, and the material's replenishment lead time into account, and transfers them to the material master.
Since the forecast is carried out at regular intervals, the reorder level and the safety stock level are continually adapted to the current consumption and delivery situation. This means that a contribution is made towards keeping stock levels low.
From MP30 you have to executed forecast and system has generated forecast values and updated safety stock and reorder point also. Only thing to remember is you have to maintain service level in MRP 2 view of material master when you use VM- MRP type to calculate safety stock and reorder point
Find bleow the set up following set up for automatic re-order point planning :
1.Material Master Set up : Maintain all the relevent parameters from MRP1 to MRP4 view , Forecasting View
1.MRP Type -VM , Lot Size -EX
2.Procurement Type -E for FG and F for ROH
3.Planning Startegy -10 or 40 in FG/SFG and 20 for componenet
4.Planned Delivery Time in MRP2 VIEW
5.Indiviaul/Collective Indicator - 1/2 based on your requirement in MRP4 View
6.BOM Explosion -Keep it blank
7.Service level percentage -MRP2 view
8.Maintain Forecastin view data like model selection , Histry period , period indicator , Forecast control pramaters ,
10.Make sure that you have min 12-8 monhts total consumption update in Forecasting view .
Configuration : InSPRO -MRP -Check MRP Type -VM-check the details like Re-Orde point .Safety Stock both the automatic calcvualtion box are marked .
Finally as a sample test , select any material -mm02-execute forecast in mm02-forecasting view -exectute forecast -then save .Run MRP in MD03-1,1,3,3,1.NETCH indicator and check the result in MD04
HOPE IT WILL HELP. PLEASE REVERT BACK.

Reg doing forecast planning for first time

Dear all,
I need to run forecast based planning for the first time, I only have past consumption values and I want to use constant model
How to run forecast moreover my alpha value is 0.1 and consumption values for past 10 months are 100,120,100,140,160,120,100,200,120,140, what would be my forcast value If I run for constant model and how system calculates that value
regards
venkat

Dear ,
Please follwo the below steps for running forecast for Constant Model :
In MM02 you should maintain the following paramters :
1.MRP1-MRP4 view : MRP Type -VV, Planned delivery Time , Lot Size-EX , Servicelevel Percentage -80-90% , Plannnig Startegey -10/20 as applicable , Procurement Type -F/E/X as apalicable , Period Indicator-M etc .
2.In forcasting view , Please maintain the following :
1.Forecast Model -D (Constant Model) 2.Period Indicator-M (flolows from MRP views) , Histry Period-10 ,Forecast Period -2/3 (How many months u want the system to forecast ) ,Period per sesson -10
In Control Data : Initialisation -X , Model Selection -A , Traking Limit -4 , Reset Automatically -Marked ,Optimisation Level -F
Now , if you enter the smoothing factor : Alpha , beta , Gama and Delta each 0.30 , hit enter , it will re-set Appha 0.1-0.05 and Delta 0.30 because this two is applicable for Cosntant Model
Finally save this and execute Forecasting through single material in MM02-Forecasting View -Exectute Forecast Option or Collectively total forcast thropugh MP38 .Result will be Foercast Qty , basic Values , MAD , Safet stock .
Look around your detail formula which have used in Forecasting calcualtion based on the model selection in the below link :

Automatically creating PIRs by reference material forecast

Hello All,
I want to ask you about automatically created Planned Independent Requirement. I have a material number (A).
When I do "execute forecast" in MM02 for material A, the forecast values are created.
Then I run MRP from MD02 for material A.
When I looked at MD04, I saw the planned independent requirement quantites are the same as forecast values. How could it be? Can the system automatically created PIRs by reference material forecast?
For doing this, which field is need to fill in MM02?
Thank you for your support...

Hi,
can you please say which type of mrp you are using?
It is possible to use information from the sales forecast, the Sales Information System, or
other planning tools to plan production quantities.
You can use the material forecast to determine planned independent requirement quantities. You
must maintain the following data in the forecast screens in the material master record:
Number of the required forecast values
Forecast periodicity
Thanks

Set Period Indicator for MVER

Where in the IMG or std system do you set the Period Indicator for the consumption posting table MVER?
Currently all movements are posting as Month. I need to change this to Period.

I believe t-codes MM02 Forecasting and MM17 would be used to change the Forecasting period indicator in table MPOP, not the Consumption Usage period indicator in table MVER.
As soon as you perform a real time consumption movement such as peforming MB1A with movement type (GI Cost Center), the total and unplanned consumption are increamented by the transaction quantity immediately in table MVER. The results can be seen in the Material Master MM03 view (Additional Data/Consumption). When it updates the table is considers the period, which mine is currently M (Month). There should be some place I can change this to P (Period).
Thanks for your input

MRP Type VV - Forecast Based Planning

Hi all,
My company would like to look at MRP Type "VV" - Forecast Based Planning (under Consumption-based Planning) for FG production materials.    I've read quite a bit about the concept and some based set up to how it works.   We would like to base Planned Orders > Production Orders based on this type of forecast planning.   It seem that SAP advises this kind of plannig for Raw Materials but not FG.   Anyway, what I really need to know are the specifics of how you set up the master data (in the Material Master) to properly execute this type of MRP: like....
MRP Type: VV
Lot Size: EX
Period Ind: W
Availability Check: 02
Forecast Period:   12
Periods per Season: 12
Historical periods: 60
other fields I'm not sure......
RP Profile: ??
Forecat Profile: ??
what else......?
Also, what is the recommended approach to convert this forecast plan into Planned requirements to be converted to Production Orders?
I appreciate any further information I can get on MRP Type "VV" and how it works.   I appreciate your input!

Thanks for the info nudratmaab.    Can you provide further data on what to expect given this forecast.....say I pick MVGA (Moving Average Forecast)? So I enter some consumption (say last 12 months) and run forecast (MP38).    The MD04 shows the average requirement per "W" bucket:
02/23/2012     ForReq     W 08/2012                16-
02/27/2012     ForReq     W 09/2012               116-
03/05/2012     ForReq     W 10/2012               116-
03/12/2012     ForReq     W 11/2012               116-
03/19/2012     ForReq     W 12/2012               116-
03/26/2012     ForReq     W 13/2012               116-
04/02/2012     ForReq     W 14/2012               116-
04/09/2012     ForReq     W 15/2012               116-
04/16/2012     ForReq     W 16/2012               116-
04/23/2012     ForReq     W 17/2012               116-
04/30/2012     ForReq     W 18/2012               116-
05/07/2012     ForReq     W 19/2012               116-
The next part is where it is a little foggy for me.   For "VV" do I run WRP1 (Replenishment) or do I run MD02/ 03 (MRP) and then what is the ForReq converted to (or does it even convert)?   I'm looking to implement this for Production Planning Requirements for Finished Produced products (I need them to convert to PldOrd (Planned Orders) to be converted to PrdOrd (Production Orders) by production scheduler.
The second part of this is the Raw Material (BOM component) associated with these Finished Goods. THese BOM components are set up as MRP Type "PD" and Lot size "EX" and I was hoping that the FG MRP run would also do BOM explosion and drive requirements for the Raw Material as well.....I'm not seeing that.
I need professional / expert to tell me how this works:    So MRP Type "VV" & Lot Size "EX" for the Finished Goods.......and MRP TYpe "PD" & Lot Size "EX" for the Raw Material (BOM Component).....
THanks again!!

Forecast function in integrated planning

In forecast function of integrated planning we need to fix forecast period time interval in tcode(RSRHIERARCHYVIRT). otherwise it will show error like
"Forecast period doesnot fall with in F4 time interval" if we fix that in respective tcode mentioned above. then it will error free.
But my doubt is we need to fix past period time interval also in the same tcode. because we need both forecast period and past period in forecast fucntion.
How we can fix both at a time, i need to fix error urgent. pls help me
I will assign very good points

Forecast based planning -weekly schedules split -reg

Hi,
our requirement is we use forecast based planning where in both forecast periods and historical periods are months
then when fore cast is run requirement is coming in Md04 in monthly buckets only
when we run MRP the out put schedules should come in weekly bucket taking this monthly requirement
how to get that
as we understand weekly demand can be cumulated to get schedules on monthly but monthly demand can not be split in to weekly schedules as output
any thoughts
regards,
Madhu

Hi,
There's a customization transaction where you can define splitting of forecast requirements for MRP.

Finished material forecast

Hi Gurus,
Can anybody please clarify my confusion. Our business wants to forecast to the finished material, saying how many will need to be produced in a given time frame. based on this the system will kick the reuqirements down to the level of raw material. Now in MM02 on the forecasting view there is foreacast values button, do we maintain here the forecast values of the finished material that we anticipate to build, Or is it in MD61 - planning table where we maintain the sales forecast. The whole objective of the sales forecast is to make the purchasing dept ready with teh materials that are procured externally to be able to meet the forecast of the finished material. Please help
Thanks
Anusha

Hi Anusha,
It will be better to use MD61 rather than MM02 & Forecast button.
In both cases you can plan Raw Materials using the BOM and the MRP (PP)
If you want to populate the values Manually the MD61 is the transacction
If you want the system to Forecast the values use MM02 + Forecasting.
If you use MD61 that will generate the Planned Independant Requirements (PIR) that will generate the "Issue" of the Finished Goods. You will have to associate the Strategy Group (If you do not know about this start with strategy 40) in MRP 4 view.
Once you have your PIR available for the material MD04 you can run the MRP. Depending on the strategy and some other factors the PIR will disappear as soon as you start createing sales orders for the material.
Kind regards,
Federico

Problem with Period selection in PPOME transaction!

Dear All,
I have a very strange problem while selecting the time period in the PPOME transaction.
While selecting the "date and forecast period" option from the "settings" option in the menu bar, the time period in the preview the PPOME transaction must show as 3 months by default. But for my user ID when i select the preview period, the month field is displayed as blank and the end date is always defaulted to current date.
Is this time period coming from any configuration? I would like to know is there any way to by which we can change and save the time period settings.
Thanks,
sridharan

Goto PE03->ABKRS in Change mode. You will be able to uncheck or check the fields.
