Reg Forecasting

Hi
I am new to DP.
please anybody clarify these doubts...
What is univariate forecast profile? and what is multi leaner regression?
What are the differences between UNIVARIATE & MULTILENIAR?
What is forecast accuracy?
How do you find out, which is fit to forecast?
please explain.
i am very much thankful to you
Regards
Anitha

Hi Anithaa,

For MLR refer the following link:
http://help.sap.com/saphelp_apo/helpdata/en/ac/216ba4337b11d398290000e8a49608/frameset.htm
Which is the best model to use:
You should try running forecasting using various model(seasonal, seasonal linear, linear, constant etc) and comapre
the forecast accuracy and find out which one is the best suitable.
Another way is to choose auto model which will select the best possible forecast strategy and give the result.

Reg Forecast functions in Oracle

Hello Everybody,
Is there a forecast function in oracle that's equivelent to forecast function in MS Excel ?

Not sure about MS Excel, but Oracle has MODEL clause that can be used for projections.
Take a look into
"Example 2 Sales projection that fills in missing data"
at http://docs.oracle.com/cd/B19306_01/server.102/b14223/advbi.htm
Also I know that projections can be done in Oracle OLAP Option using OLAP DML.

Change over from reorder planning to forecast -reg

Hi,
Currently we are using for some parts manual reorder point planning wth MRP type V1 and strategy 40
We require to change to forecast based planning where in we can change MRP type to VV and what strategy we have to put
any specific for forecast based planning
we use make to stock scenario only
as of now the requirements are calculated based on the customer orders and reorder point as per the current settings
we need the requirements calculation with past consumption values only then is it required to change the strategy to 10 from 40 ?

I do not think so.

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.
Go SPRO, Materials management, Consumption based planning, Forecast, Define Splitting of Forecast Requirements for MRP.

Forecast History reg

Hi Team
My forecast history loaded incorrectly, please let me know what could go wrong.
Thanks
Raj

Dude....
Is that all?
Your forecast history came from where? How did you try to load the history?
Why did you try to load the history? As far as I know, loading forecast history was never recommended. That may have changed, but I believe there is an Open Interface with which you can load.
Go back and check your API mapping and let us know.
Good luck,
RD

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 :

Forecasting Error messages : CBP with auto model selection

Hi
I need to understand forecasting errors. Im working on consumption based planning with MRP type 'V2', when i execute the forecast i get error messages as"timeseries characteristics changed", "parameter optimization accesssed", "expost forecast carried out" etc. I checked in the customization where the errors are assigned to error classes(class 1 to 8). Can someone tell me how to interpret these errors, if possible any documentation reg this errors would be useful. "[email protected]"

Hi
My requirement is to calculate reorder point and safety stock via past consumption, so thats why im using MRP type V2. Pls correct me if this mrp type is wrong for calculating safety stock and reorder point based on past consumption or to use any other mrp type. any documentation on forecast error messages would be really great with points assured."[email protected]"

Forecasting in SOP

hi
I want to know about the calculation in forecasting in SOP
Mean absolute deviation, Ex post Forecast,Basic value , alpha beta factor
How these values r calculated?
Amit

1.SAP - has forecast profile.
inside the forecast profile we have the forecast model
Each mode has it own calcualation..All the belwo mentioned values are used for calcluation in arrriving at the forecasted value at the end of the forecast run
2. i have explained little on the few elements
Basic value:It is used in arrving the first order exponential smoothign value.
These below 2 values help you to calculate the forecast:
alpha :The system uses the alpha factor to smooth the basic value
beta:The system uses the beta factor to smooth the trend value
How these values r calculated?
The below link should help and answer all your questions.

About selecting Scheduling Agreement and Forecast delivery schedule

Hi Experts,
i want to write a Report, with 2 parameters for the selection : Sold-to-party and Period
For this Sold-to-party/Period, I want to list all scheduling agreement + Forecast delivery schedule.
I already found the Function SD_VBEP_READ_WITH_VBELN to read all Forecast delivery schedule lines using Sales Doc.No. , but how can I select all Scheduling Agreement for the Period ?
Regards,
David

Solution:
by selecting data from table VEPVG (Delivery Due Index) and using function SD_VBEP_READ_WITH_VBELN for each SD Document.

David

Can Demantra Forecast at a National level?

Good afternoon Forum,
I posted a thread about a month ago and am back again to hear some more good advice and information. I work in a business group which supplies spare parts nationally through regional distribution centers for a large industrial equipment installed base. Despite me being against this, our management has decided to use Demantra to forecast parts usage at the National level and then force down to the regional distribution centers to take a percentage of parts based on past percentage of the total, rather than roll up the individual regional forecasts to create a total.
My question is can Demantra be set to do this? What would it take? Besides being less accurate at a regional level, what other drawbacks are there?
Thanks in advance for any assistance you can provide.
Best regards,
ABoyNamedJoe

Hi Maggie,
To solve the proble, I think the best way is to create something like dummy entity, which is usually called adjustment entity as Alwin mentions.
Please remember not making any child entity of the adjustment entity. Otherwise, the adjustment entity won't be base-level member anymore, and you can not post data.
Hope it helps.

Creation of forecast delivery in Sceduling agreement

Hi experts,
I would like to know if it is possible to create a forecast delivery line in scheduling agreement using IDOCs. The scheduling agreement is already existing but it has no forecast delivery line. If it is possible, kindly give me the basic type, message type and the fields to be populated with what data.
Thanks in advance,
Lalyn

The actual scenarois is this:
I am getting AUFNR(prodcutoin order),LGNUM(whs number) ....etc from XI system. I hav to use this data and have to create an Inbound delivery from expected GR in EWM and POST GR in EWM and Creation of Whs task in EWM again.
The transaction to create the inbound delivery from expected GR is /SCWM/GRPI (GR Preparation: From Production).
we do not have any BAPI or FM in EWM to acheive this. Pleas help me in resolving the issue.

Can't See Historical Forecast in SPP

Hi
We have loaded the sales order data using a flat file.We were able to load the data into the cube 9ADEMAND (but not into the ODS 9ARAWDAT).
We are also able to see the demand data in the forecasting planning book and even forecast is also getting generated.
The problems which we are facing are
1. Standard Deviation of Demand, MAD etc are all 0.
2. Not able to see Historical Forecast ( tcode /SAPAPO/SPPFCSTTARK) . The error message says " No historical forecast time series can be determined".
Can anybody tell us what could be the problem ?
Thanks in Advance
Mitesh

We are having a similar issue, could you provide the configuration done to the planning profile for recalculation of historical forecast?

Mail can't send email from 123-reg accounts

Hi all,
I've got an issue with Mac Mail can’t send email from 123-reg accounts.
I know there is a lot of articles on simular matters and some I have tried out with no luck, others are just speaking a whole other language.
Any help would be greatly recived, here's my situation below:
Running a iMac 2.8GHz Intel Core i5 on OS X 10.8.3
I’m using 3 accounts on Macs Mail client, one is my iCloud account that is working fine and the other two are my 123-reg accounts that I use for business purposes. I’ve been working like this for a couple of years now and about 6 months ago I upgrade my operating system from Snow Leopard to Mountain Lion.
2 or 3 months ago I randomly got a problem where I was unable to send any emails from my 123-reg account, I could only receive emails. I checked my settings and they were all correct and unchanged so I attempted to delete them and recreate the account but with no such luck.
I then decided to check if it was a problem at 123-regs end and attempted to log into web mail. This worked and was able to both send and receive emails so eliminated that possibility.
I also have these accounts set up on my iPhone, so checked if there was any issues and everything was working fine. I then checked my iphone details and made sure the same was on my desktop and still no such luck.
I’ve tried out some of the articles I’ve found on here (the ones written in plain English) still no results. I’m not very IT illiterate and just wondered if anyone else has got any ideas, whether there is something specific with 123-reg accounts and Mac Mail?
Many thanks.

Thanks
I just had another hunt around looking at posts and discovered that it was because I recently changed to BT Infinity and they had a block on.
I didn't even think to question the ISP.

Issue in consumption of forecast for configurable material

Hi,
we have a issue in consumption of forecast by sales order for a configurable material.
Please find the below details for the settings maintained and the steps followed.
Please let me know how we can overcome this issue.
settings in R/3
1. Class and characterisitcs are created in R/3
2. standard material was created and class assigned
3. planning strategy used is 56
4. material, class, characteristics,ATP check, ATP customizing , sales order were integrated to APO
Settings in APO
1. CBF table, CBF profile, Consumption group were created in APO
2. Consumption group is attached to the product master
following steps were followed.
1. Forecast was created in DP for a certain characterstics ansd relaesed to SNP/PPDS
2. forcast is visible in product view
3. sales order was created in R/3
4. slaes order is visible in APO but it is not consuming the foreacast for the same set of characteristics.
Please let me know how we can overcome this..are we missing any customization ...?
Thanks
Ram

Hi Srinivas,
thanks for your response.
The forecast consumption problem was solved after correcting the entries in requirement strategy.
have one more query.
when the sales order for a configurable material is transferred from R/3 to APO, we should be able to see the values under "descriptive characteristics tab" in APO product view.(when we click on the green triangle representing the configuration).
However, we could see the values under "descriptive characteristics tab" for some of the characterisitcs and not for other characteristics.
we tried comparing the characteristics but could not figure out the reason.
any pointers / clues to come over this issue would be helpful.
thanks
Ram
