Demand Planning - Forecast Profile .

Hi SAP GURUS,
Need to modify the Forecast Profile for to have different weightages for each month because of holidays and different working days.
Any solutions for modifications.
Thank you
Rahul Chitte

Hi Rahul :
There is a fetaure called "Workday adjustments" which you can use to account for varying no of workdays in a month .
System claculates statistical forecast baased on avergae no of days in a month . You speicfy this in average no of days in vnivariate forecfast profile . The no of workdays in any month is determined by factory calenadr in planning area . System adjusts the uncorrected forecast based on following formula
Corrected forecast = (uncorrected forecast/average no of days) * actual no of days .
So You should ahve an additional key fig for corrected forecast

Demand planning Forecast errors and KPI to store results of error

I have following requirement: keep traceabilitity of hypothesis and forecast error results of former mass process .
In comparison tool, we can compare the result of last interactive forecast run but our requirement is to store those result for KPI purpose.
Is it possible without extra development ? ( built not yet done, we are in design phase)
Kinds regards,
Christine

Hi Christine,
There is Standard Error analysis functionality available for forecast accuracy reporting.
Please refer to the URL below:
http://help.sap.com/saphelp_scm70/helpdata/en/6f/8812ce03ba4f0ca09ea31a1a3e1f0c/frameset.htm
Please check if these are sufficient for your business needs.
If we want to extarct standard statistical forecast errors( like MAD, MAPE) calculated in the interactive or batch runs of statistical forecasting , then, to my understanding, development is required. A short detail is given below:
We need to develop macros for calculation of Univariate forecast erros : MAD and MAPE. New planning book and data views may be required to becreated Some extra Key figures also will be needed ,used for storing the values.
The macros runs can be run through batch jobs.These calculated forecast errors of MAD and MAPE then can be compared with the system calculated MAD and MAPE during interactive / batch runs.
The error data can be extracted and stored in the infocubes.
Please check and confirm.

How to configure for the give senario where we from APO demand planning, we provide baseline forecast into TPM

Hello Guru's,
Request for information on smart documentation on the integration between Trade Promotion Management and SCM-Demand Planning from an architecture perspective how to configure for the give senario where we from APO demand planning, we provide baseline forecast into TPM and from TPM promotions values can be considered in to APO demand planning: can anybody give me some insight on it.
Thanks in advance.
Kumar

Hi Praveen
There are several ways you can connect a DP system to a TPM. How are your interfaces and systems setup?
Option1:
Extract the baseline from APO to a BW cube, extract the data out of BW, may be using infospokes/open hub and pass it on to TPM.
2. Have a custom program written in APO-DP to extract the selected keyfigure data at the aggregation level into an interface or a .txt file into APO directory and use some data transfer service such as EDI to take this data and send to TPM.
In my experience it is simple to define an integration process. The much larger and complicated aspects are the date adjustments and the aggregation levels.
Date adjustments:
Understand the basis of the data in APO and TPM. APO is usually at the requested delivery date or material availability date ( when the customer like a store wants the product). However TPMs are usually at the consumption date ( when an end customer like you and me but from store shelf). Depending on the product and business style this can mean several days difference. Let's say it is 25 days on average, you need to add 25 days to APO base line date to get the TPM consumption date.
Aggregation level:
This can be product or customer. If the planning in DP is at product sku level and the TPM is at packs or brand level, you need to aggregate the data up before loading to TPM. The same with customer.
To me the most complex part of the integration is to understand and transform the data in a meaningful way and a strategy to sustain this integration by keeping both DP and TPM in sync in terms of master data. Also important to have a process for identifying exceptions and failures. you send baseline from DP to TPM and if it fails, how do you know? how do you trouble shoot?
Hope these help.

Mixed periodicities in a forecast are not allowed In Demand Planning

Hi All,
I am running forecast in background by defining activity and job in transaction /sapapo/mc8t and /sapapo/mc8d .
I am scheduling the job in transaction in /sapapo/mc8g.
Before scheduling the job i checked the job in transaction /sapapo/mc8i and this check is fine.
When I am running the job in background i am getting the following error message:
"Mixed periodicities in a forecast are not allowed".
This error I am getting in the spool of job in SM37 transaction.
I ran a copy key figure macro in the same planning book with the same view and it is having no problem.
In my planning book i am having only one dataview and with that dataview only i am scheduling the job.
The strange thing is that the forecast is running smoothly in interactive mode in same planning book,same data view with same forecast profile.
Did anybody face the same problem in the past?
I am using SAP SCM 7.0 version.
Thanks In Advance,
Mukesh Pandey

Hi,
I contacted SAP on the same and they suggested me exactly what was the problem.
I will try to explain the problem with an example here as that would be easy.
Say, My storage bucket profile is a custom week.
suppose i am doing forecast at custom week level.
my time bucket profile in the planning book is "2 years in months".
So here in the background job we are expecting from the system to first divide years in months and than months to custom weeks. Here we are referring to mixed pereodicities.
So the rule is your time bucket profile and the bucket of forecasting should be directly in proportion of storage bucket profile.
it should not be
Year-->month--
>week
it should be
Year-->week or year>month or month--
>week.
I hope i am clear.

Mukesh Pandey

Demand Planning: How to create a forecast in ODP

Our client is using Oracle Financials OM etc however it currently uses a separate tool for forecasting. We are planning to start forecasting in Oracle Demand Planning.
Following is the simplified calculation for forecasting, how can this be done in ODP:
Calculation is done for item type, 2 calculations are done for every month (X and Y changes every month):
JAN:
1. A= X% of Jan sales
2. B= Y% of last year sales
The forecast should pick greatest number among A and B (it should not pick A+B).
Is this possible in ODP, how to setup the forecast and its calculations.
Thanks in advance.

You could do this in ODP using the absolute value function and some formula measures.
I assume you are familiar with formula measures in ODP and hence I will focus only on the math behind the formula measures. I am ignoring the percentage aspect that can be easily achieved using formula measure capabilities.
The result set that you want is the following:
if X > Y return X else Y
Formula measure 1 = FM1 = X + Y
Formula measure 2 = FM2 = = |X - Y| (absolute value)
Formula measure 3 = (FM1 + FM2) / 2
How does this work?
|X - Y|
returns Y - X if Y > X
returns X - Y if X > Y
if X > Y then the result is
(X + Y + X - Y)/2 = X
if X < Y, then the result is
(X + Y + Y - X)/2 = Y
This will give you the results you want.
Note: the formula measures apply at all levels of the hierarchy and is not the aggregation from the lowest levels.
Please be careful and validate this solution against your total set of requirements.

SAP ERP - Demand Planning and Forecasting

Dear all,
my customer is a wholesale company. They want to use a component in SAP ERP (not SAP APO), in order to make demanding planning and forecasting for the materials , quantities and dates they should make the purchases in order to cover the demand of their customers. What is the component that should be used in order to achieve this?

MRP can be used without production planning. SOP and Demand Management are not Production.
Nevetheless, if you want a simpler planning cycle, provided that you understand its ads and cons, you could go for Consumption Based Planning MRP.

Forecast Model in Demand planning and E book Sap trainingcourse

Dear Experts ,
I am Exploring differnt Forecast Model , like constant
model, trend model, seasonal model, trend and seasonal model, Croston method
with exponential smoothing, linear regression, and causal models with multiple
linear regression (MLR).
is there any SAP links or material or course availabe to learn more about Forecasting Techniques that we can use in Demand Planning in APO
if you have idea please help me to learn .. i am really starving for this techniques
Thanks in advance
Cheers & Thanks
Raj

Hi Raj
Below link will give you entire information on forecasting models, forecasting accuracy technequues etc,:
http://help.sap.com/saphelp_apo/helpdata/en/33/437a37b70cf273e10000009b38f8cf/frameset.htm
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.
I hope thos will help you.
Please let us know if you require any more information.

Customer Forecast Management vs. Collaborative Demand Planning

Hello,
Currently my client is trying to replace 40-50 raw excel format forecast which they receive from multiple customers with SAP APO.
They use a consolidated format and upload it into another 3rd party tool currently.
My question is which best suits the purpose in short term as they are very limited on resources. I would also like to know the difference between using Customer forecast management vs. Collaborative demand planning in this context.
Thank you all,
Sai.

You can use the GATP functionality known as Product Allocation for this scenario. This will basically mean that you need to maintain product allocations against each customer in your GATP planning book and every time you create a sales order in R/3, the quantity will be checked against the allocated quantity in APO GATP. If the quantity exceeds the allocated quantity for that given month, then sales order cannot be confirmed.
You will need to explore this funcionality in APO GATP and this should help your requirement.
Cheers,
Srinidhi

Forecasting Models in Demand Planning.

Hi experts,
want to know in details and also to practice various forecasting models in Demand Planning, from beginning.
please suggest.
Regards
Bhupendra

Hi Bhupendra,
There are various forecasting models to use in business like automatic model and manual model as a broad category.
In detailed, there are models like constant model, trend model, season models, trend seasonal etc.,
Forecasting models are very simple and mostly based on STATISTICAL TECHNIQUES. If you have sound knowledge in various statistical methodologies, it will be very easy to followup all the models.
Moreover, while selecting the best model for an organisation, one needs to study and identify the key performance indicators for improvement and accordingly the forecast model needs to be aligned.
The method to find this kind of model is the BEST FIT METHOD (it could be one or more or combo of it).
In demo systems or sandbox system, you can populate various data with various models and try to analyse the one which satisfies business requirements. You can also take the help of BUSINESS PLANNING ANALYSER to build the customised forecasting model which can be part of business side or from consulting side.

Interactive demand planning -statistical forecasting error

Hell APO DP experts,
We are implementing CBF functionality in demand planning. In /SAPAPO/SDP94 - Interactive Demand Planning, when we try to run forecast we are getting a message:
Not possible to carry out the forecast - no historical data
Message no. /SAPAPO/MA502
although the historical data is there.
Any info on this?
Regards
Pandit

Hi,
If you are working on SAP APO 4.0/4.1,
Check OSS Note 790517 - No error message "No historical data available".
Implement the corrections as mentioned in the message.

Transfer Demand Plan to R/3

Hi All,
I need to transfer the Demand Plan to R/3.
Please let me know the importance of Period Split profile in the transfer profile screen.
we are using the posting periodicity in the planning book.
What is the use of Distribution Function?
Is it possible to transfer the demand in days for first 3/4 weeks and then in weeks for rest of the period.
Your input/suggestions are highly appreciated.
Regards,
Prabhat
Edited by: Prabhat Sahay on Sep 29, 2010 3:37 PM

Prabhat ,
Period split profile is used when your demand plan is calculated in a particular periodicity (say month) and you want to see the result in ERP with a more detailed periodicity(say weeks or days). In case your demand plan periodicity is the same as the periodicity in which you want to see the results in R/3 then there is no need for a period split profile. As the name implies period split , splits the value to a finer level.
Distribution function is used to assign weightage to the different periods. We divide the value of a period equally so iam not very sure about the distribution function concept. But i think , if you have demand plan of 100 CS for a month and you are splitting it into weeks (defined in period split profile) , and decide to give more weightage to weeks 1 and 2 compared to 3 and 4 then the distribution function comes into play . Not sure about it though.
Also refer to consulting note 403050 . It talks about releasing forecast to sNP, but then the concept of period split profile / distribution function is the same irrespective of the target to which the demand plan is released.
Thanks

Release of APO Demand Planning to R/3 Demand Management

Hi All,
Is there a way to release the forecast in Demand Planning in APO to R/3 Demand Management without passing overwriting the historical buckets in R/3. I have created a special data view that does not contain any historical weeks. However, if we are in week 2 of the month, it overwrites week one of the month in Demand Management with a 0 value when we execute the forecast pass to r/3 job. I don't want to overwrite week one and we actually want to keep the old value there, How can we prevent this from being overwritten?
I have created a data view that does not contain any historical buckets and I am using this in the
Regards,
Rumi,

Hi,
For releasing from DP to ECC , you have taken care of:
○ A future planning horizon only
○ A planning buckets profile with one periodicity only.
I assume you are using "Week" bucket , please confirm.
In SAP ECC Demand Management, planned independent requirements are created in the same buckets as those of the data view on which the mass processing job is based.
With above things in mind, it not clear why APO DP release shoud overwrite historical week data, unless you are releasing in monthly buckets rather than weekly buckets.

Assigning cvcs to forecast profile (in mass)

Hi All,
We have loaded thousands of new CVCs into Demand Planning and would now like to assign then to a single forecast profile. I thought that it was possible to do this via a background job since this contains a selection profile and a forecast profile. However, after the job completes, I do not see an assignment. Is there something that I may be missing here (a setting) or am is there another way to assign numerous CVCs to a forecast profile?
Regards,
Rumi,

Datta,
I am familiar with this transaction but I am not sure it is the best way to solve this problem I have described? Also, if new CVCs are generated they need to be assigned to the master profile via the background job. I don't want to have to use /SAPAPO/MSDP_FCST2 to do this. Also, I don't know how you can assign a forecast profile to 10000 or more CVCs in this transaction?

Releasing demand plan from DP into custom categories in SNP.

Hi Gurus,
I need to release the demand plan from DP into SNP custom categories Z1 thru Z4. The key figures that I mapped to these custom categories are created in a non-standard planning area (copied from 9ASNP02).
I am able to release the demand plan using category FA only. Can anyone help me in releasing demand plan into these custom categories in SNP.
Thanks,
Shiv.

Shiv
I did a F1 help on target category field in tcode /n/sapapo/mc90 and this is what i found
For the release of the demand plan to Supply Network Planning, you can specify a category that tells the system which category of orders to release to. An entry in this field is optional, but if you do enter a category it must be a category that represents sales orders or forecasts, such as FA or FB.
You can also release to categories you have created yourself. This allows you to distinguish, for example, between different forecast priorities.
The system proceeds as follows:
1. Has a category been entered in the release profile? If yes, this category is used.
2. If no, has a category been set in the definition of the requirements strategy in Customizing? (You define the product's strategy in the Proposed strategy field on the Demand tab of the product master record.) If yes, this category is used.
3. If no, category FA (forecasts) is used.
So as the F1 help says in the release transaction /n/sapapo/mc90 did you try giving the custom categories ? Also i have one more idea - after the forecast gets released to category FA , copy it to a key figure that is assigned custom cateogries Z1 to Z4.
But just want to understand something . Why do you want to release it to a custom cateory instead of FA ? How are you going to handle the consumption of forecasts by sales orders if you release it to custom category. I think releasing it to a custom category will make your process more complicated since you are altering the standard SAP functionality.
Thanks
