Forecast accuracy check in R/3 ECC 6.0

Folks,
We've designed a Flexible Plng solution for our clients to address a very complex reqt. But as it stands, any good design of Flex Plng (SOP for that matter) is incomplete without a very reliable way to forecast & keep bettering the forecast via regular forecast accuracy checks.
To that end, wanted to know if anyone has worked with tools within R/3 Forecasting that allow us to carry out robust forecast accuracy checks. If yes, pls share your inputs on how this can be achieved..
Inputs in this regards will be greatly appreciated
Cheers
Josh

ATP check for delivery in ECC & Sales order ATP check in APO

Hi All,
Can we do an ATP check for delivery in ECC , but for the same set of Materials- Plant combination , the ATP check when a SO is created should happen in APO .
We do not want to remove the Business event 'B' which is meant for delivery in APO . For some materials we need APO ATP check to happen for delivery & for some it should be in ECC & for SO the ATP check should happen in APO .
Even if we do not have check instructions pertaining to Business event 'B' & a particular check mode (for the materials where the ATP check for delivery should happen in ECC & SO check to happen in APO) , when we are doing an ATP check for delivery , it is still pointing to APO ATP check rather than ECC check .
Any pointers for this is highly appreciated.
Regards
Surendra

Hi Surendra,
For SO, business event is A and for delivery it's B. When integrated with ECC, the check rule in ECC points as biz event in APO.
You can control ATP check by customized settings for check rule in ECC.
Also, by setting requirement class and requirement type in ECC, you control check mode in APO. So, even if you dont define for check mode in APO, the system might refer from ECC for the ATP check settings. Look into your ECC customization for how requirement class is derived and settings for requirement type. (based on MRP type, strategy grp and Item cat).
I'm not sure how you can control ATP to happen for some sales orders/deleveries in ECC and for some in APO, since check mode is mentioned in material master.
However, there are ATP BADIs (business add-ins) available in both ECC and APO, whch can serve your purpose.

Bipin

Forecast accuracy report

Hi All,
Would like to know if there is any forecast accuracy report in ODP to verify that the forecast is valid. To give an example, if I collect the demand number and upload the forecast to calculate the forecast to order PO. We should know whether the forecast uploaded is valid i.e. is it possible for Oracle to state that this forecast is not correct according to the trend. Is there any exception report to state this kind of behaviour.

Availability Check from CRM using ECC / Assembly Order

Hi,
we're using an ATP Check from ECC to CRM 5.0. As described in the SAP Notes, assembly orders are not supported in this ATP scenario.
Does anybody have experience to overcome this (without implementing APO or creating the orders directly in ECC)? Any enhancements / work arounds?
Thanks
Anke

Hello Anke,
you cannot have both, ATP check in CRM during order change/creation and in ERP when the order gets replicated to ERP-SD.
But when there is no ATP check used in the CRM at all (for the current item category), and the order gets saved in CRM and replicated to ERP, during this replication and order creation in the ERP-SD the regular ATP check in the SD order can run as usual, of course.
This means the scenario can be setup without ATP check in the CRM, but having assembly as usual in ERP-SD. Only the immediate information about the confirmed dates/quantities from the assembly order would be missing in the CRM order.

Thomas

Where to see Forecast in ECC released from APO DP

Hi Experts,
we are releasing forecast data from APO DP to ECC.
can anyone please let me know in ECC is there any table and transaction where we can check the released forecast from APO.
Other than MD63.
Thanks in advance.

Hi,
You can check it in MD63 - Display Planned Independent Requirements
Or Menu path:
SAP Menu->Logistics->Production->Production Planning->Demand Management->Planned Independent Requirements->Display

To Turn OFF ATP check in APO-GATP Instead do locally in ECC.

Dear SAP Friends,
Currently for Sales orders & Deliveries, we have ATP Check (Allocation Check + Product Check) happening in APO-GATP. We would like to turn-off ATP check in APO-GATP, instead want to do only Inventory Check in ECC locally.
We want to do above for few particular model/plant combinations and not for all model/plant combinations. Meaning APO-GATP will still be used for many other APO relevant Model/Plant combinations.
What are the changes required to CIF Integration models u2013 Salesorder+ATP Check, or any other IM. Any changes specific to material master in ECC - like MRP Controller, ATP Group, Strategy Group or any config changes on APO side.
Please guide me with stepwise instructions.
Appreciate your help.
Thank
Satish
Edited by: SatishW on Jun 18, 2010 9:33 PM

Hi Satish ,
I am not an expert on GATP but logically what I can suggest following steps :
1.As you want ATP check to happen in APO for few codes, you will have to Select/Tick 'Material Independant Object' - ATP Customization in CIF IM , so that ATP customizing settings are transferred to APO from ECC.
2. But at the same time you need this ATP check to happen in ECC locally and not in APO for certain products, then in other CIF IM you have to select 'Material dependant objects '- ATP Check where you can set the filter/exclusion on those codes so that the ATP check does not take place in APO.
3. Also like as R/3's backorder processing, in order itself you can set as the ATP check to occur in R/3 and not in APO.
Hope this helps...

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.
Regards
Datta

Forecasting Strategy feasibility.

Hi All,
I need to check feasibility of one particular scenario.
I have 100 Materials for which I need to Forecast. I need to calculate best Forecast strategy for all Material with calculation of Forecasting Error.
Correct me if I am wrong: We can get the Best Forecasting Strategy by adding all the Univariate Profile with different Forecasting Strategy in the Composite Profile Tab.
Now my requirement:
1. I have 100 SKUs. Each individual SKU has different historical data. Now I cant run Univariate Profile for each individual SKU separately and also run the Composite Profile to find out the best Forecast. I need to find is there a way to run the Forecasting Strategy for all SKUs separately something like mass run together?
To be very precises i need to run Forecast Strategy for all 100 SKUs for their individuals Historical Data simultaneously.
Thanks,
Best Regards,
Bhaskar

To comment on the statement: If you are looking at performance at Go-Live you might be better off with Auto 1. Auto 2 takes more time
some more ideas if you want to explore them
your final solution will depend on the weightage of the performance of the forecast run vs the accuracy of it
If you are focussing on the performance use Auto 1 during go live. It will definitely be faster.
If you are looking at accuracy go for Auto 2
You also dont have to use a one-size- fits-all solution for the million CVCs.
Also your forecasting level will make a difference. You might notice dont have to forecast at the most detailed level or for all the million CVCs all the time. Check if all the characteristic levels are pertinent to your forecasting.
You can also forecast at a aggregate level depending on the product characteristics. epending on the business you should look whether a top-down forecasting approach can be adopted vs a bottom-up approach that you are looking at. You can use KF disaggregation to let the forecast take its proportions
You need to be able to group your products at least into 2. You might also use the other characteristics to group these
examples of Group 1:
Critical Products were forecast accuracy matters
Products with Trend, Seasonality
Products which will have an immediate visible effect post go-live
High value products
Regions where not going out-of-stock might be important
use Auto 2 on Group 1
Group 2:
Rest of the products
Use Auto 1

Forecast Quantity Reduced to 0 by ASCP

Hi,
I'm running a Un-Constrained ASCP plan in 11.5.10 version.I have a forecast defined at Source for qty-300 in bucket-october-2010.I'm able to see this forecast entry in Collection workbench for 300 nos.
After running ASCP plan , the plan has shifted the sugg due date to plan start date.This is expected as the customer runs a customization to back-off the forecast date by Leadtimes.
But the qty is changed to 0 from 300.I'm not able to see any consumption details for this forecast entry.And even the 'Consumed Forecast' field in the PWB doesnot show any value , it is blank.But I have a SO , for qty-300 on the same date.if this SO has consumed the forecast , this should be visible in the consumption details.
Is there any other method to check the consumption in ASCP plan, other that the PWB-UI.
Even forecast expiration is not happening as it is a un-Constrained plan( ASCP userguide states that Forecast Expiration happens in a Optimized ECC plan , and again i dont see any value in the 'Expired Forecast' field in the PWB.
What are the other functionalities , that would reduce the Forecast qty.
Has anybody faced this similar issue earlier.
Thanks in Advance
Edited by: Bhubalan Mani on Aug 16, 2010 8:59 PM

Hi Partha,
Pls find the detrails below.
The Hook runs after Data collection and before Plan.SO the due date of the foreast is over written in the collected data.
In source the Due date of the forecast was in October'10.Due to the Intransit LT of 42 days , the due date was pulled in to August-10.
And the MRP parameters,
Include MDS Days
Include Past Due Forecast ,
both are blank.If its blank , what i understand is, there is no restriction to the Past Due forecast that is considered in the plan.
Please let me know , If You need any additional information.
Thanks

Goods Movement Not allowed(XWAOK) check box - for SRM Reservations.

Dear Experts,
We are working on Extended Clasissc sceanrio however certain materails we are creating reservation switching from ECS to Classic Scenario. System is Creating Reservation successfully in backend but Goods movement reservation allowed (FIELD XWAOK) check box not checked only for SRM Reservations
Please note that ECC reservations checking this checkbox automatically based on Configuration. Is there any setting we have to do in SRM to pass the check box value to ECC? or How Can i check what data is passing from SRM to ECC......
Thanks
Ravi

Dear Ravi,
Could you please check if you have added the value '201' against the attribute movement type (forgot the attribute name) for the purchasing group or user group who created the shopping cart in SAP SRM. Once you have added the attribute, the problem should be resolved.
Thanks and regards,

BP not getting replicated from CRM to ECC server

I am currently facing an issue, it seems like the replication of BP from CRM to ECC is not working, I have created a few business partners in CRM for which the BDOC got processed completely but when I go and check these on the ECC side, I am not able to find these BP. Can any one suggest what might be happening.

Thanks a ton for the note number Denis, I am looking into this and would certainly revert back to you if this works. Just to explain you the excat problem that Im facing as of now.
I have a few Business partners which we are not able to replicate from CRM to ECC, I have tried to debug the queue and find out what the reason might be, i could see that everything got processed successfully at the CRM side, the issue is when the BDOC reaches ECC, there it gives me a error that "NO UNIQUE JURISDICTION CODE CANNOT BE DETERMINED" area as "TAX_TXJCD".
If you can suggest anything new based on this information please let me know, in the mean time I will try the note that you had provided and would get back to you very soon.
