Forecast bias in APO DP

I am using APO DP V5.1.
Statistical forecasts show a consistent positive bias.
Can anyone advise on how I can address this point?
Thanks...

There is nothing such an automatic bias correction in APO DP. If you see bias in the forecast, either the forecast model chosen is not the right one (in this case, you should change the model) or there is no right model for your data (in this case, you should forecast manually).
Example for the first case: data with positive trend, forecasted with a constant model will show consistent bias. The solution in this case is to change to a trend model with good parameters.
hope this helps,
Pablo

Forecast Consumption in APO- No Data Available in Product View

Hi Experts
I facing some problem in Forecast Consumption in APO. The APO system is connected to a R/3 system. So data relevant for Forecast consumption comes from R/3.
The allocation indicator in the requirement class assigned to the strategy maintained in the product master is set as " no consumption with customer requirement". and the same is transfered to APO.
I have the changed the settings in APO and here are the setting maintained in APO to enable Forecast Consumption.
Product Master Setting:
a) Consumption Mode: 2 ( forward and backward)
b) Consumption Period: ( 30 days both backward and forward)
c) Strategy Group : 20 and assignment mode is set to "Assign customer requirement to planning with final assembly" and category group has sales order - BM
d) The check mode setting in the ATP tab is set to "Assign customer requirement to planning with final assembly"
I have a forecast for today's date and a sales order transferred from R/3 for the same date. But I do not see any data in the Forecast tab in the product view ( /sapapo/rrp3 Tcode)
Please let me know if I am missing any setting in APO. Or the SAles order carries the strategy information from R/3 and influencing the consumption any way.

Hi,
What is your Forecast & Sales order quantity? If these are same then sales order consumed forecast, so you can not able to see in the rrp3.
Second thing try to increse the forecast quantity than sales order quantity & then check it.

Forecast Deletion in APO

How can we delete the forecast values in APO?
Thanks

Hi Siddharth,
For reorganising the forecast values, you can use /SAPAPO/MD74 - transaction code. Make sure before you use in live system, test in dev system how it works, understand the functionality and then try in live system.

Negative Forecasts appearing in APO-DP

Negative forecasts appearing in APO-DP against some brand/packs.Any reasons why????

Hello Kailesh,
Sometimes the planning book doesn't show what is saved in livecache. This is especially true when you have some default macros which gets executed when you load data. The default macros will run and therefore the planning book will show the result of the macro computation and not exactly what is saved in livecache. For example, if you have a macro in one planning book which computes the Net Forecast = Stat + Adjustments. Every time this planning book is run Net Forecast gets computed and also gets saved when the user clicks the save button. Now, imagine what will happen if stat or adjustments gets changed somewhere else (e.g. thru another planning book or thru stat forecasting). When you go the first planning book in display mode, you will see that the data for Net Forecast looks "correct". However, this is not what is saved in livecache.
I suggest you try to check out your data using a planning book with no macros. You can also check out using RSA3 using the export datasource of your planning area. Both of these methods will show you what data was really saved in livecache.

Forecast creation in APO

Hello,
do you know whether transaction /SAPAPO/DMP2 can be used to create Forecast in APO - based on dependent demand in an inactive planning version, we would like to create forecast in the active version. When I execute DMP2 the log always says "No planned independent requirements generated". Do you have any experience?
Thanks and regards,
Anke

HI Anke,
i do have the experience while working on CBF..
we have generated PIRs for componets for which dependent demand exists..
make sure that your components have strategy 10 in MRP3 page tab..
category in the DMP2 transaction should be AY and AZ.
try this..
I am working on the latest verion of SCM...let me know whether you are able to use the same settings..
i will help you in this regard if the above settings do not crack your problem..
regards

Forecast Transfer from APO to R/3

Hi All,
We have an issue wherein we wanted to transfer the forecast to R/3 for non-working weeks.
We are planning in APO in weekly buckets. So, when we transfer the forecast for a week which is completely marked with non-working days at R/3, we want the forecast for that week at APO should get transferred to the rest of the working days of the respective month/period.So we dont lose forecasts for that week which are planned in APO.
Do we have any settings by which we can force the forecast to push to the other weeks which are are haing work days in a period.
This is how the system is behaving when we have a non-working day at R/3 in week. If I have 5 day a week and one day of that week is a now working day. So, when I transfer the forecast fromAPO to R/3, all the quantity for that week in APO is getting pushed to remaing 4 days of a week. the same functionalitywe would like to have if complete one week is non-working week, the APO data for that week should get transferred to next three available weeks.
Hope I was clear. There is a business reason for this. the business/demand planner can plan their material even though the plant is shutdown for a week since they may want the forecast should get consumed by the Sales Order delivery. The Sales Order delivery can consume the existing stocks.
Any help is appreciated.
Regard,
Rakesh Wade..

Hi Rakesh Wade,
Can you check "days in period" option in master forecast profile, i hope here we can adjust the days and recreate forecast for remaining days.

Vinod

Inconsistent forecast consumption in APO and R/3

Hi Experts,
We have a couple of issues with consumption in our system.
We have a situation where APO is showing us consumption in the /SAPAPO/DMP1 view but no consumption showing in the planning books and the RRP3 requirements screen. Interestingly, when we go and change the sales order in R/3, the consumption then gets triggered in APO. So there seems to be some kind of delay and the consumption seems to be lagging a step behind or somehow a trigger isnt hapenning first time around.
The other is more a question...
If you do the F1 help on Fwd consumption in APO and R/3, it tells us that in R/3 consumption is based on workdays as defined by the factory calendar whereas in APO, it talks about consumption considering calendar days and not workdays and that its not possible to define a calendar to make it work with workdays.
We have fwd consumption set to 2 days and we have noticed that if e.g the order comes on a Friday, consumption gets lost due to the following two days being Saturday and Sunday. Whereas in R/3 it jumps forward and consumes Monday and Tuesday and ignores Satuday and Sunday (We are using 5day calendars). This is causing a big headache and consumption is all over the place.
any ideas?

OK, I have found the solution to half the problem. It was a system bug and the last sales order wasnt being consumed and there is already a note out for that.
Still confused about the workday vs calendar day issue in R/3 and APO. How do we align the two systems and get the consumption happening in APO for 5 days and not 7 days?

Usman

Mass deletion of Forecast & Backlog Confirmatin from APO

Hello All,
Is there any transaction to delete the backlog Forecast & Confirmation from APO. Can MC75 transaciton in R/3 delete the Forecast from APO in mass. In current senario I am doing manual deletion of backlog Confirmation every month. Can any transaciton help me in same ??
Thanks in advance

Hi Mohit,
You can use TCode- /sapapo//rlcdel, which is the same as the report in SE38- /sapapo/rlcdelete. chose 'select object by categories'. Put the order category as F*, put the date range, planning version, product and location and execute. This will delete the forecasts for the particular product/loc.

Tables to store Forecast in APO

Dear All
we need to pull the Forecast data in third party application. we need tables in which the forecast data is stored in table.
I am not APO expert or APO user, but want to pull forecast data from APO for my application.
APO consultant told me that, their data is stored in Planning Book, then how one should pull data from planning book
Regards
Saurabh

Hi,
As per business scenario,Once forecast done then they will take the back up fron the planning area.
Normally in APO data is stored at live cache level at internal table so you can't extract the dat fron APO.
Most of the cases they will store the data at BW infocube and then they will manupulate the data from BW cube.
So please create the BW cube and store the data in BW cube and get it from cube,BW cube is inbuilt functinality of APO.
Create Datasource from planning area and create BW cube and assign the correct sorce system.

Prabhu

User exits/BAdIs for Forecast consumption by sales order

Hello Experts,
My question here is: When Sales Order either new or change comes from ECC to APO, what are key fields considered for Forecast Consumption? Is requirements strategy is considered from location product master or Sales Order brings own data from ECC into it's own structure? I have read from SAP help or documentation that Sales Order coming from ECC does not use requirement strategy from Product Master. Rather it get its own fields like planning strategy/group / requirement class from ECC. It uses location product master only to get consumption parameters like forward/back word consumption days. So I am thinking to use some user exits or BAdIs to enhance the incoming sales orders to consume separate forecast categories in APO.
My requirement is:
For the same one product we want sales orders (can have two different order types or identify by a custom field) to consume two different order categories (ie. FA & FC) by enhancing incoming sales orders. So we have regular 1)Forecast key figure which is 'FA' category and 2)Forecast Additional key figure which is FC category. When we release two separate forecasts from DP we release into these two key figures and categories. Now we want incomping sales orders to consume these two categories separately when our sales orders are having two different order types (i.e OR and ZR).
I want to kow what way we can acomplish this? Are there any user exits or BAdIs for this purpose?
I looked arount BAdI /SAPAPO/DM_BADI_CSP and I am not quite sure it's going to help. Are there any others?
I appreciate if anybody explain me the process?
Thanks in advance!
Raj

Standard Logic --- Whatever plant is visible in the Sales Order, the sales order will appear under that Product Location in SNP
There is no standard way of making the sales order visible in another location.
Depending on your requirement(Ex: Forecast Consumption, planning etc),using APO-BW we can simulate the requirements in the other plant which can be a nightly run and not immediate.
Now coming to your question, if the delivering plant is A, how does ECC Delivery document know when the sales order has plant B that the delivering plant is A.
Can you be more specific.

Preparing Forecast in SAP R/3

Hi Gurus,
Good Morning.
I am trying to prepare a Forecast Plan for next 6 months based on the Sales History for Past 13 weeks. The solution which i was thinking of is to prepare a Custom Sales Forecast report in SAP with the Sales History over the 13 weeks as the basis for the calculation , spread it out in monthly buckets and then upload it to the Planned Independent requirement table (MD61)
If at all if i dont use the above option , In the system if i extend the forecast view then we can plan the Total Consumption over there , ther total Consumption does looks for all the Sales Order over that particular period? and also how can i get the data in the the forecasting to be transferred to the Planned Independent requirement table ? It would be great if you are able to provide some Configuration/Setup details.
Thanks in Advance..
Thanks
Balaji

Balaji,
It appears you are asking about R/3 forecasting, and not APO. You don't have to write a custom report, SAP standard functionality provides your requirement.
Standard methods in R/3 to arrive at Planned independent Requirements through a forecast are Material Forecasting (which creates forecasts based on historical consumption) and Sales and Operations Planning (which can forecast based on anything you design).
Simplest to implement is material forecasting. For most companies, FGs consumption data is more than adequate to provide realistic forecasts.
Once your forecast is done, using either Material forecasting or SOP, it can automatically be converted to Planned Independent requirements.

Creation of GUID in SAP APO

Hi everyone.
I have been tasked with creating forecast data in APO. This involves the creation of the entry in table /1APO/S1000000nnn (derived from table /SAPAPP/TSAREATE using planning area). After this entry is created I need to create the forecast model assignment entry in table /SAPAPO/DP_FCST2.
I am achieving this by opening the client and using SE11 to load the data.
The problem I have is that, even after an SQL trace, I still can't find out where I can get the GUID that I need for the creation of these entries. Does anyone know which Function Module to call that will create the GUID and the /1APO/S1000000nnn entry as well? Are these separate FM's or is there one that does both tasks.
Any help will be appreciated.
Regards
Dave.

Forecast Consumption in SNP for shipped qty's

Hello experts,
I got a question for forecast consumption in SNP and whether forecast stays "consumed" or not after a customer orders gets shipped (Post Goods Issue).
My example is: I have a weekly bucket forecast qty of 100 in DP and release this to SNP. Now in SNP planning book I have 30 units of open Customer Demand against it ... means I have 70 in Forecast line (30 units got consumed correctly). Once I create a shipment for the open Customer Order of 30 units in R3 the situations remains the same .. but if I post the Goods Issue now on the delivery document the Customer Demand disappears (which is correct) but my Forecast line increases again from 70 to 100. I thought forecast consumption in APO would "remember" the already shipped quantities ? I know that you can reorganize open forecast but want I'm looking for is the standard R3 behaviour of keeping already shipped qty's as consumed. Can anybody help here or explain ?
Regards
Thomas
Using SCM5.0

Hi Datta,
I checked the note - there is only point 9 in the list saying:
"9. During goods issue for the delivery in R/3, the forecast is always reduced to the date requested by the customer. In addition, overdeliveries are ignored."
Unfortunately this doesn't explain how it works or needs to be done to have FCST consumption happen in APO_SNP based on shipped qty's. In my case FCST consumption works okay up to the point of posting the goods issue on a delivery document. I wonder if there something I need to activate somewhere to have this working since I can't see any "with drawn qty" in APO.
Any other hints ?
Regards
Thomas
