MRP Forcasting

Hi
I have a specific MRP requirement.
1. For example if last 6 months consumption values are from Aug 09 to Jan 10 are 200,300,200,300,100,400... then forcasting out put should be 20% more than than the calculated average. Here it should be 250(avg of last 6 months) * 1.2 = 300.
2. Forecasting should be for next two months and it should be -
for Feb -> 300( as explained in point 1)
for mar -> avg should be taken from (consumption values of sep 09 to Jan 10 and forecasted value for Feb10) .. so output should be 1400 divided by 6 then multiplied by 1.2 - >280
Please suggest which forecasting model to use to satisfy both requirements.
Thanks,
Yuvnish

Hi Yuvnish,
This kind of algorithmic logic that you want to apply has nothing to do with forecasting by itself, but rather with Demand Planning in it's wider context.
For this you need to use one of the system's demand planning tools, like SOP or DM in ERP, APO/DP. There, you can run statistical forecasting, get it into the planning table, and then apply this kind of calculations.
Hope that this helps.

Manipulating matrix with XML

Hi!
I am implementing a form that looks and works like Frocasting in MRP. So, there are sometimes a lot of columns in matrix (more than 1000). I have to generate such matrix, put data there, read data. It will be like a self - made document in B1. The problem is that generating the columns, updating them an reading data is vee-e-ery slow when i use SDK objects. But the MRP Forcasting functionality in B1 works very fast. I suppose that B1 uses XML matrix manipulating. The question is - do someone have the info or maybe tools that will help me? Because generating XML strings "by hand" is very complex. And I'm a newbie in XML Do someone please can help me with the info?

David

Thank you Gianluigi!
I was able to add Matrix & Columns via XML, but I cannot delete columns
Could you please review my thread [here|Remove columns from Matrix using XML;.

Processing indictor- MD06

Hello,
I have a query for you.
I did read about it but did not get any good clue, so...
We are running MRP (forcasting) and MRP controller set the indicator "then it display at the bottom" - The MRP list was already processed on the xx date.
My question is, Now when this indicator would reset again?
When I am running MRP again, even after PGI, it remains the same. I checked after Mi10, MIGO and even changing the PO delivery date but same....
Please suggest.
Regards,
JPS

Hi JPS,
Forgive my cavalier attitude. I have never found this functionality useful.
If you have set the indicator, when MRP runs anew, It will compare the exceptions between the new MRP list and the old MRP list, using its own algorithm. If it finds a match, It will internally tag those same exceptions in the new list as 'Old exceptions' and will retain the indicator. At this point, some planners filter MD06 to review only new exceptions.
If you have set the indicator, and MRP runs anew, and it compares the exceptions between the new list and the old list, and it can't find any matches, it will reset the indicator.
When I was a planner, my experience was with finished goods, where there were usually dozens or hundreds of rows on each MD05 screen. There were typically dozens of exception messages. If I set the indicator, it almost never got 'un-set in any reasonable time frame'. And, business requirements didn't allow me to ignore the old messages for very long, anyway. My bosses always wanted an action plan, to be updated regularly.
I suppose if you have a less frantic MRP, e.g. you have a material/plant in MD05 with only one or two exceptions, and you choose to ignore them, then perhaps it makes sense to set the indicator, and then only review new messages.

MRP Runs With Out Forcasting & With Miximum Level.

Hi All,
I Have a One Finished goods Item Which is Marked as Inventory Item and Sales Item.
My Inventory Management is Werehouse Level
So This Item I have a In Stock Quantity is 40 at my werehouse Minimum Quantity is 50 and Maximum Quantity is 400 Both
of this minimum and Maximum Quantity will Put Manuly by me at Item Master.
I Don't wnat to Use the Forcasting For Any Item.
I Want to Run MRP For This Item at Maximum Level
If Item Goes down to minimum Inventory Level for Example: In stock Is 40 at that time I wnat to Run MRP
My Requirment is when I run MRP System Gives Recomandation to me a 360 Quantity
Meanse { Maximum Quentity-Instock=Recomandatin } [ 400-40=360]
Is It Possibal or any one have solution for this Requirment then Pl z send it to me.
Vikas

Hello Vikas - I doubt also that you will find an MRP system with that, however, here is something you might want to fool around with as a start to creating an alert message or daily SQL run...
SELECT
T0.[ItemCode],
T0.[MinLevel],
T0.[MaxLevel],
T0.[OnHand],
T0.[MaxLevel]-T0.[OnHand] AS 'Sugg Order'
FROM OITM T0
WHERE
T0.[OnHand] <= T0.[MinLevel]
AND T0.[MinLevel] <> 0
At least this will give you a list of products you can look at until you can find something else.
Maybe this will help? I hope so...

MRP with PD, it doesn't want to show me UNPLREQ based on forecast.

Hi guru's!
I work on a new project. I use PD as planification type.
The target is to take in account in MRP only the PLDORDER proposals (not converted in Production Order), the companie update the stock manually with MIGO to erase PldOrder at each new MRP run. (They don't want to create and manage master data as componants, BOM or routings)
Material master have forecast view, and historic of consumption are copied from past sales results.
They want to use a dynamic safety stock, which is calculated thanks to MP38. This lunch calculation of forecast collectively to create UNPLREQ in MRP every month based on the historic.
I've done the customizing, and my MRP work correctly : UNPLREQ was here and the update of stock with MIGO was good (after a MRP run PLDORDER were erased).
But after some change in customizing, I don't retreive my first situation, in fact UNPLREQ (neither none requirement) are shown now in my MRP.
I don't retrieve my mistake in customizing... Please, is somebody know where something can change the fact that you can't see the requirements in MRP??? the problem not comes from my material master data, i'm sure of that!! it's in the customizing.
I hope you have all need to answer.
Thanks in advance.
JC

Dear R.Brahmankar,
Your note, even if it's for an old version of SAP, is helpfull for me. I will try to create my own planification type with the same configuration than PD but changing forcast to mandatory. I will test it and we will see after...
In fact, before my example "crash", I have tested plan. type VV and VM. So, as forcast is mandatory in this case but it's not work too, there is something which is "bizarre"!! Moreover, I've try the two way of enter forcast historic (non planned consumption and total consumption) for my article in forcast view.
JH,
My requirement was not replace in independant requirement (MD61).
Thanks, I will re-post something if I find a my mistake.!!

Usage of MRP Procedures in Consumption Based Planning during Implementation

We have following procedures in CBP:
1. Reorder Point Planning- Manual and Automatic
2. Forecast based Planning
3. Time phased Planning.
In SAP implementations, which of these procedure is mostly used in companies in real time.
Though the CBP planning node is in MM SPRO and MM study material also contains CBP. During implementations, for CBP the responsibility rests with MM consultant or PP Consultant or both.
Please share your views on this.

Dear ,
Let me share my views on this as we are runing CBP-Forcast base planning in our trading business .
Decision on CBP-Forecast base planning method are based on the following criteria
1.Stockable and low value material
2.Fast Moving with good sales pattern ( Trend Analysis , Historical Trend analysis on Product Group , Statistical Sales analysis )
3.Inventory turn around based on the monthly physical inventory and sales
4.Good service level percentage over an period .
5.Consumption pattern .
Decision on CBP-Re-order point planning method are based on the following criteria
1. Material which are higher valu and Non Stockable
2. Customer oriented traded goods
3. Strategic vendor with good Sales pattern .
4.Re-order Level based on Sales Forecast (Manual or Automatic )
In SAP implementations, which of these procedure is mostly used in companies in real time : It is based on the business requirement (Trading /Manufacturing ) .Mostly Trading business goes for CBP-Forecast Base planning method (MRP Type -VV) IF THE MATERIALS HAS GOOD CONSUMPTION PATTERN OVER A PERIOD OF TIME .
MRP is both the part of Supply Chain Planning and Manufactruing . Material master parameters are maintained by MM .CBP is one kind of MRP where Demand Management comes into PP whereas after MRP run , procurement proposal handeled by MM.So there is no hard and fast rule that it is only part of PP.It is the combination of MM and PP.
Hope this will help you to analysise your requirement .

1.Now how to run MRP in this case ? What are the MRP view parameters need to mainatin in this case
2.Will I need to use Forcast Base Planning VV here .
3.Will need to calculate Safety stock/Re-order point by the system using the Forcaste model in Material master Forcasting view with various control data ?
4.What will be the lot size ?
Or we can use SOP using Sales Order .How to acomplishe that ?
If anybody can help me out ,it will be highly appreciated
Regards
JH

Hi..
1.Now how to run MRP in this case ? What are the MRP view parameters need to mainatin in this case
MC87 and transfer through mc79..THis will create PIRs.. Then in MD02 you can run MRP..THe planned delivery time is an important parameter...
2.Will I need to use Forcast Base Planning VV here .
It is upto your plan.. If u wish to have, mention the forecast model in Material master
3.Will need to calculate Safety stock/Re-order point by the system using the Forcaste model in Material master Forcasting view with various control data ?
4.What will be the lot size ?
Use EX..

PIR -MRP Requirement

Hi
I have a Req , i Will get a Forcast req from 2 plant 1000 and 1100 to 5000, with special procurement Key Production In plant 5000, but req will be directly enter in the 5000 req plant VSE req type, later the req plant will rice SO through STO , it will take out the material from 5000, plant ,
So my req is when ever i will enter req qty in PIR in the same date for DIff plant 1000 and 1100 in PIR with diff version, when i will run MRP , it is creating a single req for eg(1000 req 10 qty and 1100 req 20 on 20/02/2010, when i will run MRP it is creating single req , so my req is it should create diff req with like 10 and 20 ,
I used lot size lot for lot order qty,
Please suggest,
Reg
Madhu

If I follow your example it sounds like you're getting one requirement for 30 and you want two requirements (one for 10 and another for 20). If that's the case, try setting the individual/collective requirments indicator in MRP 4 view to 1 (individual requirements).

MRP Error

Hello Experts,
We had run MRP wizard agains Forcaste senireo.
After save ,Order recommendation create numbers of production order and purchase order
But when we
               1.Create Purchase order then show me Error Could Not Commit Transaction(ADOC)
               2.Create Production order then show me Error No Matching Record found 'Product Tree'(OITT)
How can we solve it ?
Thanks And Regards-
   Krishna
Edited by: Krishna Gopal on Mar 16, 2009 12:05 PM

Hi,
Error Could Not Commit Transaction(ADOC
The issue reported may be probably related to approval procedures.
Could you please ask the customer to try the following:
Check which approval template is used for Purchase Order.
Log on with the approver user (designed approver in the template).
Go to the Approval Templates Setup window, Terms tab.
If the radio button 'when the following applies' is checked, please
check if any box was checked on the 'Choose' column and if the
Ratio 'Undefined type' is selected.
If so, either select a ratio and define a value, or uncheck the box.
Check the last line in the Terms tab ('Undefined type') and make sure
it is not checked.
Update.
Also please check the stored procedure code if any used by the customer
for this form.
For your second error
No matching records OITT run the following query and check if you are getting any results
====================================================================
Select Oitm.ItemCode, oitm.TreeType
from Oitm
where Oitm.TreeType <> 'N'
and Oitm.ItemCode not in
(SelectOitt.Code from Oitt)
=================================================================

Consumption Mode in MRP using reservations

Hi Gurus,
I am try to use the consumption mode found in the MRP setting if SAP.
My scenario is as follows:
1) Did a forecast of a material for 3 months
2) Created a Reservation between does 3 months
Problem:
1) No compensation was made to any of the forecasted quantities (i.e if forcasted quatities was 100- and the reservation was 20-, the forecasted model remained 100- and a reservation of 20- came up when MRP was run)
Expected Results:
1) Forecasted quantity 80- and reservation 20-, i.e. total 100- not 120-
Any ideas,
Thanks,
John.

Dear Uday,
Your question is related to delivery date proposed in the Sales Order processing. This has nothing to do with the consumption mode in the material master. Instead the delivery dates are proposed as per total replen lead time and inhouse prod time from MRP views.

MRP Custom Order Interval

We have an Item set with an Order Interval of Six Monthly, by using the 'Every X Days' option and entering 180 days into the no. of days field.
When running the MRP wizard however, the recommendations report suggests raising a purchase order every month for this item. It does not seem to be consolidating the orders by the order interval that we have entered.
Does anyone know why this may be happening?

The every X days i refer to is the order interval on the item master data planning tab. This field is a drop down box, an option of which is to 'define new'. We have defined a new interval and used the 'Every X days' option to input 180 days.
I have managed to recreate the issue in the Demo database. The horizon was set to todays date until the end of august, which automatically sets the end date to 03.09.10 (last day of the week).
I have not used sales orders at all, unticked the box in step 3. I have used a monthly forcast that generates a requirement of 600 of the parent item every month for the next three months.
The item master for the child item has a procurement method set to Buy and its order interval set to Six Monthly as i described above.
When looking at the Recomendations however, the suggested Purchase Orders are every month. If the order interval for the child item is six months then I would expect these three orders to be combined into one.
I have uploaded screen shots to my flickr account to better explain the problem, please find them at:

AM getting a LSMW error while uploading to forcasting view for total consumption value.
LSMW log shows Enter MRP type.

Hi Amresh,
You might have missed to enter mandatory field MRP type in Flat File. Better make a column for MRP type for all materials and proceed.

Order of delivery schedule line counter at schedule agreements from MRP run

Currently we are using schedule agreements for our long term external suppliers, but we are facing a problem with the order of new delivery schedule lines created during MRP run.
Because of master data settings like, lot size, rounding value, plan delivery time and planning time fence to set as firm new requirements, multiple schedule lines are created with no order for schedule line counter.
Does anyone is aware of a BADI, user exit or customizing control to have this schedule line counter in order?
Thank you
