MRP Type VV - Forecast Based Planning

Hi all,
My company would like to look at MRP Type "VV" - Forecast Based Planning (under Consumption-based Planning) for FG production materials.    I've read quite a bit about the concept and some based set up to how it works.   We would like to base Planned Orders > Production Orders based on this type of forecast planning.   It seem that SAP advises this kind of plannig for Raw Materials but not FG.   Anyway, what I really need to know are the specifics of how you set up the master data (in the Material Master) to properly execute this type of MRP: like....
MRP Type: VV
Lot Size: EX
Period Ind: W
Availability Check: 02
Forecast Period:   12
Periods per Season: 12
Historical periods: 60
other fields I'm not sure......
RP Profile: ??
Forecat Profile: ??
what else......?
Also, what is the recommended approach to convert this forecast plan into Planned requirements to be converted to Production Orders?
I appreciate any further information I can get on MRP Type "VV" and how it works.   I appreciate your input!

Thanks for the info nudratmaab.    Can you provide further data on what to expect given this forecast.....say I pick MVGA (Moving Average Forecast)? So I enter some consumption (say last 12 months) and run forecast (MP38).    The MD04 shows the average requirement per "W" bucket:
02/23/2012     ForReq     W 08/2012                16-
02/27/2012     ForReq     W 09/2012               116-
03/05/2012     ForReq     W 10/2012               116-
03/12/2012     ForReq     W 11/2012               116-
03/19/2012     ForReq     W 12/2012               116-
03/26/2012     ForReq     W 13/2012               116-
04/02/2012     ForReq     W 14/2012               116-
04/09/2012     ForReq     W 15/2012               116-
04/16/2012     ForReq     W 16/2012               116-
04/23/2012     ForReq     W 17/2012               116-
04/30/2012     ForReq     W 18/2012               116-
05/07/2012     ForReq     W 19/2012               116-
The next part is where it is a little foggy for me.   For "VV" do I run WRP1 (Replenishment) or do I run MD02/ 03 (MRP) and then what is the ForReq converted to (or does it even convert)?   I'm looking to implement this for Production Planning Requirements for Finished Produced products (I need them to convert to PldOrd (Planned Orders) to be converted to PrdOrd (Production Orders) by production scheduler.
The second part of this is the Raw Material (BOM component) associated with these Finished Goods. THese BOM components are set up as MRP Type "PD" and Lot size "EX" and I was hoping that the FG MRP run would also do BOM explosion and drive requirements for the Raw Material as well.....I'm not seeing that.
I need professional / expert to tell me how this works:    So MRP Type "VV" & Lot Size "EX" for the Finished Goods.......and MRP TYpe "PD" & Lot Size "EX" for the Raw Material (BOM Component).....
THanks again!!

Forecasting Based Planning with Dynamic Safety stock Calculation?

Hi Guys:
Based on the client requirement we are going with forecast based planning i.e based on Sales historical data , rather then buyer determining how much amount of safety stock need to be maintained ,
Can system calculate/propose safety stock based on lead time and service levels set for that particular material?.
how to load historical sales data into the system before go Live , so when they run MRP Run ( using forecast based Planning ) -> Planning orders>PO are triggered? or is there any alternative ?
Thanks
Sweth.

Hi.
Range of coverage profile in material master MRP2 view
The range of coverage profile contains the parameters for calculating the dynamic safety stock. This is a statistical calculation on the basis of average daily requirements.
Use
The dynamic safety stock is calculated depending on the requirements within a specified period and the range of coverage.
Dependencies
The range of coverage profiles (period length for calculating the average consumption, range of coverage, and so on) are maintained in Customizing in the MRP screen.
SPRO>MM>CBP>MRP CALCULATION>Define rage of coverage profile
or
Production>MRP>MRP Calculation>Define rage of coverage profile

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 .

Forecast Based Planning

Hi Gurus,
In which type of material forecast based planning (VV) is used in business process?
Forecast requirement are obtained by forecast run of these material.
Further you get the planned orders only when you run MRP on plant level or on that material. Planned orders not generated on its parent material?
Pl through light on this.
Srini

hi
forecast based planning is a type of consumption based planning . if u know the historical consumption of ur materials then u can plan with mrp type VV , u need to maintain the consumption data in forecast view of material master. Run ur forecast in MP38 or MPBT and then run mrp based on ur for req,.
MRP run will not consider PIR or sales order .

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.

Which table can we see consumption and forecast values in forecast based planning

Dear SAP Gurus,
I am working on implementing forecast based planning for Spare parts for my client. They have one Main Plant which do purchase of Spare Parts and through Stock transfers moved to 60+ Plants from where Spares are being sold.
Now I am carrying out SAP trial runs for a set of 160+ materials with various models and want to compare with their existing methodology of requirement calculation.
I want to compile Consumption and Forecast data month wise for these trial materials (160+ materials in 60 Plants) . One way I thought is to go individual Material Master and looks for values in Forecast view. However it is tedious and time consuming.
The table name shows RMCP2 and RM03M for forecast and Cons values, but I could not find the table.
Hence I want to know which table if I can view I can get the consumption and forecast data calculated for quick copying and compilation.
Thanks and Regards,
R.Velmurugan.

Dear Mariano,
Thanks for your valuable inputs.
Like I could able to get the consumption values for materials using table MVER and fields GSV01,GSV02 etc.,
What field I need refer in table PROP for getting forecast values.
As such I could not see any column where in data are similar to Forecast view.
Thanks and Regards,
R.Velmurugan.

Forecasting Based planning, consider incoming Sales orders, Consume PIR's

Hello Guys:
I am in real Problem about this one: I am implementing forecast-based MRP for our client which is a trading company: buys, keeps in storage and sells goods (R/3 ECC 6). We are using material forecast on a monthly period, and run MRP on a weekly period since POs are to be created weekly (therefore we also use the "Splitting indicator" to split monthly forecast values to weekly requirements)
The way MRP calculates future stocks in this situation (MRP type VV) is like this:
Current stock
+ Open POs to arrive
- Forecast Requirement
= Future stock
The problem with that one is that if there is an SD order or delivery in the future, SAP does not count in that one as well. It is a real problem, just imagine that in two weeks we have a forecast of 10 pieces of a material. SAP will propose Preqs based on this 10 piece consumption, even if we have an SD sales order for that week on 30 pieces. (by the way the SD order is in the list of MD05 but SAP does not count in that one for future stock reductions).
If I modify the MRP type in customizing OMDQ, I can make SAP to count in real consumptions (sales orders) in the future stocks: I set "MRP procedure" to PD (MRP) or "R1" (Time-phased materials planning). In this case MRP calculates like this:
Current stock
+ Open POs to arrive
- Forecast Requirement
- Real future requirements (sales orders)
= Future stock
So in this case SAP will recommend double quantities to purchase: once for the forecast reqs and on the other hand for the real sales orders.
It is a trap, SAP should reduce the forecast requirements with the real requirements. The really bad news is that there is a switch for this in OMDQ for the MRP types called "Reduce forecast" but it is not working: I have tried all the combinations of codes in the frame "Use forecast for MRP" but it can only decrease req for the current month and only on a timely basis code "2" for MRP procedure "PD" or "R1".
Thanks for Help.
Sweth123

Hi Mario:
I am using MRP type PD , Running the forecast using MP30 which generate the forecast requirement.
I go to MD61 , I Slected Material Forecast option and Copied the forecast requirements as planned independent requirement,
AFter that when i run MD02 and go to MD04 Screen.
System Displays MRP Element: UnPlrq----Forecast quantity --1000
MRP Element VSF for Planned Independent requirement -1000.
Based upon historical consumption data , if there ia requirement of 1000pc , system is proposing 2000 pcs to buy.
Is there any config setting i need to change so that system won't double the requirement quanitities?
Please clarify
Sweth.

MRP TYPE IN REORDER-POINT PLANNING

Hi
I would like to know the difference between the V2 and VM MRP type in the individual Material Master record.
Because, for me, both are for Automatic Reorder-Point Planning and I don't know which I have to choose.
Thanks in advance.
Best regards.

Forecast program is used to calculate reorder point.
check this document
[http://help.sap.com/erp2005_ehp_03/helpdata/EN/f4/7d257044af11d182b40000e829fbfe/content.htm]
Even when you the calculation is based on past consumptions, in the forecast view you maintain parameters for tendency (seasonal, etc), how many periods are to be taken into consideration and you may also manually adjust consumption quantities. You may refer consumptions to other materials (i.e. when you have a new material code, replacing an old one, you can use this old one historical consumption data to calculate reorder point).
Hope this helps

VV Mrp type

With MRP type VV (forecast based planning), after i execute the forecast program, i can see the forecast req. in the MD04 screen.
When i run the MRP, the net requirements calculation is not considering new sales orders. It is strictly limiting to the forecast requirements that is...it is generating Purchase req. only to cover the safety stock and forecast requirement for the month and not considering new sales orders?
is there a specific customizing change i need to do to make this work?
Thanks
SD

Dear,
This is not possible because MRP VV planning works based on the consumption (withdrawal) of components not on the requirements.
So there will be requirements creation for the part MRP type VV ( No requirements will be passed and no dependent requirements will be created).
So conclusion is requirements will not be passed..planning will be based on the consumptions of this materials.

MRP type VB

Dear All,
Please someone suggest me why should we use VB and to maintain safety stock for materials which is having longer lead time?
Thanks,
Rinky

Hi,
VB is the MRP TYPE for consumption based planning. Please go through the below for understanding the CBP and safety stock.
In consumption-based planning, the following MRP procedures are available:
Reorder point procedure
Forecast-based planning
Time-phased materials planning
Reorder Point Planning
Use
In reorder point planning, procurement is triggered when the sum of plant stock and firmed receipts falls below the reorder point.
Features
The reorder point should cover the average material requirements expected during the replenishment lead time.
The safety stock exists to cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays. Therefore, the safety stock is included in the reorder level.
The following values are important for defining the reorder point:
Safety stock
Average consumption
Replenishment lead time
The following values are important for defining the safety stock:
Past consumption values (historical data) or future requirements
Vendor/production delivery timelines
Service level to be achieved
Forecast error, that is, the deviation from the expected requirements
Manual Reorder Point Planning
In manual reorder point planning, you define both the reorder level and the safety stock level manually in the appropriate material master.
Automatic Reorder Point Planning
In automatic reorder point planning, both the reorder level and the safety stock level are determined by the integrated forecasting program.
The system uses past consumption data (historical data) to forecast future requirements. The system then uses these forecast values to calculate the reorder level and the safety stock level, taking the service level, which is specified by the MRP controller, and the material's replenishment lead time into account, and transfers them to the material master.
Since the forecast is carried out at regular intervals, the reorder level and the safety stock level are continually adapted to the current consumption and delivery situation. This means that a contribution is made towards keeping stock levels low.
Forecast-Based Planning
Use
Forecast-based planning is also based on material consumption. Like reorder point planning, forecast-based planning operates using historical values and forecast values and future requirements are determined via the integrated forecasting program. However, in contrast to reorder point planning, these values then form the basis of the planning run. The forecast values therefore have a direct effect in MRP as forecast requirements.
Features
The forecast, which calculates future requirements using historical data, is carried out at regular intervals. This offers the advantage that requirements, which are automatically determined, are continually adapted to suit current consumption needs. The forecast requirement is reduced by the material withdrawal so that the forecast requirement quantity that has already been produced is not included in the planning run again.
Reducing Forecast Requirements
Reducing forecast requirements by consumption
If consumption is higher than the forecast requirements in the current month, then the system also reduces future forecast requirements.
Reducing current forecast requirements by consumption
If consumption is higher than the forecast requirements in the current month, then the system does not reduce future forecast requirements.
Average reduction of the forecast requirements
The reduction of the forecast requirements is based on average daily consumption. Actual consumption data is not relevant.
The system calculates the average daily requirement first using the formula forecast requirement/number of workdays in the forecast period.
The forecast requirements are then reduced by the quantity resulting from the following formula: number of workdays worked x average daily requirements.
Period Pattern and Forecast Periods
You can specify the period pattern for the forecast (daily, weekly, monthly or per accounting period) and the number of periods to be included in the forecast individually for each material. It is possible, however, that the forecast period pattern is not specific enough for planning purposes. In this case, you can define per material that the forecast requirements should be divided according to a finer period pattern for planning. You can also define how many forecast periods are to be taken into account during requirements planning. The splitting indicator is defined in Customizing for MRP per plant and per period unit and is assigned to the material in the material master.
Time-Phased Planning
Use
If a vendor always delivers a material on a particular day of the week, it makes sense to plan this material according to the same cycle, in which it is delivered.
Features
Materials that are planned using the time-phased planning technique are provided with an MRP date in the planning file. This date is set when creating a material master and is re-set after each planning run. It represents the date on which the material is to be planned again and is calculated on the basis of the planning cycle entered in the material master.
The net change planning indicator and the net change planning horizon indicator are irrelevant for materials planned using the time-phased planning procedure. The system does not therefore set these if changes are made in the planning run.
If you want to plan a material earlier than the specified MRP date, you can enter an MRP date during the planning run. For example, if the planning run is set for Monday, you can bring it forward to Saturday instead.
If you use the SAP Retail System, the system proposes the planning cycle from the vendor sub-range when you create a material master record. The vendor sub-range contains all the goods of a particular vendor that, from a logistical view, can be planned similarly.
Time-phased planning can be executed using consumption-based planning or MRP:
If you want to carry out time-phased planning using consumption-based planning techniques, the requirements have to be created using the material forecast. If you use consumption-based planning, only the forecast requirements are included in the net requirements calculation. For reducing the forecast requirements, you can choose the same settings in Customizing as used for forecast-based planning.
If you want to carry out time-phased planning using MRP, all the requirements that are relevant to MRP are included in the net requirements calculation. For this purpose, the indicator Time-phased with requirements must have been selected in the MRP type. The forecast requirements can also be taken into account in this process.
Safety Stock Calculation
The safety stock depends on the service level that you specified in the MRP II view of the material master record and on the accuracy of the forecast. The more accurate the forecast, the smaller your safety stock can be.
The following figure shows that, without safety stock, customer demand can be satisfied by 50%. It also shows that it is almost impossible to satisfy customer demand 100% of the time. Factor R describes the relationship between forecast accuracy and service level (SL).
If replenishment lead time is greater than the forecast period by factor W, then the mean absolute deviation (MAD) is recalculated for this period (formula 17). The MAD is a parameter of forecast accuracy. Otherwise, see formula 18.
Safety Stock (SS) Formulas
If the material is produced in-house, the delivery time is: opening period + in-house production time + goods receipt processing time. It is expressed in workdays. The forecast period is taken from the material master record and is also expressed in workdays.
If the material is procured externally, the delivery time is: goods receipt processing time + planned delivery time + goods receipt processing time. It is expressed in calendar days. The forecast period is taken from the material master record and is also expressed in calendar days.
The safety stock calculation may lead to rounding effects.
Minimum Safety Stock
You can specify a minimum safety stock. If the result of the safety stock calculation is lower than this limit, the safety stock is then automatically set to this minimum value. You enter the minimum safety stock in the material master record (the MRP 2 screen).

Best MRP type and strategy to run MRP for component using PIR and forecast

Hi Experts,
I want to run MRP for Component parts. I need to run MRP based on Planned independent requirements and Forecast Data.
Which is the best suited MRP type and strategy.
Please help to share bestpractices if any. thank you.
Rayudu

Hi,
is the components you are talking are Semi finished materials or Raw materials and Packing materials which are procured from vendors ???....
It is not a good idea to maintain planning strategy for Components which are part of BOM...these materials are automatically planned when the header materials of these components are planned....
If these components are not part of any BOM then you can try the option of using forecast based planning.. MRP type VV and maintain the forecasting view in the material master
You can also explore the option of consumption based planning like manual or automatic reorder point planning...
Thanks
Kumar

Change the MRP run fro Reorder Point to Forecast Based.

Dear Experts
My client is a battery manufacturing company, its Semi Finished product is Make-to-Stock and Finished Product is Make-to-Order. Initially the MRP was configured as reorder based and in Material master it was set as VM (Automatic reorder point plng ). But now we need to change the MRP form reorder point to Forecast Based. The rolling forecast of the coming 3 three months is given in Planned Independent requirement (MD61) as version u201800u2019 - REQUIREMENTS PLAN.
We have changed the MRP procedure in Material Master form VM to VV Forecast-based planning of the finished product but unable to get any result means no Automatic PR is getting generated, the we have changed all the materialsu2019 MRP procedure of that Particular BOM to have the required MRP and Automatic PR raise but still no expected result is coming.
I would request you to provide your expert opinion to execute the Forecast Based MRP, what else should I do achieve the Linking between the Rolling Forecast and MRP instead of Reorder point. Should I have to make changes in Material Master (Only on finished product, In house developed/manufactured Product, Raw material etc), any configuration change in MPR and PR . Looking forward for your specialist advice.
Regards
Sony

I have provided the demand in MD61 and make stock level of the material in such a way that it should raise the PR for MRP run but it is not generating any PR. have checked that if I put value in the forecast tab of the material master manually then it is raising the PR but I need the system to pick the value form the demand that I provided in MD61. Is there any configuration related issue to get the values form the demand and generate PR accordingly. Please guide
Should I have to provide 'VV' at the first level of the Material at its master data or at each component of the BOM irrespective of
the components for Semi-Finished (In house production), Raw materials (Procure from the supplier). Please suggest...

MRP type - Forecast indicator

Hi,
my company is using a Z - MRP type which has the following settings:
MRP procedure = D - Material requirements planning
Forecast Indicator = No Forecast
Consump.ind.forecast = G - Total consumption
MRP ind. forecast = G - Total requirements
Even though we have a Forecast Indicator set to "No Forecast", materials with this MRP type are forecasted every month. We then get some issues with requirements that are required.
Does anyone know what settings we should have in order to avoid Forecasting being run on materials with the MRP type above?
Thanks for your input:-)
Br,
Lars

Dear,
Prerequisites: Transaction OMDQ
MRP type with
Forecast indicator <> ' ' (that is, for example, * for optional forecast) (PROKZ)
MRP indicator of forecast = ' ' (that is, 'Not to be included in planning') (PROOS)
If the MRP indicator = ' ', the forecast requirements should not be involved in the MRP run
However, forecast requirements are only considered if the "MRP indicator of forecast" is set in the MRP type.
Also check the OSS note 369673 .

MRP based planning

hi guys,
what is MRP based planning and why it is used?Under what conditions do we go for MRP based plannig for procurement of materials?

I will suggest you to read the SAP help on MRP first.
http://help.sap.com/erp2005_ehp_04/helpdata/EN/f4/7d3f9344af11d182b40000e829fbfe/frameset.htm
Anyway i am trying to explainn you this functionality:
The Concept Of MRP in SAP
MRP in brief :
MRP is the planning tool in SAP which will look at all aspects of a material and is highly based upon the master data of the material. MRP looks at current inventory, current requirements, open purchase req/orders and so on. So if a material is required to satisfy a sales order and there is no inventory, MRP will create a planned order if the item is to be produced in house. This planned order can then be converted to a production order by the master scheduler. If the item is to be procured, then MRP will create a purchase req which the Buyer will convert to a purchase order. This is just one scenario, the system is highly configurable and will do pretty much whatever you tell based on config and master data.
Consumption based planning
- Reorder planning
- Forecast based planning
- Time phased planning
Details of re-order planning
Our motive is to maintain optimum stock level of all the material included in the resource planning. so in this user or system sets a particular quantity of stock as reorder point . Whenever stock quantity fall below this point(reorder point) mrp comes into action and generates procurement proposals according to the settings done in implementation guide
MRP run procedure
1. Create requirement or demand in MD61
2. MRP run by MD02 for a single material
3. See the result in stock requirement list in MD04.
MRP run we can carry out by
1. MD02 - single item multi level
2 .MD03 - single item single level
3 .MD01 - Total planning
4. MD04 Check MRP
5. MD05 MRP lists
