MRP type configuration :MRP procedure

HI gurus ,
when I am doing the requirement planning for material with MRP type RF (with MRP procedure W) the material can not be planned by MD03,but only by WRP1 ,after I change the MRP type to VV (with MRP procedure S) ,it works .
My question is : how to make clear the difference behind the different transaction ,is it based on the different MRP procedure in the MRP type configuration or something else ? And what else MRP type can be planned with MD03?
Thanks in advance
Ryan .

Hi,
As far as, I understand, there is not linkage of MRP Type and Planning Transactions. Planning Transactions have their own purpose.
MD01 - MRP Run ast Plant level based on Scope of Check
MD02 - MRP - Single-item, Multi-level (This will explode the BOM of material entered for planning and plan all the componenets)
MD03 - MRP-Individual Planning-Single Level (This will not explode the BOM of material entered and plan only the entered material)

Issue;Specify a valid MRP procedure

Hi Guru:
When I am doing extension the material to the new plant which I configured before,and I encountered the error message "specify a valide MRP procedure" while maintaining the MRP setting specified to the new plant,please help to solve.

Hi Allen,
The message is correct...
The message comes because the MRP settings are to be maintained at the level...
So when you extend the material for a new plant...and at the same time when you maintain the MRP data or MRP view...system will ask you to maintain all the MRP data that is required...
So, please maintain you MRP data again at this level..
You can also take help of MRP profiles..to copy the data into MMR...

Specify a valid MRP procedure

hi all,
While i am doing MRP/CBP, at MMR in MRP1
for MRP procedure i gave
MRP type = VB
for Lot size data
Lot size = HB
but system is showing a error "specify a valid mrp procedure"
Hw can i solve this issue

Madhu,
I have never seen that message. Have you ever successfully run MRP in this plant using any MRP type? (MRP will not execute without first being configured)
MRP procedure is defined as part of the MRP type (OMDQ). I tried the combination of VB/HB on two different systems, with no problems. Is it possible that someone has altered either the MRP type VB (which should have MRP procedure 'B'), or the Lot size HB, on your system?

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 .

MRP types and procedures

Hi people!
I am new to this forum.
We are implementing SAP in our company now and I am responsible mainly for MRP.
I need to determine main features of SAP MRP types.
Unfortunately I found my SAP manuals and SAP help too vague.
I want to create a kind of table which would unify all existing information.
Like for example:
Planning type can be.... (CBP, independent requirement etc) -
In this planning type there can be the following MRP procedure (reorder planning with or without external requirements etc) ...
- In these MRP procedures how can be defined future requirements? (forecasts, trends, seasonal etc.) - How is Safety stock defined - Waht is the Lot size?
etc etc
Guys, if you know where I can find such a table in web please let me know so that I don't waste time.

Goto the site..u will find all the help

MRP To Generate SCHEDULE LINES for Scheduling Agreement

Hi
I have followed the below steps but still the Schedule lines is not generated for scheduling agreement.
1Maintain MRP views 1,2,3,4 for the material in material mste.(MM01)
2. Maintain Purchase Info Record for the vendor plant & material combination.(ME11)
3. Create Scheduling agreement using ME31L
4. Maintain source list for the material & the scheduling agreement # and Line item set the MRP relevant indicator 2 (Necessary ?) ME01
During Run MRP for the material.the below details entered///
Processing key NETCH Net Change in Total Horizon
Create purchase req. 1 Purchase requisitions in opening period
Schedule lines 3 Schedule lines
Create MRP list 1 MRP list
Planning mode 1 Determination of Basic Dates for Planned
Run MDBT or MD02 but still doesn't create the schedule lines......Anything else missing.
MRP1:
MRP Procedure: PD
MRP Group: 0000 (External Procurement only)
Lot Size: EX (Lot For Lot)
MRP2:
Procurement Type: F
Sched Margin Key: 000
MRP3:
Avilablity chec: 02 (Individual requirement)
MRP: 4
Nil

Raj,
Source List a Mandatory for Scheduling Agreement, if you want to create automatic Scheduling line.
Plz use (2) in MRP RELEVENT tab in ME01 (Source List).
rest of the thing is ok, make sure a material master(MRP 2 VIEW) in that view you have to give a planed delivery days. it is must.
HOPE IT WILL WORK

Discontinued parts with MRP type VB

We have scenario as below :
1.       We have material A with stock 100, open PO 50.
2.       The material A is now planned to be phased out by replacing it with a new material B
3.       Material A had MRP type VB now we will change it to ND
4.       Material B will have MRP type VB
5.       So when we run MRP for materil B it should consider stock of material A & Open PO of Material A for calculation during the MRP run and the new requirement calculation should be
Example :
Material B is set up with RO point 100 and max stock of 150
So when we run MRP for Material B even though stock for material B is zero it should not generate any new requirement as stock & open PO of material A exists.

Hello
Please take a look on the following note, which explains the general restrictions of the discontinuation process:
43636 - Discontinued parts
The note provides the following explanation regarding the MRP type:
The material is planned using an MRP procedure, for example, MRP type PD.
Therefore, since you are using MRP type VB, which uses a reorder point procedure, the discontinuation will not happen and your system is working as designed.

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).

Contract - MRP Issue

Hi
Contract exist for a Raw Material,Enenthough for the demand MRP generates Purchase Requisition for that Material.
If i assign Source of supply it will automatically pick the
contract. If i create PO with ref to PR it will not affect to
Contact.
Basically I want to know the Procurment and MRP Procedure
if there is a contract exist for the material.
Thanx in advance,
RRS.

what u are doing is correct
please check have mentioned the contract no. in the sourcce list in front of your vendor and also give the mrp indicator for that vendor

MRP Purchase requisition not generating to Max stock

Hello Gurus,
We have implemented consumption based planning. Purhcase requisitions are automatically created based on the stock reaching reorder point.
MRP type used is VB
Lot Size   used is HB
Min lot size       is 1
Max lot size     is   11
Rounding value is 1
MRP is run using program RMMRP000 setup as a batch job.
But the problem is purchase requisition is generated only for 1 quantity. There is no stock available in the plant and there are no open purchase requisitions or purchase orders for the item.
So please let me know what is missing that the lot size HB is not generating PR for max stock.
Thanks,
Narayan

Yesterday you wrote Max lot size     is   11 today Max lot size is        0
What shall I believe now?
The calculation of quantity in reorder point planning is described in
Reorder Point Planning Procedure - MRP Procedures - SAP Library

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...

In mrp

what is the diffs b/w safety stock, reorder point, backflush

Hi Bakyaraj,
Safety stock: This is the buffer stock which defining in Material master , if you are stock is falls below safety stock then system give mesg or error depends on the settings in SPRO , u can see this while converting planned order to production order.
Reorder point: This one of the MRP procedure like MRP, MPS and consumption based planning eg RO point.
This u can define in MM01 of MRP view .
If the plant stcok and firmed receipt falls below RO pont then system calculte the shortage quantity automatically with the help of Lot size procurment - generally it is replenishment up to maximum level and Fixed lot size.
For this u have to give RO point u have to give Safety stock ,Average consumption
Replenishment lead time if ur using this lot size , with this u also define 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 it dependa wheather u r using manual RO point or Automatic RO point.
Backflush:This function is auomatic posting of goods without doing MB31 with 101and MB1B with 261.
This settings u can do in MM01 , work center and routing.
Apart from this there is one more setings in OPl8 i.e order type dependent parameter .
In REM process there is agin backflush terminology for posting order / production these are assebbly backflush BOTh GI and GR done.
Component backflush - only GI done
Activity backflush - only activity posted no GI and GR
Hope u will clear , If so then reward and close this thred

Without MRP, with BOM explosion

Hi,
I'm new to SAP and learning SAP SCM. I would like someone to brief me on what the following lines imply, especially 'without MRP, with BOM explosion'.
"dependent requirements must be determined for materials that are planned in SAP ECC. So, you assign the MRP type X0 with MRP procedure X (without MRP, with BOM explosion) to the materials planned in SAP SCM."
Thanks,
Krish

Hi,
Without MRP , with BOM explosion - means the dependent requiremens are created for this materials from APO.
The MRP will not run in APO. Only the dependent requirements will be created from APO. The MRP for this materials will be executed the ECC or R/3 system to create planned order anb purchase requisitions.
Thanks and regards

Stock Transport from plant to MRP Area

I have been looking for explanation on how to handle replenishment of MRP area storage location stocks within a plant. We use Special procurement types but they are set up on for plants, not MRP areas. Can anyone explain how this works and the configuration to make it work? Were setting up a warehouse as an MRP area and need to replenish its stocks with MRP.

Aren't your questions answered in SAP online help?
Integration
The process is the same as for Storage Location MRP. In contrast to the storage location MRP, you can use all MRP procedures and are not limited to the reorder point planning procedure.
Prerequisites
In Customizing for MRP, you have created the special procurement key for Stock transfer from plant to MRP area for the plant in which the MRP area is located. You have defined the following parameters:
- Procurement type: F for External procurement
- Special procurement: U for Stock transfer
- Plant: Number of plant, to which the MRP area belongs.
In the material master, you have created the MRP area segment and assigned the special procurement key Stock transfer from plant to MRP area.
Features
During MRP, the system generates a stock transfer reservation for the material in the MRP area and a material reservation in the plant MRP area.
The external procurement storage location that you have entered in the MRP area segment of the material master is used as the receiving storage location. If you have not maintained this field, the system uses the receiving storage location that you entered for the MRP area in Customizing.
The actual procurement is processed by the plant. With stock transfer to the MRP area, you carry out the transfer posting for the material with reference to the reservation.
Standard procurement key 45 is for that purpose: plant: 1000 (V460A-WERKS), procurement key F; special procurement: U; plant: 1000 (V460A-WRK02).
So, in both fields you have to write the same plant as it is clearly written in SAP onilne help.
As SAP help says: a Stock transfer reservation is created. Using MIGO (A08; R09) you can post the goods movement by mvt 311 with reference to the Stock transfer reservation (MB1A is also good).
Why don't you test in in your sandbox system and you will see how it works.
(If you want to use STO (purchasing document type UB) in this process you have to go trough OSS note 599915)
