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

MRP Type and procurement type tabs in mmd

Hello Experts,
I was trying to check the MRP Type for a material master.
In MM01, I could not locate such a tab. I think I have seen it before.
I have entered most of the selection info like Material code etc.
Or is it that MRP type is not visible from material master?
What if its blank?
I check the MARC table for the material code and the MRP type is blank.
Also, in which tab can I maintain the procurement type? Could not find such a field in mmd.
Have a nice day everyone.
regards
Bass

Hi,
MRP type and Procurement type are under tab MRP 1 & MRP 2 respectively in material master.
Check MRP1/2/3/4 tabs all information you need is there.

What is message type, basic type and logical message?

I have a question with EDI.
What is message type? what is basic type? what is logical message?
I am a bit confused. I appreciate your links that you may provide, but even if you can brief me in a few sentences, that will be great.
Thank you,
Krishen

A Message type indicates the type of business document that you are trying to transmit or receive.
A BASIC type is the IDOC type, which is the actual document that is being exchanged. A message type can be associated with different IDOC types and depending on the requirement you can choose the appropriate one.
A logical message is nothing but the message type.

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.

Managing planning time fence ( P1 MRP type ) and firm zone in ME32L

Hello,
I want to know if there is or are some documents to know how to manage planning time fence in MM02 and firm zone in ME32L ?
For me, in ME32L the firm zone is the firmed quantities sent to suppliers but not firmed for MRP so how to manage this easily ?
Thanks.
Romeo.

Dear,
Firm ZOne in SA, says that that much qty will be procured from that vendor with in that date specified, if not taken the production cost and cost related to that will be paid.
Now the planing time fence, is the time with in which no change is allowed. Hence if there is any new requirement to that RM, then it will be pushed to outside the time fence.
Hence if there is a schedule line which is already there and requirement is coved with in that, then your requirement is met, if not system will create a new schedule line in the trade off zone/planning zone.
I hope you got the point.

MRP Type V1, VB, or PD.

I am loking to maintain MM02 MRP Type and maintain re-order point at 0.
MRP Type V1 & VB are not allowing me to enter 0 as a re-order point value.
I am in a simple distribution environment where finished goods are purchased and issued with no sales or production requirements.
I would like to run MRP and generate Purchase Requisitions for items with re-order points.
I am also looking to maintain the Material Master for items that are not required to have re-order points but may need to be ordered in future.
The current MRP Type is: V1 with Lot Size: HB.
Therefore I am unable to change Re-Order point to 0.
What is the best setting for this enviroment to maintaint the Material Master and have re-order point of 0?
Thank you,
Tim

Hi Tim!
Your question is related to MRP module of ERP, however, this space is dedicated to SAP ME and MII solutions. Thus you'd rather re-post the question to a proper forum - this might help you find the right one.

MRP type "VB" components generated dependent reqt. after MRP by sales order

Good morning to all SAP gurus
        I hav scenario for mech. industry where we r going to implement MRP run , having FERT which is MTO scenario and " PD" MRP type.and its BOM components having MRP type "VB" with no strategy type. At MRP run after creating sales order system generated purchase requisition for components(ROH) depends on sales order requirements along with reorder point PR. So please help me system shouldn't generate PR depends on sales order requirements should create as per reorder point PR only.
       EX.   To manu. 1 nos of FERT (PD) required 1 nos of ROH (VB) . we r creating sales order of 10 nos. , reorder pt is 11 and
stock is 15. after mrp run system generated PR for 10 nos which is dependent for sales order.
       Pls elaborate regarding above scenario. Thanks in advance.
Regards
siva

Dear
Practically speakig , system should generate special stock PR as you are dealing with MTO sales order and MRP should plan the depedent requirement accordingly based on the MRP4 -Indiviaul and Collective Indicator -1 .
But , if you do not want to consider it as special stock , then you need to assing MRP4 Individual and Collective Indicator -2 and run MRP MD02-2,1,1,3,3 .
In you case , you have already stock 15 pc and ROP -10 , so system will not genreate any PR because , it will fullfill the requurement ( 10 PC FERT -10 ROH) .Once the stock fall behind 10 , then it will trigger PR .
Hope this is clear

Related to condition types and access sequence

Dear all,
i want to know abt one scenario, m using a pricing procedure with my service PO: ZVSTOT, in this Procedure, 12 condition types are there, during searching i found tat 3- 4 condition are are using different different access sequence, so i want to know tat in what procedure, we do it, what is use of it.?
plz reply me.

Hi Nisha,
Prcing procedure configured in your service PO PO: ZVSTOT, Based on this pricing procedure system adopted the condition type in PO.
Please go through this below link to better understanding the MM-Pricing procedure
http://it.toolbox.com/wiki/index.php/Pricing_Determination_Process_-_MM
http://www.sap-img.com/materials/steps-for-mm-pricing-procedures.htm
CONDITIONS OR PRICING PROCEDURE or PRICE DETERMINATION PROCESS
We deal with the Pricing Procedure for vendors.
PB00 Gross Price (info record, contract, scheduled Agreement)
PBXX Gross Price (PO)
FRA1 Freight
RA00 Discount on net
RA01 Discount on Gross
ZA00 Surcharge on net
SKT0 Surcharge / discount
ZPB0 Rebates
MWVS Input Tax
MWAS Output Tax
BASB Base Amount
RM0000 Calculation Schema or Pricing Procedure
(PB00 & PBXX)
RM0002 Calculation Schema or Pricing Procedure
(PB00)
PB00 --> AB00
Copy the Standard one and create new one (ours)
RM0000 contains all the condition types
Pricing Procedure (PP)
We define the pricing procedure to define condition supplement for the material price. The condition supplement specifies the discount, surcharge, freight etc that we want a system every time to access material price condition records.
The total value of the material is calculated or based on all addition and subtraction i.e. discounts, surcharge, tax freight etc
Condition Table
It is a table, which defines the structure of condition record key.
Condition Record
It is a data record used to store conditions or condition supplements, i.e. condition like, discount, freight, and surcharge, Tax etc.
Condition Type
It is used for different functions. In Pricing the condition types leads you to differentiate different types of discounts, in output determination, batch determination, difference between two output types, such as delivery note or order confirmation, between different strategy types
Access Sequence
It specifies the order in which system searches or access the condition records from condition table
Difference between PB00 & PBXX
1. Condition maintained in PB00 is time dependent whereas PBXX is time independent.
2. Condition type PB00 u2013 used for IR, RFQ, Contract, Schedule Agreement
Condition type PBXX u2013 used for PO.
Calculation Schema
The main function of calculation schema is to provide framework of steps for the price determination process to specify the discounts, surcharge, freight rebate etc.
It also determines the sequence of conditions that are to be followed and in which sequence.
Schema Group Vendor
The main function of it is to identify or to pick the right process and conditions for a particular vendor.
Schema Group Purchasing Organization
Key that determines which calculation schema (pricing procedure) is to be used in purchasing documents assigned to the relevant purchasing organization.
Schema Group
It allows to group together the purchasing organizations, which uses the same calculation schema.
Steps: -
1. Create Access sequence
2. Create condition types
3. Create pricing procedure or calculation schema
4. Link pricing procedure & access sequence to condition type
5. Create schema group for vendor
6. Create schema group for purchase organization
7. Assign schema group vendor-to-vendor master record in purchasing data view
8. Assign schema group purchase organization to our purchase organization
9. In inforecord purchase organization data enter condition types and pricing or calculation procedure
CUSTOMIZE SETTINGS: -
SPRO > IMG>MM>PUR>Conditions -->Define price determination Process
1. Define access sequence
2. Define Condition type
3. Define cal. Schema
4. Define schema group
o Schema group vendor
o Schema group purchasing group
5. Assignment of schema group to PUR org
6. Define schema determination à determine cal schema for standard PO.
With Thanks,
Thiru

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)

Requirement type and Schedule line category

Hi SD Gurus,
1) Please let us know, where to see the Requirement Type (Control filed of Availability check and TOR) in the sales order. I dont remember now and I knew that we can change the Requirement type in sales order, while creating the same.
2) In the Intra-stock transport order (stock transfer between Plants with in a company code), how the schedule line category NN is getting determined and what is the purpose of this schedule line category?
Please advice on both the doubts...
Regards,
Manivannan R

HI,
Schedule line category determined in the combination of MRP type and ITEM Category(MRP will be maintainedin the material master and the item category will be determined in the combination of Sales doc typitem ct grpusagehlev.,itmcatdef.,itmcat+man.,itmcat) and the use of this item category NN is stock will be transfer frm sloc to sloc within a plant and for more info check tcode OMJJ take help of MM consultant.

MRP Type P1 and late firm schedule lines

Hello All,
     We are using MRP Type P1 which firms our schedule agreement schedule lines within the planning time fence (as desired). However, sometimes the supplier is late on delivery and the firm schedule line goes into the past.
     Is it possible to have MRP move the firm schedule line delivery date to today instead of going into the past?
     Thank you,
     Jerry

Hi ,
Bring process forward (reschedule in)
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .
Regards,
Jayavimal

Automatic reorder point and safety stock caluclation- MRP type:V2

Hi,
I want the system to calculate reorder point and safety stock. To simulate this i created one material with
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as 100 nos in material master.
04.2009     100
03.2009     100
02.2009     100
01.2009     100
12.2008     100
11.2008     100
10.2008     100
09.2008     100
08.2008     100
07.2008     100
06.2008     100
05.2008      100
Then I went to MP30 and executed the forcase.When I checkd the material master the system has calculated the reorder point as 14 nos. But there is no value updated in safety stock field.
Now I have two questions.
1) How the system has arrived the reorder point value as 14 nos.
2) Why there is no safety stock updated in material master.
Could u please clarify this.
Thanks and Regards
Purushothaman

Hi,
This is further to my preivous mail. I have changed the consumption values and now i am getting the safety stock.
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as.
04.2009     100
03.2009     80
02.2009     110
01.2009     85
12.2008     90
11.2008     95
10.2008     125
09.2008     90
08.2008     90
07.2008     92
06.2008     101
05.2008     100
After executing the forecase the sytem has calculated the below parameter.
Basic value:95.759
MAD:11.448
Safety stock:10.252
Reorder point:23.658.
Can anyone explain me how these calculation arrived.
Thanks and regards

Sales Order is not consider for MRP in MRP Type PD and Strategy 40

Sales Order quantity is not consider for net requirement calculating in MRP.
My MRP Type is PD and Strategy 40.
Also in MD04 Sales order is not appearing.

Dear,
Requirements to MD04 will flow based on the settings you maintain in OVZ9 for the combination of "Availability Check" and "Checking Rule". Here whatever fields you choose under the tab "In/outward movements", that will be considered.
It may be because of Requirement type Missing at schedule line category level . In MD04 requirement are pass on Either Individually or collectively . In Case of Individual each schedule line create one entry in MD04 ( Stock Requirement list)
So check the materail master for checking group is maintain or not?
Please refer this thread also,
Re: Sale order not reflecting in MD04
After that run MRP again and check the result.

Difference between MRP Type PD and VB

Hi All,
I have a scenario, in which i have some doubts which i have mentioned below.
1. MRP Type 'PD' with maintaining Safety stock for the materials which have longer lead time. Will the safety stock which exists will cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays.
2. MRP Type 'VB' with maintaining Safety stock, reorder point, Maximum stock level for the materials which have longer lead time. Here the safety stock which exists will cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays.
3. MRP Type 'ND' with maintaining Safety stock.
Of all these 3 MRP Types, what will be the outcome after doing the MRP Run? Should I go for separate MRP run for VB type materials?
Please give the solution.
Regards,
Ram

Hi Ram,
PD: this requirement type considers teh requirements in terms of Sales orders,PIRs stock transfer requireements etc for the material and then does the net requirement calculation and creates procurement proposals accordingly. it also considers safety stock while doint the net requiremetn calculation.
VB: generally used for items with a fairly consistent consumption pattern. here the requirement depends on the safety stock and the current stock. if the current stock goes below the reorder point, then only a requirement is generated. besides the safety stock it does not consider any othe requirement.
ND; these items are not planned. so no effect of MRP run
normally for the VB type materials, a background job is scheduled that does the MRP run at predefined schedules.
even for items with PD, the MRP job can be scheduled at predefined intervals according to the MRP controllers or some other parameters like production schedulers, MRP group etc.
please let me know if u need more details
