Regarding mrp pr requirement

Dear Gurus,
we are working on MRP
Through MRP purchase requisitions are raising on date basis.
i.e. suppose in aweek raw material is required @ 100 KG.
with referance to BOM & Qty of header level it raises 5 purchase requisitions.
I require the system should raise one PR consolidating the qty of 5 PR.
so that i can assign one PR to the delivery schedule
is it possible. ?
confirm the custmising & process.
thanks in advance.
suhas inamdar.

Suhas,
What you are describing is 'Periodic Lot Sizing", which means basing the procurement proposals on a time period.
This is effected by making the appropriate changes in the Material Master of the materials you are planning. I believe that the Lot Size (MRP1 tab of Matmaster) you want is the standard SAP lot size WB, 'weekly lot size'. If you select this SAP standard lot size, no other configuration is needed.
In this case, when MRP is performing its net requirements calculation, it finds the first instance of a shortage. It then looks forward in time for all additional uncovered requirements, for one week, and then it proposes a single proposal (purchase req) that will satisfy the entire set of requirements, regardless of parent part.

MRP dependent requirements indicator

Hi,
Can anybody please let me know use of MRP dependent requirements indicator in MRP4 view?
Regards,
Samir Wadajkar

Dear,
You only use this indicator in connection with planning strategies for make-to-stock production, assembly planning. Note that the indicator Dependent requirements not relevant to MRP should only be used when, for example, planned independent requirements exist for an assembly.
EX... If you manufacture the chemical product say named ABC and you use water as component to manufacture it , and you dont want to plan the WATER quantity as it is used in bulk . So you can exclude the material water from the MRP run and only the Chemical product is planned and not the WATER.

Regarding MRP Area

Hi All,
I would like to clarify a doubt regarding MRP Area concept.
1. MRP Area at Storage Loc level:
    What's the main advantage of this? i have gone through the documentation and
    understood how to configure it, but in a real scenario how its useful?
   For example: I have finished part: A which has components B, C & D. If i assign
   the stor.loc X MRP area to B & C not D and run the MRP on A, how system
   will react?
I am not able to understand how it's beneficial in real scenario?
Can some body help me out? i understand how it's useful for MRP Area for Sub-Con coz it will plan seperately for individual sub-con's..
Thanks and looking forward for your valuable hints and answers,
Chandra

The procedure is made clearer in the following example:
Assembly A is produced on production line 1. Components B and C, which are procured externally, are necessary for the production and are withdrawn from storage location 0001.
You can represent this situation in the system as follows:
You create an MRP area of the storage location type for storage location 0001 in Customizing for MRP. You assign the MRP area to storage location 0001.
You assign this MRP area to the components B and C in the respective material master records by creating an MRP area segment. You enter storage location 0001 in the Storage loc. for EP field in the MRP area segment, as this is also to be the receiving storage location for the components.
You create a production version for production line 1 in the material master for assembly A. In this production version, you enter storage location 0001 as the issue storage location for the components.
In the planning run, the system calculates the dependent requirements for components B and C and determines the issuing storage location 0001 using the production version. This enables the assignment of the dependent requirements to the MRP area for storage location 0001. When the system determines the procurement elements for B and C, it reads the external procurement storage location and uses this as the receiving storage location. This is also storage location 0001 so the procurement elements are assigned to the MRP area for storage location 0001. You can use this procedure to selectively plan the components that you require on the production line.
If you do not work with production versions, you can also enter the issue storage location for the components in the BOM, in the work center using the supply area, or in the Issue stor. location field in the MRP data of the material master record

Questions Regarding MRP

I had a couple of questions regarding MRP. Will be glad if you could answer these:
Is it possible to remove the 'in house production time' & 'planned delivery time' from MRP?If it is possible, what will be the impact of removing the above?
Can we change the start/end date of the factory calendar, with or without removing the above?
Please answer the above.
Thank you very much.
Regards

If we keep inhouse production time and planned delivery time as zero, will this have any other impact?
Secondly, is it possible that we can manually change the start and end dates which are suggested electronically by SAP?
As I said earlier if you keep in house production time as zero system still would allow to create a material master record and based on this MRP calculates the dates required for any planned order in basic scheduling.
If you keep this as zero you order basic start and end basic date would be on same day.
It is recommended to maintain the no days required for in house produced material in MRP2 or in WS view or you need to enter the setup, tear down, processing, and inter operation times so that based on these values, the system determines the in-house production time on the basis of lot size.
Same way for Planned Delivery Time, only the difference in both of these fields are In house Production time considers the FC where as Planned delivery time considers the calendar days.
For your 2nd Question if you change the system proposed dates in any planned order based on the scheduling type start and end dates would be changes accordingly.

MRP - PEGGED REQUIREMENT REPORT

Hi Gurus
I have a question with regards to Pegged requirement report (MD04) and was told to analyse the up stream and down stream dependencies of a planned order. May i understand where and what is that down and up stream about ?

Dear Alisonhar,
Pegged Requirements
You can use the Pegged requirements function to retrace from any BOM level
1.which requirements are the source of which procurement proposals
2.which independent requirements (especially sales orders) are affected if a procurement proposal is cancelled or a date or
quantity is changed on a lower level.
Features
For the MRP element selected, you can display:
1.just the pegged requirement(s) on the highest BOM level - The system displays the requirements quantity and the input
quantity for each requirement. The input quantity is the portion of the MRP element that is required to cover the displayed
requirement. The input quantity is displayed in the base unit of measure of the material.
2.the order route; that means all the requirements and replenishment elements that lie between the pegged requirement and the
MRP element
If an MRP element contains a quantity that was not caused by a requirement from a higher level, the system displays this
quantity separately. Quantities without source arise, if more is produced than is required because of a rounding value for the
lot size or a fixed lot size or if procurement proposals have been scheduled manually.
Use MD04/MD09 to access the same.

MRP Dependent requirements - How to define

Hello.
If I set "1" in MRP Dependent requirements field the Depended Requirements are excluded, but also the Order reservations.
Can i somewhere set so that only depended requirements are excluded and not the rest?
Thanks in advance.
/Gherry Svantesson

Dear,
In the MRP dep.requirements field, you set the indicator to 1 so that dependent requirements (reservations) are not planned.
You do not set an indicator in the Cross-project field for the availability check. This means that only the individual segment (segment of the production lot) is checked during the availability check.
Thanks,

How to Run MRP with requirement Plan Number

Dear all,
I am working for the process of MRP Run .But customer requirement is that "To Run the MRP with requirement Plan Number"
If you are aware of this scenario ,please provide the solution.
Thanksin Advance

Go to MD61
Select the Radio Button Rqt Plan Number
Write the plan number eg. "test1"
now you get the next screen
Here you can enter the materials like
first line Testmat1 -qty 100 150 ....
2nd line Testmat2 -qty 150 100
like that
So the difference between MD61 with Material and Rqt Plan number is
Material means we give requirement for only one material
But for Requirment plan number , w.r.t one Rqt Plan number we can maintain requirement for multiple material
same material with same period we can maintain requitement for Different Requirement Plan number
This is reducing effort of client of data entry and for different sales Regions for the same material through "Rqt Plan No" they can differentiate the rqt
MRP run run it for PLANT or multiple plant with Scope of Planning
thanks
Pl award points if useful

No sales orders with MRP-relevant requirements were found MD04

Hello MM Enthusiast,
We are in process of EHP upgradation and I need to replicate the following error message,
No sales orders with MRP-relevant requirements were found
Error message MF 336
Please let me know how to get the above message in S environment.
I have gone through the already discussed thread (http://scn.sap.com/thread/3460655) but couldn't able to get the message MF 336.
Based on your response I can replicate and apply the causing / resolving note given by SAP AG.
Looking forward to your valuable input to proceed further on this issue
Cheers,
Kumar S

This issue was solved using a different availability checking rule in MRP3 of the material master.
the old checking rule had a requirements summary, while the new was for individual requirements, this setting is defined in OVZ2 customizing transaction.
Hence you need to enter a checking rule in your material master which has a A as sales requirement in OVZ2.
then create 2 or more new sales orders for this item for the same delivery date.
After that you should get the error in MD04

MRP: indivisula requirements

Dear All ,
I have three Planned order for three different dates .
I need raw materials requirement individulally for all these three requirement .
I have maintained indv requirement indicator in MRP 4 view as : 1
still raw material requirement is collective , pl guide ?

HI
What is the lot size and requirement date for the raw materials. If lot size is EX and requirement date is same then system will give only one PR for all the requirement though u maintain the individual/collective indicator 1, if it is MTS. If ur going with MTO then system will give separate requirement.

MRP Net Requirements Calculation

Hi Guys:
I defined a Planning Horizon of 40 days, for Example if today is the start date Since Planning horizon is 40 days (01/30/2012).
Vendor Lead time = 2months
Purchase order to vendor with Delivery Date (12/20/2011) : 5000 Pc
Purchase order to vendor with Delivery date ( 03/04/2012): 6000Pc
Onhand Inventory = Zero
So i have Sales order for 10000 with Delivery Date ( 12/28/12) with in the Planning horizon.So when I run MRP using MD02 ,
Does the system consider Purchase orders with delivery dates that are outside planning horizon into the net requirements calculation?
thanks for the help.
Kodali

dear friend,
as far as i know the available stock is calculated as follows:
plant stock
safety stock
+
receipts (pur.orders, prod. ordersfirmed proc. proposals)
requirements quantity (say, PIRs, mat. reservations,...)
=
available stock
shortage occurs if available stock is negative, that is, the requirement quantities are greater than expected receipts and stock quantity.
so, system specifies the date of the issue (for example, customer requirement, planned independent requirement, reservation, forecast requirement) as the requirements date.
regards,

Exclude Stock Transfer from MRP Net Requirements

Hi,
Is it possible to exclude the Stock Transfer Orders from the Net Requirements generated by MRP? I want to base the requirements only from historical consumption. In my Stock/requirements list (MD04) for example, the Requisition generated by MRP increases in quantity since there are open Stock Transfers which are to be served by that plant to other plants.
Regards,
Lee

Nazrin,
Availability check configuration (OVZ9) has no impact on MRP. MRP relies on its internal rules when it is performing its net requirements calculation. You have very little control over which elements are included/excluded.
You can exclude selected storage locations from MRP planning. Stock and reservations against these storage locations will therefore also be excluded.
You can exclude a material from planning, change the material master MRP type to ND.
Your best bet, though, would be to set your PM planning process up such that these materials never create the reservation in the first place.

MRP Net Required/Available Qty

Hello Gurus ,
I am carrying out MRP at plant level .After that MD04 We are analysing the result .We are developing Z report where we need to show Net Required Quanity(-) or Avaialable Quanity .We are using MDKP/MDTB table .
1.Material Requirement Planning No xxxxxxx is not getting updated in MDTB table .I am getting MRP Table no from MDKP using Plant /Material Combination .
2.What is the SAP Table -Filed name to retrive Net Required/Available Quatity (Planned quantity on the time axis that results from comparing receipts, issues, and current warehouse stock)
Thanks and regards

Regarding MRP Run

Hi All Gurus,
Can anyone of you tell me what is the outputs of followings?
1) Suppose we put MRP Type PD ,Lot-size- EX,Min.Lot size -5, Availability check 01,then what is the o/p after MRP run?
2) we put MRP Type -ND,lot size -EX,Remaining same as above .
3) we put MRP Type -PD, Lot size-FX,Fixed Lot-100,Remaining things are same as above .

Hi Narayan,
Please find the answer as below
1.The MRP will generate Procurement proposals for the order quantity.i.e the effect of EX-lot for lot order . If the order quantity is less than 5, then also the procurement proposal will be for 5nos.i.e effect of minimum lot size.
2.Since MRP type ND no planning i.e. no requirements generated.
3.The MRP will generate procurement proposals for quantity 100. If more nos required, then many procurement proposals each for quantity 100.
Hope is is clear.
Thanks and regards

Isseu regarding MRP calculation.

Hi Gurus,
We have MTS scenario with strategy 10 ,requirement type LSF , in MD61 PIR are present from 01 /01/2011 till today , but when i check in MD04 only requirments from 01/04/2011 are taken into consideration ( for LSF requirment after 01/04 system is showing -ve qty and plan order are generated for these independent requirement ) , i want to know why PIR from 01/04/2011 are taken into account and why older PIR are not considered.
Current stock is 0 and planning time fence in 30 days and planning horizon is 100 days,, please help me understand why older demands are not taken for calculations.
Thank you,

Hi.
I assume you have run the MRP with the processing key NETPL (Net Change in Planning Horizon). And as you have define planning horizon 100 Days that's why system is taking the requirement for only 100 days. If you want to have total requirement have to consider use MRP processing key NETCH (Net Change in Total Horizon).

Vivek

Error in MRP(material requirement planning)

Hi guys,
while i was doing the process for MRP
i encountered a error in the following Transaction code MD02
when i gave the required fields it pointed out tis error
Error : Material 1575 does not exist in plant JOP1
How shall i go through this errror
pls try to give me a solution.
Regards
Jino.

First, Go to MM02 Transaction and enter your Material Number.....
Now, You can see the Select Views....
If There is No, MRP Views. or any select views..
Then Go to MM01 Transaction and Give material NO.1575 and Plant JOP1.
