MRP and MPS Run

Hi all,
I found some materials in my 'Quality Environment' which has their MRP type to 'PD' but the problem is planning run for those materials work with Transactions 'MD02' and 'MD41' as well .How is this possible ? Is there any provision in 'SPRO' to enable such ? If so what is the point in doing so ?
Regards,
Rahul

Hi Rahul,
MD02 = Single Item multi level.With use this transaction you can run MRP for single material but system will planned up to its last level of BOM.So its called as single item multi level.
But most important condition is MPS mrp types (M0/M1/M2) are not allowed this run.
While MD41 is also a Single Item multi level and can be used to run MRP up to last level of BOM.
But its advantage over MD02 is it can be used for both PD and M0 types of MRP types.
Thanks & Regards,

Difference between MRP and MPS..

Hi ALL,
I am aware that MPS planning is done for the materials which are high-valued....Main aim is to reduce costs and to increase planning stability...
Also these type of Materials can be planned using MRP...
Then why do we go for MPS Planning only...?
Thanks..
Regards,
Ameya K.

Hi Ameya,
MPS
1.In the MPS run, the materials marked MRP Type as MPS (ie. M0,M1) only will be included . The planned orders are created at the MPS Material level only.
2.The BOM is exploded for next one level down only.Further level will not be exploded,that means Dependent requirements are created for the BOM components one level down, further level will not processed.
This allows MRP controller can ensure that the MPS items are correctly planned before any MRP run takes place. This allows the planner to check and change the planning result, before any MRP run takes place for other materials.
For example,consider this business scenario, suppose one wants to do planning for finished Goods once pre week, but it is necessary to do planning for their components on daily basis.
so for this exmple, you can define Finished materials with MRP type as MPS and all the components with MRP type as MRP.
MPS run is carried out before the MRP run. So that the Planner can ensure planning result before the MRP run.
MRP.
MRP Run will plan all BOM level of Materials.
i hope i have tried to clear your doubt some what.

MRP and MPS

Hi,
what is the main difference between MRP and MPS ?
Regards

Hi,
The task of material requirements planning is to guarantee material availability. The system calculates which materials must be procured or produced at what time and in what amounts so as to provide the quantities required.
Using MPS you can carefully plan important parts or bottleneck parts in a separate planning run at the highest BOM level before the planning results have an effect on all of the production levels.
Lead time scheduling and the calculation of capacity requirements in MRP and MPS provide the basis for the creation of a master plan that corresponds to capacity planning. This way the MRP controller obtains information about possible bottlenecks and overloads. Before the master plan becomes effective and the planning results affect subordinate BOM levels, the MRP controller can make changes that affect capacity for chosen materials.
Scheduling:
Before capacity planning can take place you must create capacity requirements within lead time scheduling, that is, determine the production dates. The system only generates capacity requirements if it executes lead time scheduling using the times specified in the routing.
Scheduling in MRP and MPS determines the basic dates and the production dates for the planned order. The basic dates define the earliest and latest dates for production. The production dates use the times in the routing to determine the start and finish of production as well as of the individual operations.

How to run mrp and capacity leveling through heuritics.

Hi,
How to run mrp and capacity leveling through heuritics.
What are the setps required for production planning run this thing in the heuritics in pp/ds?
Regards,
Sunil

Sunil,
APO PP/DS doesn't have a 1-to-1 match for MRP/Cap levelling per se. There are, though, a limitless number of ways to achieve the results you want.
Start with a basic PP planning MRP - SAP_PP_002, which will should create all necessary planned orders
Then try a DS heuristic to schedule your orders according to capacity. Schedule Sequence SAP001 is a good starting point. This can be used to schedule your cap relevant work centers such that they fully load the capacity available, similar to cap levelling.

MRP, MTS, MPS and MTO in DP

Hai,
Where do we use MRP, MTS, MPS and MTO in DP? Can somebody refer me to any documentation?
Thank you.

Hi Visu,
I never imagined your question came related to a DP job requirement. While technically these are not relevant for DP, but as a DP consultant you need to be aware of the concepts which are definitely more relevant on the supply side (SNP, PPDS).
"Character Based Forecasting (CBF) deals with variant configuration or nothing but MTO scenario right?" - you can argue that CBF is a functionality for MTO scenario especially when dealing with large variety of similar products.
"Also DP-BOM works with dependent requirements generated from BOM." - DP-BOM or Forecasting with BOM is a special functionality in DP to manage demand for a product which has both independent as well as dependent requirements. Please note it is not for generating dependent requirements only. Classic example - a speaker set that can be sold separately or as part of a packaged audio system. But then this is NOT MRP because we are talking about generating the demand only.
MRP is to generate net requirements for "components" after exploding the BOM for "finished item" and netting against stock to create relevant receipt elements (Purchase Req or Planned Orders).

MPS run, planned orders were created for all levels ?

Hello PP members
I ran a small scenario
material    MRP Type     Low Level    SG           M/T Type
A      M0         000             40              FERT
B               PD              001              40             HALB
c               PD              002               10             ROH
Maintained PIRs(MD61) for material A, and ran MD41( Single Item Multi level Planning)
As material A is an MPS item, I was expecting that it should create planned orders only for material A, but in this MPS run it created planned orders for material B & C. (Looked into MD04, where I see planned orders were created
for all the levels)
As per the MPS run, it will plan only for one level of BOM (in this scenario for material A)
Any suggestions, why planned orders were created for material B & C
please clarify

Just check
System must have created a dependent requirement planned order and not the planned order for requirement you put in demand management for B and C
i.e. if you enter a demand in MD61 for B and C, run the transaction, system will not consider this requirement during MPS run. MPS run will consider the requirement if the requirement for the child is comming from parement where parent is MPS item.
Hence you need to run MRPm for B amd C if teh requirement(not dependdent requirement from A) is to be considered.
I hope you are clear

MPS Run

Hi Gurus,
During the MPS run, we see planned orders are firmed out of planning time-fence. therefore we are manually deleting these planned orders and re-running the MPS. can anyone explain why it is happeining.
Thanks,
N

Dear,
Then remove the MRP group from material master or remove the planning time fance from MRP group OPPR. And then check the result.
Sorry typing mistake no three star will be there only single star fro firming * if it come two ** means capacity planning done for planned order.
I hope it will work for you.

STO's as a output of MPS run

Guru's
Can we have output of a MPS run in the form of STO and what is the config requirements for that?

Hy,
It possible to that After running MPS Purchase Requisition is generates with reference to Deleivery plant.
Prerequisite for the same are
1) MRP type M0
2) Soecial procument key : stock transfert from alternate plant
[http://help.sap.com/saphelp_erp2005/helpdata/en/18/eeb78a938c4ec89372e972384ddd9e/content.htm]
3) After uploading Demand in delevering plant you have to first run MPS at Delevering plant.so that Purchase requistiton generates with reference to supplying plant.
4)After running MPS at delevering plant you have to run MPS at supplying plant so that demand passes from delevering plant to supplyin plant.
After completion of production cycle you can create stock transfer order with reference to that Purchase requisition.

MRP and Inventory psoting list

Hello
2 questions
when we run MRP and ask to take into account the open purchase order we have recommendation without open purchase quantity taken into account and all purchase orders open are made in 2009
Could it be because of the new year ?
Second question in item screen we right click and have for each item the option to see posting list but since 1st of January teh posting list is without stock movements and does not show 2009 movements
Do you know if we can somehow define the dates where the posting list is shown ? They want to see obviously stocks movements from 2009
Thank you for your help in advance

If your financial year ends on the 31st of December then the short cut from Item Master Data will not show the previous financial years transactions. This is standard B1 functionality and you cannot define the dates.
You can run the full Stock Postings list from the Reports menu and this will give you all transactions.
In your MRP you must make sure that the From Date includes all the purchase orders in the previous year. For example if your oldest purchase order is 01.10.09 then your start date in horizon for MRP should be 01.10.09. This will put all your purchase orders in the Past Due section but will include them in all calculations for ordering stock.

MRP and log of results

Hello Experts,
When I run MRP, I get a message like ie "10 requisitions have been created". Where can I see a list those requisitions?
I am looking for a log of what happened in the MRP run to look into the details of which documents where created and deleted and so on
rgds
GAR

Hi,
You can see the list of purchase requistions created in two ways..
In ME5A, Give the release date(date on which you ran MRP) and enter the other inputs..
It will give the desired outout.. You can give MRP controller also to narrow your search..
Another way is...
MD04. For the material which ou ran MRP , Check in MDO4..
It ll give you planned orders. Click that planned order and click the icon forpegged req in the small window.. It ll give the list of planned orders and Purchase req. under that final material..
You can then select the planned orders that came under the final material..In a similar way as above you can proceed to get the list of all the purchase reqns..
Hope the above definitely claifies..
with wishes....

What is MRP and why it is used?

hi
this question was asked in an interview can some one explain in detail for me
What is MRP and why it is used? If there are 2 Lakhs of items is it feasiable to run MRP since running of MRP for 2 lakhs of item is time consuming, if yes then how it is been done?
thanx

Dear Bashir,
1.MRP is material requirements planning which plans the required quantity of depedent material's along with the required date.
2.MRP procedure is sub divided into a normal MRP,Master Production Scheduling and Consumption Based Planning.
3.Cosnumtion BAsed planning is further sub-divided into Time Phased Planning,Reorder Point Planning and Forecast based
Planning.Reorder point planning can be automatic or Manual.
4.MRP type is differentiated using the MRP type value assigned in the MRP1 view of the material master.
5.Some of the MRP types are PD - MRP,M0,M1,M2,M3 - MAster Production Scheduling related,VB - Manual reorder point
planning,VM-Automatic reorder point planning.
6.It is possible to take the MRP for the whole plant/for a specific MRP area using the batch MRP job.
7.MDBT is the T Code for scheduling the MRP job or it can be scheduled for the program RMMRP000 using the T Code SM36
and the results can be checked using SM37.

Kanban With MRP and with External vendors

We are implementing SAP 4.7 for one of clients and here is the requirement:
They want to use Kanban with external vendors where once KANBAN is empty, it should create a schedule line for the defined scheduling agreement. Problem is , we have to exclude the material from MRP in order to work with "External Purchase Orders" or "Scheduling Agreement" replenishryment category.
They do not want to exclude the KANBAN materials from MRP but want to use KANBAN for procurement with vendors.
Is this possible?
Because when we try replenishment strategy " Working with MRP" , SAP does not create any PO or Schedule line desite of maintaining all the data. Instead, SAP allows replenishment elements created in MRP run to flow thru and create PO/ Schedule lines.
Is it possible to include the material in plant MRP and still use external procurement kanban?

Hi Vikas
Ia m not familiar with asynchronous MRP. Can you elaborate on that? What specific settings we need to make for that?
Thanks for your help.

MRP to be run for those materials that is assigned to the MRP controller

Dear Gurus,
Pl. let me know how MRP can be run for materials assigned to the MRP controller only.

Hi
You can run MRP for MRP controller using User Exit Key available in TCOde MD01.
You have to define the user exit keys and make use of the same. ( in SPRO you can do that )

MRP and Materials provided to Vendor

Can you please help with the following:
SAP 4.7, where a material component is issued to a vendor as part of the subcontracting process, MRP will re-order additional stock, if levels drop below the re-order point, the system does not take materials provided to vendor into consideration. Is there a configuration setting that will take into consideration the quantity provided to the vendor as available stock when running MRP and therefore not generate an order until the material componenents are consumed and the goods receipt for the subcontract item carried out.
Thank you

Hi,
Please look at this SAP note: 170597

MRP VS MPS

Dear All,
I understand MPS will considered for high value material (normally imported material which costs more) & its has direct impact on your profit margin. So identify those material & run MPS for those items seperately. (Normally in ABC Analysis, A indicates high value & low consumption material) .So all "A class" material will be considered for MPS run.
This is my understanding about MPS. The client has to take the decision about identifying material for MPS run. Based on their input, i will select the MRP type as MPS in material master.
Now, they are asking me to consider all the materials for MPS run without proper study.
What will be the better approach to make them to understand the difference between MRP & MPS?
Your inputs are highly appreciated....
Regards
Senthil

Hi,
Thank you. One more query....
Let us consider the below scenario:
The below scenario is for make to order (MTO). I got the item A (FERT)Sale order for 100 quantity.
My BOM header material is "A" (FERT item) & MRP type is PD (Non MPS item).
I have created BOM for material "A", which consists of three items as below:
Item 1: "B" (HALB item) & this is MPS item (MRP type : M1). Item B in-turn has the BOM, which consists of two raw materials (ROH) namely R1 & R2 (both Non MPS item & MRP type PD).
Item 2: "C" (ROH item) & this is Non MPS item (MRP type : PD)
Item 3: "D" (ROH item) & this is MPS item (MRP type :M1).
Now i am running t.code MD41 (Single-Item , Multi Level), for item "B" (HALB item).....
clarifications:
1. As you said, the system will create planned order for items B, R1 & R2 . It just plan for the item (ie item B) & immeadiate one level down item (ie R1 & R2). Am i right?
2. Yesterday i have already run MD41 for item B. I have forgotten to run MD41 for item D yesterday, even it is MPS item. Now i am running MRP (MD02) for BOM header material "A" (Non MPS item). It is regular MRP run. As per my understanding, the system will do the following.
i. Since we have already run MD41 for item B & also it is a MPS item, system will NOT consider Item B for MRP run (MD02).
ii. Item R1 & R2 will NOT be planned again during MD02, even those items are Non MPS items. Because we have already run MD41 (MPS-single item, multi level) for Item B ( R1 & R2 is BOM component for BOM header material B). That in-turn create planned orders for R1 & R2 also. am i right?
3. Since item C is Non MPS item & planned order will be created for item C as a result of MD02 run. am i right?
4. Item D is MPS item. But i have fogotten to run MPS (MD41) yesterday. Now i have already run MD02 without running MD41 for material D. System will NOT consider item D for MRP run since it is a MPS item. So NO planned orders will be created for item D at the end of MD02. But after MRP run, we can run MD41 for item D. (Even though is not a suggested practice). am i right?
4. what is the functional reason to run MPS before MRP run?
Thank you
Senthil
