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.

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 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,

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).

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....

How MS/MRP and Oracle ASCP will work for Manufracturing for a Item 'PEN' .

Hi All,
I am having oracle MS/MRP and Oracle ASCP.
I want to manufrature item as PEN. All items are buy items
Can any one tell here how MS/MRP & ASCP will work to manufrature a pen.
What will be the flow of these 2 modules?
Thanks,
Edited by: user11362919 on Jul 9, 2009 1:11 AM

Hi
If I understand your qn correctly you are asking about a writing pen ?
Lets say it has parts like pen body,refill,top and cap all these items will have ''buy souricng rules''.
Based on demand for the end item ''Pen'' AsCP will explode BOM for the Pen and suggest supplies as planned orders for the components , which can be converted to Std PO or BPA release automatically. All that MRP module could be of use to you is to define Forecast demand for the item.

HELP - MRP and Stock in subcontractor!

Hello SAP gurus,
I have a little problem with MRP and the stock in the subcontractor.
This is the scenario:
PLANT..........MRP ELEMENT..........QUANTITY
2100.............Free Stock..................500UN
2100.............Reser..........................700UN
2100.............PurRqs........................200UN
And I the stock in the subcontractor for the same material is 300UN...
Why is MRP creating a PurRqs instead of a stock transfer from subcontractor.
The Scope of check is considering subcontractor stock...
Can you please help me?
Thanks in advance,
Adelmo Silva

Hi,
As i Know MRP will not Consider , the Stock Available at Subcontractor. During the Net requirement calculation it will consider teh stock available at Plant. That is why it would have created PR.
During material Availabilty check it will consider as per settings at Scope of the Check.
One more Option is MRP area for the subcontractor , for More details please refer below SAP help.

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.

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 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

Use of different production versions for MRP and costing

Dear PP Gurus ,
We have a scenario in which there are multiple production versions for a particular product .The MRP run as welll as costing run considers only the production version 0001.
We would like the system to consider different production versions for MRP and costing ..that is 0001 for MRP and 0005 for costing .
Is this possible ... if yes ...Kindly suggest the config and master settings for this to happen .
Ram ~

Dear Ramakrishna,
For doing the costing for a specific production version use CK11N,under quantity structure tab key you
can assign the prod.version which is to be used for costing purpose.
While taking MRP if you want to consider the particular Prod.version,assign the demand to the
correct prod.version under schedule line tab in MD61.
Otherwise the system always picksup the first prod.version for MRP.
One more alternative is you have to lock the other prod.versions if you want the system to consider a
particular prod.version.
Check and revert back.

MRP and Availability check clarification

while browsing the forum, many experts here mentioned in old threads that MRP and availability check are two different (independent) concepts. I am really confused on this one. let me put my understanding here and plz experts help me if I am wrong with a figurative explanation, so that will be easy for understanding.
Assume this is the scenario as of today.
Plant stock for material x u2013 100
Reservations for material x u2013 70
Incoming receipts for material x u2013 50
So net stock = 100 + 50 -70 = 80
sales order arrived for material x u2013 100 and availability check is done. Results of availability check says 80 can be confirmed and 20 can be confirmed on later date.Transfer of requirement for quantity 20 is done to MRP. Mrp runs and creates planned order for 20.
In the availability check config ovz9 if I say donu2019t consider reservations, then when availability check is done for 100 quantities..system will confirm 100 because available stock according to system will be 100+50 = 150. So transfer or requirements are not sent to mrp.
So isnu2019t mrp run directly dependent on availability check?

925,
sales order arrived for material x u2013 100 and availability check is done. Results of availability check says 80 can be confirmed and 20 can be confirmed on later date. Transfer of requirement for quantity 20 is done to MRP
No. 100 pcs requirements are passed to MRP.
In the availability check config ovz9 if I say donu2019t consider reservations, then when availability check is done for 100 quantities..system will confirm 100 because available stock according to system will be 100+50 = 150. So transfer or requirements are not sent to MRP.
No, 100 pieces requirement are passed to MRP.
This behavior depends upon how your 'transfer of requirements' is configured, which is an SD setting. Normally, unless the fix date qty field is set in the sales order, the entire 100 pc requirement is passed to MRP in all cases. The assumption is that you have accepted the sales order and will 'some day' need to issue and sell the parts. You need to begin planning for this event now.
When MRP subsequently runs, it will net out the supply elements (stock and inbound reservations) and will from this calculation determine how much needs to be built. It then proposes a solution (planned order or purchase req).
ATP check seldom has much impact on MRP. You are correct in realizing that the ATP check must be consistent with MRP and with your chosen MRP strategies, in order to provide an end-to-end business process that is logical and meets all business requirements. However, in SAP these two functions are separate.
