Setting-Up MRP

Dear Experts,
Appreciate if you can explain the process of MRP which relates to Projects. Further following are other concerns which I have related to this topic:
u2022     What is the difference between a Standard BOM and a Material BOM?
u2022     What are the ways of performing a MRP Run?
u2022     In a MRP Run can I define a scope?
u2022     Can I set a Re-Order level for/in a MRP Run? Or these are two different concepts?
u2022     What are the main configurations in MM and PS to implement the concept of MRP?
Very much Appreciate you guidance,
Dileepa.

Hi
u2022 What is the difference between a Standard BOM and a Material BOM?
Both are same , there is no diff b/w these two. Only the name is diff.
What are the ways of performing a MRP Run?
MD01 --- Plant level MRP Run
MD02 --- Single Item Multilevel (Material wise)
MD03 --- Single Item singlelevel
MD50 --- Sales order wiseMRP Run
MD52 --- Project Wise MRP run
u2022 In a MRP Run can I define a scope?
Yes you can define a scope a planning in MD01 . In scope of planning you can define some group plants and run MRP for them.
u2022
Can I set a Re-Order level for/in a MRP Run? Or these are two different concepts?
This is called MRP type, you have MRP type PD, VB , VV etc...
In that if you want re order point planning you have to use VB -- Manual reorder point in material master MRP 1 view.
u2022 What are the main configurations in MM and PS to implement the concept of MRP?
You have to define MRP plant parameters in OPPQ t.code. and you need to activate the MRP for your plant.
Thanks

Any difference setting background MRP run in MDBT and SM37

Hello,
Just wander if there is any differences setting up MRP run in MDBT or in SM37 to run RMMRP000? This is to run MRP at plant level in background.
Thanks,
Lin-Lin

Hi,.
Both MDBT & SM37 are having same program (SAPLBTCH) . MDBT is Foreground job as well as Background job.
SM37 is only for Background job only.
Pls let me know any further clarification.

Setting up MRP for the first time

Good afternoon,
what are the steps that need to be done to set-up MRP?
Thanks in advance,
Guy

Customizing settings
OPPQ - Copy the std settings from 0001 to your plant
Master data - masterial master with MRP view settings
Customizing settings
In OMDU - in MRP tab page activate the MRP for the plant
Setup planning file- create a variant for the plant and execute
Consistance check - createa variant for the plant and execute.
in the next node - Define Planning File Entries for Goods Movements activate PPE for the plant.
Define Parallel Processing in MRP here define the server and sessions/server.
Check Storage Mode for MRP List - do not have any tick for the check box-transp MRP.

How can I set up MRP to use QI Stock at the Vendor, for Planned Ind Reqmts

Hi experts,
We are running ECC 6.0.
In one of our plants, we have a lot of components that are available as QI stock in Material Provided to Vendor status.
We build SKUs (MRP type M3) at the top level in the BOM, and the SKUs use the above components. We mostly enter demand at the SKU level in the plant (LSF).
We have set up the source list for all the SKUs in this plant with MRP = 1.
When MRP runs for the components (MRP type PD), system is able to first allocate the QI stock to any of the requirements that are driven by the higher level SKUs. Only then, it creates Planned Orders for the components to account for the shortage.
Issue : We now enter forecast (LSF) directly at the Component level (for some Materials). Now, even though we have excess
component stock to handle all the demand (dependant demand driven from the SKUs + LSF at the Component level), system doesn't allocate the excess QI stock to the LSF demand at the component level. It just creates Planned orders.
Strategy Group for both the SKU and Component is 10. We don't have MRP Areas implemented.
I tried setting up the source list at the Component level using the vendor but there is no use.
Does any one have an idea on how this can be addressed?We want to be able to use up the QI stock first before we create Planned orders.
Thanks,
Rao

How can you create QI stock first before your planed order from MRP run? Do you know this is not standard SAP ?

Setting up MRP in multiple plant scenario

Hi,
We are planning to implement MRP in our system. I understand that MRP is normally carried out at a plant level. However, since we have multiple plants (from which we ship our products), we want to be able to run MRP across multiple plants. To elaborate, we want to have one forecast figure for all the plants (basically forecast at material level, NOT by plant), consider inventory across all the plants, and then based on that, we want to be able to generate PRs/POs. It would be ok to create POs with one default plant and if needed, change later the receving plant on the POs manually based on the inventory situation in each plant. Of course, we need to tie in the demand situation (customer orders) in each plant in the MRP process.
Is there a way to do this using standard SAP or with some amount of customization?
Any insight/ideas would be greatly appreciated and help us move in the right direction.
Thanks,
Prayarna

Total Planning
Use
Total planning covers the planning of all the materials that are relevant for requirements planning and includes the BOM explosion for materials with a bill of material.
You can use total planning for a single plant or you can use the scope of planning to control whether the total planning run is executed on a multi-plant level
for several plants
for one MRP area
for several MRP areas
for a combination of plants and MRP areas.
Prerequisites
Only for multi-plant planning with scope of planning:
You have grouped together the plants or alternatively the MRP areas, which are to be planned together, in Customizing for MRP in the IMG activity Define scope of planning for total planning.
In Customizing for MRP, you have made the necessary settings for Parallel processing in the IMG activity Define parallel processing in MRP.
Features
Defining the Scope of Planning
You can define different scope of planning groups in Customizing.
You specify the sequence of the individual MRP units (plants or MRP areas) for each scope of planning by entering a counter. This counter defines the sequence in which the MRP units are to be planned.
You can enter as many plants as you like in the scope of planning.
If you have activated material requirements planning with MRP areas, the entry of a plant thus includes all the MRP areas of this plant. During the planning run, the MRP areas of a plant are always planned in the following sequence: plant MRP area, storage location MRP area, subcontractor MRP area.
You can, however, also enter one or several MRP areas in the scope of planning and thus restrict the total planning run to these MRP areas.

Setting up MRP parameters for plant A and plant B

hello,
how could i Modify production plant parameters in order to run MRP for plants A and B (Option "Carry Out Overall Maintenance of plant parameters" in the manufacturing customizing).
thanks
JJ

Use can define this in follwing SPRO path->Production->Production Planning->Material requiement planning->planning-define scope of planning for total planning.
In this you can maintain both plant for scope of planning.

How to set MRP by MD04

Dear
I have Material master by setting in view MRP1 like below :
MRP Type = VB
Reorder point = 10
rounding value = 5
Now, my Stock on hand = 10
When I use tCode MD04 for listing stock/ Requirement the result "MRP element" for PurRqs nothing, so I can't Create PR by MD04
but if when my stock on hand = 9, I found that
Now My question : How to set for MRP, in order to "When My stock on hand = Reorder point then I can use to create PR by MD04 ?"
thanks
imron

Hi,
The system will not generate a P req until the stock has fallen BELOW the reorder point (not equal to it).
So if you want the system to generate a P req when the stock reaches 10 you need to set the reorder point at 11.

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

Sales orders ans reservations not taken into account on MPS / MRP

Hello,
I am implementing the MPS / MRP and I have the following problem:
I have modified the necessary material master fields to take into account some materials on the MPS / MRP execution. These fields are MRP type, Lot Size, Strategy group and Availability Check.
Then, executing the MPS / MRP I have realised that only the sales orders and reservations created after the material master modifications are taken into account when I execute the MPS / MRP.
I suppose this is because the sales orders and reservations created before the material master modifications did not create the requirements because the availability check was not set for the material and so on... but I need to take into account these "old" reservations and sales orders .
Is there any way to "update" these orders and reservations?? Or I need to delete them and create new ones??
There are several sales orders and reservations created before the material master modifications. I think there have to be an standard way to update them.
Thank you very much in advanced,
Jordi.

Dear,
Are you getting these reservation in MD04?
Check the Planning file entry for these material in MD21 if not then create it through MD20 and take MRP run with planning mode -3 Deleted and recreated. And Processing key NETCH.
Also check the The firmed receipt is within the rescheduling horizon. The rescheduling horizon is set in Customizing for the MRP group (Transaction OPPR, Table T438M). A default value can be predefined in the Customizing of plant data (Transaction OPPQ, Table T399D). define the longer duration for it.
The firmed receipt (the MRP element) participates in the rescheduling check. You can set which MRP elements participate in the rescheduling check in the Customizing of the plant data (Transaction OPPQ).
Else you can carry out modification A using the MD_CHANGE_MRP_DATA BAdI and the CONSIDER_RESB method without making a modification.

MRP creating multiple delivery schedule lines in PR

Hi,
We have activated MRP (type PD) where Purchase requiesition is auto created by system for requirement quantity. We require to optimize delivery schedule in such a way that entire PR quantity is broken into various delivery schedule based on planned delivery time and requirement. Scenario can be further explained with following example.
Material Requirement for a month is say 1,25,000 units
Closing Stock say 25,000 units
PR Generated by system for 1,00,000 units. The entire quantity is schdulled with only one delivery schedule line as per planned delivery time.
The requirement is to generate multiple delivery schedule lines automatically in Purchase requisition based on planned delivery time so that Purchase orders can be placed with system generated delivery schedule lines.
How can it be achieved ?
Regards,
Nirav Kinkhabwala

Dear
Are you dealing with Single vendor where you want Multiple Schedule Line item through single PR which should be generated through MRP run ??
What you will have to do is to set up the Outline Agreement or Info Record for your vendor and material and then create the source record for this vendor- material relationship and make sure that this source record is set as MRP relevant. Once MRP is run, the vendor is automatically defaulted to your PRs. If in your material master, you have defined the same purchasing group for various material numbers, then with Transaction ME59, it is feasible that you can combine various PRs of the same purchasing group by flagging onto the 'Per Purchasing Group' indicator checkbox. Make a trial test and let me know how it goes.
Or you can use Qouta arrabgement in that case for different vendor .Please refer : Multiple Requisition line itme for Quota arrangement
Just check and revert

MRP Out Put Schedule lines date format to month

Hi Friends,
I am working on SAP4.7 Version.
I have maintained all the relavent MRP datas in material master.
Like MRP type - PD,
Lot Size- MB ( Monthly Lot size).
I have created planned independent requirement in MD61 monthly wise for that material.
I have given Schedule agreement number in Source in List with MRP indicator - 2.
I am running MRP for a material with MD02 with MRP parameter Delivery schedules -3 (Schedule lines) .
The MRP running succesfully and creating delivery Lines with delivery dates.
But the requirement by the client is..
The delivery lines should be generated in month wise.
How to convert the schedule lines generated in day format to Month format in MRP run out put?
While creating schedule lines with ME38. we have option to select the day format / month format/ week wise?
But the MRP out put always generated in date wise?
Any one knows what changes i should make?
Guide me ..
Thanks & Best Regards
Giri

Hai Boss
Can you throw some light , how you set default mrp indicator month wise with the help of ABAPER.
My client requirement also same like you. Yours is month, mine is week. Pl help me out.

Schedule Lines are not getting generated after MRP run.

Hi,
I have an issue where a SA exists for the parent material with item category L (subcontracting). The parent material has a valid BOM and some sub components as well. I see in CS03 that BOM is fine with validity dates for the parent material. A valid source list also exists for the parent material where SA is present as the source of supply with MRP indicator as 2. Now when i run MRP for the parent material using MD02 (NETCH), with indicators as below:
Create pur.req. 2
Schedule lines 3
Create MRP list 1
Planning mode 1
i don't see any schedule lines in MD04. Instead it creates a PR that too without any source of supply.
In master data for the parent material MRP type is PD with Procurement type F and special procurement key 30. I have checked and every thing seems to be fine still MRP run doesn't create schedule lines.
Any help is appreciated. I can give more info if required.
Thanks.

Dear Rakesh,
Scheduling agreement:An outline agreement against which materials are procured at a series of
predefined points in time over a certain period.
1.For this you have to first use ME31L for creating scheduling agreement and then ME38 for maintaining scheduling agreemnet
schedule.
2.Ensure in the source list after maintaining the material,vendor combination the setting for MRP relevancy is set to 2 - Record
relevant to MRP,Schedule line generated automatically.
Moreover you have to use value 3 for delivery schedule line which is one of the MRP control parameter while taking MRP run.
So for the materials for which scheduling agreement exists,schedule lines will be generated.
Check and revert back.

MRP keeps pushing delivery schedules out, refusing to firm them (ME33L)

I hope someone has seen something like this before and can let us know where to look. MRP keeps pushing our delivery schedules out even though it is recommending that they be rescheduled in. What we'd like to happen is for MRP to leave these schedules alone so that they would move inside the time fence and be firmed automatically. Here is what is happening:
Part X, MRP type P1, firming type 1, MRP group blank. Planning time fence 05/07/2007, available quantity -20.
Three schedule lines exist for 05/07/2007, two for 10 and another for 30.
MRP will run tonight. Processing Key = NEUPL, purch req = 2, sched lines = 3, MRP list = 1, planning mode = 2, scheduling = 2
Tomorrow, the planning time fence will be at 05/08/2007 and the three schedule lines will move out to 05/08/2007. The won't move inside the planning time fence and firm up. They SHOULD BE 05/07/2006 and firmed!
We originally thought that we may have to create a release with ME84 before these would firm, but it made no difference. They still won't firm unless someone manually changes the date on each and every schedule line.
Does anyone know what we can change or run to get these schedules to firm up instead of having them pushed out continually?

Hello Randy,
thanks for the update. I didnt remenber this customizing indicator when posting.
Still wondering why planning matters here. I think it should have the same result for all planning modes. Of course planning mode 3 in general should be avoided for performance reasons.
For interested observers I attach the description for this setting in MRP customizing.
Regards, Martin
Indicator: Only Firm Transmitted Schedule Lines
In this step, you can set an indicator which is used to set only those schedule lines that have been transferred to the vendor.
You can firm schedule lines within the planning time fence (in the same way as planned orders or purchase requisitions) according to the master schedule item firming logic. The planning time fence is a number of days that is calculated into the future starting from the current date. Therefore, the last date of the planning time fence changes every day.
In the firming logic, existing schedule lines are also firmed as soon as they move into the planning time fence.
Schedule lines that lie outside the planning time fence and whose quantity is adjusted in the planning run due to a change of the requirements quantity are firmed with the new quantity as soon as the schedule lines move into the planning time fence.
The schedule lines are transferred to the vendor for the amount recorded in the stock/requirements list at the time of the data transfer.
If you only want to firm the schedule lines in the planning time fence that have been checked and transferred to the vendor, you can use the indicator, Only firm transmitted schedule lines. By selecting this indicator, the system only firms the schedule lines that have been sent to the vendor.
For schedule lines whose quantity has changed and which have moved into the planning time fence, the following occurs if this indicator has been set: if the MRP controller/purchaser does not confirm the procurement plan by sending the changed quantities to the vendor, the schedule line quantities that were sent to the vendor in the previous data transfer are firmed within the planning time fence. This guarantees that the system cannot firm any quantities that have not been checked. It also means that the vondor does not receive any messages for unchecked schedule line quantities.
Activities
Define the indicator per MRP group and allocate this MRP group to the materials for which this indicator is to be valid.
Further notes
The message transfer is a purchasing function. You can find it in the purchasing menu, Outline agreement -> Scheduling agreement -> Messages -> Print/transmit.

MRP auto creating and batching releases

Using standard functionality it's possible for standard Oracle processes to automatically create PO Releases within the Release_Time_Fence_Days. We want to use this functionality, but, the answer it provided was inappropriate.
The main issue is that if there are two MRP Planned Orders for different days and the Delivery Calendar indicates that they will both be delivered on the same day, the result is that two PO Releases are generated rather than one?
This makes it difficult for the Receiving staff who would have to book material in against different releases; doubly awkward if the material was delivered all at the same time.
Does anyone know of a way to sum/group the releases at all (by vendor/part/dock date)?

Bren

Issue in PDT of PR generated from MRP

Hi All,
We had a issue in the PR generated from MRP. Actually the Planned delivery time(PDT) of the PR(Purchase requisition) is supposed to pick from the PIR(Purchase info record) for the given material if PIR is existing, instead the PR generated from the MRP is picking the PDT that is maintained in the Material master. After our analysis, we are seeing that Purchase Organisation details is not mentioned in the PR and this PR is created from the MRP. How to ensure the Purchase organisation details are to be picked for the PR that is generated from the MRP run so that PDT from the PIR is picked up for the PR instead of PDT of material master. Can anyone suggest us does we need to maintain any setting in MRP Run?. How can we avoid this issue.
Thanks in advance.

Dear Aditya,
Check in OPPQ,for the plant whether the check box for determining the planned delivery time is set or not.
Scheduling according to purchasing info record or agreement
Determines whether the planned delivery time specified in the purchasing info record is used for scheduling in the planning run.
Use
If you set this indicator, the system checks whether a planned delivery time is entered in the purchasing info record or in the
outline agreement. This planned delivery time is then used to calculate the delivery date and the release date.
Dependencies
If you want to use the planned delivery time from the purchasing info record, you must maintain a source list entry for the
material in addition to the purchasing info record, and enter the same vendor in the source list as in the purchasing info record.
Check and revert
