Supersession MRP

Hey, we're using Super session, and mrp type reorder point.
everything is going well but i have one problem
during MRP Run, requirement which come from sales order didnt affect my available qty.
does anyone know how to solve this?
thanks

Dora,
The 'Lot for Lot' capability is provided only with ASCP.
Here is a suggestion. In discrete manufacturing, you would need to create an alternate routing (and BOM) for this item to represent the second manufacturing line (alternate process). MRP does not provide the capability to automatically switch to the alternate routing to smooth capacity or avoid lateness, only ASCP constrained plan do.
A Planner could build this schedule manually in the MRP workbench. The Planner would firm planned orders using the alternate routing (second manufacturing line). Select 'Overwrite' (firmed orders) = "Outside Time fence" in the MRP plan options. MRP will retain and net all the firmed planned supplies prior to creating new supplies. New planned orders will always be created using the primary routing with this setup. You can release all of these planned orders from the planners workbench after selecting the appropriate routing.
With MRP, I recommend that you use Planning Time Fence to control to prevent new supplies from being created earlier than your firm planned orders.

Kevin

Forecasting for supersession chain

We are using the automatic reorder point MRP type
when forecasting is run the system system takes individual material for determing the forecast and not the the material as a part of supersession chain.
Let me give u a example.
material "A" has a consumption in the past
material "B" is a new material (has no consumption at all) and
material "B" is superseeding material "A"
when the forecast program runs, it will calculate a reorder point for
material "A" because it has a consumption history, but the reorder
point of "B" is zero because material "B" has no consumption history
Suppose no stock,PO, or PRs for material "A" & "B".
When the MRP runs, it considers only the last supersession which
is "B". of course "B" has a zero reorder point and so no PRs are
generated.
Is there is a way to consider the summation of the reoder points of all the supersession chain materials in the MRP or to make the forecast runs only on the last supersession taking into account the consumption of all supersesion chain materials.

Hello shyamsundarl
If you are using the DIMP solution only for the Supersession
functionality and not for the MPN, you would only have to activate
DIMP_SDUD Business Functions.
Please read note 849981 and discuss the issue with your SAP consultant.
Consider that settings of buisiness function sets (TA SFW5) are
irreversible... so please do the switch first on a dev system only,
and test carefully!
Enda.

Order of delivery schedule line counter at schedule agreements from MRP run

Currently we are using schedule agreements for our long term external suppliers, but we are facing a problem with the order of new delivery schedule lines created during MRP run.
Because of master data settings like, lot size, rounding value, plan delivery time and planning time fence to set as firm new requirements, multiple schedule lines are created with no order for schedule line counter.
Does anyone is aware of a BADI, user exit or customizing control to have this schedule line counter in order?
Thank you

MRP - Auto creation of del schedule lines based on planned delivery time

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

Nirav,
This subject has been discussed repeatedly in this and other forums. I must assume that you overlooked the rules of engagement, which state that you should first search the forums and other public sites, before posting questions here.
Standard SAP MRP cannot be made to generate multiple items in a Purchase requisition. The functionality you seek is usually achieved when converting purchase reqs to Purchase orders, where many single purchase reqs can be adopted into a single Purchase order.
You also might want to investigate use of Vendor Scheduling agreements.

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

Schedule lines are not getting generated through MRP

Hello Experts,
While running MRP, we observed that the system is creating PR instead of schedule lines, although all the necessary prerequistes to generate schedule lines through MRP are maintained. For e.g.
1. MRP Schedule line relevant indicator '2' is maintained in the Source List.
2. Sch. Agreement dates and Source List validity dates are same.etc...
Further after some analysis, we observed that if we change the source list validity from date to some back date then system is creating correct schedule lines.
Example: Material M1; Planned delivery time 7 days; GR processing time 5 days; MRP Type PD; Lot Size WB;
SA validity dates - 07.09.2011 to 31.12.2011
Source List validity dates - 07.09.2011 to 31.12.2011
If MRP run on 12.09.2011 and source list dates are retain same as mentioned above, system creates the PR.
If MRP run on 12.09.2011 and source list dates changes to 05.09.2011 to 31.12.2011, system creates the schedule lines.
Could you please let us know, why the system behave like this?

Dear,
Welcome to SDN,
In transaction OMDT you have to enable the indicator create schedule lines
In MD02 MRP control Prameter here select the Delivery schedules -3- Schedule line. Processing Key as NETCH and Planning Mode - 3 delted and recreated.
Maintain source list ME01, in that put MRP indicator as '2' i.e. schedule lines via MRP.Put your agreement no in that.
If u run MRP properly u will get schedule lines automatically in ME38.
Make the schedule agreement, make it source relevent in the source list make is FIX and MRP indicator as 3.

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

*MRP unable to create Delivery Schedule Lines in MM Scheduling Agreement*

Hi Experts,
I need your help...
The issue is, in-spit of maintaining Source List with an u201CScheduling Agreement with item No.u201D & u201CSource List Usage in MRPu201D as 2 (Record relevant to MRP. Sched. lines generated automatically), MRP run does not generate Schedule Lines, instead PRs are created.
Please help me to understand such behavior and fix the issue as the requirement is to generate Schedule Lines only.
Thanks,
Pratap

Hello
Please check
1) Source List maintained properly in terms of Material # ; plant # ; proper POrg ; Schd Agr # and line item# ; proper validity date & MRP relevant indicator
2) Please also check Quata arrangement if you are using. whether % is maintained correctly against the vendor
3) MD03 , Delivery schedules- should be 3
4) check your planning horizon whether it is NETCH or not
5) check material master -MRP2 view, Procurement type is F- external procurement, schedule margin key if you are using
if everything above is set, then I feel it should work
Also please verify-
lot size, safety stock and the corresponding prod volume for MRP input v/s the stock available in MMBE
example.
MD04, we can see the open del lines.
if SS = 50 , prod volume is 150
1) if MMBE shows 200 then it wont generate any schedule.
2) if MMBE is 180 and your lotsize is 40, then after MD03, you will have a schedule line of 40 (provided if everything is set properly)
Please ensure there are NO open delivery lines . if you find such in MD04, then please close open delivery lines
in calculation of MRP, system considers such open delivery lines are going to receive and no additional schedule line generated even after MRP run
thanks

MRP is not working for one material

Hello,
I've run MRP without problems, but now I have a problem with one material. It is strange because if I copy that material with MM01, create the BOM and the run the MRP, everything works fine with the new material, but not with the old one.
Any idea why it could be not working, while the copy works perfectly?

hi
First of all check have u maintained MRP parameters correctly
( MRP type etc.)
Though u have created BOM but if parent material has no requirement then it will not create any requirement for ur created material so check whether parent material is applicable for MRP or Not

Cross Plant Planning- MRP activation indicator turned after the creation of Material code

Dear Experts,
Working on Cross plant planning, where 1001 Production plant will stock transfer material to 8 different plants.
Right now, only 10001 plant had MRP and planning file entry ticked in customizing OMDU.
The other 8 plants have Materials codes created and MRP views extended but no MRP activation is ticked.
Now, to have Cross plant planning MRP set, I have done necessary configurations, Scope of Planning, Special Procurement 40, and parallel processing is configured. All master datas are set properly. Tested few scenarios in IDES, working fine.
If my understanding is clear, than I thin I need to run MDAB, activation of planning file and MDRE, Planning file Consistency Check, because MRP will run in background?
Is this correct or something more needs to be done ?? Please suggest
Please also tell what is the use of MDRE t code.
Best regards
Shailesh

Hello Shailesh
MDAB (RMMDVM20) is at plant level, you need to create different variants as per your plants
Create a variant for the new plants and then schedule a job for these variants.
Check customizing transaction OMDU -> set up planning file
entry and consistency check of planning file entries.

What are the criterias to consider while deciding when to run the mrp?

Hello Friends,
Actually i was just thinking,if any company wants to run the mrp for planning than how to decide,when to run the mrp(daily,weekly,monthly).
One of the factor,while deciding this could be the raw material procurements,right?if they procure raw material once in a month than they should run the mrp once in a month.(even we can control this by keeping monthly lot size,if you run the mrp every week).
What could be the other reasons?
Thanks and Regards,
Jitendra Chauhan

Dear Jitendra,
As said by our other forum friends it depends on the business requirement.
In one of my project as the client were recieving monthly plan for their production MRP was carried out monthly.
It can be based on the production plan or say sometimes the maximum lead time for producing a product.
Also Check this link,

What are the dependent master data for running MRP

Hi Experts,
My client wants to Run MRP After 8 Months of implementation. Now i want to know
1) What are the Master Data need to be check. They are Using the Strategy 20.
2) They have confirmed sales order for few customers. Forecast sales orders for few customers.How to map it in sap.
3) Where will i get Gross Requirement in SAP. Because MRP run will generates the net requirements.
4) Is there any report in SAP displays the Forecast values for the selected material.
Please help me on the above points.
Thanks
Satheesh

HI Vishwa Upadhyay,
Thank you Once again,
The first point is cleared. Can you please suggest me on the 2,3& 4 points please. What are the configuration settings needed for the different sales order type( i.e.. confirmed and forecast)
Thanks

Creation of SDEB's for MRP type = VB materials.

Hi Gurus,
When we run plant wise MRP, SDEB's are created instead of Purchase requisitions for all Manual re-order point materials. We understand that SDEB's are created when the stock of tha material is above tha Re-order point, and this SDEB's indicate tha MRP controller whether he can create manually Purchase requisitions or not.
But, we are getting these SDEB's for the materials that have stock below the Re-order point as well. Which is not correct i think.?
For your information, when we run material wise MRP there are no SDEB's at all.
Please explain what might be the Root cause and the solution to over come this..
Thanks for your understanding..
Naveen.A

Dear colleague,
without checking the issue it is difficult to know if there is an error.
Please check if the following information can explain the behaviour of your system:
A)When you do MD01 or MDBT the creaton indicators defines in the
customising are used . whereas when you run MD02 or MD03 the creation
indicator on the individual screen is used.
Single-item planning and total planning follow a different logic
concernng the creation indicators.This is also described in the
documentation for Master Planning/Materials Planning (Chapter 4, Section
2) and in the Implementation Guide.
Single-item planning:
        The entered creation indicators are generally valid.
Total planning:
       The entered creation indicators are used as default values.
       For materials from an MRP group, the values from the MRP group
       apply (if available).
       The creation indicator for delivery schedules can additionally be
       specified per plant. This is used if nothing was specified via
       the MRP group.
       Thus, the priority is as follows:
      1. MRP group
      2. Plant
      3. Initial screen
B)In MD02 system can de multilevel (For components of a header Materia)
or/and Multiplant (Stock Transfre ) planning. In such cases for all the
materials involved the creation indicator used in the screen is used.
C)The creation indicator makes sense only for materials having
procurement type external procurement (F) in material master. For the
materilas which are produced in house (Procurement type E) system will
always create planned orders.
    And Materials having procurement type X(Both procurement types ) is
treated as Inhouse produced material by planning . Thus for such
materials system will always create a planned order. Now this planned
order can be converted into a production orer or into a purchase
order(via purchase Requisition).
    When you run MRP with "Create Purchase Requisition " in the opening
period , then the syetm uses in the opening period defined via the
scheduling margin Key. In material master , MRP 2 View we maintain
scheduling margin key. And in Transaction OPP1->Planning->Scheduling and
Capacity Parameters ->Define floats we maintain the opening periods per
plant. I am attaching details of Opening period :
   opening period: Opening period is the time which the MRP controller
needs to analyse.Thus he has this buffer with him to rectify any issues
before converting the planned order into purchase requisition.
The opening period is only used in backward scheduling.
Suppose There is a requirement for a material on date =RD1
Let the Goods receipt processing time is= T1
Let the planned delivery time =L1
Let the purchasing Processing time = X1
Let the opening period for this material is P1
Time line for external procurement:
        Planned Del   Pur proc         GR Process
          Time            Time          Time
___|__________|_________|___________|___
              L1            X1         T1
   SD                                         RD1
Now accoring to Basic scheduling:
   Receipt/Requirements Date(RD1)
   Release/Start Date(SD) = RD1-T1-L1-X1
Now let me explain to you when the planned order an purchase
Requisitions are created:
Let us say the date on which you do MRP be MR1
OD = Opening Date
From above diagram :
                                 Opening Per
                                 In Sch Mar Key
__________________|______________|
XX                          OD                 SD
                                              Release/Start Date
If your MRP date(generally Today) is lying between XX and OD (and
excludind OD)then
MRP creates planned order and if it lies between (and indclind OD)
OD and SD then we create purchase req.
when your MRP date comes between the period OD and SD then you do not
have time left to analyse and therefore instead of you in such cases
forgetting and delaying system automatically creates purchase req.
      In general if , if your order start date or release date is after
the opening period from today then MRP will create planned order.
Oterwise it creates Purchase req.
Check also if you have the note 1063969 applied in your system.
I hope it solves the issue. Otheriwse I think you should open an OSS message with connection to your system,
best regards,
maria

Hi avinash
consulte your MM guy material master screen group and selection is done by MM guys in general. There they can do setting for this.
Also why you need MRP group. If it is maintained. It should be done properly otherwise it will create lot of problems.

MRP - Ponto de Ressuprimento (VB-HB)

Senhores, devido á crise, preciso mudar a forma de executar o MRP, que até então é o tipo VB e o tamanho do lote HB (estoque máximo). Só que eu preciso comprar até atingir o ponto de ressuprimento (estoque mínimo) e não o estoque máximo. Há alguma forma disso ser feito? Não gostaria de perder o histórico do estoque máximo. Aceito sugestão para fazer o MRP e comprar pelo estoque mínimo.

Oi Antonio,
Eu imagino que o link a seguir possa ser de alguma utilidade:
