DONOT RESCHEDULED IN MRP

hello friends!
i have problem in MRP run some of the orders get RESCHEDULed after its parent order get TECO status that i want to eleminate in the next MRP run
i have product say PA0160R3NRJ02000 & its component B01600140050F000
now i create production order of PA0160R3NRJ02000 then order reserved for B01600140050F000 as follows-
30.10.2007     ordRes     PA0160R3NRJ02000</b>     100-     100-
30.10.2007     PrdOrd     000001011171/PP01/Re     100     0
30.11.2007     OrdRes     PA0160R3NRJ02000          200-     200-
30.11.2007     PrdOrd     000001011173/PP01/Re     200     0
30.12.2007     OrdRes     PA0160R3NRJ02000          300-     300-30.12.2007     PrdOrd     000001011171/PP01/Re     300           0
now after creating 30.12.2007 production order of PA0160R3NRJ02000 for 300 qty.& if 30.10.2007 production order of PA0160R3NRJ02000 get TECO,then the situation will be as follows-
30.10.2007 PrdOrd     000001011171/PP01/Re 28.11.2007       100     100
30.11.2007 OrdRes     PA0160R3NRJ02000                      200-              100
30.11.2007 PrdOrd     000001011173/PP01/Re                 200     100
30.12.2007 OrdRes     PA0160R3NRJ02000                     300-     200-
if i take MRP run it will create 200 qty. plan order of B01600140050F000
now my problem is that i want order qty of 300 to be generated through MRP & 30.10.2007 production order 000001011171/PP01/Re not to be rescheduled
please give solution

Hi,
you can define in plant parameters oppq or via MRP group oppr which orders are to be included in the rescheduling horizon.

How to restrict RESCHEDULING after MRP run ?

Dear All,
We r using prodn. strategy 30. We don't take MRP run for finished material. First we create production orders for finished material & then we take MRP run to create planned orders for semifinished material.
After MRP run , production orders of semifinished material of previous month gets rescheduled . How to avoid this ?
We created production orders of NOV2007.
When we take MRP run today i.e. SEPT2007 to create planned/prodn orders of OCT2007 m/c shop plan. It shows wrong results. It is not giving right requirement for blanks .
PL' answer.

Hi,
In OPPQ/OPPR increase the tolerance value to a high value.
The system compares this value with the ( order finish date - reqmts date) and if it is greater the system do reschedules.
Ex tolerance value -
2
      diff bet ( order finish date - reqmts date ) -
5
     the system reschedules.
    so increase the tolerance value to 5 and see the results. The system does not
    reschedules.
OR in OPPQ disable the indicator for production order

MRP type: PD

When using PD for MRP planning, I found some interesting things.
For example:Material A, Safety Stock=12, current stock is 5 and there is a PO of 10 due July 15, today is July 13. Run MRP today, MRP generate exception message 20 to cancel the PO and an extra 30 to create a new PReq. Understanding that MRP tries to replenish the SS asap, as PD does, which suggests to cancel the existing PO and create a new PReq. The problem is the suggested Del.Date in the Preq is not sooner that Del.date in PO which is July 15.
Another material B, has the similar scenario of A, but MRP just does nothing to it. No exception message upone MRP run.
Does MRP perform nomally? Why MRP makes such decision for material A but keeps silent for B?
Thanks in advance.

JM,
MRP uses the rescheduling horizon to determine which of the existing firmed elements to consider as 'valid' to support an existing requirement. If a firmed element is inside the rescheduling horizon, MRP will recommend a reschedule (eg change the date). If the firmed element is outside the rescheduling horizon, MRP will create a new proposal, and may in fact recommend that you cancel the firmed element that lies in the future. If you maintain no resched horizon, MRP will ALWAYS create a proposal for an unmet requirement (in this case, your safety stock). The date of the new proposal will be consistant with your ordering policy. This is typically at 'planned delivery time' for purchased parts. Doesn't matter if there is an existing firmed order (PO) there already.
Rescheduling horizon is set by plant or by MRP group. So, the reason one material might be different from another would be
a. Different lead times
b. Different plant
c. Different MRP groups.
It sounds like you have not defined a rescheduling horizon, or too small a resched horizon, for matl A. If one is not defined, create one. If one is already defined, try increasing it..
You can review and alter resched horizon in IMG transactions OPPQ and OPPR.

Configurable exception message

I would like to have a configurable reschedule in and reschedule out MRP exception message that only tells me to move in or move out when I am at 50% (or some other number) above or below safety stock on a code within the planning time fence on an M1 code. Any ideas? I have looked at using MRP group reschedule tolerance but the issue here is that it is only good for values in days - I would prefer it to be more flexible than that per code.
Thanks,
TammyM

Tammy,
Safety stock concept means that system will always give rescheduling messages any time stock falls below safety stock.
If you do not want this a better way would be to use Reorder point planning with external requirements. this way you can have yr reorder point at safety stock level.
Example : Mat A has safety stock =10. Change that to RP = 10 with external requirements. that way anytime stock falls below 10 system will trigger planned orders/ PR's. Howevevr if additonal requirements come in say Sale order for 20 pc system will plan for those additional 20 pc over the 10 pc (RP).
Hope this helps. Else please come back.
thanks,
Ram

MRP Reschedules PO ahead of Scheduling Agreement

Hi,
We have a situation where one company code (Company A) buys product from a second (Company B) via an inter-company Scheduling Agreement. The schedule lines are generated automatically from MRP.
Company A now has a need to purchase a one-off quantity of the same product from an external company and so have subsequently raised a Purchase Order with delivery dates in the future (after the next requirement from company B is due).
The result of the MRP run has been to prompt rescheduling of the Purchase Order in to meet immediate requirements and only generate schedule lines from Company B after the full Purchase Order quantity has been used. This is not as required, as the dates on the PO are those that are achievable by the external supplier.
I can't find any settings that relate to a prioritising of MRP elements which would imply that a PO has precedence over a Schedule Line, and I would rather not fix the schedule lines of the Scheduling Agreement.
Has anyone seen this before, or knows what I'm missing.
Thanks

Hi suresh
The requirement goes this way.the sales person creates a scheduling agreement instead of a sale order.The next process is running MRP for the scheduling agreement .
Just he wants to know through a report what are the sceduling agreements peding for MRP run.

MRP Type V1 - Does it create Exception Message for "Reschedule-in"?

Hello Experts,
We are using MRP Type V1 (Which has the Manual Re-Order Planning + External Requirements). However we are facing and issue with the Rescheduling part. Scenario is as following:
Material ROP is - 5000
Open Pur Ord is - 5000 (due in 01 June'09) based on the Std Lead time of the Material
Stok on hand is - 0
At this point a Sales Order is entered for 1000 pcs
After MRP Run, we expect an Exception Message for the Purchase Order to have "Reschedule-in". But, instead, system creates a PReq for 1000 pcs and the required date is NOT the Sales Order required Date but based on the Std Lead Time of the Material.
I have set the Material Lead time - 60 Days
I have set the Reschedule horizon - 0 Days ( I even tried with different Days but NO use)
However, when I change the MRP Type to PD, system generates a "Reschedule-in" Exception Message for the Purchase Order.
How can I get the "Reschedule-in" Exception Message for the Purchase Order with the MRP Type V1?
Thanks for your help in Advance!

Anil,
Reorder point/External MRP performs net requirements calculation (within replenishment lead time). If the existing firmed supply elements minus the existing requirements bring the projected stock below ROP, it will propose an order that will bring the projected stock back to reorder point. The proposal will generally come at replenishment lead time.
In the normal business cycle, your sales order would confirm to lead time, and you now have a confirmed sales requirement at lead time, plus a new purchase req to bring the stock back to the reorder point. The scenario you have described is working exactly as it is designed. Consumption based MRP will not normally try to reschedule supply elements to match requirements inside of lead time.
Rescheduling horizon generally is counted from the end of lead time. It won't help you here.
I guess if you insist on having a reschedule message, you could change your lead time to 0 days. Not a wise move in my opinion. You then have locked yourself in your choices of types of Sales order availability checks into one that ignores lead time. You also have to find a way to let your buyers/planners know what the 'real' lead time is when they place their orders on the vendors.
I don't know why you are using a consumption-based planning type (reorder point). It sounds like your business requirements are that you actually need to be using a demand-type planning method (eg, your supply elements are driven by your demand, not by a reorder point/desired stock level). If PD works the way you want, why aren't you using it?

MRP Rescheduling messages with planning calendars

Hi Experts,
I have successfully set up a planning calendar and applied in material master with a period lot size so that MRP creates purchase reqs with a delivery date on a specific day of the week.
My problem is with the rescheduling dates that appear in MD04 for firmed receipts. These rescheduling dates align to the requirement date date and do not take into account the planning calendar.
Do you know if it is possible to configure the rescheduling to take the planning calendars into account?

Hi Timonthy,
I just had a similar problem last week and the simple answer was to remove the re-order point.
Then it orders only on the day it should (unless you again go below safety stock) up to the forecasted amount.
The other option is to maintain a delivery schedule as well.
That way it will always schedule the delivery on the day you want even when it plans on a day you don't want.
While SAP is not very consistent on what they call the two schedules, the one that is required for MRP is the planning calendar (order cycle) and the optional one is the delivery calendar. Delivery dates are moved to match the delivery calendar regardless of lead time.
Not too sure whether that helps, but it solved my problem.

Mass Reschedule of Purchase Orders - from MRP

We are using MRP (not ASCP). Is it possible to perform a mass reschedule of purchase orders (note, not purch reqs, but purchase orders), directly from the planner's workbench? I think it is not possible with MRP, but ASCP seems to have the functionality. Am I right? Has anyone got any workarounds or tips on how to mass reschedule given that MRP can't do it?
Thanks

You were also correct that ASCP does have that feature. You can reschedule the "need by date" of existing purchase orders from the ASCP planners workbench. You can query purchase orders by specific attributes (like category or supplier) and then adjust the dates and release these changes to purchasing.
MRP does not have the ability to reschedule existing purchase orders.

Rescheduling at material level or MRP controller level

Hi,
I have come across one scenario:MRP need date and PO delivery date are within one week no exception message will be generated.
We can acheive this by maintaining tolerance values in OPPQ/OMDW. But problem is user wants this functionlity for purchased parts only and not for Inhouse mfg. parts.
As per my knowledge if we maintain tolerance values in OPPQ and select all recipts elements these values are applicable for those one also.
To overcome this issue is there any standard config exist in SAP? or else please let me know any enhancement to resolve this issue
Thanks in advance for your valuable input
Regards,
Alex

Hi
Thanks a lot for your quick reply
Let me clear you this issue
User wants rescheduling tolerance values in OMDW. But there requirement is it should affect only for purchased parts and not inhouse parts. For inhouse parts they don't want to consider these tolerance values. Creation of MRP group is out of question in this business.
As I know if we maintian tolerance values in OMDW it will affects for all receipt elements. So my question is: Is there any enhancement available in SAP where we can apply this tolerance values for procurement type 'F' materials only. (Externally)

Alex

Reschedule Exception message in MRP

Hi ALL.
MRP suggests rescheduling a PO to create a new one for delivery in the past. The planner clicks the Processing Indicator (Dealt With). As soon as additional orders come in and change the quantity, the "Dealt with is over-ridden" Can this be prevented? Suppress "Reschedule" exception messages?
Please Advice,

Not to reschedule in the MRP run.

Hello!
I have product   P000GR00000000 consisting a
component say B000GR00000000 .
               If i create production order of P000GR00000000 for DATED 30.09.2007 of 100 EA.then order will reserved -100EA for B000GR00000000 & when i take MRP run it will generare plan order of 100 EA for B000GR00000000.Similarly if i create production order for P000GR00000000 for dated 30.10.2007 of 200EA.Then MRP run will generate 200EA plan order for B000GR00000000.
      Now, i create production order for P000GR00000000 of 300 EA for dated 30.11.2007 & meanwhile the production order of P000GR00000000 DATED 30.09.2007 is technically completed then order reserved for B000GR00000000 of -100EA will be cancelled.If i take MRP run now ,then order reserved of -300 EA for B000GR00000000 will rescheduled,that i want to restrict.
   Is there any solution Not to reschedule in the MRP run if order is TECO.
please give the solution.
regards,
mangesh

Hi Mangesh
You can define Rescheduling at plant level or MRP group level using OPPQ/ OPPR or OMDW. if you define at plant level then no need to create in MRP group and assign to material
secodly if you want to avaoid the Reschedule Exceptions then
You can define tolerance values in additon to Resheduling horizon. for the creation of exception messages, in Customizing. These values define a time period in which no exception message is to be created, despite the fact that a rescheduling proposal may exist.
If you don't want reschedule check for production orders then you can remove the flag against production orders in the firmed elements.
if you TECO the order Normally MRP should not consider while planning!
please check onesecond and come back
But Teco will allow you for posting (GR/GI)
hope this helps

MRP-Rescheduling Horizon

Hi Experts,
Could u please, explain what is Rescheduling horizon (OMDQ)?
In OMDQ , if I change planning horizon to 999 days from 100 days.What will be the effects of it?
Thanks in advance
Regards,
jay

Dear,
The rescheduling horizon is the period in which the SAP System checks whether the existing dates still suit the requirements situation for receipt elements that can no longer be automatically changed in the planning run. If the dates of a particular element are no longer suitable, the following exception messages are created depending on the requirements situation.
Rescheduling check is to change the dates of already existing firmed receipts which were not planned on the same day as the requirements day to suit the requirement.
For this we need to define a rescheduling horizon.
Rescheduling horizon defines the period for bringing the receipts that should be taken into account for rescheduling.
For further info: Please visit: http://help.sap.com/saphelp_40b/helpdata/pt/b4/7055967935d1118b3f0060b03ca329/content.htm
For second question, if you change it to 100 days,
If you put 100 days, for net requirement calculation, system will consider the firmed planned orders & receipts within 100 days.
If one firmed planned order is in 4 months before ie 120 days before, system will not consider for net req calculation.
Say demand is 100 on 23.09.08
Resheduling Horizon 100 days
Firmed planned order in 23.04.08
When MRP run system create planned order for 100 qty.
If rescheduling horizon 999 days, system will not create planned order & system propose reschedule the firm planned order to 23.09.08

MRP not rescheduling the planned order by itself

Hi,
After MRP i could see that the planned order is not present as per the date of the requriement whereas the planned order at a future date is given a Exception message 30 : Plan accordingly to schedule and proposed the date of the requirement. The requirement is beyound the replenishement lead time and hence MRP should reschedule by itself the planned order as per the date of the requirement rather than giving a exception message as above for a future dated planned order.
I am not sure what is it i am missing. Could you explain.
Thank you

Dear ,
MRP will re schedule the planned order based couple of inputs and checks during MRP run .Basically , it depends on following
In MRP exectuion you should keep : Procesisng Indicator : NETPL: The system only plans materials that have undergone a change that is relevant to the planning run within the period which you defined as the planning horizon. The system sets the net change planning horizon indicator automatically for these materials
Planning Mode : 3-Delete and Re-create Planning
It also depend on following set up and you need to analysie that :
1.Planning Time Fence : based on the PTF , there will not be any automatic changes relevent for MRP
2.MRP Type : PD , it will adoped normal planning and it will not re-schedule order proposal automatically .In you case can use P1-Automatic Firming and Re-schedule Out Of Order Proposal based planning time Fence
3.Keep your Planning Horzon more than the Highest Material Lead Time in Material Master MRP2 View
Please check and revert

MRP Rescheduling Error with quota arrangement

Hi i have a problem when using a Quota arrangement in MRP. When i use NME59N to order,the system proposes to bring the first vendor 100% for a month and then the next supplier for a minimal share the following month. the quota is available clearly in PR'S but when converted to PO'S the rescheduling takes the first po as a referrece instead the assigned PR'S.Can any one help me sorting out this?

When you run ME59N you will convert the requisitions inot POs (the same requisitions that you see in MD04). The vendor assignment is not modified by ME59N. This is already done by the Quota when the MRP runs.
In ME59N you can control if each requisition will be converted into a single PO, if multiple requisitions are going to be joined and converted into a single PO, etc.
I am still not sure if your problem is with ME59N or what you don't like is how the vendor is assigned (considering the Quota) when the MRP is executed? If you see in MD04, is the assignment correct? if the vendor assignment that you see in MD04 is not what you want.. then we should find a solution working with the Quota and with the MRP paramenters. Is your problem the vendor assignment that you see in MD04?
