MRP Exception 20

Hi there
In the Stock Requirements List, some of my parts have more than one PO and an additional Requisition. The POs have the exception message '20 - Cancel Process'. Seemingly MRP creates more Reqs despite the fact that a PO exists already.
No changes were made to the Reorder point, Max Stock Levels or any MRP Parameters.
What does the Exception 20 mean and how does MRP react to it? And should these POs be deleted from the ERP system?
Your urgent assistance will be appreciated.
Thanks.
Abigail.

Hi,
20 - Cancel process means , planned order or proposal created without Independent requirement.
ie, Excess proposal more than demand.
To delete the excess proposal, run MRP by MD02 by selecting planning mode - *delete and recreate data * in the initial screen of planning run for that header material.

Dharma

MRP exception message 64 and planning strategy group 52

Hi Gurus,
I have done extensive search online in the forum to find the route cause why we are getting MRP exception message 64 for a specific material in one of our plants. This exception message does not occur for the same materials which is also produced in another plant.
I was just wondering whether the planning strategy group of 52 in MRP 3 view would have any effect on the frequent occurrence of exception message 64. I know that the 64 message occurs when the routing time is higher than the in house production time. If that's the case where to look for in routing to correct this, apart from this do we need to look at work centers and other details. I'm not a PP person but still was curious to know see if i could take a shot at it.
Also the MRP settings that we follow in the plant where this problem does not occur is NETCH, Create PR - 2, Schedule lines - 3, create MRP list - 1, Planning mode - 3, scheduling -2
in the plant where the 64 message occurs quite often is Netch, Create PR -2, Schedule lines - 3, create MRP list - 1, planning mode - 1, Schdeduliing - 1
I was thinking do MRP settings and planning strategy group would have any impact on why we are getting the 64 wexception message
Because of this 63 exception message, the downstream components are getting wrong signals.
Thanks
Ravi

Hello Ravi
Generallt, exception message "64 - Production finish after order finish" is triggered when the order start date is in the past and system automatically changes to forward scheduling to calculate the finish date.
Note 1913017 explains how the order basic date is calculated and adjusted in case of forward scheduling, however, you are using strategy 52 and this is a very special scenario, whever VP planned orders are generated.
The VP planned orders will always be adjusted to the requirements date even if the requirements date is in the past. This is a special feature in the planning segment, since these orders are only kind of 'virtual' planned orders. These orders only have to provide the demand requirements for the components in time.
Therefore, there is a relationship between strategy 52 (VP planned order) and the exception message observed.

MRP Exception Message 26: Excess stock in individual segment

We would like to modify the logic relating to MRP Exception Message 26: Excess stock in individual segment to allow for a material-specific tolerance threshold, within which no exception would be generated. An alternate approach might be to deactivate message 26 and create a new custom exception that accomplishes the same thing.
The reason is that we fabricate and procure a large number of materials in a Make-To-Order environment, with some planned scrap at multiple levels of sub-assembly. The result is that we often have small residual quantities of components & sub-assemblies in sales order stock when the project is complete. Some of these may be useful on future projects so we want them to remain in stock, but we donu2019t want them to continually generate exception messages that distract our planners from the exceptions that truly need attention.
I have tried setting up a storage location that is excluded from MRP, and this works only if the material is in General Stock, but not if it is in Sales Order Stock.
If anyone knows of a way to either set up an allowed tolerance, or exclude a sales order segment from MRP, please let me know.

DB49,
I have previously suggested just what you have indicated (ie. to move the parts back to unrestricted geneeral use stock). My company's objection is that the materials were either produced or procured for that original sales order and that the costs for these materials are in that sales order as well. Using a 411E transfer posting will not only move the stock, but also the cost (as if we are buying it back from the sales order). Since there is no guarantee that we will be able to sell it again, our accounting department will not allow us to do this.
So the bottom line is:
We do want to retain visibility to these stocks.
We don't want the cost for these stocks back on our books
If the opportunity presents itself, we want to move them to any future sales order for the same material.
We don't want the hundreds of exception messages for "excess stock in individual segment"
However we do want to see this message for actively planning sales orders that may have too much stock
There may be no way to get this, but that is the goal.

MRP Exception message for Excess production quantity

Originally, there is a demand for a common item material A 1500
One work order is opened for this grouped demand
Grouped Demand: 1500
Work Order QTy: 1500
Due to a drop in demand, the demand fall to 1200
At this time, will any MRP exception raise to suggest the order to reduce the scheduled quantity to 1200?
If there is way to do so, what should I set to achieve this requirement?

I just afraid additional demand would raise by setting this coverage.
I tried to define a range of coverage profile in the system with min:0 target:0 and max:1
I set a material to use this profile and run a MRP with my above case.
But still No exception message was suggested for the case.
Is there something I am missing out?
Anyway, thanks you for your suggest.

Working with MRP Exception Message

Hi Team,
In MD04, i am getting exception messages like below.
20 - Cancel the Process
15 - Postpone the process
10 - Bring Process Forward
I have already read the SDN postings and also the below link.
What is rescheduling and how does it work - ERP Manufacturing (PP) - SCN Wiki
But question is, Instead of MRP raises this exception message like "10 - Bring Process forward". This exception message proposes new start date for the planned order.
Q1: Instead of raises this as exception message, during MRP run, the planned order start date can be directly modified by the system know?
Q2: On daily basis, How to act on this MD04 exception messages? How the MRP Controller should act on this exception messages? Should the planner need to modify the planned order dates manually as proposed by the exception message?
Q3: Do w have any mass transaction to act on this exception message?
Thanks

But question is, Instead of MRP raises this exception message like "10 - Bring Process forward". This exception message proposes new start date for the planned order.
Exception message '10' is raised to 'firmed' receipts - not planned receipts. MRP cannot change the firmed receipts (exception - roll-forward periods), hence adjustment in case of this message is out of the question. Rest assured, the planning run does adjust the receipt as much as possible.
Q1: Instead of raises this as exception message, during MRP run, the planned order start date can be directly modified by the system know?
Have you seen exception message '10' to a planned order which is not fixed/firmed? System adjusts when possible.
Q2: On daily basis, How to act on this MD04 exception messages? How the MRP Controller should act on this exception messages? Should the planner need to modify the planned order dates manually as proposed by the exception message?
This may involve many manual decision from the planners and should not be automated. You can help out a planner through reports, but the decision should not be taken automatically.
If you find it interesting you can go through responses from Dogboy 49 and myself in the threads shared below:
Handling of MRP Exception Message
md04 exception
Q3: Do w have any mass transaction to act on this exception message?
No, you may think of developing something using BAPI_MATERIAL_STOCK_REQ_LIST or MD_STOCK_REQUIREMENTS_LIST_API function modules and providing hyperlinks to the users so that they can directly be inside the corresponding change transaction according to the MRP element.
However, 10, 20 and 15 all of these three exception messages come due to rescheduling for the firmed receipt elements. In MD07 you can get a collective overview of number of these messages in the exception group 07 (standard).
Best Regards.

MRP Exception Messages - Best practices

Dear colleagues,
I am currently dealing with a large SAP installation where system is already live in 50+ countries and the number of manufacturing plants are in hundreds. MRP generates exception messages but the volume is significantly high. Planners have lost faith in these messages thus the client is not getting the full benefit of reacting to MRP exceptions.
Have any of you dealt with similar business situations? If yes, what best practices and what system design have you put in place to simplify the process of resolving exception messages.
Thanks,
PKV

Hello Pavan,
MD06 should be the planner's best friend as it helps him be on top of all the future expected shortfalls, talk to production schedulers or Vendors to bring material on time for production/deliver to customer.
Best way to handle exception messages in a plant is to divide it by MRP controllers, procurement types external or internal.
Planners have to analyse MD06 after every MRP run if possible. Atleast once a week go through their MD06.
However as per my experience most places the material master planning data is not as clean as the planners would like to have. But MD06 offers them an opportunity to update the material master as per their choice. ie planners can change planned delivery time, mrp lot size, mrp type etc..
You may have to find out why the planners have lost faith in MRP messages. System(MRP) can give you a good result only if master data is good.
Hope this helps.
Thanks,
Ram

MRP Exception messages difference

Hi PP Gurus
I need to understand the exact difference between few exception messages
MRP Exception message 6 - Start date of supply proposal is in past
MRP Exception message 7 - Finish date of supply proposal is in past
Query : Does it means that if start date is in past & finish date is in future , then only EM6 will appear .If both are in past , then EM7 will appear ???
MRP Exception message 10 - This is meant for Rescheduling IN i.e. if the supply proposal finish date is later than reqt date
MRP Exception message 15 - This is meant for Rescheduling OUT in i.e. if the supply proposal finish date is eariler than reqt date
MRP Exception message 30 - Plan process according to schedule i.e. pull or push the supply proposal as per reqd date
It looks to me that
EM30 is same as EM10 & EM15 since the former also suggests to pull or push as the latter two does .Then what is the exact difference between these
rgds
sandeep

1- I'm not sure, but could be.
2- Difference between 10, 15 and 30 is that 10 and 15 are for firmed elements (like production order or purchase order); 30 is for planned order (or other NOT FIRMED element) that cannot be properly planned because of LT problems.

Update MRP Exception Messages...in Oracle Database

Hi All,
I am working on MRP Exception Messages.
I am using the BAPI_MATERIAL_MRP_LIST for my MRP Messages.
For the above BAPI The Inputs are 1.Material Number 2. Plant.
I have the Plant and Material numbers (57,000 i inserted using BAPI_MATERIAL_GETLIST) Tables With Data in my Oracle Database.
I would like to update the MRP Messages Table in in my Oracle Database.
My logic is I took the plant numbers and put into the repeater and the same Material too. I am giving linking the both to BAPI inputs,material and Plant. Is it right what I am going?
Can you give some ideas how to do it.
Thanks
R M

I think this is a duplicate of your other MRP Exception Message. Please close this one since the other one is receiving all the responses.

MRP exception handling for planning strategy 52

Hi All,
How to handing MRP exception in Mass? For example, header material having two sub assembly and 3 raw materials in it's BOM. As per planning strategy 52, we maintain PIR for finished part, if we run MRP planning will be generated with respect to Planned Independent Requirement(PIR). Now, the problem is the higher/upper level material planing date is lower than low level material, It means Semi finished material(SF2) planning date is for example ( 15 june 2014) at the same time another lower level semi finished material (SF1) planning date is (18 june 2014). In this case without completing SF1, we can't produce SF2 because SF1 is an component of SF2. In the same way, system will propose the planning info for all raw material/semi finished. How we will handle this exception in mass since we using more materials in shop floor.Hence, it's really hard to planner to adjust the planing date for each and every material wise. How to handle/adjust this MRP exception? How to make system to calculate dependent materials availability to calculate next level material's planning date (start,end)? We understand that we have to maintain proper master information like in-house production days, planned delivery date, Gr processing date etc., to get planning information. Apart from that how we handle or to get without this kind of exceptional message? Please suggest
Thanks

AKS,
There is absolutely nothing wrong with having exception messages. Expecting to be able to perform some mass transaction that will magically make all messages "go away" is unreasonable. In any real life business, there will be new exception messages with every MRP run - sometimes thousands of them.
These messages indicate that there is something the matter with the plan; but they don't really tell you what is the best way to fix the plan. There may not be an easy way to fix this plan, it may actually require having your planners examine each PIR, trace down the BOM, and determine what is the best solution for that PIR. Once you have decided what is wrong with your plan, then ask me what mass changes are available to fix THAT problem.
Now, to your question. If you want all the dates to line up, then allow dates in the past. Although this solution doesn't give you results that are any more realistic than your current solution, you will eliminate most of the exception message 10's; and, if all your master data is correct, most of the supply and demand dates should line up. The messages will be replaced with a boatload of "new, and start date in the past" or similar. You can allow MRP to create procurement proposals with start dates in the past by changing the appropriate settings in OPPQ and/or OPPR. Also affected by scheduling parameters found in OPU5 and OPU3.
This is a business decision. Some planners prefer not to allow dates in the past. Others just the opposite. You (or the client, if you are a consultant) have to decide which is best for your company.

Regrouping of MRP exception messages

Hi Gurus,
Can anybody please help me with this issue. The business has requested to regroup the exception messages arising in MD04/MD06. Currently there are 8 selection groups into which all the MRP exception messages are put in. The business wants to move some messages in to different selection groups. Can anybody please let me know what are the implications of doing this? The reason the business has asked for this is that they feel that there are so many unused selection groups and they want to organize the messages as per the title/name. for example Reschedule in (message no 10) and reschedule out (message no 15), they want to separate these into two groups. Once group called expedite which will contain message 10 and anothet group called deexpedite which will contain message 15. sinmilarly for other messages. Please throw some light on this. Help is greatly appreciated.
Thanks
Anusha

Dear,
There is no the implications of doing this but note that most of exception message functionallity is hard-coded in MRP.
OMD3 and OM0L are the places you can make the possible changes.
Or you need to go for develpment with MD_STOCK_REQUIREMENTS_LIST_API
Use the BAPI_MATERIAL_MRP_LIST where AUSSL Exception message key. You will get all details

MRP exception message

Hi,
How to interpret the MRP exception messages in MD06?
1.what is the meaning of Stock days supply field showing 999,9- (meaning of 999,9-)
2.what is the meaning of 1st receipt day supply & 2nd RDS
3.Exception message group 3 showing the value 19 (In message group 3 there is no 19)
Can you please elaborate the each one in detail?
Thanks and Regards,
Vairavan

Hi,
The main difference would be what you consider as available for the calculation. You can configure in OMIL.
Regards,
Vivek
Pasting SAP help, which explains it quite clearly:
The receipt days' supply indicates how many days a material will last. The system takes current plant stock and specific, predefined receipts into account when calculating the receipt days' supply.
You can define two receipt days' supplies.This enables you to instruct the system to take the less binding receipt elements into account for the first receipt days' supply, and to take only the binding receipt elements (such as production orders and shipping notifications) into account for the second days' supply.
Additionally, in Customizing for MRP, you can use the safety stock indicator to define whether the number of days refers to the safety stock or the actual physical stock.
If the number of days is based on the safety stock, which is set in the standard settings, the system calculates the number of days until the stock level falls below the safety stock level. If the number of days is based on the physical stock level, the system calculates the number of days until the stock level falls below 0.
Material with critical ranges of coverage are indicated by red traffic lights in the MRP list and the stock/requirements list. You can define how many days are considered to be critical.

MRP Exception List

Hello,
I want to view exceptions generated in MRP by multiple MRP controllers.
Transaction MDLD - Print MRP LIst and Transaction MD45 show only for 1 MRP controller.
Is there any report which can show me the MRP exceptions for multiple MRP controllers which I can specify in the report parameter?
Thanks,
Sincerely,
Ketan

Hi,
You can find it in MD05/MD06.
Go to collective access Select plant and restrict selection by Exception Groups and enter.

MRP exception message configuration in SPRO

Hi all,
Please advise where we can do configuration settings of exception message in SPRO.

Please check the first link of my post. Path and usefull info is mentioned there:
MRP exception message:
spro -> pp -> mrp -> evaluation -> exception messages -> define & group exception messages.
Define and Group Exception Messages
In this step, you define the following parameters for exception messages:
Whether exception messages are displayed for particular exception situations
If a particular exception message is not relevant to your company, select the field No exception message. In the planning run, this exception message is then no longer created for this situation.
The priority in which exception messages are to be displayed
If several exception messages exist for one MRP element, you can assign priorities to determine which exception message is to be displayed in the MRP evaluations. The system always displays the exception message with the highest priority directly in the list. The exception message selected with the next highest priority can be displayed in the list by accessing the additional data.
You enter the priority of the exception messages in the field entitled Excep.mssge priority.
You can see the sequence of priorities by selecting the possible entries pushbutton on the input field. Thus, you can gain an overview of the previous sequence of the exception messages. The exception messages with the higher number also has higher priority.
How exception messages are grouped to exception groups
For the collective display of the MRP list and the stock/requirements list, as well as for all material lists created as a result of the single-item, multi-level planning run, exception messages are grouped into exception groups. In the standard system, a grouping exists that you can change, if necessary, in the field entitled Selection group. You can adapt the long text of the exception group in the step Check Exception Group Texts.
Depending on which exception messages MRP lists are created
In the initial screen of the planning run as well as in in the MRP group, you can define that the system is only to create an MRP list if certain exceptional situations exist (creation indicator "Create MRP list - depending on exception messages"). The exception messages that lead to the creation of the MRP list are selected in the field entitled Create MRP list.
Actions
1. Define whether the exception message is set.
2. Define the priority of the exception message.
3. If necessary, change the exception groups.
4. If necessary, select the exception for the creation of the MRP lists depending on the exception messages.

MRP Exception Massage

Hi Gurus,
Is it possible to Create MRP Exception Massage?
Actuly My client is looking for signals according to availbility of material in MD04.
Ex. I have requirement of 100 pc of material in next month (current stock is Zero). After MRP Run system will create purchase req/planned order for the same in the next month. According to scheduling if its purfect it will not create any exception massage and in MD04 it will show exception signal GREEN. But my client wants if current he has zero stock then system shood show RED exception signal.
In short if requierment is not getting covered by stock then system should show RED signal (Exclude safty stock)
Is there any solution for the same?
Expecting right guidence.
Tara

Hi Tara,
If I understand your requirement right, you look for a way to signal RED in MD06 whenever a requirement is not covered by existing stock.
For this you don't need a new exception message; just define the traffic light according to one of the 3 "DAYS SUPPLY" parameters.
Regards,
Mario
