Exception message in MRP

Hi,
I hd created BOM for header mateial with all low level code. After execution of MRP run system generate one exception message no 52-No BOM selected.
What is the mean of this message, for same already BOM is exist so why the system is generating message.
Regards
Rajesh

Rajesh,
The possible reason are,
1. BOM is not valid for the date on which BOM explosion happened. Probably the BOM was created valid from today, but the requirement is in Past.
2. Planned order qty is not within the lotsize range of the BOM.
3. Look for BOM status and Usage.

What table are Exception Messages in MRP stored?

The requirement is to develop an error report from an MRP run to capture the exception messages along with the selection groups.
Ex:Selection Gr 2; Exception Message 15: Reschedules In.
I am unable to track where exactly the exception messages are stored after an MRP run. Any suggestions as to how to go about this requirement.
Thank You.

You can basically get a list of all tables MD06 (colelctive MRP list) uses to fetch data. GO to tran se30. Under Measurement restrictions click new and in Duration/Type tab select none. Go back to se30 main screen enter tran MD06 and execute. It will take you to MD06, run it with any material and go back to se30 screen. At the botton select evaluate and on the evaluation screen select "Data base hit list" or F6. That will give a list of all tables accessed by MD06. SO basically you will know all the tables that were filled during last MRP run.

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,
Jinen

Hello
I have just created a new WIKI about the rescheduling check on MRP.

Different Exception messages in MRP list & Stock Requirement List

Hello Experts,
When I run MRP and then look at the stock Requirement List & MRP list for the same material, I see different exception messages in these list.
I noticed that any of the exception messages in Exception group "7 - Exception during rescheduling" (ie, 10-reschedule in; 15-Reschedule Out; 20-cancel process; 30-plan process according to schedule) is not appearing in the stock requirement list even though they appear in the MRP list.
Does any configuration affect what message group can appear in Stock Requirement List & MRP list?
Please advice.
Regards
Tom

Hi Tom,
For exception message - 62, just do the below checks -
Some of the reasons as to why you may find this exception message is because the backward scheduling can drive the start date in the past so far that:
- there is no valid BOM as of that date
- one or more of the work centers are not valid on that date
- there is no valid factory calendar on that date
Check the scheduling formulas in your work centers that are set up, and/or to specify for the material master a fixed lot or a max lot size so that planned orders result with realistic lot sizes.
Also you can set up MRP to only run on basic dates for your overall run, and to follow up with an MRP run which generates capacity planning only within the planning horizon, such as NETPL. You would need to configure the planning horizon so that it specifies a time frame over which capacity planning is to be done.
Also check the note : 88505 - Planned order upload generates exception message 62
In short, do a thorough check of the parameters maintained to ensure there is no inconsistency in the master data.
Check & revert.

Vivek

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.

Table of mrp exception messages

Dear guru ,
which is the table where i can find the exception messages of mrp for every material ?
Thanks in advance.

Jesus & Cris,
MRP detailed lists, including all exception messages, are stored in transparent table MDKP and cluster table MDTC.
Unfortunately gentlemen, the data in MDTC is not directly readable by a simple query. MD06 is usually used to create lists of specific exceptions. If this transaction is not suitable for your needs, an ABAPer could write a report for you, as suggested by Rupesh in the earlier post.

User exit/BAdI to manipulate display (MRP) Exception messages

Dear,
I wonder if there is a user exit/BAdI or implicit enhancement with which I can manipulate the display (or not) of (MRP) Exception messages in MD04/MD07.
In customizing of the Exception messages (table V458A) there is the indicator No exception message (V485A-ASNOT) but if this indicator is ticked, the Exception message is never displayed;
My client wants this message only not to be displayed in case the Material is of a certain Material group.
In all other cases, the Exception message should be displayed.
Thanks for any clues!
Kind regards,
Bart

Hi Bart
There is no exit or BAdI to manipulate exception messages in MRP. See the following note:
1697703
MD04/MD05: Change or create new exception messages
You can find a list of the most relevant BAdIs available for MRP on the following document:

Is there a report to track the exception messages after a MRP run ?

We have a scenario at our client site where MRP run is not optimized to the fullest.
The planners are not trained on how to interpret those exception messages.
They are not trained on how to reschedule / expedite planned orders resulting from an MRP run.
Is there a report out in SAP that keeps track of
1) History of number of exception messages by type ( Expedite/Reschedule/Cancel)
2) History of number of exception messages that were acted on or ignored by the planner.
This is to create metrics on the usage of MRP exception reports by planners.
Appreciate your inputs..

Hi
The exception messages are dynamic and time dependant. You cannot have history of exception message.. If your user is feeling difficult to use standard MRP reports. Create a new report using a function module MD_STOCK_REQUIREMENTS_LIST_API
It gives all MRP data including exception messages.

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 - want to create query for Exception message number (MD04)

Dear all MM kings
consider i had one purchase against xxxx material , if i go to MD04 In Exception message number column i got massage number 20 Cancel process, now i want to know how many purchase order exist in system having the Exception message number 20
i want to define query for Exception message number 20
is there any way to do the same

Hi,
There are links on the first thread on this MM board that describe how to produce a query.
But if you have not done this before and have no ABAP experience, you might find it a bit tricky.
You need someone to find the tabkle that stores the MRP lists and see if this contains the exception message, first.
the structure I gave you is probably built dynamically by the program and so may not be available for a query.
One simpler option is to use the "Collective access" tab in MD04. here you can enter an MRP controller etc. and get a list of materials. You can then find out which of the 8 numbered columns contains the exception message 20 and then sort the list in this sequence (the exception messages are linked to one of the columns and this can be different in every implementation and so I can't tell you which one it is)
This will not just get the "20" messages unless they have been configured to use a separate column, but at least it is avail;able now without config and may be enough for your purposes.

Exception Error Message on MRP Type

Hi Gurus,
Currently system does not set exception message. Any purchase requisition should generate an exception message.
How will we configure in the system?
Thanks in Advance.
Neo.

MRP exception messages need no configuration. They have a predefined logic, like for example if the delivery date is past due.
If you configure and use MRP properly, then system is issuing messages for all the planning relevant situations.

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.
