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

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.

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.

Exception message 10 and safety stock

Hello
When I have a ressource in the past (we have this case), and if the safety stock is not complet, the exception message is "10" (reschedulling in) without date.
Normaly the result should be exception message "15" (rescheduling out) with a date.
Why have I an exception message "10" without date ?
Is it the custo, but I found nothing ?

Hi Christian,
I've seen this myself, and believe that it happens only if you allow start in the past and have got insufficient coverage for safety stock.
I guess it doesn't have a date because of the start in the past, which will set availability date even today. Try to change the "start in the past" indicator, and see what happens.

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.

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:

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.

Creation of Exceptional messages

Dear All,
In the Stock/Requirements list, I want to create an exceptional message for the following Stock Transport scenario.
Supplying plant is 1000, Receiving Plant is 1100.
In the Receiving Plant 1100 there is a Stock transport PO with Receipt Date 01.06.09.
For the the same PO, there is an MRP element 'Ord DS' in the supplying plant 1000 with Requirement date 01.06.2009.
Since the Requirement date is in the past at the supplying plant 1000, system should give an exceptional message .
Please guide me how to generate the exceptional message.
Thanks & Regards
Bala

Hi
Steps to create Exceptional massages
1) Define Check Exception Group Texts : using path SPRO > Production > Material Requirements Planning > Evaluation > Exception Messages
2) Create new messages in Table T458A (Exception Messages in Material Requirements Planning) and Set Priority for EM
3) Check the Messages in SPRO > Define and Group Exception Messages

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 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 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 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.

Stock Requirements List

Friends,
When we are using the t-code MD04 to generate the stock requirements list for a material, it is throwing an error "Please maintain version in table T009". Table T009 is the table for fiscal year variants. There are no versions to be maintained there. Also, the fiscal year variant that is assigned to our company code is maintained there. Further, the stock requirement list is being generated for other materials (even those marked for deletion).
Please advise on how to solve this issue.
Thanks & Regards,

Friends,
The problem was with the material master wherein a different fiscal year variant was maintained in the MRP view (different from the one attached to the company code). Changing the material master has solved this problem.
