Repetative Manufacturing - Activity Backflush

Hi All,
I am doing MFBF I need to have a constant 1 in Qty to confirm and Planned to confirm cells , However the qty of the Backflush can be changed to anything.
Please guide me for the releated settings for the same.
Matter is Uregent.

Dear Joshi,
You can make the default settings as activity backflush and the plant,but you can not make the
quantity also a default one in MFBF screen.
Say selecvt the radio button for activity backflush and also the plant and click on initial screen icon in
the top,come out and whenever you enter MFBF screen you will be seeing the radio button selected for
activity backflush.
But you can try to create a transaction variant and use that in MFBF,if you dont wish to enter the
quantities every time,but I would suggest to use only initial screen icon option.
Check and revert back.

REM Activity Backflush

Hi All,
In repetetive manufacturing scenario when do the backflush for materials and activities I can see the material GI/GR through the movement type I have defined in REM profile where can I see what all re the activities that are backflushed.
Thanks and Regards
Ramana

Hi
You can see the Activity posted for the production Version in Table AFRU by picking the RUECK and RMZHL for the corrsponding version of material for which you have posted Activities.or you can see assembly bacflush and activity backflush in t code KRMI for the date and material
Hope It will Help you

Error when do Activity Backflush

Hi Experts,
When i am trying to do Activity backflush (REM) in open period its giving following error
Error determining the cost estimate
Message no. RM078.
More information:
        - For that material, I created Product Cost Collector, but I dont want to run Cost Estimate. I test in Client 300(Pre Prodction) still ok, but fail in client 400(Production).
        - Assemply Backflush and Component Backflush still be OK.
        - In REM profile not set Post Activity
Please help me.
Best Regards.
Tony

Dear,
Error RM078 occurs if services should be posted according to preliminary costing (setting in the repetitive manufacturing profile OPS2 is there)
Prerequisite:
1. You did not activate 'Post services' in the repetitive manufacturing profile.
2. You did not create any version-specific cost estimate (Preliminary costing) for the product cost collector.
Remark: in the repetitive manufacturing profile, it is parameter "Cost estimate" with the values
   '' : Backflush using std cost estimate data for all versions
   '1': Backflush using version-specific cost estimate data.
Please refer the OSS note 137459 - RM078: Error determining the cost estimate.

Repetative manufacturing vs discrete manufacturing?

hi
what is the difference between repetative manufacturing and discrete manufacturing
regards
sanjay kumar nanda

Basic difference is in REM, a same product will be manufactured for a long period of time...
In discrete,the products will vary frequently....
REM:prodcut dont change frequently
components are staged at lines periodically
Backflushing
COst control is period based
Discrete:Product chane freq
COmponents are issued with ref to order
COnfirmation
COst control is order based,
hope this helps...

Maping of material in repetative manufacturing

Dear Guru
Plz suggest how to map the material in repetative manufacturing
scenario:
input material : A, B AND C
Output material: x y and z
how to map in backflush(mfbf) . In one shot we want to enter the input and output material . We have to enter actual consumption of input and output material

Dear Ank,
In the confirmation screen MFBF you can confirm at a time only for a single material and for this product the corresponding
components can be posted which will be carried out for 131 & 261 movement for GR & GI respectively.
It's not possible to make GR for more than one product at time,but however using MF42N it's possible to carryout collective
backflush for a set of products based on the input given.
now check with this and revert back with your queries.

Activity backflushing in REM

Hi,
We follow repetitive manufacturing for FERT materials with Prod version, Rate routing and Product cost Collector. In our REM profile for posting activities we have assigned the option 'Using data from prem. costing for prod. cost collector'. We are saving the preliminary cost estimate for prod cost collector periodically(including the activity cost). In this case while doing assembly backflushing for the FERT material the activities are not posted as per the values defined in the rate routing. Please let me know the reason for the same.
Regards,
Ravi Kumar C.

Dear Ravi Kumar,
I'm not meaning about cost calculation,What I mean to say is if there's any change in BOM
component's are quantities or rate routing operation details the first step you have to do is in KKF6N-->
for that material,plant,production version goto change mode and click on costing button and save the
datas,so that the latest changes are taken up for the preliminary costing.
Because based on this only your confirmation either assembly or component or activity backflush is
carried out.
So again in activity backflushing you have 2 options for the radio button selection,
1. No planned activities from routing
2.Fetch Planned activities from routing(this picks the data from your routing)
The options No planned activities from routing and Fetch planned activities from routing provide you with
three different ways of entering activity consumption or activity scrap.
1. Fetch from the routing without planned activities.
2. Fetch the planned activities from the routing with specification of a reference quantity.
3. Fetch the planned activities from the routing without specification of a reference quantity.
If you select the option No planned activities from routing, you can use the "Process activities" option to
manually enter excess consumption or component scrap.
So check and revert back if there is any more queries.

Repetative manufacturing

Sir,
While carring out repetative manufacturing scenario what are the details to be mentioned in production version in mrp4 in planning data like detaile ,rate,rough cut planning once maitained it shows an warnig like the date doesnot math with alternate bom,detailed plannig ,rate planning,rough cut plannig. the company does have repetative manufacturing scenario, how to rectify the error ,kindly help
Thanks

Dear Sadanand,
1.Assign the REM profile in the MRP4 view of the material master and REM allowed indicator.
2.Assign the created rate routing and BOM inthe production version and also REM allowed indicator
inside the production version.
3.Rate routing can be created using CA21.
4.Assign the rate routing against detailed planning if you have assigned the routing selection id against
detailed planning in OPU5.Ensure your routing selection id is having the first priority to the rate routing.
5.Production versions can be created and modified using C223 or else using MM02 in MRP4 view.
Check and revert back.

Rework in Repetative Manufacturing

Good morning all,
Can anyone tell me or point me in the right direction, can we and how do we manage rework loops and rejects in the repetative manufacturing model?
Thanks in advance

Hello,
If you are working with 4.7 then Rework is possible in MFBF screen also.
If you declare some qty as rework , it will appear in FCOST screen.
While booking in mfbf you have to specify the version.
From FCOST you can book it as scrap OR good.
Here also you need to specify the version.
When you book rework , system will generate an entry in the background for RO
document.If you given back this rework to production area then again RI document will be ganarated in the system.
These documents can be seen in FCODOC.
We are extensively using REM in our plant.
Reward points if helpful

Repetative Manufacturing questions

Good day to everyone :o)
I have a question regarding Orders in Repetative manufacturing: -
The scheduling is done with planned orders if I am correct and the planning table (MF50) is normally used.
Is there a special order we can use for the shop floor control? that would be like a Producion/ Process Order?
I need to print out a BOM and Routing but whilst still using Repetative Manufacturing (I am sure I have seen like a "Work Order or something"
If any one could help me with this it would be much appreciated.
Kind regards

Hi,
With Repetitive planned orders we cannot have standard shop floor papers printed like discrete orders. Generaly repetitive orders do not have strict order quanitity control as it is available in Production orders. Routings generally do not vary for any repetitive order.
You can however print the following:
Production list: MF51
<b>If you want the task list (routing) to be printed along with the BoM use std transaction: CA51. Choose Display comp assignment</b>
Hope above is useful, if so reward points.
Regards
Ram

Capcity planning in Repetative Manufacturing

HI , Gurs can any body tell me how can I map this scenario in the Repetative Manufacturing
We have different product category which require different type of embossing on Tissue
Paper based on the product characteristics, so we have different Embosser Rolls which can be used on the multiple Production lines.
Kitchen towel
Name of Embosser      No of Embosser      Line      Priority to line     Product Group
KC Fan      1     LC30-LC31     LC-31     KC-Fista, Towel kc

LPC quilts      1     Lc23     L23     Morrion quilts,coop quilts
Scheduling of line LC-25 and LC 21 using Embosser KC Laman and LPC Laman
1)     Embosser KC leman can be used in the Two Production line Line LC 25, LC21 but LC 25 is the preferred line for Nordic KC product so if capacity is not available on LC 25 then it can be scheduled on the LC -21 .
2)     Embosser LPC leman can be used on the two Production line LC-21, LC25 but LC -21 is the Preferred line for the Lide, Norma gold car ford Product .
3)     One Embosser LPC Leman and Two KC leman can be used in the combination on the both Production line in such A that one only one change over is possible in one Production line in one month and when ever change over is happening 24 hours gap between should be on the line.
4)     Maximum possible combination which can be used for scheduling of Planned order will be six, because three Embosser is being used in the two production line.
Scheduling of line LC-23 using Embosser KC Quilts and LPC   quilts.
5)     Embosser KC quilts can be used in the one Production Line LC 23 for scheduling the Plnned order .
6)     Embosser LPC quilts can also be used on the Production line LC-23 for scheduling Planned order .
7)     One Embosser LPC quilts and one Emboser KC quilts can be used in the combination on the Production line in such a that one only one change over is possible in one Production line in one month and when ever change over is happening 24 hours gap between should be on the line.
Scheduling of line LC-31 and LC -30 using Embosser KC Fan and CCD, WC.
8)     Embosser KC Fan can be used in the Two Production line Line LC 31, LC30 but LC 31 is the preferred line for KC Fiesta product so if capacity is not available on LC 31 then it can be scheduled on the LC -30 .
9)     Embosser CCD can be used on the two Production line LC-30, LC31 but LC -30 is the preferred line for the Lide. .
10)     Embosser WC can be used on the two Production line LC-30, LC31 but LC -31 is the Preferred line for the Lide
11)     One Embosser LPC Leman and Two KC leman can be used in the combination on the both Production line in such A that one only one change over is possible in one Production line in one month and when ever change over is happening 24 hours gap between should be on the line.
12)     Maximum possible combination which can be used for scheduling of Planned order will be nine, because three Embosser is being used in the three production line.

Dear,
Please note that REM with minimum requirement can be used.
You can define production version for each production line and preferred production line will have the the first PV.
You can perfom the capacity planning in MF50 depending on the production line load.
please come back if you need more help

Activity backflush

Dear All
I am doing the activity backflush in MFBF,system posted the activity here my requirement is i want to see the activity backflush cost alone.When i am seeing the standard reports system showing the acrivity cost incluing assemvly backflush,i want activity backflush cost alone
Regards
Srinivasan.P

Dear Srinivasan,
You can get the activity backflushed logs in MF12 and after executing check for Processing type for
backflush - A : Only activity posting.
For this date you can see the costs in the product cost collector in KKF6N,Either by changing the
layout or double clicking on the individual line item for activity.

Difference between repetative manufacturing and discreate manufacturing

Hi,
Guru's
What is the difference between repetative manufacturing and discreate manufacturing in product costing.

Dear Manish,
Repetitive Manufacturing
In repetitive manufacturing, master plans are typically created on a period and quantity basis (reduction in individual lot and
order-specific processing). A quantity of one product is manufactured over a certain period. The product is processed in a constant flow and interim products are generally not stocked. In repetitive manufacturing, you usually find that the effort required for production control is significantly less than is required for single lot and order-based production control and the recording of actual data is kept simpler. Repetitive manufacturing can be used for various industries, such as the
consumer packaged goods industry, the electronic industry, packaging industry, for example.
You can use Repetitive Manufacturing purely for make-to-stock production, or in a sales order-oriented environment, such as found in the automotive industry.
Discrete Manufacturing
Discrete manufacturing is characterized by requirements that occur on an irregular basis and a workshop-oriented process.
The Discrete Manufacturing scenario can be used in different variants, production by lot size, make-to-order production and assembly processing. The variants differ mainly in the type of planning conducted before-hand and in the relation to the sales order. Production by lot size is identified by the grouping of requirements into lots during requirements planning, and by planning with existing basic data. Production by lot size is independent of a particular sales order. Make-to-order production describes the production of a material with reference to a particular sales order. The manufactured quantities are managed, in terms of stock, directly for the individual sales order. They cannot be exchanged with the stock of other sales orders. Starting from the sales order, single-item planning can be allowed as far down the bill of material (BOM) structure as you like. Assemblies and
components can also be procured for the sales order that generates the requirements, and managed in stock for this sales order. If the product is a configurable product, the system chooses a variant for the customer based on the characteristics that he or she selects. A sales order BOM can then be generated for the sales order. This BOM is used to produce the product.
Assembly processing is a form of make-to-order production, in which the production order (assembly order) is created together with the sales order. In assembly processing the components for the product have, in general, already been produced. They only need to be assembled. The advantage of assembly processing is that an availability check is carried out for the components when you create the sales order. This increases the reliability with which dates can be confirmed
considerably. Changes to the sales order are automatically also made in the production order and vice-versa.
And also you can follow the below link to know more about REPITITIVE MANUFACTURING its a pdf document from help.sap.com
http://help.sap.com/printdocu/core/print46c/en/data/pdf/PPREM/PPREM.pdf
One More Example
Repetive is usually a continuos flow, good example is making 5000 tv dinners you know how long it takes to make qty1 very little defects or fall out and you always have everything on hand to start the run, you may also make the same run 2-3 times per month so a cost collector is ok all cost go to top level.
Discreet, You do have falls out reworks and move into production missing materials, long lead time its essential to know what and where it is at in production, cost may vary a little but each production order will be costed independantly for review.

Difference between PP(discrete ) and PP-PI and repetative manufacturing

Dear all
1) What is the difference between PP(discrete ) , PP-PI and repetative manufacturing ?
2) In terms of SAP implementating how to choose out of these ?
3)What is the difference in terms of SAP for all three?
regards ,
Vishwas.K
Edited by: vishwas.k on Oct 9, 2010 3:31 PM

Dear
There are lot good threads and wiki abailable for this generic topic .
These are diffrences between REM/Discreate/ and Process manufacturing.
REM:
Production is based on the planned orders.
Planning and manufacturing is based on period wise.
Normally single products being manufactured for a longer period of time.
Normally production are carried out on a single production line (repetitively).
Product costing and settlement is done through product cost collector.
Planned orders are known as Run schedule quantities. Means quantity which is being manufactured in a certain period.
Planned orders are sufficient to carry out production at shop floor area.
Master data includes production version, product cost collector and rate routing.
Materials will be issued anonymously to production lines means without reference to planned orders.
Discreate:
Production based on the production orders
Planning and manufacturing depends on production orders.
Products changed frequently.
Production is carried out on different production lines (scattered- discrete).
Product costing and settlement is done through production orders.
Planned orders are stock type later converted into production orders.
Production orders are required.
Production version and product cost collector are not mandatory.
Materials will be issued always with reference to production orders.
Master Data includes Routings and BOMs.
PROCESS:
1) Batch Oriented process manufacturing.
2) Process order based manufacturing.you copy the process described in a master recipe and adjust it to the actual production run.
3) It is primarily designed for the chemical, pharmaceutical, food and beverage industries as well as the batch-oriented electronics industry.
4)The integrated planning of production, waste disposal, and transport activities within a plant.
5) Master Data includes Master Recipes and resources.
6) Process Management:In this area, you coordinate the communication between PP-PI and process control during the execution of a process order.
Best will be refer SAP help material .Appereciate if you carry out forum searh on the same .

Reversing activity backflush

Hi,
Activity is posted thru activity backflush and reversed by MF41. But it is very difficult to understand which document to be reversed and what values it has.
How can we find the details of document log and where can we see the parameters/ values we posted in activity backflush . before we can reverse it.
Regards
ShankarR

HI
You can chekc table BLPP and BLPK for the document log and items also you can check table AFRU for the activities which you have confirmed and also in t code KRMI .
Check and revert
