Back flushing??
dear all,
I still confuse with back flushing, what is backflushing? and maybe you can give some example of backflushing process?
thank you
Dear Marufat,
Discrete Scenario:
Backflush is nothing but the automatic Good's issue of the material at the time of order confirmation.
It means consumption of the components has taken place in order to manufacture a product.
261 movements happens for the backflushed component's,for this you have to set the indicator either in
the material master (MRP 2 view or else in the work center or else in the routing).
If you are using Discrete concept means then this setting has to be made manually in any one of these fields and in the case of
REM scenario no need to set this indicator in either of the material master or else work center or else in rate routing.
If you are not going for backflush concept means then you have to issue the matertials to the order
manually using MB1A T Code.
REM scenario:
Again in REM scenario there are 3 types of backflush,
1.Assembly backflush(normally GR,GI and activities are posted - 131,261 and activites are posted) or vice versa like 132,262.
2.Component backflush(normally GI alone happens - 261/262 happens)
3.Activity backflush(only the operations are posted)
All these backflushes are performed using MFBF/MF42N.
Check and revert back.

Batch managment and back flush
Dears
Some of my raw material is batch managment activated now i want it to be as back flush
so pleae tell me what will be the imapct of doing the same'
How system automatically issue the raw material from the old date batches
AFHi Abu Fathima,
Batch Determination step as follows:
For that you have to do five important steps or features you have to know OK.
1) Batch number assignment: We use this function to assign a batch with a number that uniquely identifies it OK.
2) Batch Specf: To describe each batch uniquely using like Characteristics and characteristic The values. are allocated in the material master.
3) Batch status management: To indicate weather a batch is usable or unusable: We can set (a) Manually in the batch master record or at goods receipt and (b) Automatically in the usage dissension in quality management.
4) Batch Determination: We can use this function for various criteria to search for batches that are in stock (a) movement type: When posting goods issues (b) When combining suitable components for order types.
5) Where used list: The batch where used list shows the path of the batch from its procurement to its delivery to the customer.
6) Active Ingredient Management: This function is to administrate and process materials with active ingredients that are to be handled in batches OK.
Condition types: Say for x material if we want to determine the batch at the movement type/ plant/order type.
Access Sequence: It will checks weather the batch determination is done with movement type/ plant/ material &
order type/ plant/ material.
Strategy type: We will assign here condition type and Access sequence and as well we have to maintain Class type: 023
sort sequence, batch split
Batch Search Procedure: Here we will define the search procedure and using the condition type here OK.
Batch Search Procedure Allocation and Check Activation: Here we will assign the search procedure to the movement types and for order types as well
HERE THE BELOW FOLLOWING DATA WILL GIVE YOU RIGHT UNDERSTANDING OK:
a) It will looks for the search procedures.
b) It searches through the strategy types in the search procedures for a valid search strategy.
c) Characteristics from the selection class of the search strategy looks for batches with suitable specifications.
d) Then it will looks for weather the batches are available.
e) It sorts the batches that are available according to the sort rule from the search strategy.
f) Then the system selects a proposed quantity with proposed quantity from the search strategy.
Go -
> Logistic General -
> SPRO -
> Batch Management you can find every thing there it self.
Any questions revert me back please.

Failed to back flush in IDES 4.7 due to kp26 proplem

Back Flushing Vendor consigment Material in process order
Dear Experts,
I have a question Regarding Vendor consignment back flushing
while i am doing order confirmation system not proposing vendor name and in good movement tab
may i know what configuration or master data setup is missing
My requirment is i need to back flush vendor consginment material automatically
currently i need to manually choose the vendor while confiming the order
Thanks in advance
Rgrds
RajDear Experts,
I manage to use stock determination group for back flushing consignment material
it works fine system automatically picking up vendor as we do not have multiple vendors
now i have new issue
for instance
i have a RAW material A used in a Product A when i do confirmation system can able to do back flush with movement type 261 K
i am using same RAW material A used in product B and when i do confirmation system give me a error
as below
Pipeline/consignment movement posted without value
Message no. M7234Diagnosis
The system has determined a consignment/pipeline price of 0.00.
Possible reasons:
The system could not find any valid condition for the posting date in the consignment/pipeline info record.
A price of 0.00 was defined in the info record.
System Response
Depending on how the system is configured, the message can be either a warning or an error message.
A withdrawal from this consignment stock or from the pipeline will not create vendor liabilities. For materials with moving average price control, withdrawals are posted without value. For materials with standard price control, a price difference posting is carried out.
The message is also issued when materials are received into consignment stock, as the system must check whether a consignment price of zero is required.
Procedure
If you have authorization, check whether the conditions or the price has been defined correctly in the info record, if necessary. If there is a condition with a price other than zero, check whether the posting date of the movement lies within the condition's validity period.
Proceed
just wonder does any one have this issue
so strange i can issue to product A and not product B
Please help me if you have any problem

what is the concept of back flushing?
Hi,
Normally backflushing is set for raw materials / semi finished componenets. You can set the indicator in Material master MRP view 2 or in the Routing component assignment.
When you confirm the last operation of a order, then all the material componenet in the BOM (with backflush indicator) will be issued to the order using 261 mvmt type. So you don't have to do it manually using MIGO or using MB1B.
Thanks,

REM Back flush using firmed planned orders
Dear Gurus,
We are using REM manufacturing process in SAP , we are doing backflush for stage wise confirmation and final confirmation.while doing this we are not referring any planned orders as reference.
if we update new part numbers in BOM the system asking for the availbilty of that particular new part numbers but physically we are having old materials .
we want to consume that old materials how it possible in the MFBF t.code.
if any one please help me , if I firmed a planned order with quatity or date then sytem will ask the old materials instead of new one.
pls explain what is planned orders and their impact on MRP ?
how we can firmed that planned, if i firmed what is the impact duirng backflushing?.
Thanks & Regards
Suresh babu.s
WIN - IS.
SureshHi
please compare the process when you create the production order manually in Co01 instead of creating the production order by converting the planned order.
Here you are carrying out back flush with out refering the planned order.
It is like creating the production order manually.
In such case system will always look the BOM as of now.
It will not refer any of the planned order & the components there in.
If you want to consume the old parts instead of new parts , you can delete the new part numbers & add the old ones in MFBF. this will be allowed by system.
In this case you are back flushing with out reference to planned orders.System will not ask for old components at all whether planned order is firmed or not.
Once if planned order is firmed a star (*) mark will appear in MD04 near the planned order number.
Once if the planned order is firmed, it will not be changed in subsequent MRP Run.
Hope it is clear.
Pl. award if it is clear else pl. update.

Back flush indicator in Production Order
I have a production order with 3 components that are supposed to be set to back flush, but the check box does not default to this. The MRP2 tab of the material master for these components has the indicator set to "always back flush".
Is there a back flush setting somewhere else which does overrides the material master setting?Hey
Looks like you are in the wrong forum,please post your question in Material Master forum
Thanks

Error occured while back flushing
Hi,
I have experienced the typical error while we entered the master data first time and tried to back flush.
the error was saying the cost element can not carry revenue.
it guided us to look into the setting related F I.
finally after completing update part through ca96.
problem resolved.
Kindly explain me how ca96 updated the value or allowed the revenue to carry.
R N GanapuleHi Ganapule,
You have used Revenue items [ cost elements] in CA 96.
As these are primary cost elements,a GL a/c has to be created.The cost element can be created only if the GL a/c exist.This is why you went to FI and created a GL a/c.
Apparently,earlier you must have used a revenue cos element with Catagory: 11 or 12 [Sales / discount recd] .The back flush amounts to an expenditure.With a Revenue cost element cost [ 11 / 12] you can not create a back flush.This is why you had the error message.
After the message you must have changed to cost element cat:1 in the cost element M/Data.As your cost elmt.cat.is 1 [ this is not revenue relevant] the system is accepting the back flush.
Hope this is clear now.If you have any doubt come back;i will guide.
Pl.ignore my earlier reply.
Regards,

Hi,
We are using back flushing for all our materials in production. While confirming the order in the goods movement system shows the quantity as per BOM calculation (order quantity * BOM quantity). System is accepting what ever quantity I enter.
Ex: As per BOM calculation quantity is 100 kg. During goods movement, If I enter 1 kg or 200Kg also system is accepting the quantity. Is there is any setting to set any tolerance limit?
Regards / USDear Umashankar,
1.There is not standard setting to control the quantity to be posted during CO11N.
2.Is there so much of deviation in component consumption than the planned one?If so means modify your BOM first and then
execute the SFC process.
3.Is this your business requirement or just to explore more about the system behaviour have you posted this query?If it's a
business requirement means I would suggest you Check by some enhancement either to stop modifying the component quantity
or else to fix some % of tolerance.

Mass deletion of Back flushing indicator
Dear Experts,
I am having requirement as i want to remove all the back flushing indicator which is assigned to the component allocation screen of routing type N, how to do it for all routing at once, please tell me in detail.
Thanks & regards,
Karad D DHello all,
I am very soory, by MM17 it is not possible but there is another one option, if CEWB is not helping use the following proceess.
prepare a query, select the , select group and counter in the selection screen and ask the technical person to put code that to remove the backfulsh value from the field for given selection values.
It will work.

Back Flush Compared to Manual GI
Hello,
I am comparing the pros & cons of Backflush with Manual GI to suggest the suitable solution .. the points that I could think at top of my head are as follows ..
Back Flush
Pros
Minimal human intervention
User's with limited understanding can function
Faster goods issue process
Cons
Large cumulative variance in system & actual stock figures over time in most cases
Not Recommended for high value material
Salient Feature: Suggested for low cost & less critical BOM components where there is not much financial/ logistic impact with variance within tolerances.
Manual GI
Pros
Accurate consumption can be captured
Better actual & system inventory figure sync
Accurate inventory figures enables better requirement planning
Cons
Recommended for matured users
Labour intensive (Manual activity)
Demand discipline in terms of reporting the consumption error posting due to stock deficit etc
Salient Feature: Recommended for high price & critical BOM components where consumption needs to be captured more accurately.
Please suggest your views on expriences across differrent clients ...Dear,
Apart from Bcakflush and manulgood issue please check this also, Good issue can be done through MB1A, COO1N, CO15. CO27.
Transactions CO27/COIK are lists, based on the order information system, whereas Transaction MB26 is reservation-based. However, it is also possible to make an order-based selection in Transaction MB26 using the 'Production order' selection window. In this case, both lists should also issue the same components for identical orders.
In the event of incorrect goods movements in Transaction COGI, picking using Transaction MB26 generates postprocessing records, whereas Transactions CO27 and COIK send an error handling. If the goods movements cannot be corrected, the records are returned unchanged.
Picking using Transaction MB26 can be scheduled as a background job.
This is not possible with Transaction CO27/COIK.
In Transactions COIK/COHV, you can use mass processing to store goods movements of the picking as future change records and you can then update them later using a report (for example CORUPROC). There is no function of this type in Transaction MB26.
Coming to your pron and cos,
In backflush you need to use the program CORUPROC to update COGI or terminted inccoreted good movement through OPK4.
Else it is very eassy process but 311 you need to use for transfer from the Ware House to Production stroage loaction.
Unplanned good issue you need to define in confirmtaion screen but there are chances of miss mach of quantity due to manual entry. So here you need screen control.
In correct good issue you need to cancle the confirmation but in Manual good issue you can do it seperatly.
But in manual good issue it is possible to confirm the order without good issue.
Hope it will help you.

Hi,
we are using back flush in our repetative manufacturing scenario.
In our process we get the scrap in every stage and client is giving average % of scrap, and we will sell this scrap for kg 24 to customers. And client is asking reducing this from original cost. for this we have added a row in cost component structure as scrap credit.
He want to calculate this scrap automatically.
How to solve this issue. Please guide me step by step process.

what does it mean by back flushing please let me know
Hello
Backflushing is nothing but automatic goods issue. System will automatically posts the goods issue when you confirm the operations.You have no need to make manual issue. It will reduce the effort.
Backflushing is automatic accounting (Goods issues - 261 mvt) of material consumed for production, at the time of confirmation. Eg. When a 4 wheeler automobile is rolled out from assy line, 4 wheels & Tyres are deemed to be consumed and issued to production order automatically by way of backflushing by the system.
Assy line picks the material from stores/ Assy line and use.
No Physical issue & Manual posting ( Goods Issue) by Stores.
Backflush is used for material which are a must and having fixed relationship.
This can be configured in MRP2 Screen,Work center, Routing and production order.
Each has some special function.
If you configure this in routing or production order you have no need to activate this in MRP2 or Work center screen.
MRP2 Screen defines whether material components are backflushed are to be made at the work center.
Sometimes Backlogs are created due to different reasons if Backflush is active
This message tells that "there is no sufficient stocks for the bom component/not able to backflush all the material due to plant data locked etc" at the time of backflushing the BOM Material and hence the Post-processing list is created that you have to Re-process for stock updation of each material.
To avoid this you can confirm the following things.
1.Ensure that suffecicient stock is available in the backflushing locations of each materail.
2.To prevent the generation of "post-processing list" you can block the BOM from getting backflushed if sufficient stock is not available in specified location for the BOM COMPONENTS. To do this change the "REM profile" to "002"in MRP4 view for the BOM MATERIAL.(if the profile is not available you can crate it through SPRO).
3. To clear the existing Backlog use transcation MF47 and re-process(be ensure that required stocks is available for each bom component)
