Operation scrap in routing
Hi All,
I want to know,what is the effect of maintaining operation scrap in routing?It does not effect the component qty allocated to that operation(as it dus in case of maintaining operation scrap in BOM).
Pls guide
Hi Gautam,
Operation Scrap In the Routing is the amount of scrap (in percent) for the operation.
The effect of operation Scrap in the Routing :
The scrap in the operation causes a decrease in quantity in the next operation because the quantity to be processed is reduced by the scrap quantity.
The reduction of quantity is taken into account in scheduling and costing.
Hope you understood the point.
Thanks,
Srinivas

Can we maintain the operation scrap in each operation where ?
hi pp gurus
I have one finsh product Core
first operation is core making
second one is core assembly
so in each operation there is scrap say for first 5%
and for 2nd operation say 2%
I hav given the operation scrap in Routing but when I taking MRP Run it is not
calculated the excee Material Required
so Pls Solve the problem
hoping for reply
devHi
This can be handled in 2 ways.
The options used by me in similar situation were
1 Yeild the BOM to that effect.
2.Define the scrap in Material Master.
Hope this helps.

Operation Scrap senario not working
Dear All,
I have maintained the 5% operation scrap in routing. I have created the production order for 100 Qty and confirmed order, but system is not proposing the 5 % scrap anywhere.
What is the issue?
Kindly advise.
Regards,
AnilDear All,
Thanks V Much for your prompt replies.
I've checked the Goods movement in CO11n but system is proposing 100 qty not 105 qty.
System does not increasing the required qty.

Hi Experts
In the operation details of routing- CA01 there is control -either based on time or Quantity for every operation. What it mean. If time based is it denoting the time for the particular operation. What it mean if "quantity based " is preferred.Can I have details please.
Also will you give a scenario with some operations mentioned where I can use routing.
PranavHi Gajesh, Thanks
I take your case - "Suppose you have 4 operation. Forming, lathing , quality checks and painting. Normaly in production system you will have a quality check in between the process".
here check necessary in 3rd step - quality check. So am I to select time based / quantity based for operation -3 only ( because only it will have MIC ). Can I go without selecting time based / quantity based option also (if so how - what option i need select in the operation details for the 3rd operation).
Next, in CO11N. I confirm operation -1 ( here what option I hav to select - either partial confirmation / final confirmation). As per my logic, only partial confirmation need to be selected (what quantity I hav to enter here for yield- is it the total production order quantity = total target quantity).
similarly, 2nd operation- lathing- I select partial confirmation- enter yield/scrap etc
3rd operation is qc check- is it possible that production person will confirm this step in co11n itself without waiting for the qc person to confirm using QA32. ( here what yield to be entered and how if we use QA32 )
4th -painting - finally ( as my logic goes -final confirmation selected and operation confirmed for the total production order quantity)
Tell me if right. I noticed that if final confirmation option selected in the first operation itself, all the 4 operations can be confirmed in the co11n itself ( by selecting final confirmation option for all 4 operations)by the production department. Am i wrong somewhere. If this is so, how Qc person has control over the process.
Also what yield /scrap quantity will be entered for each 4 operations in co11n ( is it mean the wastage occuring in each step =scrap and remaining quantity =yield). If so the final yield by operation -4 will be surely less than the production order quantity ( if wastage occurs during lathing/forming)

Standard test key in operation overview in routing
Iam not able to see standard text key in operation overview in routing beside control key column. Any setting for it .
hi,
I dont think that that the STK is dispalayed in the operation overview.
so first ensure that the STK is defined in the WORK centre basic data view. Then goback to the operation view of u r routing.
Double click on the operation ,then u will find in the OPERATION details view that u r STK is diplayed just below your CONTROL key.
GURUS pls correct me if i am wrong,

Mass change for QM at operation level in routing
Dear Experts,
I have to carry out mass change for Quality Management at operation level in routing. The steps that I am carrying out for an individual record are as follows.
1. CA02
2. Inspection point 100 is maintained at header level
3. Go to operation level
4. At operation level work center and control key have been maintained
5. Double click on operation
6. When I scroll down here I go to Quality Management: Inspection Points view.
7. There by default in Insp.pointCompletion system shows the option as u201CQuantity, valuation (production) and radio button selected default indicates u201CQty-relatedu201D
8. I want to change these options as only u201CValuationu201D and u201CNo relationu201D respectively
My queries are,
1. Is there any T-code available to carry out these changes in mass?
2. Is it possible to do this without any Z development?
I am doubtful about using LSMW here. I would be highly grateful to you if someone can help me step by step.
Thanking you,
Anand RaoHi Sujit,
Thanks for your reply!
I tried CWBQM. Unfortunately could not succeed. I think may not be feasible through CWBQM.
But I came across T-Code CEWB . There I opted "SAP_OPERATION" as working area and it worked. Its quite useful T-Code.
Thanks again for your input.

How to call a previous operation in the routing in the backend?
(We have a requirement to call a previous operation in the routing in the backend and create-assemble-complete the SFC.)
Routing would be u2013 OPERATION_1 -> OPERATION_2 -> OPERATION_3
The SFC has not been create and we are using u201CCreate SFC On Demandu201D.
The production operator is given the SFC value to use, however, the POD is configured to START the SFC at OPERATION_2
The desire is to process the SFC at OPERATION_1 as a u201Cblindu201D operation to production.
The question: If we use a PRE_START activity, is it possible to launch the PRE_START activity at OPERATION_2 and have the activity:
1) Create the SFC,
2) Start the SFC at OPERATION_1,
3) Assemble a child SFC (part of the activity information),
4) Complete the SFC at OPERATION_1,
5) Upon completion of the SFC at OPERATION_1 finalize the activity and allow the SFC to start at OPERATION_2 normally?
Thanks and Regards,

a managed property only gives you a anlde to a bean or property, it doesn't execute it. To execute a bean, you can use a custom JSF PhaseListener that calls a bean method. The reference to the bean is achieve through value binding
ValueBinding vb = FacesContect.getCurrentInstance().getApplication().createValueBinding("Name of Managed Bean);
TypeOfBean theBean =(TypeOfBean) vb.getValue(FacesContext.getCurrentInstance());
.... theBean.theMethod() ...

Assembly, component + operation scrap
Dear All,
[I raised this issue on MM board and I was advised to come here. Maybe you can help me.]
I haven't got experience in SAP, that's why I'd like to ask for your help in this issue.
Could you highlight/explain how these work?
(effects on MRP run + behaviour when booking against PrdOrd; e.g. when I book against PrdOrd what will be the movement types?)
thx
CsabaHi,
Assembly scrap:
Assembly scrap takes into account all the faults that occur when the
components are put into assembly.
The system automatically increases the qty to be produced by the
percentage of scrap.
can be maintained in MRP 1 View as a percentage
Reqd qty 100 pcs
Assembly scrap 10 %
After taking scrap reqd qty is 110 pcs
Component scrap:
Component scrap takes into account all the faults that occur before the
components are built into assembly.
Can be maintened in MRP 4 view if the scrap is going to be for all boms
can also be maintened in BOM item detail screen if the scrap is for
particular Bom .
Reqd qty 100 pcs
Assembly scrap 10%
component scrap 10 %
Reqd qty 121 pcs of components
Operation scrap :
Befor high value components are built into assembly the system carries
quality control check for the assembly.Faulty materials that were taken into account in assembly scrap aren ot passed on to the next operation and hence they are removed.
Maintain the operation scrap in the BOM item details screen under general data /qty data.
Qty to be produced 1000 pcs
Assembly scrap 10 %
component scrap no entry
net indicator not set
scrap qty 100 pcs
qty to be produced 1000 pcs
Assembly scrap 10 %
operation scrap 1 %
net indicator set
scrap qty 10pcs.

Tables to see operations of a routing that are already confirmed?
Hi everyone,
I would be very grateful if someone could tell which tables should I access in order to know if an operation in a routing has or hasn't been already confirmed.
Thanks in advance and best regards.
Ben.If you are doing confirmation by operation wise by CO11N,change the confirmation type from partial to Final conf in the screen.
If you are doing by CO15, indicate radio button final confirmation when doing conf.
If you want automatic selection of final confirmation goto SPRO>SFC>DEFINE CONFIRMATION PARAMETER.
U can check in table AFRU table Order Confirmations.
Completion confirmation number for the operation.

Costing of the operation in the routing
Hai gurus,
I have 5 sets of operation in the routing.
a) Operation 10/20/30/40 and 50
b) In Operation 10/20 and 30 the , costing is active in control key PP01
c) In operation 40/50 the costing is in active in the control key zp01
If that is so, whether operation 40 and 50 will be considered for costing during confirmation or not
regards,
sekar chandHi,
If the costing relevancy is ticked in control key & in operation. Along with the relevant prices maintained in KP26, system will do the costing. To double confirm, run CK11n for that material & verify the same.
Revert if you face any issues.

Rework operation in the routing
Hi All,
We are in the REM process, We plan to change the existing Routing so that need to include the rework as the operation in the routing.
we are not going to do rework for finished product (i.e after the confirmation). if any problem , we make it as the scrab.
we need to do the rework for the product before final stage of inspection itself . ie. we have a inprocess inspection .
i.e we have a operation called soldering, if this is not done properly, we remove the soldering and do it again as a rework.
1.how to mapp this operation as rework in the routing
2. whether we need to create the separate routing for rework or we can add this rework operation in the same existing routing itself ?
3. if we do rework for the assembly, we can do create the rework, but in the component stage itself
we need to do the rework.
Edited by: raj on Jun 5, 2009 7:37 AMHi Ramaling,
my scenario is like , we have 10 operation, after the 3rd operation, we have the inspection as the 4th one.
if any qty have rework , we have done the rework manually .
so client need us to create the WC for rework and they need to find the cost inoccur for the rework
after rework was done ,all the other operation will continue for the reworked materials.
how to include this rework WC in the routing what we used.
is it advisable or not
if it is not how to mapp my scenario ?

Master Recipe - Operation Scrap
Hello,
We use master recipes. We are trying to maintain scrap% value for an operation/phase, and I don't this field on the screens.
Any thoughts? Is there a way to maintain scrap at operation level if we use Recipe?
I tried OP5D and I see that Scrap field is already listed as an Input field.Hello
There is no operation scrap for master recipe and the phase scrap cannot be directly entered into the recipe like it is in the routings.
You can use material quantity calculation to calculate any loss during the phases.
Best regards

Operation scrap and expected yield variance
Hello guys,
I have a question on the operation scrap and the expected yield variance.
I have a product which has four operations, and on one of the operations (2nd operation) the operation scrap of 10 % is maintained.
So, I have created a production order for 100 Pcu2019s.
For the confirmation, I confirm first operation with the total order qty (100Pcs). After the confirmation the expected yield of variance of 10 Pcu2019s is set on the order.
I just wanted to understand why the expected yield variance is set with planned operation scrap. According to my understanding, the expected yield variance is only set if a scrap value is mentioned in the confirmation.
I am having a problem because my 4th operation is a milestone operation ( I confirm 2Nd, 3rd and 4th operation at a time.
I donu2019t use the back flushing option coz I do my GR in MIGO.
So here is the situation.
I created and order for 100 Pcu2019s and I confirm the first operation for 100 Pcu2019s
Second milestone confirmation (2nd, 3rd, 4th ops) for 40 Pcu2019s u2013 GR is done after that.
Third milestone confirmation (2nd, 3rd, 4th ops) for 40 Pcu2019s u2013 GR is done after that.
Fourth milestone confirmation (2nd, 3rd, 4th ops) for 15 Pcu2019s but I can only receive 10 Pcu2019s because of the operation scrap and expected yield variance.
Thanks,
sashi vardhanDear Shashi,
Since you have maintained 10% as operation scrap system considers that 10% of your total qty in the opration is scrap material and hence system allows only confirmation of 90 components only.
This is std SAP behaviour.

Hi
How does operation scrap work
Can you please explain how it works during planning and execution with an example plsHi,
Operation scrap is a planned scrap. It means that for every order during this opn, scrap qty will generate, that might be in %.
Opn scrap is assigned in BOM componenet details. So when system explode that BOM operation scrap will come to effect.
Ex:
Order qty 100.
Opn scrap 10%.
When you do goods issue by MB1A against that order system will issue 110 instead of 100 no's due to opn scrap of 10%.

Difference between parallel sequence and parallel operation in a routing.
Hi Experts,
Can any one explain me with example the difference between parallel sequence and parallel operation in a routing? wHEN CAN WE USE PARALLEL OPEARTION AND PARALLEL SEQUNCE WITH COMPONENT ALLOCATION.
Regards
Deepak sharmaI think u need to modify ur quest... i think u r asking about Parallel sequence and alternate seq. Below are the details from SAP site.
A parallel sequence enables you to process several operations at the same time.
You use an alternative sequence for example, if
--The production flow is different for certain lot-size ranges
For instance you can machine a work piece on conventional machine or on NC machines. A NC machine has a longer set-up time than a conventional machine. However the machining costs are considerably less. Therefore whether you use NC machines will depend on the lot size.
---The production flow changes under certain business conditions.
For instance, if you have a capacity problem, you have some production steps performed externally by a vendor.
