Alternate Sequences in Routing?
Dear Guru's,
In our production process some of the operation we will perform externally by sending it to vendor. For this we are maintaining the alternate sequences in routing. So, when ever we want send the material to vendor to perform the external operation will exchange the sequence in routing.
So, in some cases we have to do it in mass. I hope is there any t-code or any other way to do it.
Need valuable inputs please.
Thanks & Regards,
Madhu.G

Dear Madhu,
Is it only a manual decision whether to process the operations in-house or else to be sent to the external party or is it based on
the lot size say if the order quantity is for more than 100 it's to be given to the external party means then define a lot size for
the alternative sequence for a lot size rangining from 101 to 9999999(For example).
In this case during order creation the system copies the alternative sequences automatically.
Check whether this works out for your requirement or not.

Scheduling of Parallel Sequence in Routing & Production Order
Hello Friends,
I have gone through sap library & many other threads related to maintaining & scheduling of parallel sequence in Routing as well as Production Order.
For the example, I have 3 operations : 0010,0020 & 0030.
I want to maintain 0020 & 0030 as Parallel Operations ( Parallel Sequence) i.e. for both operations I have maintained same lead times so that both should start & end at same time parallely.
First of all, I have maintained all operations in standard sequence 0 all 0010,0020 & 0030 operations and also maintained tick in Required splitting check box.
Same way , I have maintained operations 0020 & 0030 in Parallel sequence with branching operation as 0020 & Return operation as 0030. Ref. sequence i have maintained as 0 (Std. Sequence).
Now when I am checking in Graphic it is not showing both operation 0020 & 0030 as parallely scheduled and hence same is not reflected in Production ORder as well.
Kindly share your valuable views reg. what may be other settings for parallel sequence which I may be missing.
Thanks in advance.
Regards,
TejasHi Abhijt,
Thanks for your reply. I went through your thread & I followed same steps as mentioned by you in your suggested threads.
I have removed Parallel sequence fully & maintained Required Overlapping for all my 3 operations : 0010,0020 & 0030
I have maintained workcenters as below :
0010 A Set up 2.0 Hrs Machine 5.0 Hrs Labour 1.0 Hr
0020 B Set up 2.0 Hrs Machine 5.0 Hrs Labour 1.0 Hr
0030 A Set up 2.0 Hrs Machine 5.0 Hrs Labour 1.0 Hr
I checked scheduling in routing itself same way you suggested with start date today's date & forward scheduling it gives following results :
0010 start time 07:00:00
0020 start time 07:13:42
0030 start time 09:14:39
My concern is with mainly start time of operations 0010 & 0020 since for both of these are processed on different workcenters A & B respectively then why not starting exactly on same time on 07:00:00 AM only instead another operation is starting on 07:13:42AM. I am unable to find how this difference of 13mins 42 seconds is coming.
Kindly provide your feedback. Also let me know if you need any more details.

Hi all,
I have defined a parallel sequence in routing linked to standard sequence. i.e. 0
Stand. seq. has one operation 0010 (work center L1)
Parallel sequence has 3 operations 10, 20 and 30. I am trying to make 10 (work center L4) and 20( WC L5) as parallel operations.
I have 2 quesries regarding this.
1. I am putting branch operation as 10 and return operation as 20 but I am getting error,
'The return operation is not defined'
2. I want this sequence to get selected in production order automatically in as operations but system ia selecting main seq i.e. with operation with WC = L1.
Let me know if I am missing something, concept wise or setting wise.
Regards,
YogeshHi,
Your first question:
You cannot have return operation as 20, as you standard sequence has only operation 10. So your branch operation and return operation has to be 10.
Your Second Question:
In the production order go to Sequence overview (Shift+F8) to select the sequence and then go to Operation Overview (F5) to look into the details of the operation.

Hi,
what is the purpose of sequences in routing ?
normally all the operations list we can put and create routing ?
if we use sequences will the operations of all the sequences taken in to account while doing standard cost ?
are these sequences are of reporting purpose or any thing else
can any one clarify ?
regards,
Madhu KiranHi,
we use REM , no order reference
our routing have sequence 0 to sequence 11 etc.. based on operations , these are not parallel sequences
sequenec 0 is mainline operations
sequenec 1 is some sub assembly operations etc...
my doubt is when cost is run whether it will take these other sequences other than 0 also in to consideration ?
with out giving the sequences if all operations are put in to routing what will be the issue ?
one doubt with this is
sequence 2 is handling time 2 min and when we assign return operation to this sequence as operation 30 of main line where in that operation we give time as 1 min suppose
whether system takes 2+1 = 3 mins time ? or 1min only from mail line sequence ?
pl clarify

Production order for alternate BOM and Routing
Hi All,
In my business(Discrete) scenario I have alternate bom and routing has group counters. some times i should use first BOM and First group counter. Then next Bom and next group counter. But lotsize is same( prodcution version how to assign).
When creating production order i should select which ever i need.

Hi,
For your requirement you can define your Order Type Dependent parameters OPL8 as:
Production Version : 1 Manual Selection of production Version.
In this case every time when you creat your Production order System will ask for the Production version to be selected. You need to select the PV manually then only you can proceed further.
This setting is applicable only when the Production Order is Created.
It will not effect the Planned Oredr creation via. MRP Run..
Hope this helps..

Table and field for actual sequence of routing
Dear guru ,
i have a production order and i use alternative sequence in routing.
I dont know which field and table of production order that give me the actual sequence
Of the routing That I am using for this production order.
Thanks in advance.Dear,
there are two diferent tables AFVC and AFFL
In AFVC we have sequence no field and AFFL also have sequece field it is called - PLNFL
Hence it is the differenciating factor between 2 sequences
AFFL output

Settings for Parellel sequence in routing
Pl. tell me hoe to do settings for Parellel sequence in routing , if there are 4 opn s , 10, 20 ,30, 40 .
10,20,40 are in standard seq. , but 30 is in parellel with 20.
pl. revert.
Regards,
RMHi,
In your standard sequence, create operations 10, 20 & 40 as per normal.
Now click on Sequence icon (Ctrl + F5), then click on new & in the pop up box select parallel operation.
In the popup box give a meaningul description, give the branch & return operation as 0020. Now a parallel sequence is created, double click on this one & add the operation 30 in this.
You can go to the graphical view & check if it as per your need.
Hope the above solves the issue.

Std infoobject for "Sequence" in routing
Hi,
Is there any infoobject existing delivered by SAP for the field "Sequence" in Routing (Tasklist) of Production Planning?
RajHi
Yes you can use the parallel sequence as you mentioned.
before you need to know the operation time funtion . As per your routing if the timing used in the operation is
Threading > marking > painting . you can use the more machine in 1st operation than the 2nd than the 3rd
if the opration time is more , then use more machine , inorder to reduce the leadtime of the full operations.
or
if your timing used in the operains are like
Threading < marking < painting , is this user case , then make it possible to minimise the use or machine for theading operation.
2. another way is
you can split in the routing with no of split. if your workcenter has more than 1 capacity
so the operation can split into the no of machine(split ) as you required. -
Confirmation in alternate sequence
Hi
System proposes wrong qty to confirm after alternate sequence confirmation.
op 10 - 10 ea
op20 - 5 ea op11 - 5 ea(parallel)
op30 - 10ea
In confirmation, after i confirm op10 for 10 ea, i confirm
Case A: op20 - 4 ea (Final confirmation), op11 - 3ea (Partial)
system proposal for op30 is 8ea
Case B: op20 - 4 ea (Partial), op11 - 3ea(Partial)
System proposal for op30 is 6ea
why it is not proposing 7 ea for op30.Dear,
In OPK4 check the following
Operation sequence = Operation sequence not checked....then do confirmation it will work as required by you. -
Alternative Sequence in Routing
Dear All,
I have a routing with 2 operations, and an alternative sequence branching in/out for operation 0020.
Now I have created a Production order, finished operation number 0010, finished half of operation 0020 and confirmed half the quantity, now the machine stops and I want to use the alternative machine.
How can I do that?
It wouldn't allow me to use the alternative in confirmation, only allows me to choose it while creating the production order. How can I fix this issue?
In my origional routing I have 1 standard sequence, and once the machine brakes, I go to CO02 and create a new alternative?
However, in my original routing I dont want to state that I'll be manufacturing this production on 50% on machine 1 and 50% on machine 2.
The problem only occurs if the workcenter I'm working in develops a downtime. Where can I list the other work center I will use respecting the capacity, etc..?
Edited by: Rafik Wassef on May 21, 2009 12:01 PMRafik,
There are three types of sequences you can maintain in the routing, i.e. standard, alternative & parallel.
As soon as the order is created in which this routing is the master data, any one sequence either standard or alternative sequence gets copied to the order.
Parallel sequences will be copied to the order.
That means the sequences which are alternative to each other never be a part of the order i.e. you can maintain those in the routing but while order creation only one out of them gets part of the order. Also you can not maintain alternative sequence in the order.
Only parallel sequence can be maintained in the order.
That's the reason I suggested you to maintain the same to tackle this issue..
If the main work center is under maintenance then you can replace the work center with the desired work center in the order itself. Why secific need to maintain the another sequence?
Hope this helps you.

Hi Friends,
Please help me to map following scenario of routing.
Suppose I have 5 CNC machines( Threading operation), 4 marking machines ( marking operation) and 3 painting machines (painting operation). Here, I can do work on CNC for maximum 5 components at a time as there are 5 machines. After that i send the job for next operation marking and then Painting.
Here if i have to create 5 parallel sequence and assign each CNC machine to operation threading in sequence?
Waiting for reply!
Thanks 1Hi
Yes you can use the parallel sequence as you mentioned.
before you need to know the operation time funtion . As per your routing if the timing used in the operation is

Alternate sequence with no "return" operation
Hello PP experts,
I have a routing with already a ALT sequence and no "branch" operation for the same, only my return oper is configured (this is a kind of converging routing).
I tried to enter an ALT sequence without a "return" operation but in this case it is not authorized.
Seams "branch" operation can be optional, but "return" is mandatory.
Can you please confirm/advise how I could simply model a "diverging" routing sequence (going out of my main routing branch and no return on it).
ThanksThanks for your answer but this does not solve my pb.
To me there are 2 business case which can lead to model a // or ALT sequence in addition to a main seq.
1) As per your explanation, it is a need to increase and optimize the throughput based on lot size.
OR
2) In my case it is regardless of lot size and throughput, but it is to model a manufacturing process that needs to have a main sequence for production, then based upon some process triggers, to "branch out" the main sequence and terminate this process in a different way based on those triggers results.
I already model one of my biz case where I need a main sequence on my routing, and this main seq is then joined by an ALT seq on a particular operation (my return operation). In that case usage of alternative seq with "branch oper = empty" and "return operation = 0040" is working well and fits my needs.
Seams to do the reverse, that is to leave my "return operation = empty" is not allowed.
Thanks,

Alternate Sequence operation confirmation ...
hi folks ,
i have 3 operation in STD seq like 10, 20, 30
and for the std sequence thr is alternate seq. which contain alternate operation for
20 th operation of STD.
FOR operation 20 now :
In STD seq only one activity Machine time required for 1 item to process is 10 min.
In ALT seq only one activity Machine time required for 1 item to process is 5 min.
when i am confirming the 20 operation in CO11 the time required for the opr 20in ALT seq opr. 20 is not appering on the QTY / YIELD .
regardsHi,
You can cross-check in the production order, operation overview whether the operation 20 is that of the alternative sequence. If not when you create the production order the sytem will inform that alt. seq exist. Here you have to choose the alt.seq.
Also check the settings in the confirmation parameters (opk4).
Propose qty/standard value is to be selected.

Standard cost with material with alternate BOM and Routing
I have a set up where the same material can be manufactured in 2 different production lines and each production line has two different BOMs and Routings. If I want to have a blended standard cost for the material what are our options?
We do not want to do split valuation.
thanks a lotHi
You can different PCC (Product cost collector) for both lines of the same product (Product cost by period).
You can define a production process within a product cost collector for each line of production with a combination of BOM and Routing. TCode KKF6n. It would generate a order number for each production process.
You can use each order within the PCC for each production line to capture the costs for seperate lines.
