Sequence in routing

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 1

Hi
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.

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,
Tejas

Hi 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.

Tejas

Parallel sequence in routing

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,
Yogesh

Hi,
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.

Sequences in routing -reg

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 Kiran

Hi,
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

madhu kiran

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

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,
RM

Hi,
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.

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 PM

Rafik,
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.

Select query in routing(operation,sequence)

Hello frds,
i am into change routing BDC actually i want a select query .....for like existing of operation for a particular sequence in routing....
if i will found operation for particular sequence i will run the bdc code lese i will exit...any one can help me...
just provide me a query....to check existnece of operation for a particular sequence......ASAP...

Why on earth would you want to keep the queries separate? As Tom Kyte would say, databases are born to join!
Providing emp_id has an index on it (and it should, assuming it's the table's primary key!) your "complex" (or, what I would call simple*), it'll most likely be faster than doing it separately. You've not got the context switches for one thing.
If you want to see what the optimizer does with your query, you should run a trace on the query. An explain plan would give you an idea of what it's going to do, too.
In general, doing something like this procedurally is going to almost certainly be worse than doing it in SQL (and by worse, I mean slower).
* I'd hate to see what you'd call some of the monster queries I work with, if you think that query is complex!

Routing-Sequences Error in co11n

Dear all,
Can any one please share the screen shots how to process the sequences in routing
I have tried by using help portal but i dint get any differences on that.
While confirming in co11n,that particular sequences also not get displayed in sequence column.
Regards
Rajasekaran

Dear Raja Sekaran,
Check this link to understand more about alternative and parallel sequences.
Why Rate Routing is (recommended) used in Repetitive Manufacturing?
Alternative sequence of operation can be created only through routing and when it comes to production
order you can copy either the standard sequence or the alternative sequence of operation.
During production order confirmation in CO11N,in the F4 option you can see the entire list of operation
along with the sequence.
First ensure you have parallel sequence of operation exists in the routing level and then the same gets
copied to the production order and at the time of confirmation you can see the list display.
Check and come back.

I want to use a Netgear router instead of Airport Express...

I'm trying to create a network of my Mac and my wife's Windows (Vista) laptop, really just so we can print wirelessly from the laptop.
Currently my cable broadband modem is linked to Airport Express which "feeds" the Mac. I'd like to remove the Airport (whose range I imagine will be insufficient) and replace it with a Netgear DG834G wireless router, then add the laptop to the network.
I've looked around this site but haven't found any advice that addresses this particular issue and am hesitant to start changing things for fear of losing my online connection and also my access to the good people on this forum.
Can someone point me to any pages that address my query?

Basically all you need do is power everything down; modem, router, computers. Then power up in 2 minute sequences; modem, router, computers in turn. However, you should read the manual of your new Netgear router so you set it up properly. Having gone through this I can say it is quit easy. Don't use the CD supplied. Connect your Mac to one of the router's LAN ports; power the router and the Mac. Launch a web browser. You should get the router's admin page. default user name is 'admin'. Default password is 'password'. You should at least change the password so no one outside can gain access to your router. Then you should change the name of the SSID to whatever you want to call your network. Then you should set up your wireless access password protected. Then power every thing down and set up the network as above. There are tweaks you can add. If you have issues post back.

Material Assignment in routing ?

HI Gurus,
can anybody please Explain in which business scenario Material assignment In routing is used.i am confused about the functionality in the business .
Thanks&regards,
Venkat.

Dear Venkat,
Routing is the sequence of operation/activities through which production takes place across the work centers ( machines ) which is created by pp consultant.
Example : If you want to stitch a shirt we many need to do following activities.
Taking the measurements from the user
Cutting the fabric according to measurements
Stitching / sewing ( Joining the parts like collar / hands / Yoke / Pocket / Cuffs....Etc)
Buttoning ( adding the buttons to shirt)
Quality checking
Ironing
Packing ..etc.
In the same way based on the product you are going to do it might have some steps to make it, we will maintain the same steps / sequences as ROUTING in SAP PP.

N.S.Rao

Parallel sequence - scheduling operation

Hi,
when I was creating parallel sequence in routing I was faced with problem in scheduling operation.
After making a routing with parallel sequence, which are executing on the others work centers, system doesn't take into consideration the fact that order is divided on for example two work centers ( parallel sequence ! ).
How to divide the time of operations for equal parts ( or different proportion ) in two work centers.
Please help me solvede this problem.
Artur

Artur,
The logic of parallel sequence is bit different from what you expect.
The parallel sequence is the sequence of operations which runs parellel to main sequnce.
But you can use it to serve your purpose.
After creating the parallel sequence in the routing, select the standard sequence, click on operation.
In operations overview, select the desired operations & follow path, 'Details'-- 'operations' or press F6.
In the operation details screen, under 'Unit of measure conversion', maintain value against 'Header' as 1 & against 'Operation' as 0.5 (if you want to divide the value equally).
Navigate with the arrows in the upper left & maintain these settings for the desired operation.
Now click on 'Sequnces'.
Select the parallel sequnce & repeat the above given procedure for the desired operations in the parallel sequences aslo.
Now whenever the order will be created, the order quantity will be divided equally on the sequences & accordingly scheduling will yake place.
Hope this helps you.
