Alternative sequence

hello,
any body please give me idea. how to create alternative sequence of operation in recipe. i 10 - 50 sequential operation. if necessary as per customer i want to run 60th operation other wise i want to stop at 50th operation. so that i want to use alternative operation sequence. how to do this.
thanks advance

hI bhakta vatsalam
you can do this by creating an alternate routing in CA01 for the 2nd sequence for 10 to 60 steps and another one for 10- 50 operations
next after this you need make sure you create 2 different production versions 1 and 2 and assign alternate 1 and alternate routing =2 so this is the different for each customer
and in the config for order type dependant parameters, you need to maintain the setting for selection by production version and similarly in MRP-4 also for BOM Explosion by production versions
so when you create a production order, then the system will prompt you to select which production version you want to use and for that customer, you can select the productiion version which contain the alternate routing with operations 10- 60 in it
if helpful pls reward points
thanks

Alternative sequences cannot be released

Operations in alternative sequences cannot be released
Message no. CO224
im getting error msg while realease alternate sequence operation .
for my alternate sequence operation Branch operation 0020 and return operation 0030.
as of now my first operation confirmed .
im trying to release my aternate sequence operation (as a second operation)
Not all operations were released (see log)
Message no. C2038
once i see the log it showing the first above msg
wat will be the problem.???

Prakash,
You must be talking about parallel sequences. Alternative sequences are the part of routing only. While order creation, one of the alternate sequence gets copied.
By the way if not all the parallel seuences are released, you can release them separately also at sequence level or at operation level.
1. Go to sequence overview, select the desired sequence & click on the green flag.
2. Go to operation overview of the desired sequence, select all the operation & click on the green flag in the bottom. Your problem will be solved.
Hope this helps you

Alternative sequence - operations number

Hi all,
I've got an issue on the alternative sequence.
The standard sequence is made by operation 10, 20 and 30.
I try to add a new alternative sequence to substitute the operation 20 with 2 different operations: 20 and 25.
The system give me an error on the routing: CP331 - Operation: date 28.04.2010: operation number incorrect.
I tried the option to change the standard sequence to 10, 20 and 40, but the error is the same. The system checks the return operation (20) and is not possible to add operations into the alternative sequence with operations number greater than return operation.
It seems that is not possible to substitute 1 operation with 2 operations.
Anyone has solved?
Thanks, regards.

Hi ,
Okay, you want to create an alternaive sequence only.
Standard sequence is 10 20 30
Alternate Sequence:
1.Branch operation : 10
Number of the operation from which an alternative sequence is to replace the reference sequence.
2. Return operation: 30
(number of the operation up to which an alternative sequence is to replace the reference sequence)
Operations: 20, 25
This should work.
Please check and confirm.

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..?

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.

Alternative Sequences in Routings

Hi Friends,
I have a question for altenative sequnces in Shop Floor (Confirmation screen:CO11N).
For a material I have a routing and it has two oprtaions (0010-0020). Operation 0010 has an alternative sequence. In standart sequence the work center ise A and in alternative sequence it is B.
I created an production order. Users confirm production with standart sequences. But if the machine ( Workcenter: A) breaks down they will go on producing with workcenter B. I dont want to create a new production order.
But during confirmation via CO11N I get an error : "Sequence 4 is not defined in order 4011105, check entry" (Message no. RU005)
Infact I have a sequnce number 4 which is alternative to the standart operation.
Where am I wrong? or how can I hanndle this kind of stiuations?
Thanks for your answers.

Dear ,
Check the set up in Order Type Dependent parameters -OPL8 wether u have clicked Alternative Sequence in Impementation Tab under Master Data Setting .Routing will copied to Production Order based on the set up in Order Type Dependent Parametrs

Selection Of Alternative Sequence Automatically By Operation Quantity

Dear All,
We are Using Discrete Manufacturing Scenario, In That Scenario Routing Contains Six Operation and One or Two Operations having alternative Sequence , My client required during production Order Creation , If Operation quantity is more than 250
system should select std sequence else system should select alternative sequence, But i am not getting to mantain lot size for std sequence for operation even I maintaining lot size for alternative sequence , system should not considering alternative sequence. Pls Suggest me how to Resolve Issue
Thanks

Vipin,
It is not possible to control the routing sequence selection based on lot size.
As suggested by forum experts, create mulitple group counters for the same material routing group and you can use them based on lot size.
You can also create production versions for different lot sizes.
Check and revert,

Inbound Queue blocked: Parallel and alternative sequences are not supported

Hi,
Just now, I checked the Inbound Queue in SCM system through SMQ2 and found which was blocked by error message "Parallel and alternative sequences are not supported". Could you please tell me what does it mean? How to fix it?
Thanks,
Quanyin Su

Hi Quanyin Su,
Parallel and Alternative sequences are used in routing.
I believe you are trying to CIF PPM/PDS from ECC to APO and you are getting this queue stuck at inbound of APO.
Both the alternative and parallel sequences are supported in APO.
Alternative sequence is used as alternative modes in APO.
I can think of this as a master data issue.
At least one of your work center used in either of the sequences is not available in APO or is not APO relevant.
Could you please check your master data such as all the work centers used and make sure your parallel and alternative sequences are consistent.
Once you made sure that master is available in ECC, you can CIF it to APO by using CURTO_CREATE transaction in ECC.
Please see below link for Routing and its usage in APO:
http://help.sap.com/saphelp_apo/helpdata/en/99/ed3a981d0f11d5b3fc0050dadf0791/content.htm
You also need to activate a BADI in order to sent alternative sequences to APO.
Below thread has all the details regarding this.

Branch operation and return operation for routing in alternative sequence

Hi all experts.
I would like to ask which table and field store the value of branch operation and return operation for routing in the alternative sequence. I can only find them in structure (PLFLD-VORNR1 and PLFLD-VORNR2) but I want the table field of them. Would anyone please suggest a solution? Thank you.

Hi,
look in table AFFL, here the BKNT1 and BKNT2 refer to those vornr1 and vornr2 of the operation. For example in user-exit ZXCO1U01 you will find the values (BKNT1/2) in the sequence table, and when, for example, filling the LOIPRO01-Idoc, you can use the found VORNR for the E1AFFLL-segment.
See coding for example on determining VORNR1/2 (sequence_table/operation_table as in user exit EXIT_SAPLCOBT_001):
SORT operation_table BY vornr.
LOOP AT sequence_table INTO l_sequence.
    MOVE-CORRESPONDING l_sequence TO l_affl.
* Read the operation table to determine the vornr1 and vornr2
*via the value of field BKNT1/2
    IF NOT l_sequence-bknt1 IS INITIAL.
      READ TABLE operation_table INTO l_operation
      WITH KEY aufpl = l_sequence-aufpl
               aplzl = l_sequence-bknt1.
      IF sy-subrc = 0.
        l_affl-vornr1 = l_operation-vornr.
      ENDIF.
    ENDIF.
    IF NOT l_sequence-bknt2 IS INITIAL.
      READ TABLE operation_table INTO l_operation
      WITH KEY aufpl = l_sequence-aufpl
               aplzl = l_sequence-bknt2.
      IF sy-subrc = 0.
        l_affl-vornr2 = l_operation-vornr.
      ENDIF.
    ENDIF.

Confirmation of parallel sequence operation.

Hello friends,
I want to do confirmation of parallel sequence operation. I use 3 or5 work centers at a time for doing one operation. So i have defined parallel sequences for standard sequence. When I do confirmation of quantity and activity time in CO11N for one parallel sequence, other sequence quantity and activity time should be decreased. But system takes actual quantity and time.
How to make settings , so that quantity and activity values should be decreased automatically for next parallel sequence.
Waiting for Reply!

Dear ,
You are not able get the paralle sequence operation in CO11N because production order will copy the Routing based on the Order Type dependent paramter-OPL8-Routing set up.
Here , basically , you might have chkeced Alternative Sequence and Sequence Exchange field (0) , so while creation production order , routing with operation which are in alternative sequnce will be copied and will be used in CO11N confirmation.
2.You need to maintain "Operation Sequence is not checked " for operation sequence for the Ordertype/Plant combination in confirmation parameters using transaction OPK4.-Confirmation parameters of Order
Try and revert back

Routing Sequence Selection

Dear all,
I have a routing with an alternative sequence created.
I would like to be able to select the sequence of the operation while confirming (CO11n) and not while creating the production order.
Kindly let me know what's the possibility of that.
in Co11n, when I write operation 0010 and sequence 1 instead of 0 it says "Sequence 1 not defined in order xxxxx, check entry"

Maybe you can tell me what's the best practise for this case
I have 2 work centers
FUR11
FUR33
each has different capacity, during the production order, we can work on FUR11 for sometime then shift to FUR33, and it's not a must that this happens. However, I want to be able to confirm the ACTUAL time occuring on any of them. I thought about alternative but in this case I have to know from the begining which alternative I'll be using during the creation of the production order and this is not valid in our case.
What do you suggest?
I was thinking of making them parallel sequences.

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
Edited by: madhu333mac on Feb 13, 2012 9:14 PM

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.

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.

Sequence selection in Rate Routing

hi,
In Normal Routing in sequence overview - extras - new entries we can find the option of creating a Parallel or Alt sequence, but in Rate routing there is no way to select the type of Sequence. It by default shows Parallel sequence.
Pl. let me know the step by step proceduer to create a Alternate sequence in Rate routing.
regards

Dear Rishi,
We cant create any alternative sequence for a rate routing.This is one of the difference between routing and rate routing.
Rate routing supports only standard and parallel sequence.
If alternative sequence is present in a routing,then at the time of order creation the system gives a pop to select for alternative
sequence or to skip it and proceed.
For this under OPL8,for plant order type combination the field sequence exchange should be having value 2 - manual selection.
Creating production version or sequence in my understanding depends on the business requirement.
Check and revert
