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.

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

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.
Cheers,

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

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
bhakta

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

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.

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.

Alternative bom and routing selection in planned order

hi
how i can config the system so that while creating planned order
system has to select the alteranative SEQUENCE and alternative routing ?
at opl8 we do this for production orders what about the planned oreders
in scheduling parameters of planned orders we can give only selection ID
WHAT about alternative SEQUENCE .
IN the same way how the system selects the alternative BOM with date in planned order
iam not creating production versions
plz suggest
sasikanth

Hi,
If you r using Prod Version then system pick ups the BOM attached in first valid production version.
So, normally put more frequently used BOM in your first Prod Version.
You have more options to use:
- lot size (defined in BOM header)
- production version (several option you have: lot size, manually assign a PV to a planned order)
- you can use explosion date (OPPP, Logistcs > Production > MRP > Master Data > BOM by date)
MRP 4 (in material master) > 'BOM explosion/dependent requirement' tab > you can set selection method according to your wish.

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.

Vinod
