Parallel & alternative sequence-Routing

Dear all,
Can any one please send the document for how to process parallel & alternative sequence.
I tried but during confirmation its not showing the operation which i created in sequence.
Kindly let me know.

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.

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.

MRP run including Alternative BOM & Routing in sequence.

Dear Experts,
My client has maintained alternative BOM & Routing for there In house production materials.He wants to execute MRP run which can include all BOM's & Routing in sequence. Like, first MRP run should check material requirements as per first alternative followed with second & third alternatives.
Regards,
Rajesh.

Dear Rajesh,
ur req is not possible in that way. coz MRP run select only one PV or BOM and routing at a time and if stock is not available then it will genrate the req.
You can try with this rather craeating an alteranative BOM create alternative group of material so when u run the MRP system will check the stock of first matrial and if short fall is there it will go for next.

Parallel Sequence Routing using RCPTRA01

Hi all,
I've a requirement where i need to Upload Parallel Sequence Routing . I'm using RCPTRA01 for created Standard Sequence Routing . Can anyone help me how to Upload Parallel Sequence Routing using RCPTRA01.

Two ways.
1. Use the parallel sequences you have created and apply 1/2 the time required to process a part to each operation.
2. Use a single sequence and create the first operation with 1/2 the time and a second operation immediately following with overlapping and zero offset time.

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.

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

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,

Foreach -parallel in sequence.

Is there a way to run foreach –parallel in sequence? I tried this but it won’t run in sequence.
workflow
test
$servers
= "servers.txt"
foreach -parallel ($server
in $servers)
sequence {
Test-Connection
-ComputerName $server
test
99upgrade

When I run this code, part of $server and part of
Test-Connection
-ComputerName $server
executes randomly. For the output to make sense, I have to remove the –parallel switch and re-run.
What I was hoping to see in the output was the servername and its IP below it,
without compromising on the total time taken to complete the script.
workflow
test
$servers
= "servers.txt"
foreach -parallel ($server
in get-content
$servers)
sequence {
$server
Test-Connection -ComputerName

WIP or scrap calculation for parallel operation sequences not possible

hi,
i want to calculate wip and scrap along with parallel sequence
system prompts following mesage any suggetions plz send in higher priority
Message no. KV161
Diagnosis
If the routing specifies a sequence of operations that are defined as a parallel sequence, this will have the following effects:
The system cannot interpret the confirmed scrap quantities in cumulative and periodic settlement when it calculates the scrap.
The system cannot calculate work in process at target costs for this order because it does not recognize the relevant operations.
Procedure
If you want to calculate scrap or WIP, do not define parallel sequences.
vishnu

Hi Robert
Though I am seeing this msg for the 1st time - I can give you a some insight into this
It seems you are in product cost by period (PCP) scenario ... In this scenario, WIP is calculated at target cost.... The mechanism of calculating WIP is Confirmed Qty at preceeding operation - Confirmed Qty of next operation..
In your case, since you have parallel operations in your routing, system wont be able to calculate WIP... I am not sure how parallel ops are defined... You need to get in touch with your PP guy....
But, one thing for sure , with parallel ops you wont be able to calculate WIP in PCP scenario

How to create parallel operation in Routing

Dear Sir,
We have 4 operation involved in manufacturing a component . The operation 10,20, 30,and 40 . Operation 20 & 30 can go in parallel and rest are in a sequential manner .
After going thru SDN , I followed the following steps :
a) Created operation 10, 20 and 40
b) in CA02 , clicked on Sequence and created a new sequence with parallel operation option selected . Here I mentioned branching operation as 10 and return operation 40 .
c) Created operation 30 , under the parallel sequence option operation page .
My problem is that now in CA02 , I am not able to see all operation 10,20,30,40 together . The planning dept require that all operation should reflect together and there itself he should be able to know that operation 20,30 will be in parallel and rest in sequencial .
Moreover by selecting on "Operation Graphic" icon , again we are not able to see all operation 10,20,30,40 as per the given relationship .
Kindly help us please.
Regards
Sonia Agarwala

Srinivas,
i think you are looking at an option were in you can confirm or do goods Issue for the order. If that was the requirement, then the control is in customizing transaction "OPK4".
Here in this transaction you need to define "operation sequence is not checked" for the plant/order type combination.
Hope this helps....Please let me know if your need is something else,

Prasobh
