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.

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.

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 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.

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

Wrong Operation number(Activity Number) showing in Production Order

Friends
I have created a production order.
Wrong Operation number(Activity Number - RESBD-VORNR) is showing for some of the Production Order components(all are phantom components only) where as the activity number in its Routing components (RCM01-VORNR) is different. So we need to change the activity to correct activity manually in change production order screen(CO02)
I found one SAP Note 104322 - Error in reallocating phantom (When reallocating phantom components in a production order to another operation, different errors can occur:
-- not all dependent components are allocated to the correct operation). We are on ECC 5.0 . This note already exists in our system
This issue happened only with one BOM . Many other BOMs ( similar type) donot have this issue.
Can some one from the group help me to resolve this issue?
Thanks in advance
Please let me know if you guys need more details
Thanks
MVSSAI

Hi MVSSAI,
I am just a bit confused if you are talking about wrong operation nos. or wrong activity nos. If I am correct, it should be wrong operation nos. which fetches the activities that are defined in that work center.
If wrong operation nos. is getting selected then
Please check if the system is configured with alternative sequence under T.Code: CA01 for a particular group & group counter (just in case you are using nos. of routings for the single material).
If yes, then check if you have defined priority of the sequence i.e. in which order it has to taken.
If yes, further check if you have aligned automatic routing selection depending upon the B.O.M. alternatives in routing itself.
Just in case you have maintained any of these the routing will get automatically selected depending upon the priority that is given to work center and hence different operation nos.
Regards,
Pankaj

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

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

Connecting the Sequence Operator to the Mapping Output Parameter?

my OWB Client: 10.2.0.2.8
my OWB Repository: 10.2.0.2.0
I need to obtain a sequence number (from the Sequence Operator), then output it
using the Mapping Output Parameter, if possible.
I have tried two things:
1. Connect Sequence Operator nextval variable to the Mapping Output Parameter.
This generates error:
"Table,View Or Sequence reference 'xx_SEQ.NEXTVAL' not allowed in this
context"
2. Join the Sequence Operator nextval variable with a source table, then
connect a port from the dataflow to Mapping Output Parameter.
This generates error:
"Mapping Input Parameter and Mapping Output Parameter are intended to be
executed before and after the data flow of the mapping and cannot accept
inputs from any part of the data flow."
From what I have seen so far, it appears it may not be possible to use the
Sequence Operator along with the Mapping Output Parameter. If Im wrong, please
let me know of an example of how the Sequence Operator and Mapping Output
Parameter can be connected.
Thanks

User -
Look at adding a Post-Mapping Process to your mapping, there you have a choice of built in functions or custom ones that could return a sequence value for you. You may have to create the sequence outside of OWB ...

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

Sequence Operator

How can I use Sequence Operator within a single mapping ???
I get a single value with Sequence.NextVal. Then, I need to use this value for further operations in the same mapping. For example: use value to update target table(s), pass the value to Post-Mapping Operator, pass the same value to Mapping-Output Operator and so on.
Thanks in advance

If all there is on the mapping is a sequence and a table, it looks as if he wants to use a single sequence value to either insert a single row to the table, or update the table with a single sequence nextval.
This is a valid task, but not really the sort of bulk inserts/updates that mappings are designed to do.
Assuming that I am correct, what I would suggest in this case, is replace the sequence with a constant of type number and set it's initial value via it's expression property to the sequence nextval. I would suggest making a database function such as:
CREATE OR REPLACE FUNCTION get_next_sequence_number_fnc (sequence_name in varchar2)
RETURN NUMBER PARALLEL_ENABLE
IS
retval number := null;
BEGIN
-- Sequence nextval wrapper to overcome SQL limitations on nextval
execute immediate 'select '||sequence_name||'.nextval from dual' into retval;
return retval;
END;
to do this task, so the Constant would get instatiated with an expression of get_next_sequence_number_fnc('your_sequence_name')
I haven't worked a major project yet that didn't need to use a get_next_sequence_number_fnc function to be able to access a sequence in a normally disallowed part of a complex query, so it's a handy function to keep around.
This will iterate once in the generated package specification, and then you could pass that variable value to both the table and post-mapping procedure without any problems.

Master Recipe (C202) getting exact MIC for operation number .

Hi Experts.
i am doing BDC for uploading the MICs in c202 transaction.
I have to add the MIC if that is not existing and i have to change the MIC if that is existing for a particular
operation number for a Recipe . I need to get the link between operation numbers and the MIC for a
recipe .,so that i can check whether the MIC is existing or not.if that is not there, i have to add the MIC .
Please let me know the table relations for getting the existing MICs for an operation number for a recipe .
With regards,
Sharat.

Hi,
I guess you would have created 15 Parallel sequences one each for each Resource. Looks like operation qty split does not work for parallel sequencing operations. Each Sequence shows same number of opertaion qty as of order qty.
Parallel sequences i guess are only maint to perform different activities simulataniously. However same number of order qty needs to pass through each sequence .
Only solution for you is to use Operation qty splilt by maintaining individual capacities in Resourse or to create different process order for each resorce.

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 .
regards

Hi,
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.

Operation number not holding in Operation details screen for WM6.2

Hi Experts,
I have added custom statuses to operation object in WM6.2. When I am editing the operation,Operation number is displaying in operation details screen header.But when trying to execute custom statuses, the operation number is not holding in Operation tile view header as in the below screen snap.
Thanks in advance.Kindly suggest.
Thanks & Regards,
Sravanthi Polu

Hi sravanthi,
Just make sure that when you are editing operation object for custom statuses change you are editing same object that you are seeing in operation details screen.
I think this problem is due to different/stale operation object that is being edited for when you are calling Operation Edit Transaction for change status for (custom statuses).
I recommend to check your Target for Button , Action and Edit Transaction for this (is it same operation object that is being seen on detail screen/being edited for).
