Setup Matrix volume Doubts
Hi experts,
I have a couple of questions concerning the setup matrix volume.
1-a)What setup matrix combination volume is considered as acceptable?
b)Which is the break point from where performance issues take place?
3-What happens if the optimizer is optimizing orders and within those orders , there are features which are not included in the matrix.If this eventuality occurs, how the optimizer reacts?

Thanks a lot for your advise Frank!!
Question Still pending review:

Hello All -
I have 3 products A,B and C which are run on a single line during a particular week(day). We have certain set-up times when we move from one product to another. Here are the set-up times:
The sequence in which these products run on the line is decided by the plant scheduler during production planning. The production planners run heuristics and peform manual changes to the planned orders. They know which product runs in which shift but they do not necessarily adjust the planned orders to the hourly level.
What we would like the system to do is somehow incorporate the set-up times when we move from one product to another. We would like to see the the resource being consumed during the set-up time.
Also, we are not in a position to use the optimizer. So any solutions involving the Optimizer are out of scope. Just want to achieve this using heuristics.
To achieve this, I have created the following master data:
1) Created 3 setup groups SG1(A), SG2(B), SG3(C).
2) Created a setup matrix SM1 and set up the transitions for all the above combinations.
3) Assign the setup group to operations in a ppm
4) Assign the setup matrix to the resource
I then created 3 planned orders in production planning for the SAME day. All 3 have the same availability time 23:59:59 and based on run-rates we have different start times.
I have the following questions:
1) Which DS heuristic should I use to adjust the start times and the end times of these orders by considering the set-up times in the setup matrix?
The resource should basically be consumed during these setup times. I have looked at "Reschedule" function in the DS planning board but I get an error when I run this. Please see end of this post for the error. The message says I may not have free capacity, but I do. I am using backward scheduling and infinite.
2) Is there anyway the set-up times/matrix can be considered during production planning itself and not during detailed scheduling?
3) Can the option of "Schedule Sequence" work for my scenario.
Appreciate all your help.

Error during scheduling
Message no. /SAPAPO/OM043
Diagnosis
The system could not schedule an order, operation or activity.
This could have the following causes:
The resource does not have any free working time or capacity.
If you have set planning direction backwards in the strategy profile:
There is not enough working time or capacity available for scheduling between now and the scheduling date.
If you have set planning direction forwards in the strategy profile:
There is not enough working time or capacity available for scheduling between the scheduling date and the end of the planning area.
If you plan characteristics-dependently:
You have assigned characteristics to operations of the order that do not agree with characteristics of the resources on which the operations are to be processed.
The system cannot find any suitable characteristics on the resources and so it cannot schedule.
Procedure
Depending on which of the above reasons is the cause, change the following settings:
Change the working times and capacities of the resources.
Set the planning mode "infinite planning" in the strategy profile.
Activate the planning direction forwards or backwards and reverse in the strategy profile.
Change the characteristics that you have assigned to the resource.Thank you all -
It was a mistake on my part. I was supposed to create a new "set up" activity before processing activity and make that relevant to set-up. I had the processing step checked for setp all this while. Now its working.
Thanks

PPDS: I have a setup matrix in SAP ECC 6.0, and want to transfer the same to APO using Core Interface. Has anyone done it before?
Hi Subhash,
Please open this link to see the details:
http://help.sap.com/saphelp_scm70/helpdata/EN/89/bd3e42ce98033be10000000a1550b0/frameset.htm
You perform the data transfer in the following sequence:
Plant
Setup groups
Work centers
Routings
You check the setup groups in SAP APO.
You create the setup matrixes in SAP SCM.

Document for PPDS Optimizer Setup Matrix
Dear All,
Can I have a document or an implementation guide for PPDS Optimizer Setup Matrix?
I have already checked the SAP help and Certification Material about this topic. But there is no more information on this topic. It will be great if you provide a document where I can learn from the scratch.
Thanks a lot.

Scheduling using Setup Matrix in PPDS
Hi Gurus,
We are using PPDS Steup Matrix for scheduling orders. We have scenario that from product A to B, there is a changeover. And after producing A or B for certain hours, there is a cleanout of certain hours.
Ex- Orders A for 5 hrs, B for 5 Hrs. Setup Matrix: A-B=1 hr and Max order ( A or B)=7 hrs after which cleanout should happen.
While scheduling , A(5hrs) (Setup) B( 5 hrs), this is acheived.
But result should be A(5hrs)(Setup)B(2hrs)(Cleanout)(B 3hrs)
Please give your valuable inputs. How to map extra Cleanout ??/ Should we ceate another setup matrix for cleanout?? Can system take multiple setup matrix???
thanks,
PriyaHi Priya,
I think Your case can be achieved through campaigm planning.
Create a setup group 'PROD' in ECC.
Under setup group 'PROD' maintain setup keys as 'A' & 'B'
Assign these setup group and setup keys in master recipe.
Maintain the same setup group & keys in APO also and than CIF PPM.
Maintain the setup matrix and assign it to resources
Create a campaign profile for 'PROD' with no of chargers(Orders) as 7.
Now schedule orders by using optimization.
After that create campaigns by using campaign heuristics on the resources.Campaigns will be created for every 7 hours.
And then create cleanout order by using cleanout heuristics between campaigns.
By this you will achiece setup between products and change over after your max run length also achieved by cleanout order between campaigns.
Hope this is clear.

Hello All,
Can a setup matrix be used in combination with a PDS? I created a setup matrix and then went onto to create setup transitions and found that it is only configured to accept and PPM Plan and not PDS. Is this how it is or am I missing something completely?
ThxHi Vishy,
There is no rule which prevents usage of PDS for set up matrix.
You can very well use PDS data with set up matrix.
I hope there will be some configuration missing in your set up
to generate the required scenario.

Same setup matrix for both fert and halb products
Hi,
at present we are using a setup matrix in apo for fert products, which is built on the setuptimes/groups of the halb products.
can i use the same setup matrix for the halb resources, if we want to use the sequence dependent setup planning for the halb products..our fert is the combination of halb and packing..
Thanks,replace the existing rules with one that does not specify the port [L3 rule].
However, you can't use arrowpoint cookie anymore.
And you can't use 'advanced-balance ssl'.
Another solution would be to use an SSL offloader to decrypt the traffic and have the cookie inserted in the https traffic as well.

Where to assign setup matrix ?
Hello to all SAP Expert,
I have one problem regarding setup matrix assignment. I have created setup matrix, but where to assign this so that I can reduce my setup time required.
Thanks in Advance.
Regards,
YogeshDear,
Set up group and transition matrix :- Setup group key is defined in the operation in the routing and then the transition times between setup keys is maintained in configuration. in work center CR02 default value tap you will get field for Setup Type Key.

Extending the setup matrix use
Hi
we would like to extend the setup matrix use for the halb products now, currently we use the setup matrix for the fert products and it works fine. our fert = halb+packing, when extending the setup matrix use to the halb products what changes need to be done.
do we have to create a new setup matrix for the halbs or..can you pls share your ideas..Hi, its advisable to create a new setup matrix for the halb product.
Ensure all the w.c on which setup sequencing is to be done are single mixed resource.
Assign the newly created setup matrix to single mixed resource
In the routing assign the setup group
Re transfer your PDS
create a test planned order in APO rrp3 and test if the setup group is arriving or not
You ca use the existing sequencing heuristics

Hi all,
We are able to sequence based on setup groups using heuristics in PPDS (either ascending or descending manner) but setup time is not getting picked up during changeovers from one setup group to other, as per setup matrix.
Any suggestionHi,
kindly post your querry in the ERP- SCM to get quicker response.

Hi Gurus,
Please brief me on the significance of setup group and setup matrix in APO and the effect of the same in planning?
Thanks,
PrasanthHi Prashanth,
Setup group tries to group products with similar characteristics.
Setup matrix provides the sequence in which the set up groups
can be executed.
Setup sceanrio is used in cases where in the time taken for switching
over from one product or group of products or category of products or
charactersitics of products which is called as predecessor to another
product or group of products or category of products or characteritiss of
products which is called as successor.
Say for eg, if you are having a scenario wherein
you need to manufacture products with low weight,
medium weight and heavy weight products.
You can define in the set up matrix that for switch
over from low weight to medium weight products for
manufacturing, the set up time involved in 2 hours and
the setup cost involved is Rs.100,
Similarly, for switching over from heavy weight products
to medium weight products, the set up time involved
is 3 hours and the set up cost involved is Rs.50.
Based on this information, system will frame a matrix
of information and use during planning.
Hope this information is clear to you.
Please confirm whether your issue is resolved.

We are using repetative manufacturing, I want to know if I can group all materials by set-up time - hence reduce change overtimes from one group of products to the other.
Can I use Setup group category & setup group Key with planned orders.
Thanks in advance.1.Set up grop key and categroy will not help in the REM manufacturing table.
2.This setup group and matrix will help in the capacity planning only.Where dispatching can be done by grouping at the setpu group key etc.
3.Even that would complicate the things becuase again we need to check what things system has pushed.
4. But int he capcity planning table -graphical it can belp you to highlight the order by the setup grou key .
5.So if you are looking for a funcitoanlity of grouping the materials in the setup group then that is not possible.
let us know if you have anydoubts..

Volume setup and volume limit password setup
Here is my problem, My Ipod has very low volume. I tried using the various EQ styles but its still low in very volume.
I tried the volume limit adjustment but I have no password and it never gave me a chance to make changes. When I entered a four digit of a new password, it just blinked green and no chnage happened.
Thanks in advance.If you forget the combination, you need to restore the iPod.

Hi experts,
We are working with Characteristic depending planning (CDP) together with setup matrixes based on characteristics.
First, we run an heuristic process that organizes the operation sequence .This is followed by the optimizer execution. The optimizer run lasts 5 minutes. However, the results obtained are not adjusted to the ones suggested by the matrix.
Unfortunately after the optimizer run, a manual adjustment must be done followed by a next run. This activity must be iterated until the desired result is reached.
I need some advise cause I need to clarify some doubts.
-Are the optimization results linked to the execution duration?
- Is it usual to make manual adjustments?
Regards,
Analía Nahmíasthe optimizer results are of course linked to the calculation duration. the longer the better the results. you can enter a maximum run time in the optimizer profile.
general recommendation: 500 activities = 1 minute
if you increase this the optimzer will create more iterations and will get closer to the objective functions minimum.
it is unusual to adjust optiimizer results manually because any manual interaction destroys the optimizer result. it is like scales which have been delicately balanced with a lot of small weights on both sides. if you manually move one small weight to the other side the scale is out of balance.
If you work with set up matrices I recommend to check the set up costs and times of the transitions again. this is what the optimizer uses to schedule the activities.
for the optimizer, setup times and costs from the setup matrix are interpreted as follows:
in objective function:
setup costs = 10 is comparable to a setup time of 10 seconds
setup costs = 1000 is comparable to a setup time of 16 minutes
Use grouping functionality in the setup maintenance to group setup keys: Define setup groups and setup keys.
Do not just put everything in one big setup matrix using only individual setup keys. -

Not sure if this will help, but I think you can use a mic to do a voice over. You can use the line in option when setting up the voice over. But you must have a quarter inch jack on the mic.
