Infinite scheduling with capacity leveling.......

Hi there ,
If we go for infinite scheduling & then after MRP run go for capacity leveling ..........
then will we get the same effect as finite scheduling .....
Please suggest me
Regards
Kaushik

Hi Kaushik,
If my understanding is correct, you are asking for the difference between manual and automatick despatching of orders in capacity levelling?
when we set finite scheduling in capacity header view of work center, and run MRP with scheduling parameter 2 set.
In capacity planning the availabile capacity will be compared with the required capacity and the load will be depicted as a graph or in table format. This only gives the load situation against the period.
For this the despatching of order will be done manually based upon the load per day by a scheduler in capacity levelling.
And to add more,
In R/3 finite scheduling is not there and this is drawback and APO was put in front for this purpose.
Can you confirm me whether the system automatically levels the order or despatchs the order in finite scheduling.
Best Regards,
Sendil

Issue with Capacity Levelling-CM25

Hi Everyone,
We use CM25 for capacity levelling.
Issue:
Total Capacity req. = 186.8 Hr
Available Capacity on 01.01.2012 on the resource = 380.2 Hr
Now when I try to dispatch the capacity req. for a planned order manually on 01.01.2012, system distributes the capacity-
Distributed   Period
        5.0    31.12.2011
      23.8    01.01.2012
      23.8    02.01.2012
      23.8    03.01.2012
      23.8    04.01.2012
      23.8    05.01.2012
      23.8    06.01.2012
      23.8    07.01.2012
      15.6    08.01.2012
    186.8
But we want to dispatch capacity say on one particular day or split it onto two different days i.e. 90 Hrs on 01.01.2012 & 90 Hrs on 02.01.2012. Is it possible? If yes, how?
Additional Information-
Capacity Defination in resource-
No. of indiv. cap.   16
Operating time       23.76
Capacity             380.16
Relevant to finite scheduling
Thanks,
Parashar.

Hi Amol,
Thanks for your input.
As I have said I already have Capacity more than what is required.
Capacity Available per day: 380.2 Hr
Total Capacity Requirement: 186.8 Hr
I am trying to know that whether what issue has been raised is possible to solve in Capacity Levelling & How.
We are not maintaining shifts in SAP at present.
Thanks,
Parashar.

SCM230 - Time based Capacity Leveling by decreased storage (Days Supply)

Hi,
Reading through the SCM230 training course on the subject of Capacity Leveling, the manual describes the following functionality:
If you choose Time-Based Capacity Leveling by decreasing storage (days'
supply), the system levels the order with the largest days' supply first, then
the one with the second largest supply, and so on.
Can anyone explain this functionality in plain English and what / where are the parameters etc to influnce it?
Thanks for your help

Hi Marius,
I understand forward and combined forward/backward scheduling in capacity leveling using SNP Heuristics/Optimizer method. However, forward leveling or combined forward/backward leveling does not fulfil the requirement because then capacity overloads (aka SNP planned orders) are shifted in future causing shortage in weeks where demand exist. Business needs a way to shift capacity overloads in previous available buckets, if available capacity exists in previous weeks or months. If sufficient available capacity does not exist in previous weeks then the remaining capacity overload should stay in the week/month where that overload occurs due to excess demand. This will provide business an opportunity to meet demand by finding alternate methods of balancing that capacity overload by either adding capacity (running machines overtime, opening up production on a non-workday) or by outsourcing that overload to sub-contractors. However, neither heuristics nor optimizer method of capacity leveling in SNP fulfils this requirement.

Use of Planning Table (MF50) in Capacity Levelling with Production Order

Hello Experts
I wish to know that is it possible to perform Capacity Levelling in planning table (tcode MF50) with respect to a Production Order ? It is known that MF50 is used in Repetitive manufacuring to do the capacity levelling with respect to Planned orders. But in our discrete manufacturing scenario we want to use planning table to the capacity levelling with respect toa Production order.
Any clue or help pertaining to this will be highly appreciated.
Thanks in advance
Regards
Jayanta

Dear ,
MF50 is does the cacapcity leveling based on mateail -run schedule order (planned order ) where as in discrete manufacturing , when you run the MRP , MRP system assume Infinite Capacity and schedule the order as per your selection in MD02(2,1,3,3,2) and then you convert those planned order to Production order .Here you checkied the Capacity in Production Order level .
In stanadrd SAP , it is not possible to use MF50 for discrete production order.
In discrete order or process order , do the caapcity leveling , there are seperate planning table available based on Over all Capacity Profile and Schedule type .This can be done in following way :
1.CM31-Production Order Wise -Tabular
2.CM23-PO wise -Graphical
3.MC88: Ruf Cut Planning
Work Centre Wise : CM21 -Graphical , CM22-Tabular Planning Table .
Make sure the below set up before you carry on the Capacity leveling :
.Define time profile in OPD2.
Define the strategy profile in OPDB
Define the Overall profiles in OPD0.
In OPJK maintained check capacity with SAPSFCG013 profile for your production order type
In OPU3 , scheduleing parametre s: Generate Capacity , Scheduling Type , Automatic Log ,Start date in Past as per your req.
In OPJU , chekc the contol tab of the scheduleing as per OPU3
In OPKP- Production scheduling paranmeters assing the overall capacity profile -SAPSFCG013 with finte scheduling tick.
Master Data :
1.Materials Master define the Production scheduler and production scheduling profile
2.Work Center - Define the capcity planner group,activate checkbox Relevant for Finite sceduling,on the capacity header define the shift timings,break timings and unit of measure,no of individual capaity, enter formula for scheduling in capacity view.
3.Routing - enter the values for the standard values. Use control key with scheduling.
Hope this will help you .

Capacity leveling. Aim is to have oders scheduled within 1 day if possible

Hi All,
I have a list of 10 prod. orders with same basic/scheduled start/finished date= today
In capacity leveling, if i select a whole list of these orders and dispatch them, i get all orders with start day= today, finish date= today+ x days.
I would like to have orders scheduled with start/finish date within 1 day.
I have available capacity of 4 hours per day. Each order takes around 1,5 hours, thus i can have 2 orders scheduled for today, and so on. This is exactly what i need.
My kind question to you is how to setup SAP in a such way.
NB: If i do leveling for each order one by one, then i get what i want: e.g. order is scheduled within 1 day.
Best Regards,
Andrey

Dear Andrey
Your requirement is, Automatic capacity levelling based on the available capacity.
In SAP R/3 PP module, only manual capacity levelling is available. Automatic is possible in APO.
If the requirement dates are same for multiple orders, system will through all the orders in the same date and it will display overloaded. So manually we need to dispatch the overload to the required date.
Please check the below thread also.

Work schedule display in capacity leveling cm25

Hello,
In our company we have created a work schedule (tcode OP4A) and have associated to a work center (tcode IR02).
However, capacity leveling (tcode CM25) doesn't display the work schedule associated to our workers in the graphical planning table.
Do you have any idea how to solve this problem?
Thank you very much,
Óscar

Capacity leveling, after Deallocate scheduling dates getting changed.

Dear Experts,
I have a issue in Capacity leveling using transaction CM25 - Online. I have created some production orders (using forwards/backwards scheduling) for overloading of WorkCentre's. When I dispatch orders it’s getting scheduled perfectly, but when I Deallocate same orders scheduled dates are getting changed.
Even after deallocation production orders schedule dates should be the same. Can you please help me in this regard?
Thanks in advance.
Prashanth

Hello Prashanth,
From SAP help Date Determination in Dispatching and Rescheduling - Capacity Leveling (PP-CRP-LVL) - SAP Library
The current dispatching data is cancelled. The status "dispatched" of the operation is reversed. The order is rescheduled.
If further operations exist for an order which has already been dispatched, the system automatically carries out midpoint scheduling. If no other dispatched operations exist, the system carries out lead time scheduling.
If order date is in past then it schedules to current date during de allocation if you do not have enter number of past days allowed to start date in scheduling parameters.

Sequential scheduling of orders in capacity leveling

Dear All Hi,
I working on capacity leveling where in the clients want the following requirements, please give your valuable inputs & your help will greatly appreciated & rewarded.
The following is the scenario:
If have 3 orders scheduled on 3 consecutive days (considering each order completes in a single day) then if drags the first order to forward date, then the system forward schedules only the selected order but the client wants order number 2 & 3 to move automatically. That is if I push the first order, then sequentially 2nd & 3rd order should move automatically & gets rescheduled sequentailly.
Similarly it should happen when I drag the 1st order to left then the proceeding orders should simultaneously move along left in leveling screen
Thanks in Advance.

Hi Mario,
Thanks for your reply.
All the 3 orders are independent & are of finished goods. All the orders are scheduled on the same work center. Due to machine break down during the processing of first order, there's a loss of time, so i will select the first order & dispatches to forward date & at the same time i want the 2nd & 3rd order to get resheduled correspondingly.
Suggest the solution for this, Thanks in advance.

Resource scope when performing capacity leveling with Optimization method

Hello,
Can anyone tell me if, when performing the Optimization method in Capacity Leveling for transportation resources production resources are validated? I am currently testing this and I found out that if the capacity variant of the production resource is no 00, 01 or 02 the system will give an error message when trying to level a transportation resource, the message indicates that there is no available capacity for the production resource.
When reading documentation in help.sap it appears to me that Capacity Leveling should only focus on the resource to be level not in other resources and in this case my transportation resource has available capacity that shouldn't be affected for master data errors of production resources...
Could somebody help me clarify this issue?, I have already open a message and they suggested me to change the capacity variant of the production resource, evidently when I do this everything works but I still don't understand why capacity leveling, with Optimization method, of a transportation resources is checking on production resources.
Thanks!
Erika

Hello Ian,
I am not talking about the SNP Optimization Run that is certainly manipulated by the constraints that you update on the optimization profile; in this case "Capacity Leveling with Optimization Method" the constraints are automatically set by the system and what I need to know is if these constraints are considering not only the resource that is to be leveled (in this case the transportation resource) but also the production resource.
Sorry but your answer does not correspond to my request, because you are talking about the Planning Optimization run and I am talking about "Capacity Leveling with Optimization Method".

Difference between finite and infinite scheduling

Dear Frndz,
Pls tell me how the system will behave if I don't select the finite scheduling option for the work center.
Thanks and Regards,
Srini

Finite Scheduling
Scheduling type within capacity planning that takes account of the capacity loads which already exist. Finite scheduling calculates the start and finish dates for operations in the order. It is a detailed scheduling strategy with which you schedule orders and operations, taking into account the existing resource load. A resource overload cannot occur.
Infinite Scheduling
A detailed scheduling strategy with which you schedule orders and operations, without taking into account the existing resource load. It is therefore possible for resource overloads to occur.
R/3 does planning without consideration for capacity situations. So if MRP says you need 500 parts on 3/1/04, it schedules them all to be built at the same time, even though you can only do 100 at a time. Assume you have a fixed lot size of 100, you'll get 5 planned orders for 100 to start on the same day. This is "Infinite Planning". APO would recognize that constraint, and instead schedule out the 5 orders over time. The important part of that is that it also will schedule out the deliveries of the components for 5 different days. This is "Finite Planning".
Now, assume old fashion MRP. It schedules all 5 orders for the same day, and the buyers go out an get all of the components for the same day. Then the planner realizes he can't do all 5, and manually changes the schedule, and manually spreads out the 5 orders. The buyers will recieve rescheduling notifications, but not until the scheduler does the manual rescheduling.
You could call this "Infinite Scheduling", but that only means the same thing as Infinite Planning.
But, SAP has "Capacity Leveling". What that means is you run another program after MRP (CM27 and CM28), which can be run in batch mode overnight. (There is a ton of configuration and thinking that will be required to do this!). The capacity leveling program will recognize the constrant at the work center level, and fill up the first day, then re-schedule the next
order to the next available capacity, then the next order searches for available capacity, and so on. This is called "Finite Scheduling". The problem with this is the opposite of Infinite Planning, which is it doesn't take Material availablity into consideration! The system will re-schedule a production order without thinking about whether the materials will be available
or not.
Finite Planning does Finite Scheduling at the same time. If there is no capacity available on the desired date, the system looks for when capacity IS available. Then it stops to see if Materials will also be available (usually based on the lead-time for those components). If there is a material problem, then the system figures out when the materials WILL be available, and then
checks to see if capacity is available on THAT day, and if so, it blocks off capacity, and allocates the materials for that day
Hope clear to you, other wise pls come back

After capacity leveling dependent requirement s to be adjusted

hi
iam planning a fert product on 30 th agust for 100nos
created md61 -pir for 100 nos
done mrp run at mdo2 and got scheduled dates for 100nos which has gone beyond the requirement date as i was chhosed leed time scheduling and made dependent reqirement proposal for the order operation date.
here the important thing is the work center which i nedd to produce was fully engaged inthe period (schedule period which system proposed) .hence i made capacity leveling and planned order dates were changed again
which are actual producion dates
after capacity leveling my planned order was firmed
my problem here is the dependent requirement proposal date also
need to be changed with respect to firmed planed order.
how to achive this
i tried with opu5
but no changes in dependent reuirement proposal (planned order)
plz suggest
sasikanth

hi
i tried it but unfortunatly it is creating a new planned order and giving exemption messge to the firmed planned oder as cancel the proposal
which is not at all acceptable
means for a single PIR
i made mrp run AND got planned order , after leveling the planned order was firmed
means my pir was satisfied with this
i made mrp run without changing PIR dates and quantity by expecting that it should propose a new dependent reqirement
but system created a new planed order to pir date which sholud not happen.
plz elobrate your view

Capacity Leveling of Work Center

Hi all,
I have a problem with Capacity of Work center (WC).
I have a Internal Activity, and i assigned a WC for this Internal Activity. WC's capacity is 100H/day for 1 number of element.
Work of this WC is 250H, duration 5 days, number of element 1. Default capacity of this WC is distributed by Distribution Key define in Activity. . And they are divided equally between factory days in 5 day. That is capacity requirement is 50H/Day
So, i want to edit this WC's capacity following value:
Day 1: 100H/day
Day 2: 50H/day
day 3: 0H/day
day 4: 0H/day
day 5: 100H/day
How can i do it?? I try to use Dispatch Manually but i cant solve this problem.
Please help me for this case.
Thank all.

Dear
Capacity leveling depends on some of the basic set up of Capacity Requirement Planning .You need to have proper CRP set up frist .
Couple of check points : -
Did you work centre is relevent for finitie scheduling in CR02-Capacity Header and wht is the over laod percentage for work centre ?
Did you have Capacity Requirement Related Set up like Over all profile , time profile , Startegy Profile -OPD0?
Did your Capacity Check -OPJK -Order Control at order level are active for availibilty Check 1 and 2 and assinged Over all Profile ?
Set up :
1.Please assing a operation control key like PP01 where Details Capacity Check and scheduling is active .
2.In CR02-Work centre -Capacity Header -You should have Follow check box marked
1.Releven for Finitie Scheduleing
2.Can be used for multiple Operation
3.
3.OPU3/OPU5 -Define Scheduling paramter -Mark Scheduling and Capcity Check for planned order or production Order
4.In SPRO -Shop Floor Control-Define Production Scheduling Profile -You need to matian the relevent Parameters like
1.Schedueling Automatically 2.Scheduling Log 3.Adjust Scheduling -Basic date , Depedent Requirement date 4.Scheduling Type -Backward etc .
These are all basic level set up beside CRP overall profile and other profile like strategy /time etc which may in place as you are analysing in CM01.
Please find below some of the useful CRP details : Refer this threads which are self explaintory :

How to dispatch operation to do Capacity Leveling at Work Centre Level :
1.Frist Check the over load at work centre . Goto -CM07/CM05-give plant only -then hit the Stnadard view -You will find weekly or daily baiss load ( Requirement , Avaliable Capcity , Overlaod etc )
2.Check the week in which days you are tring to dipatch -if you selet the week check box and double clik it will show u all the dataiul load .Basde on the available capacity in other week-days u need to dipatch in CM22/CM31 or CM25/CM21
While dipatching in CM22/CM31-Select the Stragegy button on the top header -Mark Date entry when dispatching so that when you select the operation of any production order or planned order for certain work centre , it will pop with window having information of Date , Work Centre , Time .Onec you did this you will receive Scheduling log with certain information .

How to run mrp and capacity leveling through heuritics.

Hi,
How to run mrp and capacity leveling through heuritics.
What are the setps required for production planning run this thing in the heuritics in pp/ds?
Regards,
Sunil

Sunil,
APO PP/DS doesn't have a 1-to-1 match for MRP/Cap levelling per se. There are, though, a limitless number of ways to achieve the results you want.
Start with a basic PP planning MRP - SAP_PP_002, which will should create all necessary planned orders
Then try a DS heuristic to schedule your orders according to capacity. Schedule Sequence SAP001 is a good starting point. This can be used to schedule your cap relevant work centers such that they fully load the capacity available, similar to cap levelling.

Capacity leveling problems

I have some troubles with implementing capacity leveling. I cannot level with planned orders (cable solution), so it is only possible to plan production orders.
The setup matrix is used (because setup times can be greatly reduced, depending on the succesor).
For some operations, simular machines can be used. CM21 (work center view) is used. Version: R/3 release 4.6C.
Now a couple of problems rise.
Problem 1:
Since there are simular machines, normally production versions are used for capacity leveling. However, we have to level with production orders, so production versions are not applicable.
Making one workcenter with different individual capacities is also no solution, since SAP messes up with setup times then (i.e. two operations of different production orders have to leveled onto the work center. Normally, the setup is 20h, but if it is a right succesor, it has to be 0h. This is mentionned in the setup matrix. If we dispatch now with a specific strategy for setup time optimization, only one operation will have setup time and the other operation will be schedule from the start on of the other operation's setup... In reality, two setups has to be done, since there are two machines!).
Alternative sequences is also no solution. While leveling, the alternative sequence will never be used by SAP, in my view.
Problem 2:
The strange logic of SAP: setup of the next work center can only be done if the production on the previous work center has finished. In reality, the setup of the next work center can overlap with the production of the previous workcenter.
Besides these two problems, there are some more troubles with capacity planning in SAP. SAP messes up sometimes by putting the setup time before the wrong operation (sometimes, the first operation has no setup time and the second does. However, this should be the other way around.).
If you plan an operation manually, SAP doesn't take into account the setup matrix.
Does anyone has a solution?

Hi Walravens,
What i have understood is, u have the avilability of multiple resouces to produce same material, if any capacity bottle neck, u level the different production order of same material from "one work center" to "another workcenter".
At cm21, select the mutiple workcenters (selection criteria) and dispatch the operation as need.
For setup time overlap, how to system know ur producing two operations (from two different orders) with same setup.
Even the operations from same production order, system consider the set up time of the second operations unless u define overlap function. . Am I understood your problem in correct way.
So remove the set up time for second operation and dispatch.

Pradeep
