Capacity Leveling Problem
If I have an order that requires 85 hours of production, and the work center responsible only has available capacity of 14 hours per day, how can I divide up the order in a Capacity Leveling Planning Table (CM22)? When I dispatch the order, it automatically overloads the work center instead of spreading itself out over several days. When I created the production order I gave it a start date 2 weeks away from the finish date. Yet in capacity leveling, when I dispatch the order, it only goes to one day and overloads the work center by several hundred percent?
Basically, how can I take this single order and divide it up over 7 days in Capacity Planning?
In both the "strategy" box of CM22 and the "capacity" tab of CR02, I have made sure that the relevant boxes for finite scheduling were checked. However, the system still overloads the work centers. This would mean that there is a 'finite' capacity in each work center and that each center cannot be overloaded, but my work centers still load themselves to nearly 1000% capacity! Why is this? How can I make sure that when a work center reaches capacity, it's quantities flow into the next available slot?
How can I spread the requirements over a period of several dates and not just one?

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.

Routing update in capacity leveling CM21
Hi Collogues,
We have simple production type. Production order with production versions.
16 production lines (work centers) with different rates. 1 operation per routing.
I want to use in capacity leveling CM21 to dispatch planned/production orders on these 16 lines.
The problem is that when I dispatch a pln/prd order in CM21 on a work center nether routing nor production version gets updated.
Your suggestion are welcome.Solution found.
Set for each production version "Production line".
Then go Mf50 switch to graphical planning table. It updates routing when I move planned order over work centers. -
Capacity check problem in Project system
hi,
i have some questions for the Capacity check problems in Project System.
1. if one Person is assigned to diffierent Work Centers, for example, person A is assigned to Work Center 01 under Plant 01, and Work Center 02 under Plant 02, how can i do the Capacity check?
if i want to use A of Work Center 01 in the Project, the System will only check the Capacity of 01, or both of 01 and 02?
2. What is the Pooled Capacity?
Rgds,
Lianghi,
1.Capacity check takes place at plant level itself..
2.Pooled capacity:- This is created separately in [u wil find in PP] and this capacity can be used by different work centers.

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
vst-it projectshi
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.
NLQDear
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 .
Hope this helps

The system could not find any remaining available capacity within the planning period.
things checked:
I checked CM01 and I am sure there are enough capacity available ,the planning period in CM21 is also correct (2011/7/1 to 2012/3/31).I also check the strategy(finite schedule and planning direction checked)..Hi,

Capacity leveling ..strange behaviour
When I try to execute capacity leveling from the interactive screen....On the first click it does not level completely ..it levels couple of periods...may be ...
And after some 4-5 iterations ( 4-5 clicks on capacity levelling button) its levelling completely..that is assigning the max utilisations and removing all teh overloading
Surprisingly this problem is not there in quality eventhough we have the same settings
can yu pls let me know the things that I should checkHi,
Are you using an user defined planning book ? Is it possible for you to exceute in the standard planning book ? If yes, please do so to observe.
Is the problem occuring for specific selection objects ( Products/ locations) ?
Please make sure you are doming capacity levelling and that time , no relevant background jobs are running or users are not working on some of your data objects.

dear gurus,
can any body explains the concept of capacity levelling with t-codes.i already posted the same thread.but i require some more light.if any body explains it will be better for begginers.if anybody is having any doccuments regarding please send to [email protected]
-gunaHi,
The following points will be useful to understand the concept of Capacity Levelling.
Capacity levelling is only relevant for inhouse manufactured products and the existing capacity over load in work center with in a plant can be overcome by shifting the operation performed on the overloaded work center to a future period where capacity is avialable by using CM22
Example :
1) An order consist of 4 opns let us suppose ( opn 10,20, 30 & 40)
2) Opn 30 is being performed on a work center " WC1"
3) Assume Capcity load on this work center WC1 is 150% (TCode : CM05)
4) Shift some of the orders in the over loaded work center to a future period where capacity is available . When we are shifting Opn30 to a future period say 15th october , this opn date will be taken as reference & for all the preceeding operations backward scheduling carried out (ie for opn 10, 20). For all the succeeding operations (opn 40) Forward scheduling will be carried out.
5) Capacity levelling by shifting the operation can be used for MTS items with out any problem. In the case of MTO we should take in to account the customer requirement date while shifting the opn/orders to a future period.

Capacity leveling after order creation
This process covers capacity leveling of requirements from the production process, monitoring the capacity after different periods, and how the system determines the new values for the current order after changes are made to the quantities, times, and dates.
1) T Code CM21
2) Enter the field Plant & work Center
3) Choose Enter.
The current orders whose operations result in capacity loads at the selected work center are displayed. By scrolling through the different charts in the planning table, you can analyze the information provided.
4)For a better view, choose Settings ® Scale ® Monthly period split.
5) To automatically dispatch one or several operations of an order, click the red rectangle in the order's diagram section to select the order and choose .
The order disappears from the order pool and reserves a time segment in the work center section.
6) To manually dispatch one or more operations of an order, select the order in the diagram section, drag it to the work center section with the mouse, and place it in a time period that you select.
7) To deallocate an order, select it in the work center's diagram section and choose .
The order is again displayed in the order pool.
8) To analyze the changes made in scheduling, select an order in the order's diagram section and choose Order.
9) Choose Item and write down the start and finish dates of the operation you selected.
10) Choose Enter until the Planning Table: SAPSFCG001 Finite Scheduling Forw./All Functs.Active screen appears.
11) Drag the order to a valid section in the work center's diagram section. Make sure that you move the order to a valid and defined start and finish date.
13) Select the order in the work center's diagram section and choose Order.
14) Choose Item and compare the new start and finish date.
15) Choose Enter until the overview tree appears.

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,

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
JayantaDear ,
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 .
