Capacity Vs Scheduling

Gurus,
A very basic one.
In Work Centres, both the capacity view & scheduling view have similar formulae (such as setup & process time etc.)
Pl. let me know application wise, what is the difference between both the views(Capacity & Sheduling).Is there a need for both of them simultaneously?
regards,
K.Kumar.

Hi Kumaran,
capacityview:
Normally here we will give the available capacity of work center for ex: say Lathe. Here in this view initially we will give the formulae to calculate the cap requirements , then system will ask about the availbale cap of that perticular work center i.e., its cap utilisation, no of ind capacities, time....etc. During production order creation , due to the help of these formulae that u specified in cap view of work center , system will calculate cap requirements. This u can see in T-Code CM01.
Scheduling view:
Normally here we will give formulae to calculate operation start time and operation finish time for routings.
This view is used only for scheduling of operations.
Hence we will give respective formulae in above two view for cap req calculation and scheduling of operations.
Hope clear to u.
Regards,
Imran

Capacity in scheduling agreement

Hi,
The documentation says we can assign transportation capacity and vendor capacity in scheduling agreements in ECC. Can you tell me which field in scheduling agreements are related to transportation capacity and vendor capacity?
I am new to scheduling agreements so please be a little elaborate.
Thanks.

Hi,
For all of your queries;
ME01 - Maintain Source List for the materials
Here maintain, Vendor, Plant, Purchase Org, most important input Scheduling Agreement No in Agreement column and in "MRP" column, use "2" i.e. Record relevant to MRP. Sched. lines generated automatically
Now run MRP and observe the result, it will consider Scheduling Agreement in MRP.

Remaining capacity requirements scheduled for operation in Planned Order

Hi all,
I'm workig with planned orders, and I need the "Remaining capacity requirements scheduled for operation" data to list it in a Z Report, but I don't know how to get it.
You can see the info in the "Detail Scheduling" of the planned order in MD13.
Anyone knows how to get the info? Any table or any FM to get it?
Points will be given for helping
Thanks in advance!

Did you ever find out where the planned order capacity information lives? I can find the production capacity information in table KBEZ, but it appears that there is no planned order info there.
Thanks,

Pooled Capacity in Scheduling

HI All,
I have created the independent capacity and activated as pooled capacity which is a group of labors,
Now I have the Work Center which is a machine work center, this group of labors are used in diff work centers, so I assigned them to these work centers in capacity Tab of WC.
I have capacity formulas assigned to Machine capacity and pooled capacity is assigned to labor capacity which is created in WC,
Do in need to assign this pooled capacity in Scheduling tab, using Capacity category as Person ?
OR it is sufficient to assign pooled capacity in capacity tab page?
In my scheduling, part I wanted to have scheduling on the maximum time consumed in operation. But in planned order scheduling tab, I cud see both machine and labor.
Where am I getting wrong.
Please suggest
Regards

Hello Mr. Bramhnakar,
Thanks for your reply,
Yes i have tried the settings you mentioned.
My doubts are :
Should the Pooled capacity be getting calculated in Scheduling.
Since I gave capacity formulas, for both capacities in Work Center,
and scheduling formula in scheduling tab.
In routing i gave 12 Hr machine and 16 Hr in Labor (Pooled),
In Planned order, I can see the Both Taming, But after converting it to Prod Order, In Operation details tab->dates, i cansee the scheduling on the Machine Time, for which i gave formula in WC--Scheduling tab. This is confusing for me since in Planned order i cud find both but in Production order i found One,
In Routing i have activated Req. Overlapping.
One more query sir,
Is their any problem if i use Splitting indicator with count of available capacity in WC,
I did this bse the all order were followin in diff dates.

Raghu

Regarding workcenter capacity and scheduling

Hi Experts,
I have created a workcentre and maintained all formula's for each activity in the workcentre.Now what I want is that, while confirming the activity , If workcentre gets overloaded beyond tolerance limit then it must issue a warning message and wont allow us to confirm that much activity.
Case 2:
If capacity is overloaded then the timeframe also should mave accordingly as automatic scheduling.
your valuable suggestion would be highly appreciated
Regards
Ashutosh Saraf

Hi,
Work center capacity and activity confirmation both are different entities and this is what I guess. Please correct me if wrong.
Let me put it this way...
Work force is assigned at work center level which let you know the total capacity being maintained at referenced work center. If some one asked me about what is the capacity of work center A, then my reply is 64 hours/day (10 persons with 8 hrs each and performace 80%). Thats how we derive the capacity of WC.
Now coming to Activity confirmation: for example you have planned hours of 100 on NWA and keep confirming periodically. When you cross the limit of planned 100 hours system gives a warning that activity is already confirmed (I mean reached 100% of planned work) but still allow you confirm beyond planned hours.
In combined view of WC and NWA, system never gives any kind of warning message even if you going beyond the planned hours on NWA.
As Mahendra pointed out, capacity evaluation and levelling being done manually and there is no automated process available unless you have developed program which takes care off.
Case2: Capacitiy overloaded or underloaded, capacity levelling to be performed basing on available capacity at work center level by manually.
The time frame adjustment (I assume you are talking about automatic scheduling), if activity confirmation is less than the planned distributed value, whenever system schedules automatically and let you know ETC (Expected time of completion). for that you have to select the automatic scheduling check box at NWA.

Sudhakar

Different tabs and formula in workcenter for capacity and scheduling.

Dear All,
I wanted to have a logical explanation for why we use different formula for capacity req calculation and scheduling.
why we need 2 tabs for this in work center.
As per Std SAP formula, except the tick of capacity generation and allowed for scheduling in customizing.. rest is same.
when we level the capacity also ultimately we are scheduling the operation or order.
Thanks
Regards
Raghu

Raghu,
The amount of capacity consumed is not always the same as the schedule. You have to allow for the times when the formulae are different.
For instance, consider the case when you have multiple capacities, and you practice order splitting. The formula for capacity might be Machine time * operation quantity / base quantity, but the formula for scheduling might be Machine time * operation quantity / base quantity / number of splits.

Planned order based capacity planning

Dear Guru's,
Is it possible to view & analyse work load on work centers for planned orders in R/3? Please let us know the settings to be done if needed.
Regards,
SAP CONS

Hi,
Yes it is possible to view and analyze the work load on work centers for planned order..other than standard configuration settings and master data set up no separate settings required for this....still wait for the answers from the other forum experts.
Ensure while doing MRP run on MRP control parameters use option 2 for scheduling as shown below..

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 in maintenance order

Hi,
My PM consultant wants to create a maintenance order of 5 coaches of a train which needs to be repaired. he wants to send these 5 coaches to a repair line where repair work has to be done.
Now I have created a work centre whcih represents the repair line with machine category.This work centre is used by the PM consultant in his maintenance order. But this does not generate any requirement in CM01 or CM21/ CM31.
Is there any mistake in my work centre? Is there any customizing required from my end? Do i need to create a production line instead of work centre?
Please reply.
Regards.

Hi,
you need to define the formulas for the processing time in capacity and scheduling tabs in work center. Then you need to maintain the standard values in your routing. You need to configure the scheduling parameters using the T-code OPU3, OPU5. Then while running MRP you need to run lead time scheduling, then only the system will create the capacity requirements, then only you can see this capacity details in CM01.

Customization needed for capacity setting

Hi all
I cofigured the work center (Shift defination,shift sequence,break time)
I have given for one shift there is 21 hours capacity available (as for three machines
and each machine working 7 hours per shift)
But when I check in t-code CM03(Capacity Planning in Standard Overview it is given only 21 hours per day but it should be (63 for three shifts i.e per Day)
Why it is any costomization needed . Pls provide solution
Hoping for reply
Dev

Hi Dev,
Ultimately system would consider what you see in the "Available cap profile" in your work center master from Capacity view.
The below are main functions in Capacity and scheduling
One is the Capacity availability check - Here the systems checks just for the available capacity, i.e it will only consider the available capacity maintained in the interval available capacity, if its not maintained there, then system would check the available capcity profile. Once systems finds that capacity is available, system would reduce the available capcity once the capacity is confirmed. And available capacity profile is updated automatically by the system once you change the header or the interval available capacity
The second one is detailed scheduling 
- Here the system does scheduling . The shift sequence plays a role here to give precise timing.
The third one is Capacity levelling
This is the one is where you precisely allocate the work centers or resources via planning table - Here the shift sequence and availability check both are considered also system would block particular work center for the dispatched dates and times.
Hope the above clarifies.
For your requirement, you need to make sure that 63 hrs is shown by the system in the Available capacity profile.
Moreover, interval available capacities' function is to override the header data and Hence always this would have higher priority. System also would show this data in available capacity profile populated automatically.
Please get back to me if you have further clarifications

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.

Regarding scheduling dates & time

Hi,
1)i have created a production order for a finish material "A" mentioning finish dates 21/05/08.
2)order qty is 100 kg's time taken is 1 hour( i.e. 24:00 to 23:00).
NOW,
3) when i create the production order for the same material "A" again, for the qty 200 kg's & finish date is 21/05/08.
4) finish time is taking from 24:00 instead of 23:00.
Actually it should start from 23:00 right????
i think i missed out some settings.
i need all of your suggestions for the above problem.
thanks/regards
vish

Hi ,
Scheduling depends on the option you select on MD02 screen , if you have selected Determine basic dates then it will search In house production time mentioned in material master . If you select 2 nd option i.e lead time scheduling and capacity planning then system will refer routing ( cap requirements will also be created ).
R/3 does not consider capacity while scheduling the order so check either in house production time or from routing check scheduling results for 100 or 200 quantity .
Reward if useful .

Required capacity calculation in cProjects automatically

Hi
For a project, in the structure tab tasks have been created and role/responsible person has been allocated with duration.
In the resoruces->staffing tab, the requried capacity is still shown as zero.Also in resoruce->tasks tab, tasks assigned to project role is not getting popualted automatically even though these details are alsready in the structure.
Should we have to redo the task/capacity assignment manually again or does cProjects do automatically from structure? Any help?
Regards
Senthil

Hi,
The capacity requirements & scheduling is done as per the formula given in the capacity & scheduling tab page in the work center (cr02).
In work center the standar value is maintained , this contains the parameters (eg: setup, machine time etc.) to be used in the formulas.
You can define the parameters using t.code op17,
Standard value key using op19 & Formula using op21.
Then when you create a routing, when you enter the corresponding work center in the opetation details, the system will ask for setup,machine time etc.
Here you can enter 10 min as setup time & no. pcs which can be machined/processed in one minute.
Then when you create a production order & if it forward scheduling, then the system will start scheduling from 6.00 am say the start of the shift.
6.00 to 6.10 am setup will take place & then from 6.10 machining will start. Then end time is determined by the Order quantity.

Senthilkumar

Scheduling in OPM
