Functionality of APO SNP capacity levelling

I am using APO V5.1 SNP capacity levelling.
When capacity levelling runs on a given resource and tries to move planned orders, does it respect the relevant lot size parameters defined for a product?
Thanks for any advice on this...

Hi,
In APO SNP , Capacity leveling takes into account lot size data that is defined in the master data(Product Master) with following restrictions:
It takes into account fixed lot sizes, maximum lot sizes, and minimum lot sizes.
However, the system does NOT considet period lot sizes or lot sizes from PPMs/PDS.
Further to the above, the capacity leveling method that you choose controls the way in which the system takes into account lot sizes.
If we choose heuristic-based capacity leveling, the system uses the same rules as for the SNP heuristic when taking lot sizes into account; and
if we choose optimization-based capacity leveling, the system uses the same rules as for the SNP optimizer.
Hope this gives you insight.

APO SNP capacity levelling heuristic

I am using APO V5 SNP.
I have a question about SNP capacity levelling heuristic.
As I understand it, the heuristic works on a resource by resource basis and will aim to capacity level across time buckets.
But suppose I have a product which has two different sources of supply (PDS/PPM) using different resources X and Y.
Suppose the capacity using resource X is overloaded for week n, but resource Y is not overloaded.
Can the levelling heuristic be used to move capacity from resource X to resource Y for week n, or would this have to be done manually via changing the PDS/PPM?
Thanks,
Bob Austin, Atos Origin

Bob,
You can move the load from X to Y if Y is an alternative resource to X. This can be accomplished by going to the capacity levelling button and then in the options check the box for 'Consider Alternate Resources'. After that you can mention muliple alternate resources also to be considered.
Hope this helps.

Use of BADI for SNP capacity levelling

I am using APO V5.1.
I'm interested in using the Business Add in (BADI) for SNP capacity levelling.
Can anyone tell me which BADI this is, and the possible functionality it can provide?
Thanks for any information on this...

To give you a couple of examples of what we use the BADi for:
1) Based on a product characteristic, the levelling will only level certain products. E.g. you could set a characteristic to mark products for internal use versus export use and then level the internal requirements first.
2) The levelling will only level planned production for highlighted orders in the data view.
Hope that helps for ideas
Regards
Ian

WORK FLOW & PROCEDURE FOR FOR SNP CAPACITY LEVELLING HEURISTICS RUN

Dear Sir / Madam,
Currently, we are taking only SNP Heuristics Run and the output viz. planned stock transfer requisitions are being passed to PPDS as such. But now we feel, SNP capacity leveling can play a vital role in getting more fine tuned results from PPDS. So, We wants to start using the SNP Capacity leveling run. We shall like to know the work flow / procedure for taking the SNP capacity level run i.e. what inputs should be properly reviewed before taking the SNP capacity level run and what shall be its output..? Kindly let us know the procedure / work flow for taking the SNP Capacity Levelling Run.
Your early reply in this regard shall be really appreciable.
Thanks & Best Regards,

Hi Sanjeev,
as in any other module, correct master will play a key role in getting effective results in capacity levelling. you will need to check the following master data while setting the system for capacity levelling :
Consistency in BOM in R/3 and PPM/PDS
Consistency in Routing in R/3 and PPM/PDS - the actual through put on the shop floor should be the same as that in the routing and in the PPM/PDS. unless this is in sync, no amount of levelling can return good results.
Maintenance of shift - again as present in the shop floor.
you can provide the dump of the above master data and ask the shop floor engineers to validate the data as it exists in the ssytem. you can do the consistency check between R/3 and APO yourself using queries. Once they have validated this master data and the the actual master data reflects in your system, i think, the job is more than 50 % complete.
also you need to check the lot sizes, rounding profiles, and period factor, becasue all three combined play a major role in giving good or better results after levelling.
you may also check at what level you want to run the levelling. whther the bottleneck is at the finished component level, or 2nd level, etc. you may check whther you have discrete manufacuring or REM and if you really want to levelling on REM order.
then you need to analyse, what is the lengh of horizon you want to run the capacity leveling on. sometimes it makes no sense to run on the entire horizon because if capcities are already overlaoded, you will not achieve the desired results.
hence depending upon the level of your understanding and comfort of the planner (who will be using this result), the horizon can be increased grdually.
if you are starting to implemement capcity levelling, you can sumulate runs and show the results to the planner and check if the standard capacity heursitics satisfies their requirement. else you can go for custom requirement.
you will also have to decide on the stratagies, priorities,etc based on the business requirement.
i think the above should give some starting direction to implement capcaity levelling in your system.
award points if you find this useful.

SNP - Capacity Leveling question

Hi All:
I am trying to do Capacity leveling in one resource and for one material.
After CIFing the material, resource, location and BOM (PDS), I entered some forecast for the specific material in DP and released it to SNP.
Then I ran the product heuristics and when I looked at the planning book 9ASNP94 and Data View SNP94 I noticed that the capacity utilization where more than 100 % in some periods.
Next I executed the 'Capacity leveling button'. and entered the following parameters and executed.
Combined Scheduling
100 % max util
Product priority
Ascending
Heuristics Method
All Relevant Resources
In the Log checked all the three options
The log comes out as follows:
Green status on Resource and Parameters
Yellow status and 'Resource xxxx not used in any PPM/PDS'
Red status Resource utilization
I checked the PDS for the resource xxxx and i found it to be there.
When I go back to the Capacity view the leveling has not happened.
What am I doing wrong? Pl. help.
Thanks
Narayanan

Hi Narayanan,
I think there should be any issue. I hope You selected the data view snp94(2), and loaded your resource in the planning book. then You executed the 'Capacity leveling button' in the planning Book, Right? Try without checking the 'consider alternative resource' check box, and dont give any priority in your capacity levelling profile.
Thanks,
Satyajit

Error /SAPAPO/TSM227 in APO SNP capacity view

I am using APO V5.1.
In an SNP capacity view (copied from SAP standard 9ASNP94 view but modified with some bespoke key figures), I have error /SAPAPO/TSM227 (Key figure not available for selection) when I do the following:
- open the view
- select a resource
- drill down by product (or by dependent objects, by product)
- save
Can anyone advise on the cause and correction of this error?
Thanks...

Hi,
This error is due to missing keyfigure assignments in some aggregtes eg 9AMAPR,9AMALO,9AMALA.So make sure that
you assigned the kefigures to aggregates correctly .

Capacity leveling - Priority logic

Can anyone explain the logic of SNP Capacity leveling order prioritization when set with No priority?
I have tested this with No priority, but the system is applying priority by order size on the net demand in a bucket (considering demands not fulfilled in backward propagation).

My question is about the capacity leveling profile that you define in SPRO / main menu / during leveling in planning book. In the profile, we can define one of the following for priority
- No priority
- By order size
- By product priority (from product master field in SNP2 tab)
My question is related to the first option of 'No priority'. When using that option 1, system behaves as if option 2 (Order size) is chosen. I want to know the standard logic that should be applied by the system.

Capacity Leveling in SNP SCM 5.0

Hi,
I want to use the SNP heuristic followed by capacity leveling in order to enable my customer to check capacity requirements in terms of machine and people resources. The particular requirements are:
1. no backward/forward capacity leveling
2. level the capacity across alternate resources
I don't see how I can do 2 without doing 1. I haven't seen a parameter about the number of days allowed in backward/forward leveling (which I would set to zero or to a low number e.g. 2 days)
Best Regards,
JL

I dont think you should be using the standard capacity levelling functionality at all if you are not going to level it forward or backward
What you need to think of is planning using Aggregated resources.
In a nutshell you creatae new header resources that are of capacity equivalent to your resources plus alternate resources
Do SNP plannign on the aggregated ( header )resource
Level or trim any excess capacity requirements (levelling wouldve done this for you but you got to specify the direction)
Disaggregate to the member resources based on some disaggregation rules (or you can customize this)

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
Mark

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.

Jagjeet.

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.
Re: Triggering Finite Scheduling

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 log showing duplicate information for Resource

Friends,
Need one help.
When I am looking into the Capacity leveling logs, I see duplicate information for every Resource. There is no difference in the information regarding resource utilization (before/after). For every resource we are getting this duplicate records in the logs. Sometime there is one difference on timing, (when the resource was processed by the background job.)
Text . Details . Current Date . Time
Resource W10_U0JA_001
Parameters
Resource utilization
Resource W10_U0JA_001
Parameters
Resource utilization
There is no difference in details resource utilization, yet resource are shown two times, for every resource.
We are on SCM 7.0 . Is this standard? if so, then why?
Can you please share your opinion/thoughts. Thanks a ton.
Satyajit

Hi Satyajit,
This can happen because of resource setting in APO.
You need to check the following:
Bucket definition
Resource utilization
Time Zone
You should check also the "Time-Cont Capacity" tab details where start, end and break time is maintained,
You should also verify the "External Capacity" Tab data
There is no other reason apart from that.
You can also check the PPMs which are using this resource and some setting in PPM modes and other operation data.
If it is okay then possibility you need to check the model and version assignments.
You can remove the version assignment and delete the resource and again CIF it to APO.
Possibly it will help.

Vishal

Capacity Leveling - CM22 - Question

Colleagues,
We are using CM22 for performing capacity leveling functions.
1) In the standard system the Total capacity requirements (First column), are updated based on confirmation. We noticed that
only confirmaton yield is posted, the capacity requirement is deducted. However, we would like to know if capacity requirements can be deducted, just by confirmin the operation hours alone.
2) In the standard system, the Total capacity requirements incudes all the time buckets against an operation and sums it up as requirement. Therefore, if you have setup time, processing time in an operation both are added to the total capacity requirements and displayed. We would like to consider only processing time and not include setup time in to the total capacity requrements field.
If any of you have modified the total capacity requirement field on CM22, I would appreciate your thoughts and inputs on how to go about doing this.
Thanks,
PKV

Hi, I didnt get your 1st question correctly. please elaborate.
For point No-2, From a business prespective if you dont want to capture setup time in ur capacity reqmt, then you should'nt be entering the same in the work center. For some of the clients we have used only process time so that we can plan actual capacity reqmt. But in those case, the setup time was negligible when compared to process time.

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
