SNP Optimizer with PDS

Hi Guys,
Is it possible to use SNP PDS with alternate mode for SNP optimizer in SCM 7.0 , If it is not possible then how to create many SNP PDS if there are alternate resources assigned for the product.
Thanks and regards
Thamizh

Hi Thamizh
You can not create SNP PDS for alternate mode.
You need to create different production version for alternate Mode. Only that way you can send SNP PDS.

SNP Optimizer With Runtime Errors

I am Trying to run SNP Optimizer.
The actions performed on SNP Interacive planing book is Selected the Product Locations in Selection window and When trying to load data or click optimizer it is giving a runtime error.
The Error Says: A table is refered to in a SAP open SQL statement that either does not exit or is unknown to the ABAP dictonary.
Table involved is /SAPAPO/STOCKANC.
Please , can anyone help me understand. What the error is and how to go about it?
That would be a great help.
Thanks
GAyatri

Hi Gayatri,
Very first check is already mentioned in the error message.
Did you check that the table "/SAPAPO/STOCKANC" exists in your system? When you would dispplay the table in SE11, you should see against the table name that it should show up as "active".
Click on "check" and then "activate" button if the table is not active. This would make it active.
Alternatively take help from your ABAP colleagues.
(Table should have a description "Key and Descriptive Data for Stock". You should also try to find out if recently some OSS note was applied which is causing this kind of issue)
Thanks - Pawan

SNP - Issue with PDS as source of supply in low-level code run

Hi All:
I have a bunch of PDS that is giving me the following message when the SNP Low-level code is run:
''Invalid source 00000010382991380SLT1 S is not considered for low-level code calculation. The source of suppy 00000010382991380SLT1 S is available actively in the Supply Chain Model. The location product for which the source of supply is intended, does not exist, however, or is no longer assigned to the model. The source of supply is therefore invalid. ''
I tried all of the following but still did not get to work
1. Made sure that FG and all the active component of one FG and the location and the PDS were in an active model.
2. Made sure that there was one production version and hence one PDS
3. Intialiazed the Planning area with the version
But still would not generate the low level code for the product location. Can some one throw share some insight and help pl?
Thanks
Ryan

Could you please check whether in the Product Master, Procurement tab, the Procurement Type is set as "P - external procurement planning"? If yes, then that's the reason as the Low-Level Code is only calculated for Products that are to be planned in APO. In this case, change procurement type to X or E and it should work.

Tiago

SNP Optimizer run ends with error: Error when determining Customizing data

Hi All
Can you help please what settings are missing: SNP optimizer run canceled with error "Error when determining Customizing data".
Thanks
Best Regards

On integration tab of SNP optimizer profile,
maintain 'regard as customer demand' for both dependent demands and distribution demands for fixed orders.
By default it is 'regard as hard constraint' which should be changed.

SNP Optimizer Issue

Hi Experts,
We are working on SNP Optimization scenario with Transportation, Procurement, Strorage and penalty Cost. Our business process trading industry (we procure and sell).
We maintained Optmizaion profile with linear and Primal simplex Algorithm. We took a sample scenario where our product has four suppliers with diffrent transportation costs maintained in transportation lanes.
In SDP94, Optimizer behaving diffrently.
Case 1: When we run directly at destination location (product + Destination) level optimization running smoothly with out picking any transportation lanes, costs. Subsequently no purchase requistions are created.
Case 2: When we select all locations (Product + Source and Destination) and run optimization the following errors are coming which we are not able to identify the origin.
Error 1: Cost function 051MhWG07j6MwgLZXQcXSm not found
Error 2: Conversion from STD to EA for product WDE-MATL1A not maintained
Error 3: Error occurred when reading data
We checked CCR no errors are identified. Also there is no UOM called STD. We couldn't understand why Optimizer is proposing STD to EA conversion error.
Can you please throw some light.
Thanks in advance

Hi Ugameswara Rao
When you run optimizer,you need to run as a whole including all teh Network...So,the first observation is standard
Regarding teh second issue,It is a Master data inconsistency,So,please identify the 'concerned location product' and maintain the cost accordingly(Check teh log to find the concerned location product)
Regarding error "Error occurred when reading data",please raise a seperate thread,as the raesons for this are multiple...but try this first run //om17,model consistency check and correct the data model set...but,the reason for this could also be a softwre error....hence,if the above don't help,please rasise a seperate thread with all details like: STEP in which thi serror occur,and also teh message log details
Thanks and Regards

Creating non pegging relevant snp orders by using snp optimizer

Hi all,
We want to create snp planned orders with non pegging relevant by using snp optimizer, how can we do this?
Regards,
Burak

Hi Burak,
In IMG, use the following menu path
SAP SCM Impl Guide --- APO --- Supply Chain planning --- PPDS --- Global settings --- Maintain Global parameters and values --- Under Planning Tab --- Activate fixed pegging.
This is universal setting for the entire client.
Hope this helps.
Please confirm

How do you run the optimizer with fixed orders?

Hi experts,
If the planner wishes to prioritize orders based on the customer demand, orders should be set as fixed.
How do I run the optimizer when using fixed orders??
Regards,
Analía Nahmías

Hi Analia,
Will you please elaborate more ?
It looks you are running SNP optimizer and want to use also make use of order prioirty functionlity.
You may be knowing already the contents below :
We know that Demand Prioritization functionlity is handled differently in SNP CTM and in SNP Optimizer.
In SNP CTM, Demand can be sorted by different sort criteria.
Whereas in SNP-Optimizer, Demand can be aggregated for three demand classes or by customer locations.
We set prioirties on the SNP Optimizer profile Maintenance for demand classes ,
1. Sales orders
2. The Corrected demand forecast
3.The demand forecast
Apart from this, we can set flag for priority of location products
The optimizer considers the priority of location products in combination with the priority of priority classes of the demand. To simplify this combination, we must group the priorities of the location products into three classes.
Within every priority class as above, the APO system uses all available cost information to determine the final solution
With the above way, planner does not have to fix an order.

Datta

Considering Forecast in the past for SNP optimizer

Does SNP optimizer considers the forecast in the past as a requirement?
I tried with standard book and dataview but SNP optimizer did not consider past forecast. I checked optimizer log, forecast was not there also.
Am I missing something? Or is it default behaviour?
Thanks.

Hi
Yes that is the default behaviour, essentially the Optimiser has assumed that anything in the past has already occurred and will only start to plan demand from the first bucket onwards.

Ian

SNP Optimizer dropping the demand

Hi,
While planning using SNP Optimizer against a given demand in a constraint scenario, the optimizer is dropping significant demand.
Capacity of the production factory is not constraint. But somehow a lot of demand is not propagated to the factory. In fact, out of the 3 factories where one product can be produced, one factory did not get any plan at all !!!
Can you please help me understand the other possible reasons why this can happen? The master data - Lanes and production master data at the factory is maintained correctly.
Regards,
Ankur

For a demand to be considered in the optimizer Run following are the checks to be done:
1. Lane should be defined from a location where the demand is to a valid source. (lane can be at location level for all product or lane can be product specific)
2. Cost definitions: If the production + transportation cost for the product at source is greater than the Demand loss cost at dest loc there wil be a demand loss. Please update the Demand Loss cost in /SAPAPO/MAT1:- SNP1 tab. Total demand loss cost after planning is avaialble in IT_NONDELV table in Optimizer Log
3. Capacity avaialble for planning. resources to be properly defined and capacity availability to be checked (IT_RESOURCE) will give the details wether the reource is avaialble
4. If a PPM is used with output componenet demand uinmet we need to check whether the input product is produced (capacity to be checked for input Product production to happen)
these are few basic checks for Demand Unmet

SNP Optimizer - unfullfil demand

Hi
I run snp optimizer for 1 product A, it work out fine . subsequently i run the same optimizer for the a range of products .. . it overwrite the result and cause unfulfill demand for product A.
Any particular area i need to look out ? i cannot just keep running optimizer for that single product to fulfill the demand .
remark
all the product is imported finish goods

Hi,
the possible check you need to carry out to get the reason of the unfulfilled demand.
1. Check the resource consumption used by that particular product. Possibly the resource might have been consumed by some other products.
2, Check the Planned orders generated for
2. Check the cost in the PPM , Tlane, and Product master. Compare with the products which are using the Location resources used by A.
3. CHeck the Penalty costs maintianed to check why the priorities are given to other products.
for the all the above you see in /SAPAPO/SNPOPLOG
Hope this helps.

SNP Optimizer and dummy procurement

Hi,
Is there anyway SNP optimizer don't create dummy purchase orders at the distribution center? We have high penalty cost for non delivery. If there is no supply available/ (or some reason master data is missing), Optimizer is creating Purchase requisition without any source of Supply. We want to avoid this Purchase requisition.
Thanks everyone for sharing your expertise.
Shibu

Hi,
Optimiser will not create Pur Req with source as blank if the supply is not avaialble at the source, instead it will incur demand loss cost.
Opt will create PR with source blank only if you have define Procurement type as F and no source has been defined, you can either define a source or change the procurement type to E.
Also their is a note in case of optimiser which prevents creation of PR with source as blank, but I am not able to access the SAP notes and so cant provide you with the note number, you can just check out.
Thanks,
Sanjog

SNP Optimizer and product priority

Hi all,
Is SNP Optimizer respects product priority? Some part of the documentation says, it respects, and someother part says no consideration. Which is correct ?
Shibu

Hi Shibu,
The product priority is not considered by the Optimizer -
There are actually two ways of giving the priority -
1. It is by giving different Non Delivery and Delay Penalty Cost for these products.
2. The other option is SNP Optimizer Priority Profile which is less complicated in terms of Master Data Maintenance. If you define the priority profile then the optimizer first plans the products with more priority and then plan the other set of products.

Differece between SNP Optimizer and Deployment Optimizer

Hi,
Can anyone please list down the difference in the planning method for a deployment optimizer and SNP Optimizer?
Thanks & Regards,
Sanjog Mishrikotkar

Hi Sanjog,
First of all if we understand the difference between SNP Heuristic Planning run which finds the 'Source' of Supply with dates and quantities and Deployment Planning run which CONFIRMs the Supply .... then it is easy to understand the difference between SNP & Deployment Optimizer.
The Optimizer as you know Optimizes based on Costs and Objectively tries to MINIMIZE it. Therefore while the SNP Optimizer finds the most cost effective way of finding the Source of Supply with dates and quantities, identifying where in SC it is better to Store or move the Product, while the Deployment Optimizer generates the Best way to CONFIRM whether the Supply can ACTUALLY be done for the next few days. Deployment precedes the TLB Run which after confirmation we put the Quantities on a Transport Load to build Orders for Execution (Shipping).
Both are Cost based & use the Same Costs Information ... however one Plans and the Other Confirms. During Deployment Optimization run, the Optimizer may decide to confirm the supply from a different source than what the SNP Optimizer planned based on the Available to Deploy Stock Quanties and the Cost of Confirming the Supply. The Deployment Optimizer will apply Fairshare & Push/Pull Rules and looks at the Push and Pull Deployment Horizons which SNP Optimizer cannot. The Difference is also in Planning Time Range. You plan SNP Supply for mid to long term time range. The Deployment looks at Confirming the supply in the next few days from TODAY.
So in short first understand the Difference between a SNP Heuristic and Deployment Heuristic and apply the same principle to a cost based optimization. This should tell you the difference between the two.
Try read this ... First para on Deployment Optimizer ...

Hope you find this answer usefull. Reward Points if it is.

Penalty Cost Groups in SNP Optimization

Hello APO experts!!
I would like to know if any of you have more information about the of penalty cost group in SNP Optimization.
I have been researching on the help.sap.com web site but I need more details.
Can anybody help me?
Best Regards
Angela

Hi Angela,
1) You can use penalty cost group for optimization-based planning in Supply Network Planning (SNP) to define that customer demand is prioritized.
2) You can use the Business Add-In (BAdI) /SAPAPO/SDP_RELDATA to assign penalty cost groups to forecasts and sales orders
3) You then release the forecasts with descriptive characteristics, such as customer, to SNP or transfer sales orders from SAP ERP to SAP SCM via the Core Interface (CIF).
4) In SNP 1 tab page for product master data, you can assign penalty costs for non-delivery and delays to the penalty cost groups. In this way, penalty costs become customer-dependent.
5) You can use the penalty cost group to define that the system first covers the demand from penalty cost groups with a higher priority, and only then covers penalty cost groups with a lower priority.
6) Penalty cost groups are controlled by penalty cost group profiles
7) You define the profiles from the SAP Easy Access menu, by choosing Advanced Planning and Optimization -> Supply Network Planning -> Environment -> Current Settings -> Profiles -> Define SNP Penalty Cost Group Profiles and then assign them to individual optimization runs in interactive planning or when executing the SNP optimizer in the background.

R. Senthil Mareeswaran.
