Fixed pegging with SNP heuristic

Hello Guys,
I have a requirement from the client and to achieve this i wanted SNP heuristic to consider fixed pegging created manually.
So i have the below doubts:
1. Do SNP Heuristic consider the manual fixed pegging. I tested the scenario but its not working.
2. Is there a work around to it.
Thanks
Kishor

Hi Cyrille,
Thanks for quick response.
Let me explain the scenario,
                   wk1     wk2
Forecast      10
Receipt        10
The above situation after SNP planning run.
                   wk1      wk2
Forecast      10
Receipt                    10
2nd table is after pushing the receipt to wk2 manually.Now when i ran SNP heuristic, its creating another receipt on wk1 of 10, which is a situation of excess supply.
I do not want heuristic to create another receipt for wk1. Manual fixing can help, if heuristic will consider it.
Please help.
Thanks
Kishor

STR pegging with Sales Order

Hello Experts,
I have a scenario in which STR (Stock transport requisition) is FIXED pegged with Forecast and Sales Order.The requirement is, I want to fulfill sales order only with this STR not the forecast.
I am able to change the STR quantity with the pegged quantity with sales order using BAPI ( ie: STR Qty = Pegged Qty of SO) But when I see the pegging overview, in product view (/SAPAPO/RRP3),System is fulfilling forecast first and then sales order.
I tried to change the STR quantity manually in product view,but still it is pegged with forecast first which I dont want.
I want STR to be pegged only with Sales order not with any other order.
Do this require any setting somewhere in SPRO? or this is a normal case in SAP APO? or Do I need to break pegging relationship first then create new pegging relationship with SO only?
Please advice.
Regards,
Saurabh

I think we can not break pegging and create new one with desired order.I am not using any SNP engine...
I have tried to change the STR qty but it is automatically respecting forecast first which i dont want to do....I changed order dates,Pegging Strategy in product master also but it is not happening......
I am talking about normal product view in which STR is fixed pegged with the SO and forecast,I want to change STR qty in such a manner that it should fulfill only pegged sales order not any other order.
Please advise me how to achieve this without any planning run?

Use of manual sequencing heuristic with consideration of Fixed pegging.

Hi,
I have scheduled the FG and SFG order through optimization for 3 days.To correct the sequence i am using manual sequencing heuristic i.e. SAP003. in the setting i am taking option consider fixed pegging always,scheduling mode as insert operation and scheduling submode as schedule dependent operation according to scheduling mode....But problem i am facing after running this heuristic as some FG orders are getting scheduled before SFG orders and one more problem is orders are crossing the scheduling horizon i.e. 3 days horizon......
Kindly give some input to resolve the issue.

SAP_pp_019 heuristics creates automatic fixed pegging relation ship .generally we have automatic fixed pegging and manual fixed pegging

SAP_pp_019 heuristics creates automatic fixed pegging relation ship .generally we have automatic fixed pegging and manual fixed pegging .
Example :
1) created sale order and triggered GATP
2)It calls CTP where SAP_PP_019 is run and coresponding planning takes place and pegging relation ship are generated in product view
3)when I Trigger Gatp to same sales order .why the pegging losses as it is fixed pegging so it should not break while converting to production order ?????
please correct if am wrong in any of 3 steps
Thanks & Regards
Virender

Virender,
Expert Pravin has answered your question about Planning Procedures
I will make two small comments. In my CTP experience, I have never seen anyone use the SAP_PP_019 heuristic as a CTP heuristic. 019 is a pegging heuristic, and typically CTP uses some type of material planning heuristic (e.g. create supply elements). I am not saying that your heuristic is wrong, I am only saying that I have never seen it used in such a way.
I have further never seen an implementation for CTP where there were more than 2 different planning procedures in use.
You did not ask for it, but let me give you a small piece of advice. CTP and multilevel planning are not simple or trivial subjects. From your responses about planning procedures, I will draw the conclusion that your experience in this area is...somewhat limited.
Yes, you can go to SCN and ask for advice, and we will offer whatever help we can. However, the detailed troubleshooting techniques required to solve such a problem are not really suited to SCN postings. There are already 30 items in this post, and the end does not seem to be in sight.
If I were in the position of being responsible for solving this problem, and I had little experience to bring to bear, and there was no documentation which described the original solution in detail, then I would request local expert assistance to help me in this matter. If such assistance were not to be available, I would further request my management to engage an external resource to assist; one who has extensive experience in customized CTP solutions. A competent CTP expert can probably zero in on the problem in a few days.
Using only yourself and SCN as a resource, you may find a solution to your problem tomorrow, or you may not find it after months of searching. In most businesses I have worked with, this level of uncertainty would be considered unacceptable.
Good Luck & Best 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

Late Demand Fulfillment with SNP Heuristics

Hello all,
It is well known that SNP Heuristics does a bucket level planning and demands in each bucket are treated independent of the future bucket demands while creating the receipt elements. The receipts are created within the bucket unless there are sufficient receipts available in the past buckets that can be used.
Now, my question is, if we can force Heuristics to have the receipts in future buckets consumed with current bucket demand and not have to create additional receipts within the current bucket during planning run.
In a nut shell, can we influence heuristics not to plan receipts if there are fixed receipts available in future buckets?
Please note that settings like fixed pegging, maximum lateness of receipt, and late demand fulfillment do not work for heuristics. I have tested extensively using all of these settings.
Is there a way we can influence it to look into the future and if there are receipts available in any future bucket, say 30 days or 4 buckets ahead, in a weekly planning situation, it should not plan receipts in the current bucket and consume the receipts of future.
If any one has done such a thing earlier and can provide pointers, that will be grateful.
One option that came through discussions is changing standard macros to influence the way receipts are seen by heuristics during bucketed planning. Has someone explored this option? Please revert.
Thanks and warm regards,
Chandra

Hi Dieter,
Please check if the plan order is tied to your SO (t.code /SAPAPO/CTMVIEWER or in the /SAPAPO/RRP3). Also check in CTM profile (tab Supplies) what is your settings in the supply control section (Build Up Safety Stock and Stock is available). They should be active.
In the Planning Strategy tab what is the scheduling direction and pegging type?
Also check the Planning Strategy (planning mode & delete mode).
Thanks, Marius

Pegging between SNP orders?

Is there pegging relationships between SNP orders? If it's so, what are the differences between pegging of SNP and PP/DS orders.
Thanks

Hi Mikalai,
SNP has 3 solvers for rough-cut capacity planning i.e. Heuristics, Capability-To-Match and Optimizer. Heuristics and Optimizer are time-series based solvers and pegging is not supported using these solvers. The only solver that is order-based is CTM and with CTM pegging is possible. Even though CTM is different from rest of the SNP, it is often gets clubbed with SNP functionality.
SNP can only schedule to a minimum of one day granularity and where as PP/DS can schedule to second. As far as pegging methods are concerned, fixed & dynamic pegging are available for both CTM & PP/DS.
Hope this helps.

Fixing entry already exists . Error in creation of fixed pegging

Hi,
we are calling CTP from GATP after product availability check. Using fixed pegging relationship through standarad abap class
error message is coming as
Error occurred during creation of fixed pegging relationships

Dear Santosh,
the common cause for the error LC Return code 17313:
The heuristic tries to determine locking arguments, but other processes are locking these.
Therefore the proposal,
1. Don't run the MRP in a parallel mode.
2. Check the note 513827 for more information.

SNP Heuristic: Creation of purchase requisition

Hi experts,
we face following problem: heuristic creates purchase orders when there is no source of supply.
Background:
there is a forecast demand for a location product on a customer location without transport lane to the production plant due to false master data.
The SNP heuristic generates purchase requisitions to fulfill the demand and there is no requirements shortage.
So it is hard to recognize which forecast demands can't be fulfilled.
Is there a parameter in material master or in a heuristic profie which disables the creation of purchase requisitions in snp heuristic when there is no source of supply.
If no purchase requisition is created there will be a requirement shortage which can be recognised by an alert.
Thanks for your help.
Robert

hi.
As per heuristic process , the system will create a purchase requisition if there are no Tlane exists and the material's procurement type is F/X since it is a infinite planning.
Now you can use a optimizer or CTM to restrict the system from creating purchase requisition.
Also you can try with location heuristic.
Hope this can help.

kaushik

Planned Delivery Time in SNP Heuristic

Folks
Need help in mapping the following requirement. We are implementing SNP heuristic, the requirement here is..
1) When Heuristic plans a product, it should ignore the lead time when ever the demand is with in the lead time and should create supply in the past and respect the lead time out side of the lead time.
E.g:
Today - 25th June
Procurement Lead time - 10 Days.
Available stock = 0
Planned receipts = 0
Demand on 28th June = 100
We want heuristic to create receipts for the demand with opening date in the past & delivery date to be 28th June.
Kindly help if you think we can make SNP heuristic meet the above requirement.

Hi,
I am new to APO.
This kind of situation can be handled in R3 by allowing the Orders to be created in the Past by setting
the ' Start date in Past allowed indicator ' while defining the Plant Parameters for the Plant in MRP and while mainaining the MRP Group also.
Thanks,

Long running SNP heuristic in the background

Dear Experts,
In SCM 5.0, randomly we encounted an issue where running SNP heuristic takes a long time to run and never completed...usually, this will takes less than couple hours to complete.
I checked with Basis and they confirmed the sytem operates normally. Can you advise what would caused the long running issue and how I can prevent it.
Thanks,
Tom

Dear Tom,
1. It will be useful to run Low level code determination procedure before running the SNP heuristcis to improve the performance.
2. Secondly, I hope you are using parallel processing profiles functionlity. This will certainly help .
3. We used seperate jobs location specific for SNP heuristics and ran some jobs in parallel with some offset / delayed start
4. Running SNP heuristics only for the active products always helps, rather than running SNP heuristics for all products ( actvie products , obsoloete codes, ). One of the way may be to have seperate SNP planner codes to seperate out obsolete codes
I hope these steps may help.

Max stock level as safety stock from material master while running SNP Heuristic

Hi Experts,
Our user wants to consider max stock level as safety stock from material master while running SNP Heuristic, not the actual safety stock.
Is there any possibility for this setup?
--Kishore

Hi Kishore,
With the given details I suggest that the user can maintain the max stock level values directly in safety stock field of the material master for all materials to be planned by SNP heuristic (keeping the max stock level field blank). Then this safety stock field (which has actually the max stock level values) will update the safety stock values in APO product master and in turn can be considered for SNP heuristic.
Note: The max stock level field in APO product master is used by SNP heuristic only when the target stock level method is maintained as 4, 5 or 6. Since your requirement is to use max stock level as safety stock, so it does not look like that you will be using these target stock level methods or the max stock level field in R/3 and APO. So, this can be left as blank in both R/3 and APO.
Please let me know if this helps.

Period factor VS SNP heuristic & deployment heuristic

Hi ,
I am using period factor to decide avalabilty date with in each bucket. i know first periority would be period factor in Tlane . accordingly i maintained period factor 0 .
SNP heuristics cretaes the receipts in the start of the buckets since period factor is ZERO.
But when i execute Deployment heuristic its NOT cretating in the start of the bucket. instead its creating middle of the each bucket
My questuion is.....
1) period factor setting is only for SNP Heuristic NOT for deployment heuristic???
2) if thats the case how to decide manually creation date in deployment?
3) Receipts available in middle of the bucket , But depoyment confirms the demand in the START of the bucket ? logically how its possible. it should not be???
Regards
Rajesh

Hi,
My understanding is that period factor of 0 is interpreted as 0.5 by heuristics.
So in your case Heuristics should create stock transfers in the middle of the bucket and deployment should just confirm it.
Please let me know the following.
You have maintained factor 0.5 in lane right?
Have you maintained any value in the product master?
What is your deployment method, pull or some type of Push?
What is your bucket type (days/weeks/months)?
Hi Claire,
I do not understand why a simple pull deployment has to schedule the stock transfers again?
It should just check the ATD qty and confirm the heuristic order, if possible right?
Could you please explain your point further with a scenario?.
Regards,
Ashok

Quota arrangement in SNP heuristic

Dear all,
we want to use inbound quota arrangement in snp heuristic to distribute the demand among different ppm. But it seems that the snp heuristic don't respect periodic lot sizes in case of quota arrangement. In product master we have defined 2 weeks periodic lotsize. But the heuristic applies muliple planned oders for the same day. Any ideas?
Christian

Hi Christian,
I checked in sap help files also and found that SNP heuristic does not support periodic lot sizes in terms of quota arrangements. I have given below the lot size supported by sap from sap help as follows:-
Lot size
· Procedure (lot-for-lot, fixed lot size etc.)
· Safety stock method

Fix Pegging MTO

Dear all,
i have one question for fix pegging and MTO scenario. I have a MTO order and already a customer stock for this order.
Now i run the heuristic SAP_PP_019 for the fix pegging, everything is fine. After this i run a product heuristic and now the
system creats a additional planned order. Why?
I know that in a MTO enviroment a fix pegging make does't make much sense, but if someone can help me to understand why the system reacts like this.
We run a SCM 5.0 system
kind regads
Bernhard

Hi Bernhard,
Which product heuristic are you using?
Please check the settings for your product heuristics, in particular for netting off of receipts. I checked for MTO for fixed pegging and then for MRP heuristic, but dint create second planned order.
Also, are you transferring your planned orders to ECC? I had experienced this problem, that when I transferred planned orders to ECC, and then re-run MRP heuristics in PPDS, second planned order was created.
Please provide details of your heuristics and what kind of material are you using.
Regards,
Bipin
