SNP and PPDs horizons

Hi,
If I have SNP horizon of 0 days and PPDs horizon of 0 days. Then does the system plan twice and I see double the quantities because both SNP and PPDS are planning the same time? I mean does it create both SNP and PPDS planned orders doubling the planned qty.?
Thanks.

Typically if both these horizons are zero in the Location Product, the system is supposed to check the PPDS horizon kept in /n/sapapo/mvm transaction. Usually its a best practice to have a non-zero value in the version level. under the situation where even PPDS horizon at version level is 0, I would expect PPDS orders not be created at all by any systemic process. (different PPDS heuristics work differently though) However it should be possible to create PPDS orders manually outside of the PPDS horizon. Usually SNP orders are deleted and PPDS orders created in its place by the PPDS solver as soon as those orders are inside the PPDS horizon. I would be surprised by what you are observing though.

SNP and PPDS Horizon

Hi All,
Can anyone please let mw know what exactly is the difference between SNP and PPDS Horizon ??
How is it identified. .
What are the applications of using these horizons . .
Thanks in Advance,
Prasad.

SNP Horizon: Time segment, during which SAP APO Supply Network Planning (SNP) does not plan production. This means that SNP does not create any planned orders in it but shifts production to the first day after the end of the production horizon.
PPDS Horizon: Time segment in which Production Planning and Detailed Scheduling (PP/DS) can automatically create, change, or delete receipts. The duration of the horizon begins on the current date and continues for this number of calendar days into the future.

Difference between SNP and PPDS.

Hi all,
i want to know the functional diff betwn Snp and PPDS. .
i mean what activities come under Snp, after what activities it is under PPDS. . .
Any info on the same will be highly appreciated.
Regards,
Prasad.

Hi Prasad,
SNP basically does rough cut capacity planning on a constrained or unconstraint situation whereas PPDS does time continous finite capacity based on constraint or unconstaint situation.
SNP & PPDS works on horizons. There are scenarios were SNP horizon can overlap with PPDS horizon.
SNP uses SNP PPM as master data whereas PPDS PPM as master data. The output are SNP orders and PPDS orders.
The minimum day for SNP planning is 1 day whereas PPDS can go upto even 1 sec(ie microscopic planning)
Starting from a demand plan, Supply Network Planning determines a permissible short- to medium-term plan for fulfilling the estimated sales volumes. This plan covers both the quantities that must be transported between two locations (for example, distribution center to customer or production plant to distribution center), and the quantities to be produced and procured. When making a recommendation, Supply Network Planning compares all logistical activities to the available capacity
We use the Production Planning and Detailed Scheduling (PP/DS) component
a) To create procurement proposals for in-house production or external procurement to cover product requirements
b) To optimize and plan the resource schedule and the order dates/times in detail

CIF PDS for SNP and PPDS

Dear Experts,
I am using SNP and PPDS
do i need to have sales bom for SNP PDS is it mandatory ,
or just normal production bom is enough for having both snp and ppds Product data structure
Thanks & Regards
Raj

Dear Satya,
Thanks for your reply
I know PV is needed for SNP PDS , is the PV which is used for SNP PDS is same for PDS PP/DS, or we need to use and special key during CIF ing to APO from ECC 6

Fetch SNP and PPDS orders

hi,
I am new to APO. How to get PPDS and SNP planned orders from livecache.
Regards
Dhanu

1)     I am able to get all SNP and PPDS order using BAPI called BAPI_PPDSSRVAPS_GET_IO_NODES from Live cache. This BAPI fetching order id as key field.
2)     I need to fetch the data from DMCP table using this order id but there is no link with this order id with DMCP table.
3)     There is a field called GUID in DMCP table. I used one FM to convert order ids to GUIDs to get the data from DMCP table. All order ids got converted into GUID.
4)     Till here everything is good.
5)     But when I am trying to pull the data from DMCP table based on GUID, it is pulling only SNP orders not PP/DS orders.
6)     I have tried so many ways but I am getting SNP orders only.
7) I need SNP and PPDS orders
Can you help me on this?

SNP and PPDS planning horizons

Hai,
        I am reading through SNP and PP/DS planning horizons. I understand that SNP doesnot plan anything within SNP production horizon whereas PP/DS plans only within the PP/DS horizon.
Now, I get confused when trying to understand the following sentences:
1. If production horizon of SNP is smaller than the PP/DS horizon, the planning horizons of SNP and PP/DS overlap with each other. In this horizon, SNP determines the receipts with most cost-effective sources of supply and lot sizes and PP/DS plans the receipts in more detail.
2. If requirements within the SNP production horizon cannot be covered by PP/DS, then SNP plans the receipt outside the SNP production horizon(this corresponds to the logic in the PP/DS planning time fence in short term planning).
3. If the PP/DS horizon in the product master is set to be greater than SNP production horizon, this gives rise to an overlapping area in both SNP and PP/DS receipts are created.
Can anyone please help me undestand the above? An example or somedocumentation reference is appreciated.
Thank you.

Hi Visu,
Good question. You missed Planning Time Fence in the equation.
|--||--
>
1.       PTF             SNP            PPDS
You execute PPDS Heuristic (Product Heuristic) then requirements upto PPDS horizon will be covered by receipt elements (beyond Planning Time Fence). If you run SNP Heuristic then receipt elements will be created from SNP Horizon out in future deleting the receipt elements created by the previous PPDS run. But note that while PPDS planning is down to the second level SNP planning is minimum at a day level. If you have weekly buckets then all requirements for one week will be clubbed and single receipt element will get created. However you can consider SNP orders as fixed during PPDS Net Requirement Calculation through appropriate development.
|--||--
>
       PTF              PPDS           SNP
2. This is also not clear to me as I cannot build the scenario as described. The above diagram is the closest I could come up with. But in this case if you run SNP Heuristic and there are unmet requirements (sitting between PPDS and SNP horizon) then the receipt for that will be created only at the start of the SNP Horizon.
3. This is correct but already explained in 1.
Hope this clarifies or at least does not add to the confusion. BTW if you are interested then please read OSS Note 481906 - SNP - PP/DS integration (documentation).

Min max lot size time based for use with SNP and PPDS

Hi all, Is there anyway to set up time based min and max lot sizes? ie we want to have a Max lot size which is small for use with the first 3 months of our plan which starts life in SNP and then converts to PPDS and into blocks for block planning, but months 4 to 36 we want to leave as large max lot sizes as there is no need to have the small max lot sizes for the different horizon.
As far as I can see there is only a material/plant lot size and Max lot size and no way to have a different setting in a different time period.
Thanks
j

Hi John,
As you know, in the product master, the lot size maintenance is time-independent, so that obviously can not be used for your scenario. As per my understanding, to meet this using standard functionality, you can maintain multiple product specific t-lanes (for STRs) and PDSs (planned orders) with required lot size ranges and validity dates (for short or long term horizon). But, again since the validity of t-lanes and PDSs will not be automatically rolling forward so the updating the validities will be a challenge.
The other option could be to enhance the heuristic functionality at lot size selection step while creating order.

Umesh

Key Differnence between CTM in SNP and PPDS

Dear Experts,
Can any one tell me what are the key difference between SNP CTM and PPDS CTM
Thanks & Regards
Raj

Hi Raj,
You can use CTM both for master data of type PP/DS, and
for master data of type SNP.
Because CTM planning works on an order basis, you can
determine and trace the relevant receipts and supplies for each
demand in the entire supply chain, after the CTM planning run.
PPDS in general will be used for short term planning wherein
CTM can be on mid to long term planning.
Both belongs to SDM category of SCM which uses order series.
In terms of master data, the plan explosion will decide on usage of
plan for PPDS. For resources, you can use time continuouse for
PPDS relevant and bucket for SNP oriented

Master data related fields for DP, SNP and PPDS needed in Material Master

Hi Gurus,
Can any one please suggest or guide me what are the fields need to be done in Material master in ECC for SAP APO DP, SNP (heuristic with capacity leveling)& PPDS(Heuritic with optimizer).
Please it will be really great help.
Thanks in advance
Regards,
Kumar

Hi Kumar,
For DP, many of the fields under MRP3, forecasting tab
views will be utilised more in material master of R/3.
For SNP, MRP 1, 2,4 and basic data views will be mostly
useful
For PPDS, Fields under Bom, routing, receipe, production
versions will be used along with few fields in material
master

Rolling schedules for steel options between SNP and PPDS

We are trying to set up something within the APO SNP/PPDS tool to
plan rolling schedules for steel.
eg multiple resources, most of which are 100 percent rolling schedules,
with many different "blocks", and common rolls may occur say every 4 weeks, or
every 14 weeks.
And so each roll we need to plan "Quantity required before the next roll" - eg
a 14 week quantity.
We have set up PPDS Blocks using CDP settings with characteristics in our
test system.
Seperate to that we have an SNP model where we plan across multiple plants,
for a 12-24 month period, and we have multiple level BOMS where there may
be 2 semi-finished products between the Finished and Raw material. Eg heat
treated and non-heat treated.
Sometimes one of the interim semi-finished products is the bottleneck, so we
need to use capacity leveling to reduce quantities at all levels of the BOM.
Our main issue is that the SNP quantities that we plan, we are not able to feed into
the PPDS blocks, as SNP does not deal with characteristics.
So in our test, all we can do is use the SNP quantities for higher level plans.
Then delete the SNP orders, and re-run a new PPDS plan to get quantities in our blocks,
but we then have lost all the capacity levelling information from SNP.
Does anyone have any method to deal with this scenario? ie how to model rolling schedules
by utilising the strengths of the SNP mult-plant and capacity leveling data, and then
somehow also taking into account "blocks", or "rolling schedules"?

In our testing. With CDP setting, we create a fcst element with a characteristic on the material. eg RED/BLUE/GREEN, and in PPDS, I can then create a PPDS order with the characterstic linked and visible in the PPDS order, and linked to the BLOCK on the resource (Blocks of RED GREEN for example)
But SNP orders do not work with these characteristics.
This is backed up by various documentation from SAP.
eg
http://help.sap.com/saphelp_scm50/helpdata/en/b0/3c2463c7cbb54bacfb75c789100ad4/content.htm
SNP cannot plan with characteristics. However, the characteristic assignments remain and can be evaluated in PP/DS.
CDP in SNP
CDP cannot be used in SNP as the SNP does __not support__ characteristics.

(In this book - a list of which APO areas do and do not work with Characteristics. SNP does not)

Does Make To Order planning consider any SNP/PPDS Horizons

Guys
Does Make To Order planning consider any SNP/PPDS Horizons unike the Make to Stock scenario planning?
Thanks

Thanks for the response guys.
In RRP3 view, when I look at the Individual project segment demand, I do not see any SNP/PPDS Horizons. However, when I see the demands under the MTS segment, I can see the SNP/PPDS Horizons.
In MTS scenario, I understand that only those orders that falls within PPDS horizon are picked up by PPDS planning and orders outisde SNP horizon are picked up by SNP planning.
However, as MTO is purely PPDS planning, I am just wondering whether SNP or PPDS horizon comes into the picture in this scenario or not.
Further more, my primary concern in MTO scenario is, if PPDS horizon is taken into the picture ( which is usually in the near visible term and < SNP horizon, say 15 days), and as PPDS planning doesn't pick the demand in the MTO segment until the demand falls with in this horizon, aren't we not leveraging the full functionality of procurement planning, as PPDS plans the demand by picking it just before 15 days (in this example) of the original requirement date, and the company might not be able to fulfil the customer order as the replenishment time might be long for this particular product being procured/produced.
So, I am basically leaning towards an understanding that what ever demand that falls in the Individual Customer/Project segment (MTO), it will be picked up PPDS planning regard less of SNP/PPDS horizons.
Please advice, if my understanding is wrong and I would appreciate if you quote some examples which might help me better understand the scenario.
Thanks

Planning horizons of SNP and PP/DS

In didn't understand the below terminolgy , can anyone please explain the meaning of it in detail..
The planning horizons of SNP andPP/DS overlap , if the SNP production horizon is shorter than the PP/DS horizon

Please see the following two forum threads

APO SNP optimzer & PPDS optimizer

Dear Experts,
When i am doing my capacity leving using optimzer method in SNP
system propose optmizer server is not installed in SNP
its seems no optimzer server for SNP and PPDS was not installed , i try to run test connection to optimzer server
it fails
Just wonder as functional consultant what need to tell to the basis team
can any one guide me on this technical stuff
Thanks & Regards
Raj

Hi Raj Kumar,
1) Once you show them the error, they fully understand
what is the action to be done for that error
2) You can also tell them to check the RFC connections
3) Tell them to check the Optimiser installation is proper or not like
4) Ask them to use transactions /sapapo/opt12, opt03 if required
This will suffice.

PPDS Horizons and PPM

Hi Gurus,
              Can any one explain me the difference between
1. Opening periods
2. PPDS plng Time fence
3. Adjustment Horizon
4. Rqmts Ascertain Horizon
5. PPDS Horizon
& also please explain me step by step how i can create PPM for my finished products
Please let me know.
Thanks & REGARDS
Kumar

Hi Kumar,
Continued...
3. Adjustment Horizon and 4. Rqmts Ascertain Horizon
These two horizons are relevant to sales order oriented planning. In sales order oriented planning we only convert procurement proposals (planned orders and purchase requisitions) into manufacturing orders or purchase orders if theses procurement proposals are used to cover sales orders.
Adjustment Horizon : Using specific PPDS heuristics, we delete planned independent requirements for which there are no sales orders, and adjust the purchase requisitions and planned orders used to cover these planned independent requirements accordingly.
u2022     To adjust the planned independent requirements and procurement proposals for selected products, we use the standard heuristic SAP_PP_015. This heuristic executes the adjustment for all procurement proposals that start in the adjustment period. You can define the adjustment period using the adjustment horizon.
u2022     Using the standard heuristic SAP_PP_016 you execute the adjustment for selected orders. The adjustment horizon and the adjustment period are not relevant here.
Rqmts Ascertain Horizon: Using a specific PPDS heuristic (standard heuristic SAP_PP_014) we can determine the planned independent requirements for which there are no sales orders.
We can determine these planned independent requirements for procurement proposals that start in the requirements ascertainment period. We can define the requirements ascertainment period using the requirements ascertainment horizon. We can use the results to ask your customers to issue sales orders.
5. PPDS Horizon
This the time horizon in which PP/DS can automatically create, change, or delete receipts. Outside of the PP/DS horizon, receipts can only be planned manually in PP/DS
PPM creation:
In APO we have PPDS and SNP PPMs.
Please refer to the URL below which gives in detail the procedure for PPM creation:
