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

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.

Difference between SNP and DP versions

Hi Experts,
I saw in SNP we are using only version "000" where as in DP we use multiple versions. Is there any specific reason behind this.
Thanks for ur reply.
Regards,
Raj.

Hi Raj,
In SNP there is an active version and an active Model that you generate. The changes you make in that Active Model-Version combination are transferred to ECC system automatically. Where as other versions don't communicate with ECC. This is the concept of versions in SNP.
But in DP, the concept of versions is a lot different. Model has no meaning there and there is nothing called an active version even though you have version 000 there. Versions are used simply as means of simulation (trying various things and comparing the results) of planning results. Even though you use 000, the changes there are not updated in ECC system real time. Really the release to SNP or ECC just happens based on the version you specify during your release or transfer processes respectively.
Hope this answers your question. Please let me know if you need further clarification.

Difference between PPM and PDS, PPDS and SNP

Hello Gurus,
I'am a beginer to APO so could you please let me know about the difference between PPM and PDS? Also the difference between SNP and PPDS/
giri

Production Version in ECC can be transferred to APO as:
PPM - Product Process Model or,
PDS - Product Data Structure
These form the basis master data for Planning in APO
SNP - Supply Network Planning & PPDS - Production Planning and Detailed Scheduling are two Modules in APO for planning purpose.

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 PDS and PPDS PDS

HI Experts.
Can you tell the major differences between SNP PDS and PPDS PDS.
Thanks
Raja kiran R

Hi Raja,
Unlike PPDS planning (time-continuous planning), the least time bucket in SNP planning (bucket oriented planning) is a day, not seconds. Which is why the duration of individual activities in SNP PDS are planned in days only. Scheduling in SNP is based on the fixed duration of an activity and not based on order quantity or capacity load. If a plan contains 3 activities each with fixed duration of 1 day, then the SNP planned order will have duration of 3 days.
On the other hand in PPDS, the duration of an acitivity is calculated based on the resource load that generates the order quanitity, which means larger the qty to be produced, the longer the duration of the activity.
Hope this helps!

Difference between PDS and PPM and which one should be used for SNP /ppds?

Hi Gurus,
Just wanted to know what are the difference between PDS and PPM ?
1. For what industrial products we use PDS and PPM in SNP and PPDS?
2. which one can be refered to clients?
Please let me know it will be really great if anyone let me know the answers
Thanks & Regards,
Raj

Hi Rajkumar,
I have given below the detailed comparative account of PDS Vs PPM. Please copy and put it in an excel sheet in different columns and then read which is easy to understand.
PDS
1. Production Data Structure (PDS) in APO 3.1 & Run Time Object (RTO) in 4.0 and above versions
2. Master Data Object
3. Useful for scenarios where the compoenent has got different validity periods
4. Used as Master data Basis for Planning in SAP-APO
5. Contains active Master data from iPPE (Integrated Product and Process Engineering) generated from a production version
6. PPDS PDS & SNP PDS can be used as master data for planning
7. Change Management, variant configuration & Phantom assemplies are supported in PDS
8. Sub-contracting in SNP is fully integrated with R/3 is supported in PDS
9. Direct transfer of SNP PDS from R/3 is possible
10.Rapid Planning Matrix can be generated
11. Not possible to maintain PDS directly in APO and can be used only in combination with R/3
12. The transfer of data changes is simpler
13. Not possible to create alternate SNP-PDS in std system for different mode combinations
14. PDS can be automatically generated from two sources ie R/3 and iPPE
PPM:-
1. Production Process Model
2. Master Data Object
3. Cannot be used for scenarios where the component has got different validity period
4. Used as Master data Basis for Planning in SAP-APO
5. Contains active Master data generated from the combination of routing (BoM & receipe) and production versions
6. PPDS PPM & SNP PPM's can be used as master data for planning
7. Not supported by PPM
8. Not supported by PPM
9. Not possible here. SNP PPMs will be generated via PPDS PPMs
10. Not possible
11. PPMs can be directly created in APO and can be modified without R/3 also.
12. Little Complex when compared to PDS
13. Alternate SNP-PPMs can be easily created
14. PPM can be generated automatically generated only from R/3
PDS is used in industries wherein there are multiple components or assemblies having diffeent production versions whose validity periods are different. PPM is being used typically in process industries, chemical industries. PPM is very simple in its usage and very flexible in operations in terms of modifications at APO level and can be referred to client depending on the business requirement

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

Difference between snp planned order and pp/ds planned order

Hi to all,
can any one please explain the difference between snp planned order and pp/ds planned order. I am relatively new to this area

The primary differences are as below.
1. The master data for SNP Planned Order is SNP PPM/PDS where the minimum duration for an operation is a day. So it is used for rough cut capacity planning.
The master data for PPDS Planned Order is a PPDS PPM/PDS where operations are down to minute and second level. Moreover sequence dependent operation planning is possible in PPDS Planned Orders. It is for detailed capacity planning.
2. SNP Planned Orders are created in SNP while PPDS Planned Orders are created in PPDS or when transferred from ERP to APO.
3. SNP Planned Order need to be converted to a PPDS Planned Order before it can be used in the Execution System (ERP) for further processing - like conversion to Production Order. Moreover the category types of the orders are different in APO (EE for SNP and AI for PPDS).
Hope this helps.

Difference between C_TSCM44_65 and C_TSCM44_05 certificate

Hi,
Can you please let me know what is the main difference between C_TSCM44_65 and C_TSCM44_05 certificates. I understand one is for SCM 5.0(DP/SNP/PPDS) and another is for SCM 7.1(PP,SNP,PPDS,GATP) with the addition of GATP. Is there any other major difference.
In short ,if one were to do a certification, which one would you suggest.
Regards,
Shankar

Hello ShaikhMurad,
Actually, From my point of view;
C_TPLM30_65 : The newest SAP Certification at EAM is designed for entry- level consultants that's why
(1) All the certification about how to describe?Maintain?Customize?
(2) Don't consider some of important integration points such as: Processing External Services, all cost topics (Cost Estimation, Order Settlement, Planned/Actual Cost Determination, Plant Maintenance in the Organizational Structures of Accounting) and Capacity Planning unlike C_TPLM30_05
The advantage of this certification "C_TPLM30_65", It covers most of enhancements points related to PLM from EhP 1 : EhP 5 unlike C_TPLM30_05 which covers ONLY ECC 6.0
Hope this note helps.

Difference between Null and null?

What is the difference between null and NULL?
When is each used?
Thanks,

veryConfused wrote:
There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'
         changing
              data_tab                = iflatf
         exceptions
              file_open_error         = 1
              file_read_error         = 2

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2
