Difference between repetative manufacturing and discreate manufacturing

Hi,
Guru's
What is the difference between repetative manufacturing and discreate manufacturing in product costing.

Dear Manish,
Repetitive Manufacturing
In repetitive manufacturing, master plans are typically created on a period and quantity basis (reduction in individual lot and
order-specific processing). A quantity of one product is manufactured over a certain period. The product is processed in a constant flow and interim products are generally not stocked. In repetitive manufacturing, you usually find that the effort required for production control is significantly less than is required for single lot and order-based production control and the recording of actual data is kept simpler. Repetitive manufacturing can be used for various industries, such as the
consumer packaged goods industry, the electronic industry, packaging industry, for example.
You can use Repetitive Manufacturing purely for make-to-stock production, or in a sales order-oriented environment, such as found in the automotive industry.
Discrete Manufacturing
Discrete manufacturing is characterized by requirements that occur on an irregular basis and a workshop-oriented process.
The Discrete Manufacturing scenario can be used in different variants, production by lot size, make-to-order production and assembly processing. The variants differ mainly in the type of planning conducted before-hand and in the relation to the sales order. Production by lot size is identified by the grouping of requirements into lots during requirements planning, and by planning with existing basic data. Production by lot size is independent of a particular sales order. Make-to-order production describes the production of a material with reference to a particular sales order. The manufactured quantities are managed, in terms of stock, directly for the individual sales order. They cannot be exchanged with the stock of other sales orders. Starting from the sales order, single-item planning can be allowed as far down the bill of material (BOM) structure as you like. Assemblies and
components can also be procured for the sales order that generates the requirements, and managed in stock for this sales order. If the product is a configurable product, the system chooses a variant for the customer based on the characteristics that he or she selects. A sales order BOM can then be generated for the sales order. This BOM is used to produce the product.
Assembly processing is a form of make-to-order production, in which the production order (assembly order) is created together with the sales order. In assembly processing the components for the product have, in general, already been produced. They only need to be assembled. The advantage of assembly processing is that an availability check is carried out for the components when you create the sales order. This increases the reliability with which dates can be confirmed
considerably. Changes to the sales order are automatically also made in the production order and vice-versa.
And also you can follow the below link to know more about REPITITIVE MANUFACTURING its a pdf document from help.sap.com
http://help.sap.com/printdocu/core/print46c/en/data/pdf/PPREM/PPREM.pdf
One More Example
Repetive is usually a continuos flow, good example is making 5000 tv dinners you know how long it takes to make qty1 very little defects or fall out and you always have everything on hand to start the run, you may also make the same run 2-3 times per month so a cost collector is ok all cost go to top level.
Discreet, You do have falls out reworks and move into production missing materials, long lead time its essential to know what and where it is at in production, cost may vary a little but each production order will be costed independantly for review.

Difference between Service BOM and Manufacturing BOM

One fundamental question
What is the difference between Service BOM and Manufacturing BOM. Also what is the difference between Manufacturing BOM and Engineering BOM.
Why should a business create these 3 kinds of BOM's for their operations. cant 1 kind of BOM suffice ?

This is a business definition that your business people should be able to tell you.
Both are BoMs - it's just a question of which parts are defined under each category.
Usually, "Service" BOMs are created by service org personnel as and when required, eg at new item introduction or new option introduction.
"Manufacturing" BoMs are created by Engineering personnel and are the ones used when creating an order for a machine.
Hope that it helps.
Cheers,
TC

Difference between business area and sales area

Hi
I am swetha i have one doubt
1) what is the buisiness area and what purpose we use the business area
2) what is sales area and what purpose we use the sales area
3)what is the main Difference between business area and sales area.
Regards
Swetha

Hii..
Business Areas in SAP are used to differentiate transactions originating from different points/lines/locations in business. Let me give some examples to elucidiate:-
A company (say, ABC) is a huge company and has a variety of businesses under it. Let us say that it typically operates in 3 different domains like machinery manufacturing, trading and assembling of machine parts.
There are 2 options here now -
1. Either create different company codes for the 3 business operations (which would be the easiest and require no creativity)
or
2.) Create each of these business lines into business areas (the better option).
The advantages of using the second option is:
1. You can use these business areas if other company codes require the same areas
2. The configuration is simpler as in case of company code, you would require to go through the entire configuration of creating Chart of Accounts, Fiscal Year variants, posting periods variants and so on. In the business area option, you just need to attach it to the company code and the rest of the details in Business area is attached by default from the company code you are using it in.
3. Using the options in controlling (EC-PCA, Enterprise Controlling, Profit Centre Accounting), you can even draw up Balance Sheets and PL statements for your business areas and hence this is used for management accounting in some companies (like HP, Dell, etc) when it wants to know the operating profits for different business areas/lines.
The above was an example when the company wanted to separate entries according to the lines it operates in... the other case could be when it wants to find out profitability during its operations in cities and differentiates these cities into Business
Areas...
Business Areas are not much relevant in FI but are much more relevant in CO.
Hope this clears.

Troubleshooting hints - differences between development environment and release environment

Hello,
I am using LabVIEW 8.6 for an application involving stepper motors. We are using 2 Velmex stepper motor systems to run PIR targets for a manufacturing test. The problem I am having is that the program runs fine in the states where it was developed but hangs approximately every 10th run when running in the manufacturing environment in China. Since I am on the EAst coast there is the 12 hour time delay, and I am planning on doing a live support call to find out what is going on. The person who installed the code made some modifications, but I am not aware of the differences. He also may send his code here and see how it runs.
The assumption I am making (based on past experiences from here in the States) is that the stepper motor interface is hanging. since I can't recreate the problem here I can't troubleshoot it.
With a past prooject I was working I did some code on one machine, and when I ran it on a different machine the order of execution for items in a sequence was different between the machines. Has anyone run into this before? Unfortunately for the task at hand the stepper motor has to run at the same time that analog data on multiple channels are being acquired.
Any suggestions?
Mike
Mike

Thanks for the reply. I did think about putting in a producer-consumer. It turns out that there was a problem with the computer it was being run on. The computer was changed and the problem got better, although it did not go away. The stepper motor was done through a com port talking to another hardware / software solution. The tasks are truly independent and pass no data between them. However, the other task being run involves collecting analog data and updating on a chart (and in one instance stimulating an analog output), and when the stepper motor starts the analog data collection is not updated on the chart. I figure this could be because the charts are a memory hog. No data is lost, and it is running, so I figure if it's not broke don't fix it. It now occasionally locks up. I can run it here for 100 times with zero lock ups, and the last report I got was it ran 30 times in china before locking up. I may have to start examining differences between their machine and my machine.
Now as to the configuration management. It needs to be clarified a wee bit. I'm doing the initial code development / updating, and then we hand off to china, which can make code tweaks as needed. They also have 3 lines running this program, and one of the items I did was to load the differences between lines from configiration files (INI files), and that I got working well. We have fixture variables, items that vary between lines, and configuration items, which are I/O lines and what not. The digital I/O and analog I/O referenced MAX tasks, and that worked well. There are also a com port call for the stepper motor, and in another program an RF power meter, which had to be referenced from an INI file. I will reccomend that they do their code development on one machine and create executables to store on the production lines. We have been bouncing code back and forth from the team members from the states that are currently in china doing the install.

Differences between rate routing and reference rate routings?

Hello PP members:
I would like to differences between rate routing and reference rate routings
Thanks for your time,
Thanks Again,
Suren R

Hi Mr.Suren,
As explained by other friends Routing is used in Discrete manufacturing and Rate routing is used for REM-Repetitive manufacturing.
In addional to these types SAP has given 2 more types
1.Reference operation set -Used in Discrete manufacturing.
2.Reference rate routing - Used in REM.
If similar rate routing is been used for producing many materials,then instead of entering(these steps) in rate routing of each material you create a refrence rate routing and you enter the work centres used and the other details.After saving you get a group counter number showing reference rate routing is saved with group XXXXXXXXX.
When you are creating rate routing for a material say A ,after giving the name and plant details in the top you will be able to see an icon "copy from" and you can select the radio button for reference rate routing and give the group counter number. or else without giving it here you have got an option to select the reference rate routing after entering into the operation screen also.
In that particular page in operation overview screen,there will be an icon copy,there you can click that icon and you can give the reference rate routing group counter number and very easily you can create rate routing for N number of material.
Likewise you can use reference operation set while creating routing for a material in Discrete manufacturing.This basically reduces the time in creating routing or rate routing for materials in Discrete & REM respectively
CA01,CA02,CA03-Create,Change,display (routing) respectively.
CA11,CA12,CA13-Create,Change,Display reference operation set Respectively.
CA21,CA22,CA23-Create,Change,Display rate routing respectively.
CA31,CA32,CA33-create,change,display reference rate routing resp.
I hope this will help you.
If useful reward your points.
Thanks & regards
Karthik.

Difference between process order and Production order

Hi Experts,
Can any buddy tell me the difference between process order and production order. Why process order is used for process industries. Why do we use recipe for it and routing for production order ?
Regards,
Amit

Hi Amit
There is a difference between production order and process order.
Supposing a 10,000 lit tank is being manufactured in discrete manufacturing. You have to follow the necessary routing steps and can make by physically seeing its development stage by stage. For this type production you can have a production order.
In case of process of order if some chemical in a reactor is loaded with intial temp of 30 C and need to be heated to 80 C then there is phase change. Hence we use Heating as an operation and the change of temp is phase. For such type of process we process order.
Hope this is useful. Pl reward.

Difference between Standard cost and standard price

Hi:
I have gone through google but i could not find any answer to the question clicking my mind. When we talk about standard cost and standard price..Should they be taken synonymously? Are these two same concepts... If there is any difference between two please do let me know..Similarly is there any difference between Actual cost and actual price. Please guide
Br

For Finished Goods, Cost is nothing but your manufacturing or procurement cost.
Where as Price is nothing but your sales price of the same Finished Goods.
Simply when you buy, it is cost and when you sell it is price.
Price includes cost + Profit or loss.
But from SAP point of view Standard Price field in Material master is Standard Cost.
Standard cost will be arrived when we manufacture or procure
Sale price will be entered in Sale order as condition value.

Difference between Standard Pricing and Moving Average Price

Hi,
Would like to seek some advises on the difference between standard price and Moving average price.
also, how does it affect the account postings differently?
Thanks

Standard Price
Materials whose price control indicator is set to S are valuated in Financial Accounting (FI) at standard price.
This is recommended for semifinished products and finished products.
The moving average price is shown as a statistical value in the material master record.
The standard price is normally calculated using a standard cost estimate for the material. The standard price can also be calculated in a mixed cost estimate.
Moving Average Price
When materials whose price control indicator is set to V are received from in-house manufacturing processes, they are initially valuated with a value you defined (such as the standard price). When you settle, the material stock account is debited with the variances. This results in a new moving average price.
Valuating semifinished products and finished products with the moving average price is not recommended.
Regards,
Indranil

Difference between Material type and Item category

What is the difference between Material type and Item category?
We can differentiate different kind of materails according to material type then why do we have Item category which is also more or less on the same lines.
Both can be considered as a terminology in SAP to group similar kind of materials.
Please let me know the exact difference between the two?

Dear Christino
We can list out so many differences.
When you create a material master record, the material type you choose determines:
- Whether the material is intended for a specific purpose, for example, as a configurable material or process material
- Whether the material number can be assigned internally or externally
- The number range from which the material number is taken
- Which screens appear and in what sequence
- Which departmental data you may enter
- What procurement type the material has; that is, whether it is manufactured in-house or procured externally, or both
Together with the plant, the material type determines the material's inventory management requirement; that is:
- Whether changes in quantity are updated in the material master record
- Whether changes in value are also updated in the stock accounts in financial accounting
In addition, the accounts affected by a material entering or leaving the warehouse depend on the material type.
-Most importantly, Users can be authorized to create materials of specific material types but not based on item category
- Item category will define whether the material should be valuated for stock or it should be considered as non-stock
- Pricing is carried out based on Item Category and not based on Material type

Difference between WEP, WPA, and WPA2 and better suggestion to use for shared family users

What is the difference between WEP, WPA, and WPA2? My router is set up on my family PC and connected to a modem so I access Wi-fi through my laptop and my sister has a laptop too and uses our family network to get internet. I just set up a WPA today, so will we all be able to get internet (along with my family using the pc, and my sis on her laptop, even at the same time) protected? (like nobody else using our network)

Wired Equivalent Privacy, commonly called WEP is 802.11's first hardware form of security where both the WAP and the user are configured with an encryption key of either 64 bits or 128 bits in HEX. So when the user attempts to authenticate, the AP issues a random challenge. The user then returns the challenge, encrypted with the key. The AP decrypts this challenge and if it matches the original the client is authenticated. The problem with WEP is that the key is static, which means with a little time and the right tool a hacker could use reverse-engineering to derive the encryption key. It is important to note that this process does affect the transmission speed.
WPA builds upon WEP, making it more secure by adding extra security algorithms and mechanisms to fight intrusion.
WiFi Protected Access (WPA) is the new security standard adopted by the WiFi Alliance consortium. WiFi compliance ensures interoperability between different manufacturer’s equipment.WPA delivers a level of security way beyond anything that WEP can offer, bridges the gap between WEP and 802.11i networks, and has the advantage that the firmware in older equipment may be upgradeable.
WPA2 is based upon the Institute for Electrical and Electronics Engineers’ (IEEE) 802.11i amendment to the 802.11 standard, which was ratified on July 29, 2004. The primary difference between WPA and WPA2 is that WPA2 uses a more advanced encryption technique called AES (Advanced Encryption Standard), allowing for compliance with FIPS140-2 government security requirements.

Difference between varient configuration and super bom

hi gurus
i want to know the difference between varient configuration and super bom??
i think as per my knowledge it is same.
but my friend says both are different.
award points
enjoy

hi,
Variant Configuration : You do not need to create a separate material for each variant of a product in your company. You can use one configurable material to cover all variants. You create a super BOM and a super routing for this material, containing all the components and operations for producing all variants of the product.
Super BOM : The bill of material (BOM) of a configurable material contains all the components that are required to manufacture the material. The BOM contains components that are only used in specific variants (variant parts), as well as components that are used in all variants (non-variable parts).
<b>This is why BOMs for configurable materials are known as super BOMs.</b>
Thanks

Difference between Olant sale and Depot sale

What is the basic difference between plant sale and depot sale? is there any difference with respect to their confighration part?

Hi !
With regards to your query, as per the business requirements of a company a company can have depots and plants for retail sales , and sales directly to customers from manufacturing plants.
For this there can be different codes for depots locations and plants and different storage locations respectively.
Also pricing may vary both for raw materials and FG, since manufacturing might be carried out under a contract agreement,scheduling agreement etc and retail sales may be at standard market rates.
Thus the pricing procedures would vary.
The norms for customer account groups and credit exposure would also vary.
Plz reward points if helpful.

Difference between production version and routing

hello pp experts,
                        why do we create production version, and what's the difference between production version and routing?

Dear sarfaraz lodhi ,
Production version is a combination of BOM & Routing in the case of Discrete Manufacturing and it's a
combination of BOM & Rotuing/Rate Routing in the case of Repetitive Manufacturing.
Created either through MM02 by selecting MRP4 view or else through C223
A production version determines the various production techniques that can be used to produce a material.
It defines the following information:
·        Alternative BOM for a BOM explosion
·        Task list type, task list group, and group counter for assignment to task lists
·        Lot-size restrictions and period of validity
A material can have one or more production versions.
Routing contains the set of operation that's required for producing a product either a HALB - Semi-
Finished product or else a FERT - Finished Product.
The T code for creating Routing is CA01.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.
