Plant 0001 is the SAP default.
OX14 - Define Valuation Area (Tick one only- Once your system go live, no more changes)
Most company take the SAP recommended choice - Value Material Stock at Plant level
Value Material Stock at Plant or Company Level
- If you valuate material stocks at plant level, the plant is the valuation area.
- If you valuate material stocks at company code level, the company code is the valuation area.
- The decision you make applies to the whole client.
- Create / Change / View Plants
OVXB - Create / Change / View Division
OX18 - Assign Plant to company code
e.g. 0001 - 0001 - All Plants
Px1 - Plant Px1
Px2 - Plant Px2
OX19 - Assignment of company code to the Controlling Area
OB38 - Assign company code to Credit Control Area
OMJ7 - Assign business area to Plant/Valuation area and division
e.g. Plant Px1 - Business Area Bx1
Assign Valuation area to the Business Area
.e.g. Valuation area Vx1 - Business Area Bx1
Business Area Bx2
OMS0 - Assign Factory Calendar to the Plant and Business Area
The plant plays an important role in the following areas:
- Material Valuation - If the valuation level is the plant, the material stocks are valuated at plant level. Each plant can have its own material prices and account determination.
- Inventory Management - The material stocks are managed within a plant.
- MRP - Material requirements are planned for each plant. Each plant has its own MRP data. Analyses for materials planning can be made across plants.
- Production - Each plant having they own production/planning.
- Costing - In costing, valuation prices are defined only within a plant.
- Plant Maintenance - If a plant performs plant maintenance planning tasks, it is defined as a maintenance planning plant. A maintenance planning plant can also carry out planning tasks for other plants (maintenance plants).
If you want to use the application PP (production planning) or product costing and job-order costing, you must set valuation at plant level.
The valuation level that you choose affects
- the maintenance of material master records
- the G/L accounts in which material stocks are managed
- the G/L accounts to which transactions are posted in Materials Management
Effect on the maintenance of material master records:
Depending on the valuation level chosen,
- you maintain accounting data in the material master record for each plant or for each company code
- you define a valuation price for the material in each plant or in each company code
Effect on G/L accounts:
If material stocks are valuated at company code level, all plant stocks of a material are managed in a joint stock account for each company code.
If material stocks are valuated at plant level, you can manage the material stocks for each plant in different accounts. For each plant, you can define a separate determination.
If several plants are to use account determination, you can group these plants in "Valuation and Account Assignment" Customizing.
Material Master - Introduction
The material master is the starting point for the rest of the modules.
What Material Types are there?
The material types that you use are configured in Customizing for the Material Master under
Logistics Master Data : Material Master -> Material -> Control data -> Define material type attributes.
The following list shows you the material types contained, for example, in the standard SAP R/3 System, and what their different roles are:
Services are procured externally and cannot be stored. A material master record of this material type can always contain purchasing data.
FERT (finished products)
Finished products are produced by the company itself. Since they cannot be ordered by Purchasing, a material master record of this material type does not contain purchasing data.
FHMI (production resources/tools)
Production resources/tools are procured externally and used in the manufacture of products. A material master record of this material type can contain purchasing data, but no sales data. It is managed on a quantity basis. Examples of production resources/tools are apparatus, equipment, and measuring and testing devices.
HALB (semifinished products)
Semifinished products can be procured externally (sub-contracting) as well as manufactured in-house. They are then processed by the company. A material master record of this material type can contain both purchasing and work scheduling data.
HAWA (trading goods)
Trading goods are always procured externally and then sold. A material master record of this material type can contain purchasing and sales data.
HIBE (operating supplies)
Operating supplies are procured externally and required for the manufacture of other products. A material master record of this material type can contain purchasing data but no sales data.
NLAG (non-stock material)
Non-stock material is material that is not held in stock because it is consumed immediately. (Office supplies such as stationary. You need to create purchase order and accounting document for payment but the stock balance is always zero as it is issued out immediately to the various department.)
ROH (raw materials)
Raw materials are always procured externally and then processed. Since raw materials cannot be sold, a material master record of this material type contains no sales data.
UNBW (non-valuated materials)
Non-valuated materials are managed on a quantity basis, but not by value.
VERP (packaging materials)
Packaging materials are used to transport goods and come with the goods free of charge. A material master record of this material type is managed both on a quantity basis and by value.
WETT (competitive products)
Competitive products have their own material master records created from the Basic Data view. The competitor's number, which is stored in the material master record, assigns the material to a particular competitor.
Maintain the Material Type
OMS2 - Material Type Maintenance - Create/Change/Display
- transaction OMS2
- click Change
- key in the Material Type you want to change e.g. FERT then hit enter
The Views belows allows you to choose the Views for each Material Type.
(Press the Page up/Page Down
keys to scroll the views)
If you tried to change from FERT to HAWA in 4.6x, you will receive an error message :-
The material type cannot be changed. This is not allowed if only external procurement is defined for the new material type, or if the new material type has a different account category reference than the old material type.
To overcome it, goto OMS2 and change the HAWA material type.
In the Internal/external purchase orders sections:
Ext. purchase orders 2 1
Int. purchase orders 0 1
Screens in Material Master
- MM01 - Create, MM02 - Change, MM03 - Display and MM06 - Flag for deletion.
- MM04 - Display the changes done to the material master.
- MMAM - Change the Material Type. for e.g. from FERT to HALB
Configure the Material Master Screen MM01 / MM02 / MM03
OMSR - Assign the field to the field group
OMS9 - Maintain the data screen field
Unit of Measure
In the material master, there is a Units of measure button for users to store in the different conversion rate. This sample program (ZUNT) extract the data from the unit of measure conversion table.
In the Material Master the moving average price are affected by:-
Common configuration changes-
- Goods Receipt for Purchase Orders
- Transfer from Plant to Plant
- Invoice Receipt
- Price Change
- define new material group (OMSF)
- define new valuation class (OMSK) and automatic posting (OBYC)
- define new material account assignment group (transaction OVK5) and
Customer/Material/Account keys (transaction VKOA)
Block materials from inventory posting
After blocking, when the user do a inventory posting, they will get this error message :-
E: Material xxxxx has status Blocked for procmnt/whse
To activate the blocking :-
Goto transaction MM02 - Purchasing View
Type in 01 at the MM/PP status field and save it
Create Delivery Log - Material xxx is blocked
During the Create Delivery (VL01), SAP prompt you a log that Material xxx is blocked.
During the Sales Order Create/Change for that material, there might be some update termination that causes the locked of the material (Windows hanged or power failure).
You can check using transaction SM12 - type an "*" at the User name field.
Check whether the material is in the locked list.
If it is in the locked list, asked the user to log out before you delete it from the locked list.
Maintain Storage Location
MMSC - Collective entry of Storage Location for a material.
Insert new or delete un-used Storage Location.
Maintain whether the storage location was included or excluded from MRP run.
Block Storage Location from further posting
1. You can block the storage location of a material without affecting the rest of the location using the same material.
Create a Physical Inventory document for the storage location with transaction MI01
Select the Posting Block checkbox.
This would prevent transactions from occuring until you either post or delete the physical inventory document.
(There are no impact, unless you do a post difference for the physical inventory document.)
2. Another method is to rename the storage location name.
Go to transaction OX09
Edit -> Copy as (copy the original storage location to a new name, replacing the first character e.g. ZXXX)
Edit -> Delete (delete the original storage location)
Do the reverse if you want back the original storage location.
Accounting document number range for MM
Document Type - Double click on desire transaction code to check the document type for number range.
(e.g. MR21 Document type - PR)
Financial accounting document type - Assign the document type to a number range and account type.
(e.g. PR - Account type allowed for posting will be MS)
- Double click on the document type PR.
- Assign an unique starting number range that was not used. e.g. 88
- Choose the Account type for Material and G/L account (MS)
- The rest of the fields are optional (you can leave it as blank)
SAP definitions for account type -
Number ranges for financial accounting document type
- A - Assets
- D - Customers
- K - Vendors
- M - Material
- S - G/L accounts
- Assign the number range to the running number range.
No. Year (till) From number To number Current number Ext (no tick internal or tick external)
88 9999 8800000000 8899999999 Track by SAP Blank
Accounting document will be generated if there are stocks during price change, if you don't have any stocks, no accounting document will be generated as there are no inventory to revaluate for price differences.
Valuation Class for Material Group
In 4.6x and 4.5b, you can assign valuation class to Material Group.
It is useful in the sense that user do not have to manually do an Account Assignments.
For stock items, valuation class cannot be changed whenever the stock on hand is not zero.
Valuation class are tied to a G/L account.
A change of valuation class means a change of G/L account.
In FI concept, you have to debit and credit to balance the G/L account. That is why your stock must be zero before the system allows you to changed the valuation class. If it is not zero, you have to either transfer it to another material or do a dummy issues. After changing the valuation class, do a reversal entries for the stocks which you have transfer out or you have done a dummy issues.
