MM CONFIGURATION TIPS

Maintain Plant

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.
OX10 - 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 Bx2

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:

DIEN (services)
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

Steps:-

  • 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:
Original Changes
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:-

  • Goods Receipt for Purchase Orders
  • Transfer from Plant to Plant
  • Invoice Receipt
  • Settlement
  • Price Change
Common configuration changes-
  • 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

Transaction OMW9

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
  • A - Assets
  • D - Customers
  • K - Vendors
  • M - Material
  • S - G/L accounts
Number ranges for financial accounting
document type
- Assign the number range to the running number range.

No. --> 88
Year (till) --> 9999
From number --> 8800000000
To number --> 8899999999
Current number -->Track by SAP
Ext (no tick internal or tick external) --> 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.
