You specify whether valuation occurs at plant or
company code level in transaction OX14
(Define Valuation Level). Then whichever one you have defined becomes a
Valuation Area. These areas can be grouped together for ease of account
assignment, in which case they become valuation groups.
Account Category Reference codes are associated to
Valuation Classes are associated to material types in
Also an explicit association of Account Category
Reference number to Valuation Class is made in Account Determination.
For example, Material HALB - Semifinished Goods.
Account Category Ref in Material Type is 0008. Valuation Class 7900 is linked
to Account Category Reference 0008.
When a material is created, it is associated to the
appropriate Valuation Class on Accounting View 1 of Material Master.
The automatic account determination facility looks up a
posting based on the rules defined - whether to look at only Valuation Class, or
Valuation Class and an additional Valuation Modifier for BSX postings for
example. It will check the rules, look at the material, material type and
valuation area and the rules for the movement itself (where the system is
expecting to see the account definitions). All of the definitions need to be
consistent. If you've defined a new Account Category Reference, you need to
make sure that's associated to the Valuation Class and Material Type.
The fastest and best way to tell if something is going
to post the way you want it to is to simulate the posting. You can do that in
the initial screen with the simulate button. Choose the plant, the movement
type and the system will ask for a material and then tell you where everything
will post, or if there's a posting account that is missing.
