The Plant is assigned in OX18 to a Company Code.
The Company Code is assigned in OB62 to a Chart of Accounts.
You take here the Chart of Accounts for your Company Code.
2) Under the IMG:
Materials Management -> Valuation and Account Assignment
-> Account Determination -> Account Determination Without Wizard -> Define
Valuation Control - You define whether you want your Plants to be grouped
together or treated individually.
Then, in the next customizing step to "Group Together Valuation Areas", you can see to which group you have assigned the Plant. This is the Valuation Grouping Code.
3) The Valuation class is defined in the Accounting 1 view of your Material Maser.
4) The account modifier is used in some posting keys like GBB, PRD or KON to subdivide the account determination.
You can see in the activity "Define Account Grouping for Movement Types" the different account modifiers to be used in these posting keys.
You need to know:
- The movement type.
- If you are posting into the special stock.
- If value update and quantity update are made (see the
material type for the material in the table MARA and then check OMS2 for
the Plant).
- If you post with reference to a document (purchase
order, etc).
- If you update consumption.
Once you have all this info, you can find the account in OBYC
