OBYC - MRX (GR/IR clearing account)

Question

Hi all,
Could anyone explain the following:
1) Valuation Modifier
2) General Modification
3) Valuation Class
4) Account
As per the following url:
http://www.sap-img.com/financial/what-is-valuation-area-and-class.htm
===========
Valuation areas are nothing but the level at which you want to valuate your materials. SAP provides two levels of valuation Plant level and company code level.
For example:
Valuation at plant level: Suppose you have two plants one in Hissar and one in Andhra Pradesh, Then of course you would like to valuate the rawmaterials at plant level as because you have got transportation cost and taxes etc to account for.
Valuation at company code level:Here you valuate all your material in same way.
In One client valuation areas can either be set to plant level or company code level. Once you have made this setting this cant be changed
Valuation classes are linked to valuation class in Tcode OBYC
If your valuation area is at plant level then in OBYC you will find a coloumn for Valuation modifier you can provide your plant there.
===========
My question:
1) Valuation Modifier - where we can define this / what is the function of this?
2) General Modification - where we can define this / what is the function of this?
3) Valuation Class -  what is the function of this?
4) Account - N/A

Answer 1

Hi
1) Valuation Modifier - where we can define this / what is the function of this?
SPRO-> Materials Management-> Valuation and Account Assignment-> Account Determination Without Wizard-> Group Together Valuation Areas
Indicates a grouping of valuation areas to facilitate the administration of the table of standard accounts by minimizing the number of entries.
Together with other factors, the valuation grouping code determines the G/L accounts to which a goods movement is posted ( automatic account determination).
2) General Modification - where we can define this / what is the function of this?
Key that has a different meaning depending on the business transaction and which is used to differentiate account determination. The meaning is preset in the SAP System and cannot be changed.
When making offsetting entries for inventory postings, you enter the the key which is assigned to the transaction type and posting string.
These keys cannot be created these are SAP standard.
You can create the keys if you create a new movemnt type.
3) Valuation Class - what is the function of this?
The valuation class has the following functions:
Allows the stock values of materials of the same material type to be posted to different G/L accounts.
Allows the stock values of materials of different material types to be posted to the same G/L account.
Determines together with other factors the G/L accounts updated for a valuation-relevant transaction (such as a goods movement).
4) Account - N/A
The G/L account number identifies the G/L account in a chart of accounts.
General Ledger account is a structure that records value movements in a company code and represents the G/L account items in a chart of accounts.
Thanks & Regards
