Answer 1

Read the details as below for your Understanding..
You can find the document by going SPRO > Materials Management > Valuation and Account Assignemtn > Configure Automatic Postings.
Configure Automatic Postings
In this step, you enter the system settings for Inventory Management and Invoice Verification transactions for automatic postings to G/L accounts.
You can then check your settings using a simulation function.
Under Further information there is a list of transactions in Materials Management and their definitions.
What are automatic postings?
Postings are made to G/L accounts automatically in the case of Invoice Verification and Inventory Management transactions relevant to Financial and Cost Accounting.
Example:
Posting lines are created in the following accounts in the case of a goods issue for a cost center:
Stock account
Consumption account
How does the system find the relevant accounts?
When entering the goods movement, the user does not have to enter a G/L account, since the ERP system automatically finds the accounts to which postings are to be made using the following data:
Chart of accounts of the company code
If the user enters a company code or a plant when entering a transaction, the ERP system determines the chart of accounts which is valid for the company code.
You must define the automatic account determination individually for each chart of accounts.
Valuation grouping code of the valuation area
If the automatic account determination within a chart of accounts is to run differently for certain company codes or plants (valuation areas), assign different valuation grouping codes to these valuation areas.
You must define the automatic account determination individually for every valuation grouping code within a chart of accounts. It applies to all valuation areas which are assigned to this valuation grouping code.
If the user enters a company code or a plant when entering a transaction, the system determines the valuation area and the valuation grouping code.
Transaction/event key (internal processing key)
Posting transactions are predefined for those inventory management and invoice verification transactions relevant to accounting. Posting records, which are generalized in the value string, are assigned to each relevant movement type in inventory management and each transaction in invoice verification. These contain keys for the relevant posting transaction (for example, inventory posting and consumption posting) instead of actual G/L account numbers.
You do not have to define these transaction keys, they are determined automatically from the transaction (invoice verification) or the movement type (inventory management). All you have to do is assign the relevant G/L account to each posting transaction.
Account grouping (only for offsetting entries, consignment liabilities, and price differences)
Since the posting transaction "Offsetting entry for inventory posting" is used for different transactions (for example, goods issue, scrapping, physical inventory), which are assigned to different accounts (for example, consumption account, scrapping, expense/income from inventory differences), it is necessary to divide the posting transaction according to a further key: account grouping code.
An account grouping is assigned to each movement type in inventory management which uses the posting transaction "Offsetting entry for inventory posting".
Under the posting transaction "Offsetting entry for inventory posting", you must assign G/L accounts for every account grouping, that is, assign G/L accounts.
If you wish to post price differences to different price difference accounts in the case of goods receipts for purchase orders, goods receipts for orders, or other movements, you can define different account grouping codes for the transaction key.
Using the account grouping, you can also have different accounts for consignment liabilities and pipeline liabilities.
Valuation class of material or (in case of split valuation) the valuation type
The valuation class allows you to define automatic account determination that is dependent on the material. for example: you post a goods receipt of a raw material to a different stock account than if the goods receipt were for trading goods, even though the user enters the same transaction for both materials.
You can achieve this by assigning different valuation classes to the materials and by assigning different G/L accounts to the posting transaction for every valuation class.
If you do not want to differentiate according to valuation classes you do not have to maintain a valuation class for a transaction.
Requirements
Before you maintain automatic postings, you must obtain the following information:
1. Valuation level ( plant or company code)
Establish whether the materials are valuated at plant or at company code level
When valuation is at plant level, the valuation area corresponds to a plant.
When valuation is at company code level, the valuation area corresponds to a company code.
Define valuation level
2. Chart of accounts and valuation grouping code per valuation area
Find out whether the valuation grouping code is active.
Activate split valuation
If it is not active, determine the chart of accounts assigned to each valuation area (via the company code).
If it is active, determine the chart of accounts and the valuation grouping code assigned to each valuation area.
Group valuation areas
You must define a separate account determination process for chart of accounts and each valuation grouping code.
3. Valuation class per material type
If you wish to differentiate the account determination process for specific transactions according to valuation classes, find out which valuation classes are possible for each material type.
Define valuation classes
4. Account grouping for offsetting entries to stock accounts
Under Define account grouping for movement types, determine for which movement types an account grouping is defined for the transaction/event keys GGB (offsetting entry to stock posting), KON (consignment liabilities) and PRD (price differences).
Stock posting (BSX)
This transaction is used for all postings to stock accounts. Such postings are effected, for example:
In inventory management in the case of goods receipts to own stock and goods issues from own stock
In invoice verification, if price differences occur in connection with incoming invoices for materials valuated at moving average price and there is adequate stock coverage
In order settlement, if the order is assigned to a material with moving average price and the actual costs at the time of settlement vary from the actual costs at the time of goods receipt
Because this transaction is dependent on the valuation class, it is possible to manage materials with different valuation classes in separate stock accounts.
Caution
Take care to ensure that:
A stock account is not used for any transaction other than BSX
Postings are not made to the account manually
The account is not changed in the productive system before all stock has been booked out of it
Otherwise differences would arise between the total stock value of the material master records and the balance on the stock account.
Account determination of valuated sales order stock and project stock
Note that for valuated sales order stock and project stock (special stock E and Q) and for the transaction/event keys BSX and GBB, you must maintain an account determination to avoid receiving warning messages when entering data (purchase order or transfer posting) for valuated stock.
During data entry, the system attempts to execute a provisional account determination for GBB for valuated stock. The system will only replace the provisional account determination for GBB with the correct account determination for the stock account (BSX), in the background, if you enter the data for valuated stock at a later point in time.
Revaluation of other consumption (COC)
This transaction/event key is required for the revaluation of consumption in Actual Costing/Material Ledger.
Revaluation of consumption valuates single-level consumption using the actual prices determined in the Actual Costing/Material Ledger application. This revaluation can either take place in the account where the original postings were made, or in a header account.
The header account is determined using the transaction/event key COC.
Del credere (DEL)
Transaction/event key for the payment/invoice list documents in Purchasing. The account key is needed in the calculation schema for payment/settlement processing to determine the associated revenue accounts.
Small differences, Materials Management (DIF)
This transaction is used in Invoice Verification if you define a tolerance for minor differences and the balance of an invoice does not exceed the tolerance.
Purchase account(EIN), purchase offsetting account (EKG), freight purchase account (FRE)
These transactions are used only if Purchase Account Management is active in the company code.
Note
Due to special legal requirements, this function was developed specially for certain countries (Belgium, Spain, Portugal, France, Italy, and Finland).
Before you use this function, check whether you need to use it in your country.
Freight clearing (FR1), provision for freight charges (FR2), customs duty clearing (FR3), provision for customs duty (FR4)
These transactions are used to post delivery costs (incidental procurement costs) in the case of goods receipts against purchase orders and incoming invoices. Which transaction is used for which delivery costs depends on the condition types defined in the purchase order.
You can also enter your own transactions for delivery costs in condition types.
External service (FRL)
The transaction is used for goods and invoice receipts in connection with subcontract orders.
If the account assigned here is defined as a cost element, you must specify a preliminary account assignment for the account in the table of automatic account assignment specification (Customizing for Controlling) in order to be able to post goods receipts against subcontract orders. In the standard system, cost center SC-1 is defined for this purpose.
External service, delivery costs (FRN)
This transaction is used for delivery costs (incidental costs of procurement) in connection with subcontract orders.
If the account assigned here is defined as a cost element, you must specify a preliminary account assignment for the account in the table of automatic account assignment specification (Customizing for Controlling) in order to be able to post goods receipts against subcontract orders. In the standard system, cost center SC-1 is defined for this purpose.
Offsetting entry for stock posting (GBB)
Offsetting entries for stock postings are used in Inventory Management. They are dependent on the account grouping to which each movement type is assigned. The following account groupings are defined in the standard system:
AUA: for order settlement
AUF: for goods receipts for orders (without account assignment)
and for order settlement if AUA is not maintained
AUI: Subsequent adjustment of actual price from cost center directly
to material (with account assignment)
BSA: for initial entry of stock balances
INV: for expenditure/income from inventory differences
VAX: for goods issues for sales orders without
account assignment object (the account is not a cost element)
VAY: for goods issues for sales orders with
account assignment object (account is a cost element)
VBO: for consumption from stock of material provided to vendor
VBR: for internal goods issues (for example, for cost center)
VKA: for sales order account assignment
(for example, for individual purchase order)
VKP: for project account assignment (for example, for individual PO)
VNG: for scrapping/destruction
VQP: for sample withdrawals without account assignment
VQY: for sample withdrawals with account assignment
ZOB: for goods receipts without purchase orders (mvt type 501)
ZOF: for goods receipts without production orders
(mvt types 521 and 531)
You can also define your own account groupings. If you intend to post goods issues for cost centers (mvt type 201) and goods issues for orders (mvt type 261) to separate consumption accounts, you can assign the account grouping ZZZ to movement type 201 and account grouping YYY to movement type 261.
