二、一些的作用说明

T163K
The 'Consumption posting' indicator and the account grouping code for the automatic account determination are read from table T163K for the account assignment category from the purchase order.
The consumption posting is empty for goods receipts that are not assigned.
The value from T163K is not always used for goods issues.
During goods issues with movement type 601, the 'Consumption posting' indicator originates from the delivery.
You can maintain the table with transaction OME9.

T156S
This table must contain an entry for the following key fields, because otherwise error message M7001 'Entry & & & not in table T156S (system error)' is displayed.
The movement type is entered in the goods receipt transactions.
The value update is stored in the detail screen for the material type, transaction OMS2.
The quantity update is stored in the detail screen for the material type, transaction OMS2.
The special stock indicator is entered in the goods receipt transaction.
The movement indicator is derived from the transaction.
Consumption posting indicator for stock transfer.
The consumption posting is selected from T163K.
For this key, important economical data such as value string and quantity string is read from T156S during a goods movement. If a value string is maintained for an entry for a material with value update, this must not be deleted because otherwise inconsistencies may occur.

T156X
If you add an entry in T156S, you must also maintain T156X. T156X has the same key fields as T156S plus value string plus numerator. The account grouping code for every entry is stored here. It is used in the automatic account determination.

T156W
The respective transaction/event keys (GBB, WRX) for the value string are maintained here. For these transaction/event keys, you must store a G/L account for the automatic account determination considering the valuation grouping code and the account grouping code (from T163K and T156X).

 关于T156S T156X T156K T156W参见：Note 34913 - The handling of tables T156S, T156X, T156W, T163K

三、举例说明ＳＡＰ是如何根据配置抛帐的（以１０１移动类型为例）
In the test case that you propose, in the goods receipt for a purchase order with the movement type 101, normally:

.- We expect an invoice to arrive, so we post to the key WRX for the GR/IR clearing account.
.- We increase the value of our stock, so we post to the key BSX for the stock account.
第一步:
In the table T156 for the Movement Type you are posting (101 in this case) you have the Posting String Reference (T156-BUSTR, in this case it is also 101).
第二步:
With this posting string reference you can have a look at the table T156SY. Here, as mentioned before, depending on:
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 post with reference to a special procedure (stock transport order, for example).
If you update consumption.
第三步:
You locate the Value String T156SY-BUSTW. For example, WE01.
第四步:
With this value string, in T156W, you can see all the possible posting keys which can be used:

BUSTW CNT02 VORSL
WE01 01 BSX
WE01 02 WRX
WE01 03 PRD
WE01 04 KDM
WE01 05 EIN
WE01 06 EKG
WE01 07 BSV
WE01 08 FRL
WE01 09 FRN
WE01 10 BSX
WE01 11 UMB
第五步:
The program coding reads this table, and determine all these possible posting keys. Then it goes into the valuation program and tries to determine a value for all of them.
第六步:
Those keys which finally get a value of zero (for example, if BSX and WRX match, no price differences are generated, so PRD gets a value of zero) are not posted, and not included in the final accounting document.

account from the table T030 according to:

SELECT SINGLE * FROM T030 WHERE KTOPL = KONTENPLAN
AND KTOSL = VORGANGSSCHLUESSEL
AND BWMOD = BEWERTUNG_MODIF
AND KOMOK = KONTO_MODIF
AND BKLAS = BEWERTUNGSKLASSE.

the chart of accounts (KONTENPLAN), the posting key (VORGANGSSCHLUESSEL), the valuation grouping code (BEWERTUNG_MODIF), the account modifier (KONTO_MODIF) and the valuation class in the material master (BEWERTUNGSKLASSE).

This table T030 is customized in OBYC.

五、配置路径说明
1) You are posting in a Plant. 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.
