Where we can find the detail infomation about the Value String of automatic?
such as WE06,WE01 and so on.

Answer 1

Hai,
           Value string keys are for SAP internal usage. It is just a pointer to the transaction event key which is necessary for automatic account determination.
           Movement types are linked to transaction keys via valuation string in OMWN T-code.
           The R/3 System automatically determines the value string assigned to a specific transaction. It depends partly on entered parameters manually and partly on parameters derived internally by the system. The value string contains all posting transactions that are possible for a certain transaction. The program decides which of these posting transactions lead to G/L account postings in individual cases. You cannot define this in Customizing.
Value string WE01, for the goods receipt for a purchase order into stock, contains transactions BSX and WRX.
WE01: BSX, WRX, PRD, KDM, EIN, EKG, BSV, FRL, FRN, BSX, UMB.
WA14: BSX ,PRD, BSX, UMB
WA01: BSX, GBB, PRD, BSX, UMB
Value string RE05 contains transactions BSX and UMB.
In the standard system, value string WE01 is assigned to goods receipts (and also cancellations and return deliveries) for Standard and Subcontracting purchase order items without account assignment concerning valuated material into stock. In the case of (valuated) goods receipts for purchase order items not subject to account assignment,
post the items to a stock account using the transaction key BSX and make an offsetting entry to a GR/IR clearing account. A price difference posting (transaction key PRD) is only used if the valuated material is subject to standard price control and if the order price (or invoice price) is different from the standard price. Transaction key KDM is required in Inventory Management for purchase orders in foreign currencies because of differences in exchange rates between goods receipts and invoice receipts, unless the material can not be debited or credited because it is subject to standard price control.
The transaction keys EIN and EKG (and possibly FRE – see account determination for delivery costs) are only used in company codes where purchase account management is active (as required in France and Belgium for example).
The transaction keys BSV, FRL, and FRN are only used for the Subcontracting item category.
Value string WA14 is defined for deliveries without charge (movement type 511).
The following scenarios are possible:
Delivery without charge for material subject to moving average price control → No accounting document
Delivery without charge for material subject to standard price control (and if the posting date is in the previous period – standard price in the posting period = standard price in the current period) → Inventory posting (receipt at standard price) and offsetting entry to price differences account
Delivery without charge for material subject to standard price control, with posting date in the previous period and the standard price in the posting period is different to the standard price in the current period → Inventory posting (receipt at standard price) and offsetting entry to price differences account (posting in the previous period) → Stock correction posting and Revenue/expense from revaluation (posting in the current period)
In the standard system, value string WA01 is assigned to goods issues and other goods receipts. The R/3 System uses an additional influencing factor, account grouping, to differentiate further between the various movements during account determination.
