Account assignment for Movt type 101 and 501

Question

All SAP Gurus,
We want to do the account assignment for movt types 101, 102, 122, 123, 201, 202, 261, 262 accourding to the movement types.
We are aware that the Transaction Key is 'GBB'.
But how to know that which 'General Modification' is used for which movement types.
(in short where we can find this link between movement types and Transaction Key and 'General Modification')
Regards,

Answer 1

To know this first you have to know what does the different general modifications means for GBB:
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
Then go and check OMWN.
