2.What process triggers the transaction key BSV? what type of account should be assigned here ? Hw different is it from GBB-VBO ?

3. What is the difference between DIF , PRD & UMB ?

1) AUM is triggered if the material iin supplying planrt is maintained either in MAP or Standard price and material in recieving plant is in stamdard price and there should be a price difference.The differencial amount will be posted to the Expense/Income account through AUM

2)BSV will be triggered during subcontracting is the Transaction event key which defines the Change in stock account .This is maintained to accomodate the credit side entry for the output material during GR.Whereas GBB-VBO is for input material consumtion during subcontracting GR.It provides the Debit side entry for Input material consumption

3)DIF is triggered during IV if there is balance and you still want to post it

PRD is triggered if the material is maintained as Standard Price and the value is differenet from the PO value .

UMB is triggered if you want to revaluate the material th MR21

4) GBB-VKA is for make to order scenario where you make a PO directly with reference to sales order
