Acc assignment vs determination

Question

hi,
1) acc assignment - can be in anywhere of various modules, fi, co, mm, fd. during data entry, we need to MANUALLY put in the gl account in acc assignment fields. right?
2) acc determination - define in obyc or vkoa. this will let the system to determine which transaction code like bsx, wrx to use depends on which business process. this is more to BACKEND defined as compare to account assignment. right?
3) what is the main difference of assignment and determination? can i say assignment only single gl account whereas determination will be the double entry.
hope to have clarification.
thanks

Answer 1

hi,
point given to all.
clarify the following reply.
in acct determination too you can single entry for acct determination if you dont select in the rules debit or credit.
1)what does it mean do not select in the rules debit or credit?
2) in obyc or vkoa i notice some without gl account but some with gl account. what does it mean?
In a sales transaction the cutomer is debited and the revenue account is credited. Here the sales account is determined via VKOA, as you rightly said. This is becuse of 'account determination'. However, only one of the entry is determined, the corresponding debit entry, namely customer account is not known until you do the sale.
We cannot classify strictly that 'Account Determination' will provide all theG/L accounts for the completion of journal entry. The other way is true.
3)  how the system determine the sales account? i mean how can system know which sales acc to credit? do we need to enter any thing so system will know which sales account to use? any example?
4) 'the other way is true' - what does it mean?
thanks
