VKOA Account determination

Question

Hi,
In VKOA I see different tables and I am not understanding how the system will pick exact table for determiniting the account.
Example:
In VKOA I have as follows
001 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Acc Key (say ERL)
002 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Item category (XXX1) / Acc Key (say ERL)
003 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Item category (XXX1) / Order reason (001) Acc Key (say ERL)
Question
In this case if I post how will the system search for account determintaion if I post invoice which has
1) Cust Acc Assign (A1) / Mat Acc Assign (M1) / Item category (XXX1) / Order reason (001) Acc Key (say ERL)  ?
2) Cust Acc Assign (A1) / Mat Acc Assign (M1) / Acc Key (say ERL) ?
I would like to know the order in which system will look........is it like first it checks 001 if not found then for 002 and if still not found in 003?...Am I right?
In my question 1, system finds both Cust Acc Assign (A1) / Mat Acc Assign (M1) in invoice and system may fetch account from ERL assigned in 001 - but I want system to take 003.

Answer 1

Your understanding of system behaviour abt account determination is corret. To resolve your problem you need to change sequences from most specifice to the most general.
In your case it should be like
003 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Item category (XXX1) / Order reason (001) Acc Key (say ERL)
002 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Item category (XXX1) / Acc Key (say ERL)
001 - Cust Acc Assign (A1) / Mat Acc Assign (M1) / Acc Key (say ERL)
Hope this will resolve your problem
