Suggestions:

Also when Freight account code was not available in item acct Determination. It is observed sometimes that users enter the freight amount and select the freight account. On confirmation of the receipt system checks the freight account mapping with the item series and system shows the message ‘Account Code Not found’.
Remedies:
This will require support from the Proteus support team or its partners
If an advance to be given to the supplier then Advance A/C code should be defined in supplier master.
Sometimes all the account codes are mapped properly however if the freight is entered then the freight account which the user selects should also be mapped in Item account determination.
Once the account mapping and defining is done for the item series used then the user can confirm the Purchase receipt. To check freight account user should go to Finance Menu -> Masters-> Item Account Determination
