Hi Andre,
Thanks for you reply,
Sorry for my little information
i have created transaction from POS which contains returns and sales then i back to ax to calculate and post statement then the error appear.
i saw the item model group "receiving requirements" is checked when i remove the check statement posted successfully but we are using this parameter to enforce the user to make product receipt(Packing Slip) before invoice.
but when i clear the check user can make invoice without product receipt.
Kindly advice.
