Ap Freight Line Allocation

Hi ,

We have an Issue with the way Freight Line Allocation and corresponding distribution is generated.

We have an Invoice with Invoice amount ( total amount including the tax amount ) . Then we add Invoice lines with ITEM type and Freight . ITEM line is PO matched and so distribution, Purchasing Category and Ship to is derived from PO. On the Freight Line after we enter the amount , we click on allocate(prorate across all item ) , when we click to see distribution against Freight Line , we get a error message like 'APP-SQLAP-97734: The system cannot generate distributions for line 2 because: The sum of the line amounts does not equal the invoice
