Diagnosis
You have attempted to create or update a sales or purchasing document. In the Contents tab, you have added a service row with freight charges, but the price is not defined. Therefore, SAP Business One cannot calculate the freight charges.
Procedure
In the Contents tab of the sales or purchasing document, in the service row with freight charges, specify values in the Unit Price and Total (LC) fields.
