<u>**Issue:**</u>

When trying to import an assay file, the Dispatch_No which is nvarchar(50) in the database (the Maxwell default) gives an error in DataShed due to the buffer only taking in no more than 20 characters.+

<u>**Resolution:**</u>

In the SQL database, go to tblSYSImportMaskField, then Field_Name 'Dispatch_No' and change the Field_Size from 20 to 50 then Save the table.
