-- the content of business document fields is sometimes not correct in the files mapping.log (and map-loader.log)

* mapping.log and map-loader.log don't print the exact content of each business document field, there are several differences:
-the number of characters printed for a business document field is limited.
-VLO business document fields are not printed correctly as they are binary fields
-String business document fields are printed until a NULL character or a \0 character is encountered
