To import a value for a user defined field (UDF), the UDF must be defined in Web TimeSheet. The imported value must match the Type selected for the UDF in Web TimeSheet. For example, if a UDF is configured as a drop-down, the value being imported must match one of the values defined for the drop-down list. If a UDF is configured to be a Date, the value being imported must be a valid date and, if a date range is specified for the UDF, must be within that range.

If a UDF is defined but disabled, any value specified during import will be ignored. Additionally, if a UDF is marked as Required in Web TimeSheet, a value must be specified if the field is being included in the import. If the field is left blank, an error will occur.
