Error during merging the text files in Developer t

Hi I am trying to merge the standard NF 2.60 database with Attain3.60. During merging process in the developer tool kit it throws error “A value in the filter '‘CalendarMgmt.CustomizedCalendarExistText(CustomizedCalendar.“Source Type”::Locati’…‘CalendarMgmt.’ in the Name field in the Field/Control table is too long for the field type.Type: Text80” waht may be the cause of this error and how to resolve . regards Sam
