These functions allow you to copy the filters of a single field or all the filters on a record (table) and apply those filters to another record. Their syntax is as follows:
FromRecord.COPYFILTER(FromField, ToRecord.ToField)
The From and To fields must be of the same data type. The From and To tables do not have to be of the same format:
ToRecord.COPYFILTERS(FromRecord)
Note that the COPYFILTER field-based function begins with the FromRecord variable, while the COPYFILTERS record-based function begins with the ToRecord variable. ToRecord and FromRecord must be different instances of the same table.
