>>If anyone has dealt with foreign keys in FPW 2.6 you probably already know my question. I have a tag on a table whose key is set to a related table. (I do this for display ordering and filtering) If the field is changed or modified, such as City being chaged from 'New York' to 'Los Angeles', the foreign tag in the other table will no longer be able to do an optimized locate or filter for that record. It simply gets skipped because the data has changed. I have a work around right now that when the contents are changed it deletes the record and then does a SQL INSERT. That works fine, but is there a more effective way to keep the foreign tag updated?

The field can be edited from several different applications. It's in a parent or entity table.
