can I Perform find based on a external table?
I have a table with information that I want to add to the database. It is possible to find in the database the information of the table?
In the table a field ID exists that also exists in the database.

Sorry my English!

If you've already built a relationship between the two tables, you can simply place fields from the related table on layouts based on the original table. Then you can search on either local or related fields.
