Impacting the Schema

On the UET Impact Schema form, select Commit Form Changes to save the changes you have made to the form information using the UET forms.
Select Impact Schema to change the database schema to contain the columns and indexes corresponding to the user fields you have defined in the UET forms. Corresponding views over multi-site tables are also updated.
Click Process.

If your system is multi-site and the table where you add the UET, or the corresponding _all table, is replicating data, there are additional steps you must take. The Replication Reference Guide contains a chapter on "Setting Up Custom Replication." In it you can find information about copying table schema changes to other sites.
