You could use the "Alter table" statement to modify existing tables and create table to add any new tables.

See, http://dcx.sap.com/index.html#sa160/en/uladmin/ul-alter-table-statement.html

You do need to detect whether a schema change needs to applied by querying the syscolumn and systable tables. http://dcx.sap.com/index.html#sa160/en/uladmin/fo-db-internals-s-3513569-java.html
