There are many database and table-specific reasons why a column or table cannot be inserted or updated. If you attempt to update or insert a row into an Imported table, and an error not related to LANSA is returned, you need to investigate the cause. Validations that the database may perform are not checked by LANSA and so the database may reject the data with a fatal error. Rules should be added to LANSA to perform these checks. If the cause cannot be avoided from within LANSA, you will only be able to read the table. For Imported tables, you may delete a problematic column from the table definition, or mark the table as allowing read access only.
