Remarks on Changing Domains

You will find information below on what you need to bear in mind when changing entries in the domain maintenance screen. The significance of all other information shown on this screen is explained in Creating Domains.

When changing existing domains, remember that this affects all tables containing a field referring to the domain in question. Foreign keys could become inconsistent in the affected tables. A conversion of this table could be necessary (see Adjusting Database Structures). This could be very time-consuming for tables containing a large number of records. Therefore, before changing a domain, you should find out about the effects of this change by selecting Utilities ® Where-used list.

Changing the Data Type and Number of Places

You can change the data type and number of places or decimal places simply by overwriting the relevant data. Note that a change of this type can cause all tables containing a field referring to this domain to be converted.

Changing the Value Table

If you remove or change the value table, the foreign keys that are affected are retained. The activation log lists all the foreign keys that are affected by the change to the value table. You can delete or adjust these foreign keys as required.
