How To Fix DO120 - Changes can cause dependent tables to be updated

DO120 - Overview

• Message type: E = Error

• Message class: DO - Dictionary: Mass activation of domains and data elements

• Message number: 120

• Message text: Changes can cause dependent tables to be updated

What causes this issue?

One of the following attributes of a domain was changed:
- data type
- number of places
- number of decimal places.
This change can cause a conversion, i.e. activation and adjustment on
the database, for dependent tables (transparent, pooled or cluster).
Dependent tables are the tables which a field to which the domain is
assigned contains. The database system on which it is based, the
attributes of the corresponding table field and whether or not the
table on the database contains data determine whether or not the change
will result in a conversion.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you really want to make the change, it is best if you make sure that
the dependents are converted in mass processing if there is
a large number and for large, dependent tables . You can enter these
tables using the database utility (menu Utilities -> Database utility)
for mass processing. The activation log of the domain specifies which
tables have to be converted.
