How To Fix DO121 - No conversion necessary in dependent tables

DO121 - Overview

• Message type: E = Error

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

• Message number: 121

• Message text: No conversion necessary in dependent tables

What causes this issue?

The current change to the domain does not cause a conversion
(activation and adjustment on the database) for dependent tables or the
domain is not used in tables or the domain was not changed.
The following changes to a domain can cause a conversion for dependent
tables:
- data type
- number of places
- number of decimal places.
Dependent tables are the tables which contain a field to which the
domain is assigned. The database system on which it is based, the
attributes of the corresponding table field and whether the table
contains data on the database determine whether the change results in a
conversion.
