SAP Error Message - Details

• Message type: E = Error

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

• Message number: 342

• Message text: No conversion necessary in dependent tables

What causes this issue?

The current change in the data element does not cause a conversion
(activation and adjustment on the database) for dependent tables or the
data element is not used in tables or the data element was not changed.
The following changes to a data element can cause a conversion for
dependent tables:
Specification of another domain for the data element, where one of
the attributes of the old and the new domains are different:
data type
number of places
number of decimal places.
Dependent tables are the tables containing a field to which the data
element is assigned. The database system, the attributes of the
corresponding table field and whether or not the table contains data on
the database determine whether the change will cause a conversion.
