If you want to override the database and schema in the advanced properties for source objects, the database and schema selected in all the source objects must be the same.
For example, a mapping contains the following objects:
object1:
<db1>.<schema1.<object1>
object2:
<db1>.<schema1.object2>
For example, the following image shows the two source objects used in the mapping where the database and schema name for both the sources are the same:
If the database and schema are different, for example, if the database and schema for object1 is
<db1>.<schema1.object1>
and object2 is
<db2>.<schema2.object2>
, migration does not work.
When the mapping contains multiple objects, do not override the table from the advanced properties.
