What causes this issue?

records that the system expects to process. These numbers are not the
same.
Possible reasons for this include:
The foreign key relationship between table &V2& and &V3& is incorrect.
This can happen, for example, if the key fields of table &V3& have not
been mapped completely to table &V2&.

The system stops processing the migration object &V4&.

How to fix this error?

Check the foreign key relationship for the source system table.
If the source system table contains inconsistent data, consider creating
an access plan in order to ignore the inconsistent data.
