Self-lookups are not supported during data migration. A self-lookup is a field on an object that references another record on the same object — for example, a child category that references a parent category. During import, the DPE cannot automatically create hierarchical relationships between records within the same object. After the import completes, establish these relationships separately using Apex logic, Data Loader, or a Flow. The following self-lookup relationships are not created during import:

Object	Scenario
Ad Target Category	A child category referencing a parent category
Ad Target Category Segment	A child segment referencing a parent segment
Ad Target Segment Value	A child value referencing a parent value

Review the following limits before importing data. Exceeding these limits results in job failure.

Guardrail	Limit	Applies To
Maximum records processed via DML	10,000	Both templates
Maximum records queried via SOQL	50,000	Both templates
Maximum CSV file size	12 MB (varies based on heap size)	Both templates
Maximum new records per row	3	Both templates
Total records in source objects (Ad Target Category, Ad Target Category Segment, Ad Target Segment Value, Product2, Product Classification)	50,000	AssignTargetingDataCSVTemplate.csv
