Why user and record type lookups are not filled on insert?
Question:
I'm importing data from a CSV source into a custom object with a custom Lookup field to the User object, but the field isn't being filled when inserting new records. Why is this happening?
Answer:
The issue might be due to missing RecordType.csv and/or UserAndGroup.csv source files.
For successful import of lookup values, it's essential to provide ALL CSV source files, as the Plugin treats these files like a "virtual" Salesforce org containing all necessary records.
