FAQ: How do I import NetSuite columns that lack data in the first 1000 rows?
Create a saved search that filters down to 1000 records
to import the structure. All columns for import require data within the first 1000
records.
A saved search must return at least 1 record of data for each column. For
the best result, populate the entire column and remove nulls. If a filter extracts
at least 1 record in every column that contains data, you can import the
structure.
