NSC | Why NetSuite CSV Imports Only Show One Error at a Time

Ivy Lopez-Oracle

Scenario

A company uses CSV Imports for large-scale updates involving thousands of records. During testing, the import fails, but NetSuite only displays one error at a time. After fixing that error and rerunning the import, another issue appears. This makes it difficult to identify and correct all problems in one pass.

Explanation

This is standard NetSuite behavior. CSV Imports stop at the first error found, so only one issue is shown at a time. Also note that, when multi-threading is not enabled, NetSuite processes the file left to right, top to bottom and stops when it encounters the first error.

The ability to show all CSV import errors at once is currently a system limitation and is tracked as an enhancement request:

Enhancement # 485337

CSV Import > Error > Show all errors, instead of just the first one

Best Practices

• Use Internal IDs whenever possible to reduce matching errors during CSV import.
• Use Internal IDs for sublist data as well, especially when updating line-level records.
• Test smaller sample files first to make troubleshooting easier before running large imports.
• Review field mapping carefully before each import run to reduce repeated failures.
