This article applies to DeltaWMS version 20.32 only. If you are running a later version, this issue does not affect you.
A bug has been identified in DeltaWMS v20.32 that causes CSV exports to fail or produce incomplete/corrupted output under certain conditions. We recommend upgrading to a later version to resolve this issue permanently.
What is the issue?
In DeltaWMS v20.32, users attempting to export data to CSV may experience one or more of the following symptoms:
The CSV export completes but the resulting file is empty or missing rows
Special characters or line breaks in field values cause rows to split incorrectly
The export process fails silently with no error message displayed
Column headers are present but data rows are not written to the file
Which exports are affected?
The bug can affect any CSV export initiated from within DeltaWMS v20.32. Commonly affected areas include stock reports, order exports, and adjustment exports.
Root cause
The issue is caused by a defect introduced in v20.32 in the way the export engine handles text encoding and field delimiters. Fields containing certain characters (such as commas, line breaks, or extended Unicode characters) are not correctly escaped, resulting in malformed CSV output. This defect was not present in earlier versions and has been resolved in the versions that follow v20.32.
Recommended solution: upgrade DeltaWMS
The only permanent fix for this issue is to upgrade DeltaWMS beyond v20.32. The export defect has been corrected in subsequent releases. We strongly recommend upgrading to the latest available version to benefit from this fix and all other improvements and security patches included in later releases.
To upgrade DeltaWMS, please contact your system administrator or reach out to our support team, who can guide you through the upgrade process.
Workaround (if you cannot upgrade immediately)
If upgrading immediately is not possible, you can reduce the impact of this bug by:
Avoiding data fields that contain commas, quotation marks, or line breaks where possible before exporting
Manually reviewing exported CSV files to check for missing or split rows before using the data downstream
Exporting smaller data sets to reduce the risk of the issue occurring
These workarounds are temporary measures only. They do not fully eliminate the risk of data loss or corruption in the export. Upgrading remains the recommended and supported resolution.
