Message
The following string field values were truncated because they contain values that exceed the maximum length: <fields>
Description
The string values being written exceed the maximum length for the fields specified in the message. The values will be truncated to the maximum length supported by the field.
Solution
When creating feature layers or tables using Data Pipelines, the default length of output string fields is 4000 characters. To create string fields of a different maximum length, use the parameter String field length in the output feature layer tool.
Feature layers and tables created outside of Data Pipelines may contain string fields with other character limits. To verify the maximum field length set for a field, go to the Data tab of the feature layer or table item page, switch to the Fields view, and inspect the length value for the field of interest.
