If you’re using Email Studio in Salesforce Marketing Cloud and receive an ‘Error: updating filter’ message when creating a new Data Extension, it’s likely because the name you’ve chosen already exists.
This error message can be misleading, but a simple solution is to rename the Data Extension with a more unique identifier. Make sure to double-check for any additional spaces or formatting issues that may be causing the error. Refer to Salesforce’s documentation for more information on troubleshooting Data Extension errors.
