Error in new column using lookup value

Hi  Nowherefast74 ,

This error may be due to the remote server being unable to handle concurrent processing of multiple tables. You can try the following:”

Is your Power BI Desktop the latest version, if not, you can update to the latest version.

Download Power BI Desktop from Official Microsoft Download Center

Adjust parallel loading of tables settings：
File – options and settings – options – current file – data load.

Prevents multiple queries from being executed at the same time, thus allowing one query to be processed at a time to ensure a successful report refresh. However, this may result in longer refresh times compared to parallel processing. Alternatively, the user can select the "Custom" option and try the optimal number of tables for concurrent processing.
