Hi @hrryln
Apologies for the delayed response!
Please check that you are not exceeding any row or size limits, especially for joins across data sources or with large datasets.
Verify that column data types and values are an exact match, as errors often result from type mismatches or null values.
If you want to join across different data sources, the result must be a SPICE dataset.
Please refer to the below Quick Suite documentations and community post this might be helpful for you.
