Not able to creat alert over a table chart without removing columns

hi dcadena not sure if you have managed to resolve this issue.

As above, this seems to be a known limitation with data alerts on Table visuals in Power BI Fabric, and you're experiencing it now.

When a Table visual has too many columns (includes non-numeric columns, uses measures mixed with calculated columns), the alert creation UI lets you select a column, but somewhat fails in the background when saving the alert.
My recommendation is to replicate the table into a Card visual (or KPI) using the same measure and then create the alert on the Card instead. Because Card visual is more stable than Table visual. If you want to stick to using Table visuals, then the alternative is to simplify the table (less columns / complexity).

Appreciate if you can 'Kudos' and/or 'Accept as Solution' if this answered your query.
