Hi @Shreyash and welcome to the community!
As this is a public user forum we don’t have access to specific dates for new features, but I think there might be a couple workarounds to the “No Data” message text on visuals.:
Try using a Insight (narrative) visual with an ifelse statement that checks whether data exists. If the result is null/empty, display your custom business-friendly message instead. This community post walks through the approach.
Another potential route is to create a conditional “overlay” visual, essentially a text or free-form visual that displays your custom message and is configured to only appear when the underlying dataset returns no rows. You can do this in a free-form layout by stacking a custom message visual on top of your data visual and using hide and show logic so it only shows when a calculated field like countOver([], []) =zero. It’s not as clean as a native setting, but it does give your end users a business-friendly message instead of the generic one.
Hope this helps and feel free to reply with any updates/questions you have regarding this topic!
