Hi @avinashlumos,
Interesting that nothing is showing up at all; you said you’re using custom aggregation methods, what do those look like? Certain aggregations may stop the system from being able to run totals so it may be dependent on the fields and aggregation being used. Any additional information you can share could be helpful as it doesn’t seem to be an issue from something not being selected.
Ideally, if you’re able to upload a sample copy of your analysis with anonymized data, to QuickSight Arena, that would most likely be the easiest way for us to assist further!
