Need Help on dealing historical data in Power Bi

[Heena_9980400]

Hi Experts,

I am working on a project where I am dealing with 10 years of historical data(there is no live data) and the reports are ad-hoc reports we are not using any measures or logic(just keeping data in a table visual with 1 filter) and how power bi will handle that huge amount of data, is there any tricks to deal with it, kindly help me on this and do the needful.

To manage a large amount of data you could flow these guidelines:

1. Remove all unused columns from your data table.
2. You used a slicer in the report so that I could consider you could maintain fact and dimension tables in the data model.  
3. If possible, summarize your data. For Example, If you did some calculations in the visual like summation, count and so on do it in the backend (Power Query or SQL Query or anywhere) it will reduce lots of records and make your report lighter and faster.

If you think this idea will help you to manage your large dataset.

Then please accept the answer.

Hi @Heena_9980400 ,

You could start of with the use case.. If the business objective is to identify sales trend for the past 10 years. 
Then you could reduce the granularity of your data by  having  1 fact table (Sales Data) and multiple dimension tables related to the fact table. (Dimension table depends on the user requirements/ asking the user).
