Hi All

Hi ,

It will be great if you provide optimize dax as per above query it will be helpful to understand that

Hi @aamirkhan_WT ,

Please refer to the following blogs to optimize your DAX formulas:

Improve Power BI Performance by Optimizing your DAX

How to make your Power BI reports faster:To optimize DAX queries

It's a little difficult to give you a suitable solution without some sample data and backend scenario(function). Could you please provide some sample in the involved tables('wt_fin_staging_pl_accounts_mapping_sorting' and 'wt_fin_staging_pl_accounts_mapping_sorting') and the functions which your above formula want to achieve? It is better if you can provide some special example to explain your expected result. Thank you.

Best Regards

@aamirkhan_WT , Try calculation groups or field parameters.

I am really not sure, why need so many formulae here.
