Create new table and insert values automatically based on condition

[Anonymous]

Hi all, not sure if  this is can be done in Power BI. Hope someone can give me some suggestions: 

I have a table below where the Current_Debt and Old_Debt are changed time to time, this table was refreshed every monday in my powerBI desktop. 

Account_number	Current_Debt	Old_debt
1001	0	12
1002	28.34	234
1003	296.7	0
1004	654	6
1005	0	8
1006	77	9
1007	0	0

Also, I want to create a table called weekly_change,  so when the table above refreshes, it will automatilcly sum the current_debt where current_debt is not 0 and also count of account number, and sum of Old_debt, then insert the table weekly_change, the date value would be the time when we refresh the table.

Weekly_change 

Date	Account_number	Current_debt_sum	Old_debt_sum
30/04/2021	3	979.04	246
3/05/2021

 Would it be possible to do that in power query? 

Thanks so much

Hi @Anonymous ，

Will the weekly data be saved in the table or will the data in the table be directly updated when a new date is reached? In addition, is there any date column to indicate which date the data belongs to? What is the calculation logic of the table you want to get in the end? Is it a summary value(0+28.34+296.7+654+...)?

Best Regards
