Virtual Table

Dear all,

 

I've a table where the values are overwrited every month so I lose the historyc.

I've created a virtual table as follows:

godtooro_0-1689236400453.png

 

Where:

  • Barcode = Product iD
  • BARSTDR = Standard cost
  • BARMFEC = Date of the Standard cost

As the original table is overwrited everymonth I want a virtual table to storage this information month by month.

Do you think that the virtual table with SUMMARIZECOLUMNS is going to lose the information every month with the last one or on the contrary is going to keep it register by register monthly?

Do you know how I can create a virtual table that don´t lose the information?

@godtooro  ,Are you using incremental refresh on your table ?

If not then it is not possible , Power BI is a "read only" system so it doesn't have the ability to store data beyond a refresh. 

 

You will either have to modify the source system (you said not an option), or put in an intermediate process in place to store a previous day snapshot of data, then have Power BI read in the source data and the snapshot, then do the comparison.
Thanks,

Hi @godtooro ,
