adding columns whose values are also based on scaling values in different table

alex779 — Wed, 24 Jan 2024 21:47:30 GMT

Hello there!

Have 2 tables (PVprod and StrutturaCER). I need to add new columns named "Pn" (n=1,2,...) to first table PVprod.
Pn = reference column IRR * a scaling coefficient PVnew[n] taken from column PVnew of the second table "StrutturaCER", where n is the row index of PVnew (see pics below)

Is this at all possible in P.Bi ?

I'd like to get as many new colums added to table PVprod for all values of PVnew (including zero values).

Any idea / suggestion in DAX?

Thanks a lot, Alex

Hi, alex779

Based on the information you have provided, I created two tables, Table1 and Table2.

Then New Column, multiply ScalingFactor of Table2 and Value1 of Table1 to get a new column.

Column = Table1[Value1] * RELATED(Table2[ScalingFactor])

This enables calculations across tables, so if you want to do more with your table, provide me with more data.

M Code

=Table.FromRecords(Table.TransformRows(PVprod,each Record.TransformFields(_,List.Transform(List.Position(StrutturaCER[PVnew]),(r)=>{"P"&Text.From(r),(x)=>[IRR]*StrutturaCER[PVnew]{r}}),2)))

thank you but my tables are NOT of the same size.. So it does not work for me.
My Table1 is like 9000 rows and Table2 (scalingfactors) only 10 rows. I had to rescale each of the 9000 cells IRR in a new column with scaling factors taken from Table2, and add as many columns as the 10 scaling factors..

Hi, thanks but getting this error. Seems a "ciclic error during evaluation"

it's not a formula in Custom Column

it's a whole step code, try to delete Table.AddColumn outside
