Replace table columns without power query

[T_JF2022]

I have a table that shows the sales of a fiscal year, divided into months on the basis of orders. This turnover is then subdivided again on customer groups and overall result.
Now I want to replace a column of this table, let's say february, with values from an additional file, without having to edit the base file in the power query.

i.e. total sales in 12 monthly columns, where 11 months come from file 1 and 1 month from file 2. the whole thing should take place in the visualization.

Hi @T_JF2022 ,

Is there a relationship between the two tables? Please describe your model in details and paste some sample data.

You could use an IF statement I think. So if you have a Calendar / Date table that is connected to both 'Table 1' (from file 1) and 'Table 2' in your data model. In the Calendar table would be a Month column that contains either the name of the month or the month number - whatever you see fit. Then the DAX you could apply to carry out this calculation would be something like:

Total Sales =
IF (
    'Calendar'[Month] = "Feb",
    SUM ( 'Table 2'[Sales] ),
    SUM ( 'Table 1'[Sales] )
)
