Merge Tables Dynamically Using Parameters

[Anonymous]

Hello,

I have 3 tables in the following format and I want to dynamically merge (full outer join) 2 tables at any given time on Fiscal Qtr and Fiscal Month based on paramter that I would like specify in Power BI.

TABLE 1  FORMAT

Fiscal Qtr	Fiscal Month	Data 1	Data 2
FY20Q3	Month 1	Prod A	X
FY20Q3	Month 1	Prod B	Y
FY20Q3	Month 1	Prod C	Z

TABLE 2  FORMAT

Fiscal Qtr	Fiscal Month	Data 1	Data 2
FY20Q3	Month 2	Prod A	X
FY20Q3	Month 2	Prod B	Y
FY20Q3	Month 2	Prod C	Z

TABLE 3  FORMAT

Fiscal Qtr	Fiscal Month	Data 1	Data 2
FY20Q3	Month 3	Prod A	X
FY20Q3	Month 3	Prod B	X
FY20Q3	Month 3	Prod C	Z

The Fiscal Month in the 3 tables are "Month 1", "Month 2" and "Month 3"

I want Power Query to merge on either of following combinations based on user parameters:

 ON Table1. Month 1= Table2. Month 2

 ON Table1. Month 1= Table3. Month 3

 ON Table2. Month 2= Table3. Month 3

How can this be achieved?

You will need to provide some real data per links below. I'm not going to mock something up that misses your goal. That will waste both of our times.

The crux of the matter is though you will dynamically replace the join table names in the Table.NestedJoin() statement, which is easy to do as you are just referring to other tables. I haven't tried this, but I suspect you can even use an if/then/else construct in the table parameters to return the table you want.
