Merge Tables Dynamically Using Parameters

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     
FY20Q3Month 1Prod AX
FY20Q3Month 1Prod BY
FY20Q3Month 1Prod CZ

 

TABLE 2  FORMAT

Fiscal Qtr     Fiscal Month       Data 1       Data 2     
FY20Q3Month 2Prod AX
FY20Q3Month 2Prod BY
FY20Q3Month 2Prod CZ

 

TABLE 3  FORMAT

Fiscal Qtr     Fiscal Month       Data 1       Data 2     
FY20Q3Month 3Prod AX
FY20Q3Month 3Prod BX
FY20Q3Month 3Prod CZ

 

 

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.
