How to summarize during many-to-many relationships

[Anonymous]

Hello.
I want to make a table that summarizes table1 and table4 below.

But table4 is not displayed. . I also couldn't use the RELATED function.
table1-table2 is related with key1 and table2-3-4 is related with key2.
I want to know the solution.

Hi @Anonymous ,

Has this relationship ever been tried?

Table = 
SUMMARIZE (
    Table1,
    Table1[key1],
    Table2[key2],
    "V1", SUM ( Table1[value] ),
    "V2", SUM ( Table4[value2] )
)

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
Best Regards,
Winniz

@Anonymous you should be able to achieve what you are wanting in Power Query and use the Group By function:

Hope this helps! 🙂
