two columns from two table has one to many relation, how can I combine them into a single table? I want to make a null or 0 if there is mismatch

Hi, I am not sure how your semantic model looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file whether it suits your requirement.

It is for creating a new table.

expected result table = SUMMARIZE( 'Sales', 'Customer'[customer key], 'Sales'[shop], 'Sales'[quantity], 'Customer'[customer name] )

Hi, thanks for helping. when I tried this on my file, it will not let me pick the second table.

for example, once I have 'Table 1' after summarize, I can not have 'Taable 2' [Column 1]

Hi, thank you for your message, and I think it is related to the relationship issue.

Please share your sample pbix file and then I can try to look into it.

thanks.

Hi Anonymous ,

From your description,
I think you could try joining the two tables together using a merge query.
My Sample:
Table1:

Table2:

The operation is shown below:

In Power Query Editor, select Merge queries.

Then choose to expand the fields in the new table column.

Result is as below.

If you want to know more about the Merge queries, you can refer to the following link.
