Find a specific row of a one-to-many relationship and return a value

Hello everyone

Very new in Power BI (e tbh reports).

I have two tables in a one-to-many relationship where the parent's "registration ID" is the key to the related child records. Each row in the parent table relates to many rows in the child table.

I'm trying to create a report in which I need to extract a specific child record based on a column and then return another column from the same row.

Sample tables:

Table 1 - Parent Table

Registration IDNumber
1234Already
5678Tina

Table 2 - children's table

Parent linkNumberValue
1234date_112/03/2010
1234date_205/05/2012
1234text_1Test text here
1234text_2Some how things test here
5678date_129/08/2009
5678date_211/12/2020
5678text_1More test placeholder material
5678text_2testing 123

What I need in the report:

For each record in Table 1 I need to add a column "Date 1" and "Date 2" and fill it with the "value" field in Table 2 where "Date 1" is the secondary record related to Name "date_1" and "Date 2" is the secondary record related to Name "date_2".

Example of output:

NumberDate 1Date 2
Already12/03/2010

05/05/2012

Tina29/08/2009

11/12/2020

Any guidance on how I can do this would be greatly appreciated. Thank you!

Amazing

 

 

Thank you so much, and thanks for the quick response!

Just for the record I had to replace ";" with "," for it to work, but other than that this is exactly what I needed. You're the best.
