data model dont work

[Pikachu-Power]

Hi all,
I have the following Data Model:

When I filter the Facts 2 table with Segment_F_2 = B it has no influence to the Facts 1 table (Value_F_1 dont change). Does someone has an idea how to solve the problem? I tried to build up a Facts 3 table with primary key and connected with the Facts 1 and Facts 2 table but it didnt work. Then I have the problem that the values in the Facts 1 table dont respect the dates ☹️

Many thanks for ideas.

Hi @Pikachu-Power 

how do you calculate Value_F_1?

Is it measure or calculated column or data source column?

[Pikachu-Power]

It is a data source column.

Hi @Pikachu-Power 

for me it works as appropriated (see example in attach)

The Filtering of the Segments doesn't work yet. If you put a slicer on your canvas with Segment_F_2 = b you filter Facts 2 but not the Facts 1 table. The dates seems to work. I additionally want to filter the Segments. They have in both tables the same meaning.

@Pikachu-Power 

it's correct behaviour because power bi knows only about Date relationships.

do you want to use both relationships by Date and Scenario at the same time?

[Pikachu-Power]

yes at the end i will compare the values in a table. if i filter the segment the values should have the same dates and the same segment 😕 i dont want to use a separate segment filter for table Facts 1. that should passoible or?

@Pikachu-Power 

should it work in both directions?

Segment_F_1 should filter fact 2 table?

[Pikachu-Power]

No in just one direction at the moment. Segment_F_2 should filter Facts 1. But maybe it is possible with a Facts 3 table that connects the segments? Maybe i should try it again.

@Pikachu-Power 

my idea is to create surrogatekyes calculated columns in both of Fact tables 

SurrogateKey_1 = CONCATENATE(FORMAT([Date F 1], "YYYYMMDD"), [Segment F 1])

AND

SurrogateKey_2 = CONCATENATE(FORMAT([Date F 2], "YYYYMMDD"), [Segment F 2])

then delete relationships with calender table and create relationships SurrogateKey_1 - SurrogateKey_2

your solution seems to work. many thanks for your effort 🙂

i have now again false values but the reason is an another one i thinks.

thats great, good luck!

[Pikachu-Power]

It didnt work. Is it maybe with a measure possible? 😪
