How to use a relation table to connect 2 fact tables

[Leesanity]

Hi community,

Can someone help me with the question below? 

Now I have 3 tables:

1) Fact table 1: The article expected to be in the store A on 04.06.24 and 05.06.24.

Date	Store	Article
04.06.24	Store A	Article A
04.06.24	Store A	Article B
05.06.24	Store A	Article A
05.06.24	Store A	Article B

2) Fact table 2: The artcle availability in different DC on 04.06.24 and 05.06.24.

Date	DC	Article	Qty
04.06.24	DC A	Article A	1
04.06.24	DC B	Article A	0
04.06.24	DC C	Article A	0
05.06.24	DC A	Article A	1
05.06.24	DC B	Article A	1
05.06.24	DC C	Article A	0
04.06.24	DC A	Article B	0
04.06.24	DC B	Article B	0
04.06.24	DC C	Article B	0
05.06.24	DC A	Article B	0
05.06.24	DC B	Article B	0
05.06.24	DC C	Article B	0

3) Dimension table: Store A can be fulfiled by which DCs

Store	DC
Store A	DC A
Store A	DC B
Store A	DC C

Goal is to have a calculated column named DC availability in fact table 1 based on the info in fact table 2 and dimension table:

The DC availability is the sum of the Qty of Article A among the DCs which can fulfil Store A based on the dimension table (DC A, DC B & DC C in this case).

Date	Store	Article	DC availablity
04.06.24	Store A	Article A	1
04.06.24	Store A	Article B	0
05.06.24	Store A	Article A	2
05.06.24	Store A	Article B	0

Thanks in advanced for your help!

Cheers
