Splitting values where keys matching

[Sergei8000]

I have two tables. In table 1 there is about 800 repeating key values. In table 100 unique key values and 20 columns with data values.

I want output where each matching value splitted by number of matches.

Table 1

id

A

B

A

C

A

A

C

Table 2
unique_id	Col1	Col2	Col3
A	400	100	20
B	200		800
C	600	800

output
id	Col1	Col2	Col3
A	100	25	5
B	200		800
A	100	25	5
C	300	400
A	100	25	5
A	100	25	5
C	300	400

How to achieve this?

hi, @Sergei8000 

try below

Column 1= 
 var a = CALCULATE(SUM('Table 2'[Col1]))
 var b = CALCULATE(COUNT('Table 1'[id]))
  return
  DIVIDE(a,b)

repeat for all column

Hi @Sergei8000 ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create calculated columns.

Col 1 = 
 var a = CALCULATE(SUM('Table 2'[Col1]),FILTER('Table 2','Table 2'[unique_id]=EARLIER('Table 1'[id])))
 var b = COUNTROWS(FILTER('Table 1','Table 1'[id]=EARLIER('Table 1'[id])))
  return
  DIVIDE(a,b)

Col 2 = 
 var a = CALCULATE(SUM('Table 2'[Col2]),FILTER('Table 2','Table 2'[unique_id]=EARLIER('Table 1'[id])))
 var b = COUNTROWS(FILTER('Table 1','Table 1'[id]=EARLIER('Table 1'[id])))
  return
  DIVIDE(a,b)

Col 3 = 
 var a = CALCULATE(SUM('Table 2'[Col3]),FILTER('Table 2','Table 2'[unique_id]=EARLIER('Table 1'[id])))
 var b = COUNTROWS(FILTER('Table 1','Table 1'[id]=EARLIER('Table 1'[id])))
  return
  DIVIDE(a,b)

(3) Then the result is as follows.
