I have some data where I would like to create a query that will perform 2 separate calculations based on the group id in tableau
Here is my data
id total avail
A 10 5
A 40 20
B 20 10
B 10 5
B 10 5
A 20 10
A 20 10
B 10 5
B 10 5
I wish to group all the 'A' ids and sum them (Group1) and I wish to group all the 'B' ids and Average them. (Group2)
This is what I am doing:
first group the IDs:
IF [Id] = 'A' THEN 'Group1'
ELSEIF [Id] = 'B' THEN 'Group2'
ELSE 'none'
END
Now perform calculation:
IF ATTR([group]) = 'Group1' THEN SUM('A') ELSEIF
ATTR([group]) = 'Group2' THEN SUM(['B'])/SUM(['B']) ELSE 0
END
However, this is not correct. I am still researching this. Any suggestion is appreciated.
One suggestion here- Create groups in Tableau (by right clicking the field instead of having these through calculations).
I am giving solution on the basis on previous sampled data.
data sample used-

make a new calculated field desired new val
as
zn(sum(if [Sku (group)]= 'sum group' then [val] end))
+
zn(avg(if [Sku (group)] = 'avg group' then [val] end))
last step build your view as
PS for adding tooltip you need not keep 'total' column. It can be added anyways.
