TIBCO Spotfire-插入计算的行

Question

I'm trying to insert rows to the table in Spotfire that are a sum of existing rows

Existing Table:

ID  SUB_ID  Line  Quarter  Value   
1   123     A     1        1  
1   123     A     2        2  
1   123     B     1        3  
1   123     B     2        4  
1   124     A     1        5  
1   124     A     2        6  
1   124     B     1        7  
1   124     B     2        8  
2   123     A     1        9  
2   123     A     2        1  
2   123     B     1        2  
2   123     B     2        3  
2   124     A     1        4  
2   124     A     2        5  
2   124     B     1        6  
2   124     B     2        7  

Rows to Add:

ID  SUB_ID  Line  Quarter  Value (sum)
1   123     A     2        3  
1   123     B     2        7  
1   124     A     2        11  
1   124     B     2        15  
2   123     A     2        10  
2   123     B     2        5  
2   124     A     2        9  
2   124     B     2        13  

What is the best way to do this?

Answer 1

the steps to implement the suggestion Monte_fisto made are outlined in another answer . make sure that you add the column as a transformation (Insert>Transformations...) rather than as a calculated column or you won't be able to use it as an index for the join.

another potential solution is to insert a calculated column with an expression like:

Sum([Value]) OVER Intersect([ID], [SUB_ID], [Line])

and then having your visualization measure that column.

it really depends on what you're going to do with your new data. if you provide some more detail I'll try to answer more specifically.

Answer 2

You can also create a pivoted derived table if you want to preserve your original table. Otherwise, just add a pivoted tranformation (insert > transformation)
