subtraction in set analysis

[Anonymous]

Hi All

In Set Analysis if we use match(LineNo, '1A', '1B', '1C') than all lines value will be added.

Is that possible if I want addition of '1A' & '1B' and subtract '1C' out of these? like '1A' + '1B' - '1C' in single set analysis

Something like this   

Sum({$<LineNo = {'1A', '1B'}-{'1C'}>} AMT)

Thanks

Match is not needed in Set Analysis

How can a LineNo be 1A and IC at the same time? What exactly are you trying to do? Can you elaborate a little?

What exactly do you mean by add and subtract here? Is it set union and set exclusion you mean or the subtracting and adding values?

Basically

Sum({$<LineNo = {'1A', '1B'}>} AMT)  -  Sum({$<LineNo = {'1C'}>} AMT)

in a Single Set Analysis...something like I mentioned in original post

Thanks

AFAIK, this isn't possible.

If I understand you have rows where LineNo have values: 1A, 1B and 1C

If you want a set of lines with values 1A and 1B, just {<LineNo={'1A','1B'}>} but if you want to substract the sum of all lines with values 1C, you need to

Sum({<LineNo={'1A','1B'}>} Value) - Sum({<LineNo={'1C'}>} Value)

You can't put this substaction in one line, in the case you are pointing you have the same result in this case:

{<LineNo={'1A','1B'}>} = {<LineNo={'1A','1B'}-{'1C'}>}

No what you show now is something totally different from what you showed in your original post.

The latter is correct. The original post will do a set exclusion of the rows that are satisfied by the set modifiers... not a subtract of the values.

Satish,

Set Analysis is a simple Boolean condition, it returns True or False for every row of data, and that determines whether the specific row is included or excluded from the calculation.

Besides that, Set Analysis cannot perform any mathematical operations - no additions, no subtractions, no divisions and no multiplications. For these purposes, you still need to use multiple aggregation functions with the corresponding mathematical operators between them.
