How to create calculation as a percentage of a row value

Question

How do I create this calculation in OBIEE? It seems simple but I can't get the right results.
Let's say I have a field called Account with the following values:
Sales - 1000
Product Cost - 300
Operating Supplies - 100
Returns - 100
Fixed Costs - 300
I need to create a column that would be percentage of Sales. So my report would now show:
Sales - 100%
Product Cost - 30%
Operating Supplies - 10%
Returns - 10%
Fixed Costs - 30%
How do I do this? It's very easy for me to create a percentage of total calculation, but I can't create a percentage of a specific row.

Answer 1

Hi,
Sales, Product Cost, etc are row values for Accountthis is where your complexity come in.
if those are individual measure labels then it would've been easy to achieve.
But, still can do one thing.
report split into two views: one will show normal values, other will be % side by side in compound layout.
1. create those many columns in criteria using filter() function, and name it as Sales, Product Cost
ex: for Product Cost heading column fx will b: 100*filter(Amount using Account = 'Product Cost')/filter(Amount using Account = 'Product Cost')
2. now, in pivot 2-> use each column as measures and add those many into measures part of pivot.
3. Drag Measure Labels to Rows part.
4. Add both the views to compound layout side by side.
(i'm assuming that we need to show actual and % values in report, if not you need not to go for pivot1, simply one pivot with above logic)
but it has got limitation like: if Account column is populated with one more value tomorrow.. it'll be a problem..
