Hi,
I have been trying to find a way to have an attribute in an Entity that will
show me a percentage value. Example: you have an Entity "Expenses" that has
attributes for "Expense Name", "Expense Amount", and "Percentage of total"
Expenses". Where "Percentage of total" gives you the percentage the "Expense
amount is of the total expenses. Is there an easy or not so easy way to do
this. Have tried the @sum operator, fetch requests, etc. Seems like there
should be a simple solution. Have searched the mail list but could not find
anything. Any suggestions would be appreciated.
Scott.
