Creating new series-Do we need a database colum for if it can be displayed by Expressions?
Hi All,
We are creating many new custom series ( 15 Qty and 15 Amount ). These are quanties, unit cost and Amount ( Amount =Qty * Unit Cost).
My question is for the Series (Amount) ..
1) Do we need to provide a update Database 'coumn' or this can be left blank and derived with a server expression ?
2) Currently I have not defined a dabase column..so system does not create a column in the SALES_DATA. Are there any problems with this approach ?
3) Do we need to perform database tuning once we creating these 30+ new series?
One of the problem I am seeing is difficulty in writing the server expression.- If we store the data in a database column, writing server expressions is easy. If we do not store the series to a database column, writing expressions is more complicated.
