Difference between Webi Formula and variable
I thought to write something which is not covered yet in Google. Lately, while working on a report where one formula is used multiple times an interview question pops up in my mind that what is the difference between formula and variable.
Benefit of variable:
Easy to understand & recognize.
Change is at one place and reflects everywhere in the report.
Maintenance efforts are less in case of future change.
Variable is manadatory to create detail variable.
Indeed; a variable can simply be a value, such as:
A formula will usually contain some kind of operator or function.
i agree Neil Mitchell
Formula once create only Work one Place. formula Not Reusable.
Variable once create u can can use Multiple places.
Just wanted to know like Crystal I don't think we have anything like local global or shared variable that we can refer.
So how can we call it as a Variable in Webi because like what Niel said if we say =30 is a formula although its an constant.
Please clarify me on this regards.
