Can we define a parameter to be mandatory so that user needs to enter some value for it in Oracle BI Publisher 10g? If yes, how do we do that?
We had the same issue days before. It seems that BI publisher do not support such kind of constraint on parameters. To solve this issue, we had to connect to BI publisher using its web services, get the report parameters and import the report into our application. Using this way, we managed to set any kind of constraint on parameters.
