XL Reporter- Expressions in Parameters.
In XL Reporter for a UDF field we needed to allow users to select multiple options.
E.g. for a UDF field named "Country" which includes a list of countries if the user wants to select all the countries he/ she should be allowed to multi select the names listed.
I have observed from the sample reports that in the Expression attribute of a parameter you can select only the type (e.g. Business Partner )and not the attributes( e.g. Country (UDF field)) of the type.
As a result multi selection is only possible for the type and not the attribute.
