Calculated field in a join (Report builder)

[make]

Hi Peggers,

i tried to use a calculated field with an iif statement to create a new join in my Report builder, but when i want to make a new fieldpair i cant see this calculated field. In the Report builder Userguide 6-14 i found that its not possible to use this statement i a server evalutable field.

Does anybody have an idea

Thanks for your help
