Infoset Query - Coding
I have a requirement to be able to produce a fairly complex query but prefereably using infoset queires rather than a BW query.
Is it possible in the coding section of an infoset query to call function modules?
If so do they have to conform to a certain interface?
If this is not possible does anyone know of any internet sources of good coding examples?
The reason for the infoset query is that in CRM these can be used as Attribute Lists to build target groups in segmentation for marketing campaigns.
