There is a report. Depending on the condition, it can be based either on one sample or on the other, or both samples should be combined. The number of fields is identical, the difference is only in the data source. Report built in fast report. In c #, the request is executed and xml, and xsd files are thrown in fastreport.
How do I implement, depending on the condition, that the report be built on different samples and both together? In fastreport already created 2 data sources. What to do next until I can not understand.
