Sorry for the previous post. Found the solution: It is possible to nest subreports, you just have to specify the SUBREPORT_DIR as paramter for all subreports and pass them in as subreport param from the mother report. Maybe this also helps someone ;)
Hi, I have a subreport which has a subreport inside, and here I get "could not load object from location .". If I delete the subreport in the subreport and specify the SUBREPORT_DIR everything work fine. Thanks in advance for your help. Chris
