Is there any way to enter a key range in the report writer (other than generating the report from a query)?
Yes, you can use static filters and parameters to set up the range. The report generating logic will analyze the key segment fields against the key fields used in the static filters to see if a reading range can be set up.
Here you can find a complete sample:
Report Writer filter (Start-End) sample (https://manual.pvxplus.com/PXPLUS/Report%20Writer/Generating%20a%20Report/Introduction.htm)
It start creating a StartValue and EndValue parameters (so the user can change/enter them) at run time; them it uses a filter to use StartValue and EndValue as limits of report's data ...
