If you want to recreate the exact Private DS Tables, relationships, etc. for the sake of the report you may need to do it all in Session Code;

Define Class MyreportDS As Session
 Proc Init()
  Open abc IN 0 Shared
  Open def in 0 Shared
  Set Relation to CustNo into abc
  etc. etc...
  .....
  Report Form Blah-Blah Preview
 EndProc

 Proc Destroy()
  Close All
 EndProc
EndDefine

This DS can be attached to an Object via ADDObject method (I haven't tested it 'on the fly' at runtime but have successfully Subclassed it ahead of time):

CmdButton.Init()
THIS.AddObject("LocalDS","MyreportDS")

The Session is completely unaware of the Form's Tables and relationships, etc..
