Hi Sanjay ! Tnaks for response, I found the reason , I sent record RcVc RepSpec to import function , my bug. But could be nice if hal compiler could warn us about this, or at least, "Link Check" report could show this anomaly.
Actually a new version of this bug is SL>>Reports>>Periodic customer statement "accumulates" amounts
Not sure why it was duplicated, I clicked "submit"only once....
