how to import with excel import utility a testplan and add schedule (new or existing iteration)

I'm trying to import with excel import utility a testplan with schedule.
I saw that every time im trying to use schedule that alrady defined vor other testplan (already exists under project timeline under a name "testplan <other_tp_ID>) then i see during RQM export all ok:


but after refresching RQM project still is for this testplan the iteration unassigned!

here the schedule part of my cfg file:
//Config for testphase
testphase.XLSWorksheetID="Schedules"
testphase.XLSArtifactID=A
testphase.XLSStartRow=4
testphase.dc:title=B
testphase.dc:description=C
testphase.expectedTotalPoints=D
testphase.expectedDefects=E
testphase.expectedValidityRate=F
testphase.expectedStartDate=G
testphase.expectedEndDate=H
testphase.starttime=I
testphase.endtime=J
testphase.testplan=Link(K4)

and the corresponding xls file:


My question is how to handle this? Were are my mistakes on this topic?
My goal is to create over EXCEL import utility an TP with schedule and environments (using existing iterations and environments).
