Error in importing objects in STMS_IMPORT

Hi Experts,

Urgent!!

I have exported IR & ID objects under one TR (using CTS organizer) from DEV environment. While importing  by using STMS_IMPORT in PI QTY system I got the following error.

RFC communications error with system/destination

%%ashost=BLPIQTY,sysnr=,lang=E,client=220,pcs=2,ic

RFC destination

%%ashost=BLPIQTY,sysnr=,lang=E,client=220,pcs=2,icce=1,cf

it=0x20 does not exist.

Please suggest some way out !!

Thanks,

Arthita
