$TABLE issue when using parallel computing and SAEM/IMP

Hello, Hope someone can guide me. I am running SAEM/IMP. I can get $TABLE output if I am using single core. However, whenever I use multiple cores, I couldn't get the sdtab and patab output from $TABLE (same control stream). Below is the snip of control stream and error message. $ESTIMATION METHOD=SAEM AUTO=1 PRINT=10 NBURN=3000 NITER=1000 RANMETHOD=P $ESTIMATION METHOD=IMP EONLY=1 PRINT=1 NITER=5 ISAMPLE=1000 SEED=12345 MAPITER=0 RANMETHOD=P $COVARIANCE PRINT=E MATRIX=R $TABLE ID EVID MDV TIME DV PRED IPRED CWRES ONEHEADER NOAPPEND NOPRINT FILE=run2.7.sdtab $TABLE ID TLAG TMAX CMAX FOLD FB ALPHA BETA ETA_TLAG ETA_TMAX ETA_CMAX ETA_FOLD ETA_ALPHA ETA_BETA ONEHEADER NOAPPEND NOPRINT FIRSTONLY FILE=run2.7.patab [cid:[email protected]] Really appreciate your help!
