deltagen or basearea when iwsyncdb.ipl run

System

I can register specific branch with DAS for metadata . But for the another one , every time I run iwsyncdb.ipl -initial vpath teamsite/metadata , the deployment in command turns to deltagen like messages below

DataDeploy Command=[cfg="/usr/iw-home/local/config/mdc_dd.cfg" deploymen
t=deltagen myarea="/default/main/test/WORKAREA/wa" mybasearea="/default/main/tes
t/STAGING" mytable=DEFAULT_TEAMSITE_METADATA__MAIN_TEST_WORKAREA_WA mybasetable=
DEFAULT_TEAMSITE_METADATA__MAIN_TEST_STAGING mybasetablenameprefix=DEFAULT_TEAMS
ITE_METADATA mybasetablenamesuffix=MAIN_TEST_STAGING mytablenameprefix=DEFAULT_T
EAMSITE_METADATA mytablenamesuffix=MAIN_TEST_WORKAREA_WA mysubpath=. ]

I just see nothing in the table it generated .
Did I mis-configure something or miss some parameter ?
