Deployed assets are missing While executing data source mapping from ITIC

we did integration between IBM CONTROLDESK with IBM ENDPOINT MANAGER using ITIC(IBM Tivoli Integration Composer), In ITIC we created data source for CONTROLDESK Database and IBM ENDPOINT MANAGER and created mapping between them, and tried to run executemapping.sh with some parameters. mapping completed successfully but i have 10 assets in IBM ENDPOINT MANAGER but after data import to CONTROLDESK , there in deployed assets it is showing 7 assets in Goto>Assets>Deployed assets>computers

some deployed assets are missing from While executing mapping, so what is the reason?? can any one suggest me!!
