Hi Aamir,
When SAM is integrated with ITAM, then you do not integrate Client Automation (ITCM) with ITAM (ie, they should NOT share the same mdb either.)
Integrate Client Automation with SAM by creating 'connectors' that bring in the data from Client Automation to SAM.
See this example on how to implement the Client Automation (ITCM) connector with SAM:
