Hi Vinay,
For your case:-
1.Go to Application Server
2.Explore to C:\Program Files (x86)\CA\ITAM\WCF Service
3.Open web.config file.
4.Look for this tag and set to true. <serviceMetadata httpGetEnabled="true" />
(by default it is false )
Hopefully it will resolve your issue.let me know what happens after doing this.
By the way do you have any idea how could I modify objects in ITAM through ITPAM?
Thanks
Manirul
