Hi Senthil,
What do you mean by APC?
Please elaborate more.
APC = abstract portal component, a simple iView
Do you have any idea with Repository Framework Webservice usage for this requirement? will it help?
No need for WSDL. You will probably need the KMC API: Knowledge Management and Collaboration (KMC) (Netweaver�2004S�SPS 09).
