WEBCATALOG not working in CRM

Hi Gurus,

I am facing some issues on Product catalog Access through my B2c & B2B links of my CRM 5.0 server. The error I am getting is as follows:

<b>"The catalog that you have selected is currently unavailable; try again later"</b>

Before that i had successfully finish following activities:

RFC Connection to TRX server established

Initial Products replication completed successfully (HTTP Link)

Create WebShops using these replicated product catalog(following link)

http://ides01-nsrv.iserviceglobe.com:50000/shopadmin/shopadmin/init.do?

Create Business partner required to login to B2B

After that I am able to see my WEBSHOPs created above but when I click on any shop it gives above error

Please tell me is there any setting required which facilitate data from my HTTP/FTP site to my B2B shoplinks

Regards

Joyce
