Unable to add catalog item in Shopping Cart while approving it

Hi gurus,

We're facing an issue where when we submit data back to the SRM shopping cart from the Ariba catalog while approving it (Inquire functionality). I am able to copy and paste as well ad new line items but getting error while selecting items from Ariba Catalog.

In standard Shopping Cart creation with Ariba Catalog its working fine.

But when I am trying to add items from Ariba Catalog while Approving, its fetching the catalog but while returning its giving error.

The error message:

I have checked the services are also active in SICF.

Does anyone know why this is happening and what settings to be done?

Thanks,

Ajit
