Business Partner & Version in cProjects

Hi,

I hav created a Business Partner in front end in R/3 in cProj and assigning it as a resource, but i am getting an error Enter a Valid Business Partner.

Also i am unable to create a proj version.Whenever i am trying to create a version, i eneter a number for e.g. -1, but system gives error Version-1 doen't exsist.I am unable to resolve the prob.

Can anyone guide me on the config part of Business Partners & versions to solve the prob.

Thanks in advance.

Regards

Sarang,
