Pricing error in CRM

Hi all,

Error: "Header Data: document 479B39A6245B00FFE10080000A8C6528 not existing"

That's the error I get when I try to create the Service Quotation. Pricing Procedure is getting picked but no values found under the conditions Tab(both header and item level). the same message pops up when i try to enter the conditons types.

When i see in the Pricing Procedure it has all the conditions types included in it.

What could be the problem?

Thanx in advance.

Regards
