No entry for plant xxxx service object 01 in table T399A ?

Hi experts,

                 I am getting 2 errors  1): No entry for plant xxxx service object 01  in table T399A  while doing repair order confirmation. But we are not creating any Service order at Repair order level and we are not using material type is DIEN. We are not maintain any config In the tcode OSID. Even though, we are getting same error. and even we are getting on other ERROR 2): Error when processing service order--> Massage No : V1380. ?

And my Second Requirement is  Auto confirmation of repair order when we receive a Repaired product from Repair sight.That means system has to give Auto confirm at  tcode VA02. Please help me. is there any standard config for Auto confirmation or Enhance at va02.

Thanks in Advance
