Hi Vijay,
First of all you have to see this settings in ECC ie. have you created plant as vendor?You have to assign plant to vendor in ECC the same will replicate as Party entitled to dispose in EWM.Once that is over, CIF your vendor in CFM1 select create Loc/BP option -2.Go to EWM and check your BP ,go to identification tab and select ID type as CRM011 -R/3 Plant Number and save it.Check your Party Entitled to Dispose against plant.
Thanks
