Hi Krishna,
did you try run Test/Repair model?
For run this function you need switch on Expert Mode. When Expert mode is set you can find it in popupmenu of model.
Test model - log inconsistences in model to Message Explorer
Repair model - repair inconsistences which can be repaired automatically

Hi Daril,

Yes i did repair model and came to know that issue is with some specific entities. not sure what is the exact issue with them. I created whole datamodel again from scratch and now it is complete without any issues.

Thank you for your inputs.
