CRM 2011: How to call a Save event in javascript?

Hi All,

In CRM 2011 i am using Xrm.Page.data.entity.save() method to invoke the save method in my javascript code.

But, this methos is not working for a particular record.
Even CRM entity's save button is also not working for this record.

For other records this is working fine and smoothly. Only i am facing problem for thia record only.

If i assing addition security role of system admin then it working fine and smooth.

any suggetions / ideas ?
