I am getting the following error requiring a global refresh and loss of progress fairly regularly:

Problem : 
The object has been modified by another user since you opened it
Advice : 
Update data with Global refresh before switch

Can someone advise what to do to a) prevent this from occuring and b) to continue the save without losing local changes?

I am only briefly familier with 3D Experience and change management from within a Solidworks context.

Thanks for your help,

Alfie
