Logging failed when trying to process cube using default impersonation mode

Problem: When I was trying to process the cube whose source data is on staging .18 and target deployment server is localservice, BIDS reported that service account used

can not access the source.  The service account is the local service account

 

Solution: Go to Control panel on local machine –> services-> find out SSAS service-> Log On tab  and change “This account ” to my windows credentials with passwd
