Authorisation issue with T-code CA85 N for mass update

Dear Security gurus,

  One of the business user in our project is trying to use CA85N to mass update . He needs to bulk update to "X" the CostingRelevncy indicator for all SG35 routings. He has the auth. of T-code but still he is getting the error

"Some task list cannot be changes because you do not ahve authorisations.' I run the trace also and it is showing all sucessful. there is no authorisation missing in trace.

Please help if someone is aware about any reuqired object for this access.

Thanks,

Varun Jain
