LCMbiar with schedule option

Hi All

Env: BI4.0 SP6 patch 5 on Linux

I'm trying to schedule a Promotion Job. The goal is to store my LcmBiar file in a specific folder on my Linux server.

The  LCMBiar File Destination is:  File System

AdaptiveJobServer destination properties for File system is:  /usr/sap/ADM1/sap_bobj/data/backup_BI4_content

I tried  using  User Name and pwd, and NOT

When promote the job with schedule option, job failed with message:

Commit Status=Commit attempted and failed., Promotion Status=Failure : Delivery results to destination (CrystalEnterprise.DiskUnmanaged) failed.

Please advice ;-)

Thank you
