  The SAP error message ECH_MSG100 with the description "Caller is not on the whitelist (PPO order &1)" typically indicates that a specific caller or user is not authorized to perform an action related to a PPO (Purchase Order) in the system. This is part of the security measures in place to ensure that only authorized users can access or modify certain data.
